Learn how to automatically catch all errors in a web application written in Angular and process them accordingly

4 | 5 | 📖 Read more on Medium 6 | 7 | Global Error Handling Cover Image 8 | 9 | ## Development server 10 | 11 | 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. 12 | 13 | ## Code scaffolding 14 | 15 | 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`. 16 | 17 | ## Build 18 | 19 | Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. 20 | 21 | ## Running unit tests 22 | 23 | Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io). 24 | 25 | ## Running end-to-end tests 26 | 27 | Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities. 28 | 29 | ## Further help 30 | 31 | To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page. 32 | -------------------------------------------------------------------------------- /angular.json:
