Walkthrough

This change introduces a complete example project for a music licensing application built with Next.js, React, Apollo Client, and TypeScript. The project includes comprehensive configuration files, environment variable templates, middleware for authentication, and a full set of React components for UI, navigation, and data display. GraphQL queries, mutations, and subscriptions are defined for movies, scenes, tracks, songs, and license statuses. The codebase features authentication integration using NextAuth, server and client utility functions, global styling with Tailwind CSS, and developer tooling for linting, formatting, and type-checking. The project is structured with clear separation of concerns and centralized route and type definitions.

Poem

In a garden of code where the music flows,
A new app sprouts where the melody grows.
With routes and hooks, and queries so bright,
Songs and movies shimmer in Tailwind light.
Auth guards the gates, Apollo brings news—
Real-time updates, no time to snooze!
🐇 Here's to the launch—let's dance in the code dew!

🧹 Nitpick comments (55)
examples/music-licensing-challenge-nextjs/.husky/pre-push (1)

1-4: Review package manager consistency

The script uses npm run type-check but according to other files in the project (like the pre-commit hook mentioned in the summary), the project appears to use pnpm. Consider updating to pnpm run type-check for consistency across the project's scripts.

#!/usr/bin/sh
. "$(dirname "$0")/_/husky.sh"

-npm run type-check
+pnpm run type-check
examples/music-licensing-challenge-nextjs/src/app/not-found.tsx (1)

1-9: Consider adding "use client" directive

If you plan to add interactive elements to this page (like the suggested navigation button), you should mark it as a client component.

+"use client";
+
const NotFoundPage = () => {
	return (
		<>
			<h1>Page Not Found</h1>
		</>
	);
};

export default NotFoundPage;
examples/music-licensing-challenge-nextjs/src/lib/graphql/mutations/songs.ts (1)

1-10: Clean and well-structured GraphQL mutation definition

The UPDATE_SONG_LICENSE_STATUS mutation is correctly defined using Apollo Client's gql tag and follows good GraphQL practices by requesting only the necessary fields in the response.

Consider adding a comment about what values the LicenseStatusEnum can have to improve code readability for developers who might not be familiar with the GraphQL schema.

examples/music-licensing-challenge-nextjs/next.config.ts (1)

12-14: Consider enabling ESLint during builds for better code quality

Setting ignoreDuringBuilds: true for ESLint means that linting errors won't prevent builds, which could lead to code quality issues making it to production.

This might be appropriate for rapid development cycles, but consider changing this to false before production deployment to enforce code quality standards:

eslint: {
-	ignoreDuringBuilds: true,
+	ignoreDuringBuilds: process.env.NODE_ENV !== 'production',
},

This would allow ignoring linting errors during development builds but enforce them for production builds.

examples/music-licensing-challenge-nextjs/src/app/page.tsx (1)

5-16: Add responsive styling for mobile devices

The current implementation has a fixed text size that may not work well on smaller screens.

Add responsive typography for better mobile experience:

<main className="flex flex-col items-center justify-center h-screen text-center">
-	<h1 className="text-6xl font-bold mb-4">
+	<h1 className="text-3xl md:text-4xl lg:text-6xl font-bold mb-4 px-4">
		Welcome to our Music Licensing App!
	</h1>
	{/* Button component here */}
</main>
examples/music-licensing-challenge-nextjs/env.example (2)

1-7: Add documentation for environment variables

The environment variables template is good for setup, but lacks explanatory comments about the purpose of each variable.

Consider adding comments to help developers understand what each variable is for:

-NEXT_PUBLIC_API_BASE_URL=
+# Base URL for API requests
+NEXT_PUBLIC_API_BASE_URL=

-NEXT_PUBLIC_AUTH_SECRET=
+# Secret key for authentication
+NEXT_PUBLIC_AUTH_SECRET=

-NEXT_PUBLIC_USER_EXAMPLE=
-NEXT_PUBLIC_PASSWORD_EXAMPLE=
+# Example credentials (consider moving these to README instead)
+NEXT_PUBLIC_USER_EXAMPLE=
+NEXT_PUBLIC_PASSWORD_EXAMPLE=

-NEXT_PUBLIC_WS_URL=
+# WebSocket URL for GraphQL subscriptions
+NEXT_PUBLIC_WS_URL=

-NEXT_PUBLIC_GRAPHQL_URL=
+# GraphQL endpoint URL
+NEXT_PUBLIC_GRAPHQL_URL=

-NEXTAUTH_URL=
+# URL for NextAuth.js
+NEXTAUTH_URL=

3-4: Consider moving example credentials to documentation

Storing example credentials in environment variables is not a best practice from a security perspective.

It would be better to move these example credentials to the README or documentation rather than including them in the environment template. This helps prevent them from being accidentally used in production environments.

examples/music-licensing-challenge-nextjs/src/hooks/useSongWithLiveStatus.tsx (2)

1-5: Consider renaming file extension from .tsx to .ts

This file doesn't contain any JSX elements, so it should use the .ts extension rather than .tsx.


7-20: Consider using Apollo Client context instead of direct import

For better testability, consider accessing the Apollo client through context rather than direct import.

-import { client } from "@/lib/graphql/client";
+import { useApolloClient } from "@apollo/client";

 export function useSongWithLiveStatus(song: Song) {
+	const client = useApolloClient();
 	const { data: subscriptionData } = useSubscription(LICENSE_STATUS_UPDATED, {
 		variables: { id: song.id },
 		client,
 	});

This makes the hook more testable as you can mock the Apollo client during tests.

examples/music-licensing-challenge-nextjs/src/components/SceneList/getLicensesOptions.tsx (1)

19-20: Fix variable name typo

There's a typo in the variable name licenseSStatusOptions (extra 'S'). Also, consider handling loading and error states from the query.

-	const licenseSStatusOptions = queryData?.allLicenseStatus || []
+	const licenseStatusOptions = queryData?.allLicenseStatus || []
-	return licenseSStatusOptions.map((value: LicenseStatus) => ({
+	return licenseStatusOptions.map((value: LicenseStatus) => ({
examples/music-licensing-challenge-nextjs/src/components/SceneList/SceneItem.tsx (1)

4-7: Add memo for better performance

Consider memoizing the component to prevent unnecessary re-renders when parent components update but the scene data hasn't changed.

