For explanation here https://codeburst.io/the-right-way-to-prefetch-data-for-your-angular-components-pages-1e5cce099cee 4 | ## Screenshot 5 | ![](screenshot/resolver.gif) 6 | 7 | ## Dependencies 8 | * [Bootstrap](https://github.com/twbs/bootstrap) : just the css was used, check [.angular-cli.json](.angular-cli.json) **styles** array where it was added to the project 9 | * [ng2-slim-loading-bar](https://github.com/akserg/ng2-slim-loading-bar) : Used for managing our page loader, using the inbuilt service to trigger our loader, check [app.component.ts](src/app/app.component.ts), also the [styles.css](src/styles.css) and don't forget to import it to your [app.module.ts](src/app/app.module.ts), **imports** array 10 | * [ngAlert](https://github.com/theo4u/ngAlert) : Used in showing app-level alert error message, check [app.component.ts](src/app/app.component.ts), also the [styles.css](src/styles.css) and don't forget to import it to your [app.module.ts](src/app/app.module.ts), **imports** array 11 | 12 | ## Development server 13 | 14 | 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. 15 | 16 | ## Code scaffolding 17 | 18 | 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`. 19 | 20 | ## Build 21 | 22 | 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. 23 | 24 | ## Running unit tests 25 | 26 | Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io). 27 | 28 | ## Running end-to-end tests 29 | 30 | Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/). 31 | 32 | ## Further help 33 | 34 | To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md). 35 | -------------------------------------------------------------------------------- /e2e/app.e2e-spec.ts: -------------------------------------------------------------------------------- 1 | import { AppPage } from './app.po';
