This article lists the requirements for generating and running Angular applications in your development environment, and also running Angular applications in your production environment.
For Angular applications development, your development environment should include the following:
Get Node.js from nodejs.org (download the LTS version). After the installation of Node.js, to check your version run the following command in a terminal/console window:
Version has to be v16.13.1 (LTS) or higher
For the environment setup, npm packages will be installed (automatically) using the npm client command line interface, so you must have an npm package manager. Node.js includes it by default.

- Browsers on Chromium engine, like
- Google Chrome
- Microsoft Edge
Note: Internet explorer is not supported.
