import { ScrollSpyModule } from '@thisissoon/angular-scrollspy';
// Provide window object for browser and a suitable replacement
// on other platforms
const getWindow = () => window;
const providers: Provider[] = [{ provide: WindowRef, useFactory: getWindow }];
@NgModule({

Code scaffolding
Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.
Build
Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.
Running unit tests
Run ng test to execute the unit tests via Karma.
Running end-to-end tests
Run ng e2e to execute the end-to-end tests via Protractor.
Making Commits
This repo uses [Commitizen CLI][commitizen] and [Conventional Changelog][conventional-changelog] to create commits and generate changelogs. Instead of running git commit run git cz and follow the prompts. Changelogs will then be generated when creating new releases by running npm run release.
Making Releases
Run npm run release to create a new release. This will use [Standard Version][standard-version] to create a new release. [Standard Version][standard-version] will generate / update the changelog based on commits generated using [Commitizen CLI][commitizen], update the version number following semantic versioning rules and then commit and tag the commit for the release. Simply run git push --follow-tags origin master.