+import { memo } from "react";
 import { TrackItem } from "./TrackItem";
 import type { Scene } from "@/types";
 
-export const SceneItem = ({
+export const SceneItem = memo(({
 	scene,
 	isEditable = false,
-}: { scene: Scene; isEditable?: boolean }) => (
+}: { scene: Scene; isEditable?: boolean }) => (
 	<li className="bg-white dark:bg-gray-800 rounded-2xl shadow-md p-4 border border-gray-200 dark:border-gray-700 list-none">
 		<p className="text-lg font-semibold text-gray-800 dark:text-gray-200">
 			Scene {scene.scene_number}
 		</p>
 		<p className="text-gray-600 dark:text-gray-400 mb-4">{scene.description}</p>
 		<ul className="space-y-4">
 			{scene.tracks.map((track) => (
 				<TrackItem key={track.id} track={track} isEditable={isEditable} />
 			))}
 		</ul>
 	</li>
-);
+));
+
+SceneItem.displayName = "SceneItem";
examples/music-licensing-challenge-nextjs/src/lib/graphql/client.ts (2)

6-7: Add error handling for missing GraphQL endpoint URL

The HTTP link setup doesn't handle cases where the environment variable might be undefined.

const httpLink = new HttpLink({
-	uri: process.env.NEXT_PUBLIC_GRAPHQL_URL,
+	uri: process.env.NEXT_PUBLIC_GRAPHQL_URL || '/graphql',
});

Alternatively, add explicit error checking:

+if (!process.env.NEXT_PUBLIC_GRAPHQL_URL) {
+  console.error('NEXT_PUBLIC_GRAPHQL_URL is not defined');
+}

const httpLink = new HttpLink({
	uri: process.env.NEXT_PUBLIC_GRAPHQL_URL,
});

21-24: Consider enhancing Apollo client configuration

The current Apollo client configuration is minimal. Consider adding more robust options:

export const client = new ApolloClient({
	link: splitLink,
-	cache: new InMemoryCache(),
+	cache: new InMemoryCache({
+		typePolicies: {
+			// Define type policies for better cache behavior
+		},
+	}),
+	defaultOptions: {
+		watchQuery: {
+			fetchPolicy: 'cache-and-network',
+			errorPolicy: 'ignore',
+		},
+		query: {
+			fetchPolicy: 'network-only',
+			errorPolicy: 'all',
+		},
+		mutate: {
+			errorPolicy: 'all',
+		},
+	},
});

These options provide better error handling and more predictable caching behavior.

examples/music-licensing-challenge-nextjs/src/middleware/auth.ts (1)

11-11: Replace console.log with proper logging for production

Using console.log for logging in production code is not recommended:

- console.log("No token found, redirecting to login");
+ // Use a proper logging solution that can be configured based on environment
+ // logger.info("No token found, redirecting to login");

Consider implementing a structured logging solution that can be configured differently based on the environment.

examples/music-licensing-challenge-nextjs/src/components/SceneList/index.tsx (2)

6-19: Add empty state handling

Currently, if the scenes array is empty, the component renders an empty <ul>. Provide feedback to users when no data is available:

const ScenesList = ({ scenes }: { scenes: Scene[] }) => {
	return (
		<ul className="flex flex-col space-y-6 mt-4">
+			{scenes.length === 0 ? (
+				<li className="text-center p-4 text-gray-500">
+					No scenes available
+				</li>
+			) : (
				{scenes.map((scene) => (
					<Link
						key={scene.id}
						href={`${APP_ROUTES.SCENE_DETAILS.path}/${scene.id}`}
					>
						<SceneItem scene={scene} />
					</Link>
				))}
+			)}
		</ul>
	);
};

This improves the user experience by providing clear feedback when no data is available.


10-15: Add visual feedback for clickable items

Add subtle visual cues to indicate that scene items are clickable:

<Link
	key={scene.id}
	href={`${APP_ROUTES.SCENE_DETAILS.path}/${scene.id}`}
+	className="transition-transform hover:scale-[1.01] cursor-pointer"
>
	<SceneItem scene={scene} />
</Link>

This provides visual feedback that improves usability by indicating the interactive nature of these elements.

examples/music-licensing-challenge-nextjs/src/components/SceneList/TrackItem.tsx (1)

12-17: Consider using a more unique key for list items

Using song.title as the key for list items might cause issues if there are multiple songs with the same title within a track. Consider using a more unique identifier such as song.id if available.

-				<SongItem key={song.title} song={song} isEditable={isEditable} />
+				<SongItem key={song.id} song={song} isEditable={isEditable} />
examples/music-licensing-challenge-nextjs/src/app/(movies)/movies/page.tsx (1)

16-29: Consider adding a fallback for undefined allMovies

While you're checking for allMovies?.length === 0, there's no handling for if allMovies is undefined. Consider adding a null check or providing a default empty array.

<div className="grid lg:grid-cols-3 sm:grid-cols-2 grid-cols-1 gap-16">
-	{allMovies?.length === 0 ? (
+	{!allMovies || allMovies.length === 0 ? (
		<p>No movies available.</p>
	) : (
-		allMovies?.map((movie) => (
+		allMovies.map((movie) => (
			<MovieCard key={movie.id} movie={movie} showActionButton />
		))
	)}
</div>
examples/music-licensing-challenge-nextjs/src/auth/index.ts (1)

7-35: Enhance the user object with additional properties

The current implementation only returns the user's email. Consider adding more properties to the user object, such as an ID or name, which might be useful for the application.

