Please refer to its documentation:

• Getting Started
• jQWidgets Angular Documentation

This project is based on Angular CLI.

  npm i -g create-jqwidgets-angular-app 
  create-jqwidgets-angular-app my-app
  cd my-app
  npm start

Then open http://localhost:4200/ to see your app.
When you’re ready to deploy to production, create a minified bundle with npm run build.

Install it once globally:

  npm install -g create-jqwidgets-angular-app

  create-jqwidgets-angular-app my-app
  cd my-app

It will create a directory called my-app inside the current folder.
Inside that directory, it will generate the initial project structure and install the transitive dependencies:

  my-app
  ├── e2e
  ├── node_modules
  ├── src
  ├── angular.json
  ├── browserslist
  ├── karma.conf.js
  ├── package.json
  ├── README.md
  ├── tsconfig.app.json
  ├── tsconfig.json
  ├── tsconfig.spec.json
  ├── tslint.json

Subfolders are not shown in order to keep it short.
Once the installation is done, you can run some commands inside the project folder:

npm start

Builds the app in development mode and starts a web server.
Open http://localhost:4200 to view it in the browser.
The page will reload if you make edits.

npm run build

Builds the app in production mode and stores it in the dist/ directory.

If you’re getting started with jQWidgets and Angular, using create-jqwidgets-angular-app is the easiest way to do this.
Just install, run and you will see an Angular jQWidgets Grid on your page.
Then you can customize the project as much as you want, making something great.
