This is the angular tutorial I completed to learn the basics of angular.
Currently, it's got everything the original tutorial has, plus
-
an improved search using native JavaScript features
Instead of making a request every time the searching string is updated, it uses the already received
heroesarray, applies the.filterfunction and returns the matching heroes.This would be problematic if we had a huge array of heroes, because we'd need to fetch them ALL and that's no good. Also, filtering would take way longer than the server's filtering method.
But in this case, the
heroesarray is small and we already have all of them fetched from the start, so why not use that instead? 😎 -
a selection of how many top heroes to show
It's really quite simple - by default, the top
4heroes are displayed. But the user can change that to any value in range [0;heroes.length]The selection also gets saved to the
localStorage, so that it's remembered even after a page refresh -
an automatic build script for github pages
nothing much to it - just a couple of commands crunched together to make the build process seamless

other little bits & peaces
This project was generated with Angular CLI version 7.3.8.
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.
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.
Run ng test to execute the unit tests via Karma.
Run ng e2e to execute the end-to-end tests via Protractor.
To get more help on the Angular CLI use ng help or go check out the Angular CLI README.