Also, line 34 uses NEXT_PUBLIC_AUTH_SECRET which should be a server-side environment variable for security reasons.

if (
	credentials?.email === userExample &&
	credentials?.password === passwordExample
) {
-	return { email: userExample };
+	return { 
+		id: '1', // Or generate a unique ID
+		email: userExample,
+		name: 'Example User'
+	};
}

// And update the secret:
-secret: process.env.NEXT_PUBLIC_AUTH_SECRET,
+secret: process.env.AUTH_SECRET,
examples/music-licensing-challenge-nextjs/src/lib/graphql/queries/scenes.ts (3)

3-22: Consider using GraphQL fragments for code reuse

Both queries fetch the same fields for scene data. A GraphQL fragment would reduce duplication and make it easier to maintain consistent field selection across queries.

Here's how you could implement it:

import { gql } from "@apollo/client";

+const SCENE_FIELDS = gql`
+  fragment SceneFields on Scene {
+    id
+    movieId
+    sceneNumber
+    description
+    tracks {
+      id
+      trackType
+      songs {
+        id
+        title
+        artist
+        licenseStatus
+      }
+    }
+  }
+`;

export const GET_SCENES = gql`
  query GetAllScenes {
    allScenes {
-      id
-      movieId
-      sceneNumber
-      description
-      tracks {
-        id
-        trackType
-        songs {
-          id
-          title
-          artist
-          licenseStatus
-        }
-      }
+      ...SceneFields
    }
  }
+  ${SCENE_FIELDS}
`;

export const GET_SCENE_BY_ID = gql`
  query GetSceneById($id: ID!) {
    scene(id: $id) {
-      id
-      movieId
-      sceneNumber
-      description
-      tracks {
-        id
-        trackType
-        songs {
-          id
-          title
-          artist
-          licenseStatus
-        }
-      }
+      ...SceneFields
    }
  }
+  ${SCENE_FIELDS}
`;

Also applies to: 24-43


3-22: Consider implementing pagination for scalability

The GET_SCENES query fetches all scenes without pagination, which could lead to performance issues as the dataset grows.

Consider adding pagination parameters:

export const GET_SCENES = gql`
-  query GetAllScenes {
+  query GetAllScenes($first: Int, $after: String) {
-    allScenes {
+    allScenes(first: $first, after: $after) {
      id
      movieId
      sceneNumber
      description
      tracks {
        id
        trackType
        songs {
          id
          title
          artist
          licenseStatus
        }
      }
+     pageInfo {
+       hasNextPage
+       endCursor
+     }
    }
  }
`;

1-44: Add TypeScript interfaces for query responses

Adding TypeScript interfaces for the expected response data would improve type safety when these queries are used in components.

Consider adding interfaces in a types file or at the top of this file:

export interface Song {
  id: string;
  title: string;
  artist: string;
  licenseStatus: string;
}

export interface Track {
  id: string;
  trackType: string;
  songs: Song[];
}

export interface Scene {
  id: string;
  movieId: string;
  sceneNumber: number;
  description: string;
  tracks: Track[];
}

export interface GetScenesResponse {
  allScenes: Scene[];
}

export interface GetSceneByIdResponse {
  scene: Scene;
}
examples/music-licensing-challenge-nextjs/src/components/Navbar/actionButtons.tsx (2)

10-20: Add loading state and error handling to the SignOutButton

The button currently doesn't provide feedback during the logout process or handle potential errors.

Consider adding loading state and error handling:

"use client";

import Link from "next/link";
+import { useState } from "react";
import { logOut } from "@/lib/auth";
import { APP_ROUTES } from "@/routes";

const buttonStyles =
	"hover:bg-gray-100 block w-full px-4 py-2 text-left text-sm text-gray-700";

export const SignOutButton = () => {
+	const [isLoading, setIsLoading] = useState(false);
+	const [error, setError] = useState<string | null>(null);
+
+	const handleSignOut = async () => {
+		try {
+			setIsLoading(true);
+			setError(null);
+			await logOut();
+		} catch (err) {
+			setError("Failed to sign out. Please try again.");
+			console.error(err);
+		} finally {
+			setIsLoading(false);
+		}
+	};
+
	return (
		<button
			type="button"
-			onClick={async () => logOut()}
+			onClick={handleSignOut}
+			disabled={isLoading}
			className={buttonStyles}
		>
-			Sign out
+			{isLoading ? "Signing out..." : "Sign out"}
+			{error && <span className="text-red-500 text-xs ml-2">{error}</span>}
		</button>
	);
};

7-34: Enhance accessibility for navigation and action buttons

The buttons lack appropriate ARIA attributes for accessibility.

Add ARIA attributes to improve accessibility:

const buttonStyles =
	"hover:bg-gray-100 block w-full px-4 py-2 text-left text-sm text-gray-700";

export const SignOutButton = () => {
	return (
		<button
			type="button"

12-40: Use more semantic HTML for the movie details

Using the description list (dl, dt, dd) elements would be more semantically appropriate for this key-value data.

Consider using semantic HTML elements:

const MovieDetails: React.FC<MovieDetailsProps> = ({ movie }) => {
	const movieDetailsFields: MovieDetailField[] = [
		{ label: "Year", value: movie.year },
		{ label: "Genre", value: movie.genre },
		{ label: "Director", value: movie.director },
		{ label: "Total Scenes", value: movie.scenes.length },
		{
			label: "Total Tracks",
			value: movie.scenes.reduce(
				(total, scene) => total + scene.tracks.length,
				0,
			),
		},
		{ label: "Description", value: movie.description },
	];

	return (
-		<div className="flex flex-col gap-4">
-			{movieDetailsFields.map((field) => (
-				<p key={movie.id}>
-					<span className="font-bold">{field.label}: </span>
-					<span className="text-gray-700">
-						{Array.isArray(field.value) ? field.value.join(", ") : field.value}
-					</span>
-				</p>
-			))}
-		</div>
+		<dl className="grid grid-cols-[auto_1fr] gap-x-2 gap-y-4">
+			{movieDetailsFields.map((field) => (
+				<>
+					<dt key={`${field.label}-term`} className="font-bold">{field.label}:</dt>
+					<dd key={`${field.label}-desc`} className="text-gray-700">
+						{Array.isArray(field.value) ? field.value.join(", ") : field.value}
+					</dd>
+				</>
+			))}
+		</dl>
	);
};

Note: The fragment (<>) with two keys is not optimal. A better solution would be to map to an array of objects and then render:

return (
  <dl className="grid grid-cols-[auto_1fr] gap-x-2 gap-y-4">
    {movieDetailsFields.flatMap((field) => [
      <dt key={`${field.label}-term`} className="font-bold">{field.label}:</dt>,
      <dd key={`${field.label}-desc`} className="text-gray-700">
        {Array.isArray(field.value) ? field.value.join(", ") : field.value}
      </dd>
    ])}
  </dl>
);

18-24: Add null check for nested properties in the reduce function

The reduce function assumes that every scene has a tracks property, which might cause runtime errors if the data structure doesn't match this assumption.

