noel balaban gitpod.io provides a Visual Studio Code environment in the browser. So If the project works on your local development environment then it will also work on gitpod.io.

To run the angular project you need to have @angular/cli installed globally so make sure you install it when the command prompt opens in gitpod.io by following the below steps

1. npm install -g @angular/cli
2. npm install
3. ng serve

Then expose the port 4200 by clicking on the expose the port to the public when the popup opens and then click on “open browser” option in the popup displayed.

And you will see the project live. Let me know if that helps.
