To setup your development environment run:
git clone [email protected]:angular/angular
yarn
To run the extension in development mode run:
yarn devtools:devserver
You can also run a standalone version of the demo app with
yarn devtools:devserver:demo-standalone
This would start a development server that you can access on http://localhost:4200. In development, Angular DevTools uses a "development shell." This is different from "chrome shell" in a way, that it runs the user's app in an iframe. DevTools then communicate with the user's app via message passing.
To build the Angular DevTools Chrome extension run:
yarn devtools:build:chrome
You can then install the extension from dist/bin/devtools/projects/shell-browser/src/prodapp
following the guide from here.
You can also build the extension for Firefox with:
yarn devtools:build:firefox
In Firefox, to load the extension, you can go to the about:debugging page, click the "This Firefox" option and then click the Load Temporary Add-on button. You'll have to select the manifest file in dist/bin/devtools/projects/shell-browser/src/prodapp
directly.