Add null checks to prevent potential errors:

{
	label: "Total Tracks",
	value: movie.scenes.reduce(
-		(total, scene) => total + scene.tracks.length,
+		(total, scene) => total + (scene.tracks?.length || 0),
		0,
	),
},
examples/music-licensing-challenge-nextjs/src/routes/index.ts (2)

1-44: Add TypeScript interface for route configuration

Adding a TypeScript interface for the route configuration would improve type safety and documentation.

Consider adding an interface at the top of the file:

+interface RouteConfig {
+  path: string;
+  name: string;
+  isNavbarItem: boolean;
+  isProtected: boolean;
+}
+
+interface AppRoutes {
+  [key: string]: RouteConfig;
+}
+
-export const APP_ROUTES = {
+export const APP_ROUTES: AppRoutes = {
	HOME: {
		path: "/",
		name: "Home",
		isNavbarItem: false,
		isProtected: false,
	},
	// ... other routes
};

1-44: Consider adding routes for error states

The routes configuration doesn't include entries for handling error states like 404 (not found) pages.

Add routes for error states:

export const APP_ROUTES = {
	// ... existing routes
+	NOT_FOUND: {
+		path: "/404",
+		name: "Page Not Found",
+		isNavbarItem: false,
+		isProtected: false,
+	},
+	ERROR: {
+		path: "/error",
+		name: "Error",
+		isNavbarItem: false, 
+		isProtected: false,
+	},
};
examples/music-licensing-challenge-nextjs/src/components/MovieCard/index.tsx (1)

13-22: Consider optimizing the Image component implementation

The Image component uses both fill and sizes="33vw" properties. While fill makes the image expand to fill its parent container, the sizes attribute might not have the expected effect in this context. Consider using either a fixed size approach or the fill approach, but not mixing both.

<div className="relative h-80">
  <Image
    className="rounded-t-lg mx-auto !max-w-3xs"
    src={movie.poster}
    alt={movie.title}
    loading="lazy"
-   sizes="33vw"
    fill
+   style={{ objectFit: 'contain' }}
  />
</div>
examples/music-licensing-challenge-nextjs/src/components/LoginForm/index.tsx (3)

42-50: Add autocomplete attribute to email input

Adding appropriate autocomplete attributes helps browsers fill in form data correctly and improves user experience.

<input
  className="shadow appearance-none border rounded w-full py-2 px-3 text-gray-700 leading-tight focus:outline-none focus:shadow-outline"
  id="email"
  name="email"
  type="email"
  placeholder="Email"
+ autocomplete="email"
  value={credentials.email}
  onChange={handleChange}
/>

59-67: Add autocomplete and improve password input field

Similar to the email field, adding appropriate autocomplete attributes helps browsers fill in password data correctly. Additionally, consider adding aria-describedby for potential password requirements.

<input
  className="shadow appearance-none border rounded w-full py-2 px-3 text-gray-700 mb-3 leading-tight focus:outline-none focus:shadow-outline"
  id="password"
  name="password"
  type="password"
  placeholder="Password"
+ autocomplete="current-password"
+ aria-describedby="password-requirements"
  value={credentials.password}
  onChange={handleChange}
/>

5-15: Consider adding validation state to the form props interface

The current props interface doesn't include any validation state for individual fields. This would be useful for showing field-specific validation errors.

interface LoginFormProps {
  credentials: {
    email: string;
    password: string;
  };
  error: string;
+ validation?: {
+   email?: string;
+   password?: string;
+ };
  handleSubmit: (event: React.FormEvent<HTMLFormElement>) => void;
  handleChange: (event: React.ChangeEvent<HTMLInputElement>) => void;
  loading: boolean;
  disableLoginButton: boolean;
}

This would allow you to display field-specific validation messages below each input field.

examples/music-licensing-challenge-nextjs/src/app/layout.tsx (1)

29-29: Consider browser compatibility for modern CSS properties

The h-dvh class uses the modern dynamic viewport height property, which might not be supported in all browsers. Consider adding a fallback.

-<div className="grid grid-rows-[auto_1fr_auto] h-dvh">
+<div className="grid grid-rows-[auto_1fr_auto] h-screen h-dvh">

This will use height: 100vh as a fallback for browsers that don't support dvh.

examples/music-licensing-challenge-nextjs/src/lib/auth/index.ts (1)

21-23: Add error handling to getSession function

The getSession function should include error handling as well.

export const getSession = async () => {
+ try {
    return await auth();
+ } catch (error) {
+   console.error("Session error:", error);
+   return null;
+ }
};
examples/music-licensing-challenge-nextjs/src/components/Button/index.tsx (1)

1-22: Well-structured reusable Button component

The Button component is well-implemented with proper TypeScript types, clean composition pattern using Headless UI, and consistent styling with Tailwind CSS.

