Installing the JS Generator and Generating a Bundle

Here you’ll learn how to install the Liferay JS Generator and use it to create JavaScript widgets. See the Angular Application, React Application, and Vue Application articles to learn how to use your existing Angular, React, and Vue apps in Liferay DXP.

Follow these steps to create your JavaScript widget:

  1. Install Node.js. Note that Node Package Manager (npm) is installed with this as well. You’ll use npm to install the remaining dependencies and generator, and configure your npm environment.

  2. Install Yeoman for the generator:

    npm install -g yeoman
    
  3. Install the Liferay JS Generator:

    npm install -g generator-liferay-js
    
  4. Run the generator with the command below, select the JavaScript widget you want to create, and answer the prompts that follow.

    yo liferay-js

    npm run deploy
    

Great! Now you know how to install and run the Liferay JS Generator.
