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-mvc

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.

ASP.NET Demos

1. You will need Windows. Enable Developer Mode so that the mklink command doesn't require elevation.
   To enable Developer Mode, type "Developer Settings" in a Windows search box and toggle the "Developer Mode" switch in the opened settings dialog.
   Refer to the following articles to learn more: Symlinks, Developer Mode.

2. In the mobile repository, use the Windows console to:

   • 2.1 Run PrepareWorkspace.cmd.
   • 2.2 Run Packer.cmd.

3. Open the mobile/repository.config.json file and set the hg property to the path where your clone of the mobile repository is located. For example:

   {
     "hg": "C:/Work/mobile"
   }

4. Prepare ASP.NET demos for launch and development. Run this command in the mobile/GitHub_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.

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