Consider adding support for different button variants (primary, secondary, danger, etc.) if the application requires multiple button styles. This could be implemented by accepting a variant prop:

 interface ButtonProps extends ButtonHTMLAttributes<HTMLButtonElement> {
 	children: ReactNode;
 	className?: string;
+	variant?: 'primary' | 'secondary' | 'danger';
 }

-export const Button = ({ children, className, ...props }: ButtonProps) => {
+export const Button = ({ children, className, variant = 'primary', ...props }: ButtonProps) => {
+	const variantClasses = {
+		primary: "bg-gray-700 text-white data-[hover]:bg-gray-600",
+		secondary: "bg-gray-200 text-gray-800 data-[hover]:bg-gray-300",
+		danger: "bg-red-600 text-white data-[hover]:bg-red-700"
+	};
 	return (
 		<BaseButton
 			className={clsx(
-				"inline-flex items-center gap-2 rounded-md bg-gray-700 py-2 px-16 text-sm/6 font-semibold text-white shadow-inner shadow-white/10 focus:outline-none data-[hover]:bg-gray-600 data-[open]:bg-gray-700 data-[focus]:outline-1 data-[focus]:outline-white",
+				"inline-flex items-center gap-2 rounded-md py-2 px-16 text-sm/6 font-semibold shadow-inner shadow-white/10 focus:outline-none data-[open]:bg-gray-700 data-[focus]:outline-1 data-[focus]:outline-white",
+				variantClasses[variant],
 				className,
 			)}
 			{...props}
 		>
examples/music-licensing-challenge-nextjs/src/app/(movies)/movies/[movieId]/page.tsx (2)

33-40: Improve accessibility with semantic HTML elements

The movie details section could benefit from more semantic HTML elements to improve accessibility.

 				<div className="flex flex-col mx-auto xl:max-w-1/2">
-					<div>
+					<section aria-label="Movie poster">
 						<MovieCard movie={movie} />
-					</div>
-					<div className="mt-6">
+					</section>
+					<section aria-label="Movie information" className="mt-6">
 						<MovieDetails movie={movie} />
-					</div>
+					</section>
 				</div>

31-31: Use semantic heading for better document structure

The page heading should be an h1 element, but it lacks semantic value beyond styling.

-			<h1 className="text-2xl mb-20">Movie Details</h1>
+			<h1 className="text-2xl mb-20 font-bold" id="page-title">Movie Details</h1>
examples/music-licensing-challenge-nextjs/src/app/(auth)/login/page.tsx (3)

8-13: Add basic email validation for better user experience

The login component doesn't perform any client-side validation on the email format before submission.

 const LoginPage = () => {
 	const [credentials, setCredentials] = useState({
 		email: "",
 		password: "",
 	});
 	const [loading, setLoading] = useState(false);
 	const [error, setError] = useState("");
+	const [emailError, setEmailError] = useState("");
+
+	const validateEmail = (email: string) => {
+		const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
+		if (!email) {
+			return "";
+		}
+		return emailRegex.test(email) ? "" : "Please enter a valid email address";
+	};

And then update the handleChange function:

 const handleChange = (event: React.ChangeEvent<HTMLInputElement>) => {
 		setError("");
 		setCredentials({ ...credentials, [event.target.name]: event.target.value });
+		if (event.target.name === "email") {
+			setEmailError(validateEmail(event.target.value));
+		}
 	};

Then pass emailError to the LoginForm component:

 <LoginForm
 	credentials={credentials}
 	error={error}
+	emailError={emailError}
 	handleSubmit={handleSubmit}
 	handleChange={handleChange}
 	loading={loading}
-	disableLoginButton={disableLoginButton}
+	disableLoginButton={disableLoginButton || !!emailError}
 />

35-36: Include more descriptive disable condition comment

The condition for disabling the login button could be more descriptive to make the code more maintainable.

-	const disableLoginButton =
-		loading || !credentials.email || !credentials.password;
+	// Disable login button if: loading, missing email, or missing password
+	const disableLoginButton = 
+		loading || !credentials.email.trim() || !credentials.password.trim();

38-50: Consider adding loading indicator feedback and improving layout

The login page could benefit from visual feedback during loading and improved layout structure.

 	return (
-		<div className="flex flex-col items-center justify-center my-auto h-full">
-			<h1 className="text-3xl font-bold mb-6">Login Page</h1>
+		<main className="flex flex-col items-center justify-center my-auto h-full max-w-md mx-auto p-4">
+			<h1 className="text-3xl font-bold mb-6">Log in to your account</h1>
 			<LoginForm
 				credentials={credentials}
 				error={error}
 				handleSubmit={handleSubmit}
 				handleChange={handleChange}
 				loading={loading}
 				disableLoginButton={disableLoginButton}
 			/>
-		</div>
+		</main>
 	);
examples/music-licensing-challenge-nextjs/biome.json (2)

5-6: Consider enabling VCS integration for better developer experience

VCS integration is currently disabled, but enabling it would improve the developer experience by only linting and formatting files that have changed according to version control.

 	"vcs": {
-		"enabled": false,
+		"enabled": true,
 		"clientKind": "git",
-		"useIgnoreFile": false
+		"useIgnoreFile": true
 	},

24-26: Consider strengthening array index key rule to error level

The "noArrayIndexKey" rule is currently set to "warn", but using array indices as keys can cause serious performance and correctness issues in React.

 			"suspicious": {
-				"noArrayIndexKey": "warn"
+				"noArrayIndexKey": "error"
 			},
examples/music-licensing-challenge-nextjs/src/utils/getMoviesData.ts (1)

17-44: Consider implementing caching to reduce redundant API calls.

The function is well-structured but might lead to redundant API calls when used in different contexts. Consider implementing a simple caching mechanism or using React Query/SWR for data fetching to avoid unnecessary network requests.

Also, the return statement on line 39 is unreachable since all conditions have already been handled above it.

export const getMoviesData = async ({
  movieId,
  sceneId,
}: {
  movieId?: string;
  sceneId?: string;
}): Promise<MoviesData[] | MoviesData | Scene | null> => {
  try {
    const movies = await fetchMoviesData();

    if (!movieId && !sceneId) {
      return movies;
    }

    if (sceneId) {
      return findSceneById(movies, sceneId);
    }

    if (movieId) {
      return movies.find((movie) => movie.id === movieId) || null;
    }

-   return movies;
  } catch (error) {
    console.error("Error fetching movies data:", error);
    return null;
  }
};
examples/music-licensing-challenge-nextjs/src/middleware.ts (1)

6-25: Use NextResponse consistently for redirects.

