This is an Angular workspace greated by the official docs of Angular. For example:
ng new my-workspace --createApplication="false"
ng generate application app1
ng generate application app2
ng generate library shared-lib
I do not use the Ionic-CLI because it's not fully supported for Angular multi-app monorepo.
Ionic requires to have a separated package.json and config.xml for each app in your workspace.
But I want to use a single package.json and config.xml. So I setup my own build system with Cordova.
I just included Ionic for the UI and native plugins. And build the app by using the Angular cli ng.
Each app is built to the www folder. And then I simply run Cordova to build my app or run on the device.
See the package.json of the workspace (root).
