FOR BABEL 7.X INSTALL V2.X - FOR OLDER V1.X

babel-plugin-transform-ng-autoinject

When writing tests for AngularJS 1.x ease the pain of writing enormous boilerplate like this:

let $rootScope, $httpBackend
beforeEach(inject((_$rootScope_, _$httpBackend_) => {
  $rootScope = _$rootScope_;
  $httpBackend = _$httpBackend_;
}));

With the following syntax:

let $rootScope, $httpBackend
beforeEach(__autoinject($rootScope, $httpBackend));

The plugin simply transforms the __autoinject expression into the former inject(...)

The exact form the plugin outputs the autoinject expression is:

let $rootScope, $httpBackend
beforeEach(inject((_$rootScope_, _$httpBackend_) => {
  ({
    $rootScope,
    $httpBackend
  } = {
    $rootScope: _$rootScope_;
    $httpBackend: _$httpBackend_;
  });
}));