The middleware uses Response.redirect for the login redirect but NextResponse for other operations. For consistency, consider using NextResponse.redirect for all redirects.

if (request.auth && request.nextUrl.pathname === APP_ROUTES.LOGIN.path) {
  const newUrl = new URL(APP_ROUTES.HOME.path, request.nextUrl.origin);
-  return Response.redirect(newUrl);
+  return NextResponse.redirect(newUrl);
}
examples/music-licensing-challenge-nextjs/src/types/index.ts (2)

1-6: Consider using string literals for license status values.

Instead of using a plain string for licenseStatus, consider using a string literal union type to enforce valid status values and improve type safety.

+export type LicenseStatusValue = "LICENSED" | "PENDING" | "NOT_LICENSED";

export interface Song {
  id: string;
  title: string;
  artist: string;
-  licenseStatus: string;
+  licenseStatus: LicenseStatusValue;
}

32-35: Consider linking LicenseStatus with Song interface.

The LicenseStatus type seems disconnected from the Song interface even though they're related. Consider creating a clear relationship between them or consolidating the types.

+export type LicenseStatusValue = "LICENSED" | "PENDING" | "NOT_LICENSED";

export interface Song {
  id: string;
  title: string;
  artist: string;
-  licenseStatus: string;
+  licenseStatus: LicenseStatusValue;
}

export type LicenseStatus = {
  id: number;
  status: LicenseStatusValue;
};
examples/music-licensing-challenge-nextjs/src/components/SceneList/SongItem.tsx (2)

11-14: Add display name for improved debugging.

Consider adding a display name to your forwardRef component for better debugging experience in React DevTools.

export const SongItem = forwardRef<
  HTMLLIElement,
  { song: Song; isEditable?: boolean }
>(({ song, isEditable = false }, ref) => {
  // Component implementation
});
+SongItem.displayName = "SongItem";

15-16: Consider handling loading states.

The component fetches data but doesn't handle loading states. Consider adding a loading indicator when status is being fetched.

const currentSong = useSongWithLiveStatus(song);
const options = getLicensesOptions(song.id);
+const isLoading = !currentSong;

1-1: Consider using standard Tailwind directives instead of import

While @import "tailwindcss"; works, the recommended approach for Next.js 15 projects is to use the standard Tailwind directives:

-@import "tailwindcss";
+@tailwind base;
+@tailwind components;
+@tailwind utilities;

This follows Tailwind's official documentation and ensures proper loading of all Tailwind features including base styles, component classes, and utility classes.

examples/music-licensing-challenge-nextjs/src/components/SceneList/MenuButtonContent.tsx (1)

3-11: Make the text content customizable for better reusability

The component currently hardcodes the "Edit" text, which limits its reusability in different contexts. Consider making the text content customizable through props:

-const MenuButtonContent = () => (
+interface MenuButtonContentProps {
+  text?: string;
+}
+
+const MenuButtonContent = ({ text = 'Edit' }: MenuButtonContentProps) => (
 	<>
-		Edit
+		{text}
 		<ChevronDownIcon
 			aria-hidden="true"
 			className="-mr-1 size-5 text-gray-400"
 		/>
 	</>
 );

This would allow the component to be used in various contexts beyond just editing.

examples/music-licensing-challenge-nextjs/src/components/Dropdown/index.tsx (1)

17-54: Enhance component with selection callbacks and empty state handling

The component is well implemented but could benefit from these improvements:

  1. Add an onSelect callback to capture option selection events
  2. Add empty state handling when no options are available
  3. Add position customization for the dropdown menu
 interface DropdownProps {
 	options: DropdownOption[];
 	menuButtonContent?: React.ReactNode;
 	className?: string;
+	onSelect?: (label: string) => void;
+	position?: 'left' | 'right' | 'center';
+	emptyStateMessage?: string;
 }

 const Dropdown = ({
 	options = [],
 	menuButtonContent,
 	className,
+	onSelect,
+	position = 'right',
+	emptyStateMessage = 'No options available',
 }: DropdownProps) => {
 	return (

examples/music-licensing-challenge-nextjs/.husky/pre-commit (1)

1-4: This pre-commit hook setup looks good!

The pre-commit hook script is correctly configured to run lint-staged via pnpm, ensuring code quality checks before each commit.

Two things to verify (not visible in the code review):

  1. Make sure this file has executable permissions (chmod +x .husky/pre-commit)
  2. Confirm that lint-staged is properly configured in package.json or a dedicated config file
examples/music-licensing-challenge-nextjs/next-env.d.ts (1)

1-6: LGTM: Standard Next.js TypeScript declarations

This is the standard TypeScript declaration file for Next.js and should not be modified as noted in the comment.

examples/music-licensing-challenge-nextjs/src/lib/graphql/queries/licenses.ts (1)

1-10: Query Definition Looks Good
The GET_LICENSE_STATUS query correctly retrieves id and status from allLicenseStatus. Ensure that your GraphQL schema matches this shape and that any generated TypeScript types via your codegen pipeline are up to date.

examples/music-licensing-challenge-nextjs/src/lib/graphql/queries/songs.ts (1)

1-13: Song Query Implementation is Correct
The GET_SONG_BY_ID query fetches the necessary fields (id, title, artist, licenseStatus) and follows naming conventions. Verify that your UI components (e.g., useSongWithLiveStatus and SongItem) consume this data correctly and that types are generated if you use GraphQL codegen.

examples/music-licensing-challenge-nextjs/src/app/api/auth/[...nextauth]/route.ts (1)

1-3: Auth route implementation follows Next.js best practices

This file correctly implements the Next.js API route for NextAuth using the catchall route pattern [...nextauth]. The implementation properly imports and re-exports the handlers from the centralized auth configuration, which is a good practice for maintainability.

examples/music-licensing-challenge-nextjs/src/lib/graphql/subscriptions/license-status.ts (1)

3-11: GraphQL subscription looks well-structured

The LICENSE_STATUS_UPDATED subscription is well-defined with the necessary fields to track license status changes. This will work effectively for real-time updates.

examples/music-licensing-challenge-nextjs/.gitignore (1)

1-41: Well-structured .gitignore file

The .gitignore file is comprehensive and follows best practices for Next.js projects. It properly excludes:

  • Node.js dependencies and package manager files
  • Testing artifacts
  • Build outputs
  • System files
  • Debug logs
  • Environment files (important for security)
  • Deployment configurations
  • TypeScript build artifacts

The clear section comments make it easy to understand and maintain.

examples/music-licensing-challenge-nextjs/src/components/SceneList/TrackItem.tsx (1)

1-7: Looks good: Clean component definition with proper typing

The component is properly defined with TypeScript typing for the props, and the default value for isEditable is correctly set to false.

examples/music-licensing-challenge-nextjs/src/app/(movies)/movies/page.tsx (2)

1-9: LGTM: Well-structured type definitions and imports

The imports and type definitions are clean and appropriate. Good job defining the Movies type to properly type the GraphQL query response.


