DevExtreme Demos

This repository contains technical DevExtreme demos for Angular, React, Vue, jQuery, ASP.NET MVC, and ASP.NET Core.

To run the demos on your machine, clone this repository, run npm install, and follow the instructions below.

Prepare Demos for Development

To prepare demos for development, you can run a script for all technologies or scripts for JavaScript and ASP.NET individually:

npm run prepare-all

npm run prepare-js

npm run prepare-aspnet

Angular, Vue, and React demos can use bundles instead of separate files from node_modules. With bundles, demos launch faster but become harder to debug. Run the following command to create the bundles and replace the SystemJS configuration:

npm run prepare-bundles

To return to using separate files from node_modules, run npm run prepare-js.

JavaScript Demos

Launch

1. Run the launch script:

   npm run launch-demo
   

2. Navigate to http://localhost:3000/.

You can pass additional parameter to specify port. It can be useful when you need to fast switching beatween one demo on different frameworks:

npm run launch-demo -- 3010

Before Commiting Сhanges

For fix autofixed errors:

npm run fix-lint

Development

1. Run the following script to add a new demo:

   npm run add-demo
   

2. Use the built-in CLI to choose or enter the category, the demo name, and the technology for the new demo.

TS React Infrastructure

1. After you make any changes in React TypeScript sources, run the following command:

npm run convert-to-js split

If you want to run this script on specific folder you can pass it to the arguments

npm run convert-to-js "JSDemos/Demos/Diagram/**/React"

1. To ensure that React JavaScript and TypeScript sources are always in sync, the following GitHub action is used: "Check generated JS demos".

ASP.NET Demos

NOTE: You will need Windows.

1. Clone the devextreme-aspnet repo.

2. Open the repository.config.json file, set the devextreme-aspnet property to the path where your clone of the devextreme-aspnet repository is located, and set the devextreme property to the path DevExtreme repo if you want to use local devextreme dist. For example:

   {
     "devextreme": "C:/Work/DevExtreme",
     "devextreme-aspnet": "C:/Work/devextreme-aspnet"
   }

3. Prepare ASP.NET demos for launch and development. Run this command in the devextreme-demos repository.

   npm run prepare-all
   

   For this, you need .NET Framework 4.5.2 installed on your device. You can download a full Developer Pack here: .NET 4.5.2 Developer Pack Installer.

4. Open the NetCoreDemos/DevExtreme.NETCore.Demos.sln or MVCDemos/DevExtreme.MVC.Demos.sln project in Visual Studio and add or edit demos there.

Launch .NET Demos on Mac OS

NOTE: Install Parallels and Visual Studio in Parallels.

1. Clone the current repo and devextreme-aspnet to a local folder in Parallels Windows.

NOTE: Avoid cloning on the Mac OS file system. The virtual machine treats it like a network drive.

2. Open the repository.config.json file. Set the devextreme-aspnet property to the path of your cloned devextreme-aspnet repository. Set the devextreme property to the DevExtreme repository path if you want to use local DevExtreme distribution. For example:

   {
     "devextreme": "C:/Work/DevExtreme",
     "devextreme-aspnet": "C:/Work/devextreme-aspnet"
   }

3. Prepare ASP.NET demos for launch and development. Run this command in the devextreme-demos repository:

   npm run prepare-all
   

   Ensure you have .NET Framework 4.5.2 installed on your device. You can download the full Developer Pack here: .NET 4.5.2 Developer Pack Installer.

Launch .NET core Demos

NOTE: IIS express supports only .NET 7 on ARM architecture. Therefore, you cannot launch demos using Visual Studio. To run demos on ARM, utilize the Kestrel web server.

1. Execute the following command in the \devextreme-demos\NetCoreDemos\ folder:

dotnet run --urls=http://localhost:5001/

NOTE: --urls can have any url value.

Launch .Net MVC Demos

IIS supports the ARM architecture, so you can launch demos using Visual Studio.

Possible Problems You May Encounter

.NET Core demos do not pick up the latest devextreme sources

Solution:_ Clear local Nuget cache. Remove the Windows:\Users\{username}\.nuget\packages\devextreme.aspnet.core folder.
