angular-cli: Conditional Imports using an environment variable

Question

Is there a way to conditionally change imports based on an environment variable in angular-cli@1.0.0-beta.16? I\'m trying to do it in a way that doesn\'t require code change

Answer 1

Change your MyService import to:

import { MyService } from './myservice/index';

The surrounding {} will tell the compiler to import a single export from the file. If you want to be able to import like:

import MyService from './myservice/index';

Then you must have a default export in index.ts e.g:

export default MyService; .
