How to run the app with custom environments? about ionic-environment-variables HOT 2 CLOSED

Sorry I haven't gotten back to you on this one! I just updated the README

If more than dev and prod environments are wanted, there are a few things you will need to do.

1. Change your optimization.config.js and webpack.config.js IONIC_ENV variable to be something else. For example:

'./src/environments/environment' + (process.env.MY_ENV === 'prod' ? '' : '.' + process.env.MY_ENV) + '.ts'

2. Add to your package.json another run script and name it whatever you would like

"serve:testing": "MY_ENV=testing ionic-app-scripts serve"

3. Create your testing file src/environments/environment.testing.ts. This should be whatever you set your MY_ENV to.
4. Finally, run the script by using the name you used for your script in package.json

$ npm run serve:testing
