ng serve host 0.0.0.0

The ng serve command is used to run your Angular application in development mode. This command compiles the application and starts a lightweight development web server that serves the application.

By default, the development server only listens for requests from localhost (127.0.0.1). This means that you won't be able to access the application from other devices on your network.

To allow other devices to access your application, you can specify a different host when running the ng serve command. The 0.0.0.0 host means that the development server will bind to all network interfaces, which allows other devices to access your application.

Here's an example of how to use the ng serve command with the host option:

ng serve --host 0.0.0.0

After running this command, you should see output similar to the following:

** Angular Live Development Server is listening on 0.0.0.0:4200, open your browser on http://localhost:4200/ **

: Compiled successfully.

You can now access your application from any device on your network by navigating to http://<your-ip-address>:4200 in a web browser.

Note that exposing your development server to the network can be a security risk. It's recommended that you only use this configuration for local development and not on a production server.

Conclusion

The ng serve command is a powerful tool that allows you to run your Angular application in development mode. By specifying the host option with a value of 0.0.0.0, you can allow other devices on your network to access your application. However, be sure to use this feature responsibly and never expose your development server on a production server.
