Narmi Design System (NDS)

⚡ Build your own experiences on the Narmi platform!

This design system provides low level utilities and UI components for building custom experiences in combination with the Narmi API.

Getting started

Installation

Narmi Design System is published as a single NPM package.

npm install @narmi/design_system --save

Peer dependencies

Your project must provide the following packages as peer dependencies:

• React (>=16.9, supports Hooks)

Documentation

• 📖 Storybook (latest)
• 🎨 Design Guidelines
• ✏️ Contributing

Usage

Components

Components can be imported from package root:

import { Button, Tooltip } from '@narmi/design_system';

Style Helpers

NDS provides a set of global CSS helper classes to make it easy to tweak styling in your markup with standard Narmi design values. For example:

<div className="padding--all">
  <p className="fontWeight--semibold fontSize--l">
    Semibold large text in a box padded with a standard gutter
  </p>
</div>

For full documentation of available classes, see storybook docs.

Design tokens

All available distributions of design tokens can be found in dist/tokens. All CSS custom properties from design tokens are already included in the base stylesheet, dist/style.css.

To request a new distribution, please file an issue.

Versioning

This project uses Semantic Versioning. Refer to the Changelog for details.

Browser Support

See .browserslistrc for officially supported browsers or run npx browserslist in this project locally to see a full list of targeted browsers.

This project does not support any version of Internet Explorer.

Releases

This project uses semantic-release, configured to use Conventional Commits.

Any time new commits are added to the main branch, the GitHub Action "release" will run semantic-release. The job will parse recent git tags and commit messages to determine the new version number, tag the release, publish to NPM, and update the changelog.

Major releases

All PRs target main unless it contains breaking changes. Any branch containing breaking change commits should target the open major release branch. For example, if NDS is on major version 1, breaking changes should target the branch major/v2.

Branches containing breaking change commits should follow the naming convention breaking/<branch name>.

Commit Guidelines

This project requires structured commit messages in the Conventional Commits format:

<type>(<optional scope>): <short description>

Allowed types are [build, chore, ci, docs, feat, fix, perf, refactor, revert, style, test] . The build, chore, and ci commit types will skip CI and do not trigger a release. Adding a bang (!) to the commit type denotes a breaking change (see docs for more details).

Examples

Making a fix without scope specified:

fix: update global `text-rendering` value

Adding a feature within the scope of the Button component:

feat(Button): add secondary button variant

Breaking change within the Button component scope:

refactor(Button)!: remove variant `disabled`. The `disabled` boolean prop is now used to disable a button.

What is a "Breaking Change?"

Any modification to the design system that requires consumers to update their usage of NDS is considered a breaking change. For example:

• removing or renaming a component
• changing a public className
• interface changes in public methods
• renamed or retyped component props

If you are making a breaking change, please note it in your commit message appropriately.

📸 Working with snapshot tests

The workflow that runs visual snapshot testing is "Chromatic PR Checks"/run_chromatic. All pull requests will block merging until this workflow passes.

Passing conditions for tests:

• No visual changes detected
• Visual changes detected, but approved (indicates an intentional change)
• Visual changes resolved by a code change to match baseline snapshots
• New stories added in the PR are approved in the Chromatic build

Failing conditions for tests:

• Chromatic build has unreviewed diffs
• Chromatic build has denied changes
• New stories haven't been explicitly approved in the Chromatic build

On every push to a PR, this workflow will run snapshots and report results via a comment on the PR. Use the provided links to review diffs in the Chromatic build and/or view the Storybook preview build.

This workflow must be run again to confirm snapshots are passing, triggered by a new push to the PR or by manually running the job.

🔑 Authentication Required: While the Storybook preview is public, you must log into Chromatic with Narmi engineering credentials to view details on the build and approve or deny snapshot changes.

Local Snapshots: When running Storybook locally, you'll see a floating button on the bottom left of the viewport labelled "Run Tests". If you're authenticated with chromatic, this will compare your current stories being served on localhost:6006 against baseline snapshots in Chromatic. Results will appear in the addons panel.

Baselines: Baselines are managed by Chromatic, using the latest approved build, regardless of the PR that triggered it. Once a build is approved, it immediately becomes the new baseline. To keep main as the branch that should be tracked as the baseline in Chromatic, we run a workflow on merges to main that creates an auto-accepted build, designating it as the new baseline.

Manual publishing (Narmi only)

In rare circumstances, you may need to manually publish a version of NDS outside of the normal automated release process.

Publishing a beta version

1. Rebuild NDS (npm run build)
2. Update the version field of package.json to be a beta of the next minor. For example, you would change 2.35.2 to 2.36.0-beta.0. DO NOT COMMIT THIS CHANGE.
3. Publish the package (npm publish --tag beta)
4. In your consuming application, you can point the @narmi/[email protected]

If you need to make additional changes after the beta is published...

1. Rebuild NDS (npm run build)
2. Bump the beta version number in package.json (2.36.0-beta.0 -> 2.36.0-beta.1)
3. Install the new beta version in your consuming application.

Publishing a patch over a previous version

In rare cases, you may need to publish a patch over a previous version (e.g., patching 2.35.2 when the current version is 2.36.0).

Follow the same steps as publishing a beta version, but without the --tag beta flag:

1. Rebuild NDS (npm run build)
2. Update the version field of package.json to the desired patch version (e.g., 2.35.3). DO NOT COMMIT THIS CHANGE.
3. Publish the package (npm publish)

Testing unpublished changes in a consumer

Development of Narmi Design System should be done in isolation within this repo. There are however, some rare circumstances where you may need to test NDS changes against some consuming application.

The best way to approach testing unpublished NDS changes in a consumer is to use beta versions. See Publishing a beta version for instructions.