30-32: LGTM: Clean component export

The component is properly defined as an async function and exported as default, which is consistent with Next.js page patterns.

examples/music-licensing-challenge-nextjs/src/components/Navbar/getNavbarLinks.tsx (3)

1-4: LGTM: Clean imports

The imports are well organized and properly reference the necessary components and functions.


5-20: Well-structured function with proper typing

The getNavbarLinks function is well implemented, filtering out routes that aren't navbar items and properly typing the returned array. Good use of filter and map functions.


22-43: LGTM: Good implementation of conditional menu options

The getMenuOptions function correctly handles the authenticated and unauthenticated states, returning the appropriate menu options based on the session. The async/await pattern is used correctly for fetching the session.

examples/music-licensing-challenge-nextjs/tsconfig.json (1)

1-27: Well-configured TypeScript settings for Next.js

The TypeScript configuration follows the recommended practices for a Next.js project. It has appropriate compiler options including strict type checking, module resolution settings, and path aliasing.

examples/music-licensing-challenge-nextjs/src/lib/graphql/queries/movies.ts (2)

36-67: Consistent movie detail query structure

The GET_MOVIE_BY_ID query maintains the same structure as GET_MOVIES, ensuring consistency across the application. The query parameter is correctly typed.


3-34:

❓ Verification inconclusive

Well-structured GraphQL query for retrieving all movies

The GET_MOVIES query is well-structured with complete movie data, including deeply nested related entities (scenes, tracks, songs).

The deeply nested structure might result in large payloads. Consider whether pagination or more targeted queries might be beneficial for performance:


🏁 Script executed:

#!/bin/bash
# Check if Apollo Client has pagination capabilities in the codebase
rg -n "useQuery.*fetchMore" --type ts --type tsx

Length of output: 78


🏁 Script executed:

#!/bin/bash
# Search for Apollo Client pagination usage (fetchMore) across .ts and .tsx files
rg -n "fetchMore" --glob "*.ts*"

Length of output: 32


Consider adding pagination for the GET_MOVIES query
I didn’t find any use of Apollo Client’s fetchMore or other pagination patterns in the codebase, and this deeply nested query (scenes → tracks → songs) could result in large payloads and slow response times. Please review whether you need to:

  • Implement cursor- or offset-based pagination on allMovies (and/or nested fields)
  • Split the query into smaller, more targeted requests

Comprehensive script setup with modern tooling

The scripts are well-configured for development, building, linting, formatting, and type checking using modern tools like Biome and Husky.

The development script uses Turbopack, which is experimental. Please verify it's stable enough for your development workflow:


🌐 Web query:

Is Next.js Turbopack stable for production use?

💡 Result:

Next.js Turbopack Stability for Production Use

Development: Turbopack is Stable

  • The Turbopack bundler is now considered stable for local development in Next.js. The next dev --turbo command reached stability as of late 2024, and has been adopted by over half of Next.js 15 development sessions, delivering significantly faster dev environments and rapid refreshes[1][4][7]. Turbopack supports both the App Router and Pages Router, and can be extended with custom loaders and configuration[2][9].

Production: Turbopack is NOT Yet Stable

  • Production builds using Turbopack, enabled with next build --turbopack, remain in alpha status as of Next.js 15.3 (April 2025)[3][4]. While 99.3% of Next.js’s integration tests for Turbopack builds now pass and build times are measurably faster than with Webpack, several key caveats remain:

    • Alpha Status: Official Next.js documentation and blog posts explicitly state that Turbopack production builds are not recommended for mission-critical applications. It is best suited for preview/staging environments or experimental use, with feedback solicited to help close remaining gaps before stable status[3][4][7].
    • Ecosystem Compatibility: Some third-party tools, plugins, and custom Webpack configurations may not work as expected with Turbopack production builds. Vercel is actively working with the community to ensure compatibility before production release[4][10].
    • Known Issues: Build artifact differences, always-on sourcemap generation (which could expose source code if not configured properly), and disk caching improvements are still being addressed[3][4][8]. Persistent caching and optimizations like tree shaking are in progress.

"Turbopack builds are in alpha. We don’t recommend using them in production for mission-critical applications at this stage. Instead, try them in a preview or staging environment, or run the build locally to observe differences in bundle size and performance."[4]

Summary Table

Environment Turbopack Status Recommendation
Development Stable Use for major projects
Production Build Alpha Preview/staging only; not critical

Should You Use Turbopack for Production in 2025?

  • Safe for Local Development: Yes, Turbopack is stable and delivers major performance improvements for dev workflows[1][2][4].
  • Not Yet Production-Ready: No, production builds are still alpha. Wait for a stable release before using Turbopack for mission-critical deployments[3][4][7][10].

If you want to experiment with Turbopack production builds: Use next build --turbopack in preview or staging, monitor output and compatibility, and track the progress toward stability at resources like areweturboyet.com[4].

Conclusion:
Next.js Turbopack is stable and recommended for development use, but production-ready stability is not yet reached. For now, continue using Webpack or other supported stable solutions for production deployments until Turbopack's production grade is officially marked as stable by the Next.js team.

Comprehensive script setup with modern tooling
The scripts are well-configured for development, building, linting, formatting, and type checking using modern tools like Biome and Husky. Using next dev --turbopack is now considered stable for local development (Turbopack reached stability for next dev in late 2024). Your production build script remains next build (Webpack), which is still the recommended approach until Turbopack’s production mode exits alpha. No changes required.

