    npm i @thisissoon/{angular-scrollspy,angular-inviewport} --save


    import { InViewportModule, WindowRef } from '@thisissoon/angular-inviewport';
    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 }];
      imports: [InViewportModule.forRoot(providers), ScrollSpyModule.forRoot()]
    export class AppModule {}


    A working example can be forund in the src folder.


    <ul role="navigation" snScrollSpy id="foo">

    Development server

    Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

    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.


    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 and 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 to create a new release. Standard Version will generate / update the changelog based on commits generated using Commitizen CLI, 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.