Latest dependencies with cutting-edge versions

The project uses very recent versions of core libraries (React 19, Next.js 15, Tailwind CSS 4). While this provides access to the latest features, it may introduce stability concerns.


🌐 Web query:

Are React 19 and Next.js 15 stable for production use?

💡 Result:

Stability of React 19 and Next.js 15 for Production

React 19 Stability

React 19 reached stable status in early 2025, introducing notable improvements such as enhanced error boundaries, better performance, new hooks, and support for server components[8][5]. As of Next.js 15.1 (released December 2024), React 19 is considered stable and is fully supported in production environments with the Next.js Pages Router and App Router[10].

The React compiler is currently in Release Candidate (RC) status—intended as near final and safe for tryout in production, with a stable general availability release expected soon[3]. React 19.1, released in March 2025, further enhanced stability and developer experience but highlighted that some ecosystem packages may still be catching up, so verifying your dependencies remains recommended for mission-critical use cases[2].

Next.js 15 Stability

Next.js 15 was announced as officially stable and recommended for production use in October 2024[6]. The release heavily focused on stability, performance improvements (notably with Turbopack Dev), better observability, improved TypeScript support, and full support for React 19[6][10]. Upgrading tools and documentation facilitate smooth migration, and large-scale applications are already running in production on this version[9].

Practical Considerations and Ecosystem Caveats

  • Next.js 15 and React 19 are technically stable for production as of early 2025[6][10].
  • For new projects or applications with minimal third-party dependencies, adopting the latest versions provides access to key performance and developer experience upgrades[7].
  • For existing, complex applications with significant third-party package reliance, some ecosystem dependencies and libraries may not yet fully support React 19 or the Next.js 15 App Router[2][7]. Testing in staging before production rollout is advised, especially if you rely on less common or less actively maintained packages.

"The answer to whether Next.js 15 is production-ready isn't a simple yes or no. It depends heavily on your specific use case and requirements ... If you need rock-solid stability for critical applications or depend on extensive third-party support, it may be best to wait or test thoroughly before upgrading"[7].

Summary Table

Framework Current Status Production Readiness Key Caveat
React 19 Stable (early 2025) Yes, widely supported in production Check dependency compatibility[2][5][10]
Next.js 15 Stable (Oct 2024) Yes, officially stable and recommended for production Ensure third-party ecosystem is compatible[6][7][10]

Conclusion

React 19 and Next.js 15 are officially stable and generally ready for production use, particularly for new projects and teams that prioritize the latest features and performance enhancements. The main caveat is third-party ecosystem support: for complex projects with many dependencies, thorough testing is essential to confirm compatibility before upgrading[2][7][10].

examples/music-licensing-challenge-nextjs/src/utils/getMoviesData.ts (3)

4-7: LGTM! Clean implementation of the API fetch function.

The fetchMoviesData function is well-structured and follows a good pattern for fetching data from an API.


9-15: LGTM! Efficient scene search implementation.

This helper function efficiently flattens the nested movie data structure and searches for a specific scene by ID.


46-64: LGTM! Consistent pattern for scene data retrieval.

The function follows the same pattern as getMoviesData and reuses the findSceneById helper function appropriately.

examples/music-licensing-challenge-nextjs/src/middleware.ts (1)

27-29: LGTM! Appropriate pattern matching for middleware.

The matcher configuration correctly excludes API routes, static assets, and other resource paths from middleware processing, which is an important optimization.

examples/music-licensing-challenge-nextjs/src/types/index.ts (3)

8-12: LGTM! Well-structured Track interface.

The Track interface clearly defines the relationship between tracks and songs.


14-19: LGTM! Clear and concise Scene interface.

The Scene interface adequately represents a movie scene with its properties and relationship to tracks.


21-30: LGTM! Comprehensive MoviesData interface.

The MoviesData interface captures all the necessary properties for a movie entity.

examples/music-licensing-challenge-nextjs/src/components/SceneList/SongItem.tsx (1)

41-48: LGTM! Conditional rendering of edit controls.

The dropdown component is conditionally rendered based on the isEditable prop, which is a good practice for showing/hiding edit controls.

examples/music-licensing-challenge-nextjs/src/components/Dropdown/index.tsx (1)

11-15: LGTM!

The TypeScript interfaces are well defined with clear property types and optional properties correctly marked.

Enhance error feedback for better user experience

The current error page is very minimal. Consider enhancing it with:

  1. More descriptive error information
  2. A way for users to recover (like a "Back to Home" button)
  3. Tailwind styling to match the rest of the application

🛠️ Refactor suggestion

Implement Registration Form and Integration
The RegisterPage component currently renders only a heading and lacks any form fields, client-side validation, or calls to your authentication API. You should add inputs (e.g., email, password), a submit handler that invokes your signUp/registration endpoint, and proper success/error handling.

Example diff to get started:

+import { FormEvent, useState } from 'react';
+import { signUp } from '@/lib/auth';
+
 const RegisterPage: React.FC = () => {
-	return <h1>Register Page</h1>;
+  const [email, setEmail] = useState('');
+  const [password, setPassword] = useState('');
+
+  const handleSubmit = async (e: FormEvent) => {
+    e.preventDefault();
+    await signUp({ email, password });
+    // TODO: handle success (e.g., redirect) and display errors
+  };
+
+  return (
+    <form onSubmit={handleSubmit} className="flex flex-col gap-4 p-6">
+      <h1 className="text-2xl font-bold">Register</h1>
+      <input
+        type="email"
+        value={email}
+        onChange={e => setEmail(e.target.value)}
+        placeholder="Email"
+        className="border p-2 rounded"
+      />
+      <input
+        type="password"
+        value={password}
+        onChange={e => setPassword(e.target.value)}
+        placeholder="Password"
+        className="border p-2 rounded"
+      />
+      <button
+        type="submit"

Improve accessibility of disclosure button

The disclosure button for the mobile menu doesn't have sufficient contrast in its hover state, and the focus state uses focus:outline-hidden which removes focus indicators needed for keyboard navigation.
