Your First #AngularJS App - Part 1: A Comprehensive Tutorial  #AngularJS #MVC #JavaScript

  • Given that we already have a drivers list defined within our scope (hang with me – we’ll get there), and ignoring any CSS (for readability), our HTML might look like: – – body ng-app=”F1FeederApp” table – thead – trth colspan=”4″Drivers Championship Standings/th/tr – /thead – tbody – tr ng-repeat=”driver in…
  • Let’s take a look at the ones we’ve seen already: – – – – The ng-app directive is responsible for bootstrapping your app defining its scope.
  • Let’s add driversController to our function($scope) { – $scope.driversList = [ – { – Driver: { – givenName: ‘Sebastian’, – familyName: ‘Vettel’ – }, – points: 322, – nationality: “German”, – Constructors: [ – {name: “Red Bull”} – ] – }, – { – Driver: { – givenName: ‘Fernando’, -…
  • DOCTYPE html – html – head – titleF-1 Feeder/title – /head – – body ng-app=”F1FeederApp” table – thead – trth colspan=”4″Drivers Championship Standings/th/tr – /thead – tbody – tr ng-repeat=”driver in driversList” – td{{$index + 1}}/td – td – img / – /td – td{{driver.points}}/td – /tr – /tbody -…
  • function($scope, ergastAPIservice) { – $scope.nameFilter = null; – $scope.driversList = []; – – (response) { – //Dig into the responde to get the relevant data – $scope.driversList = }); – }); – – – Now reload the app and check out the result.

If you haven’t tried AngularJS, you’re missing out. In this tutorial, I’ll build an Angular app from start to finish, highlighting examples of its strengths along the way.

What is AngularJS?

AngularJS is a JavaScript MVC framework developed by Google that lets you build well structured, easily testable, and maintainable front-end applications.

And Why Should I Use It?

If you haven’t tried AngularJS yet, you’re missing out. The framework consists of a tightly integrated toolset that will help you build well structured, rich client-side applications in a modular fashion—with less code and more flexibility.

AngularJS extends HTML by providing directives that add functionality to your markup and allow you to create powerful dynamic templates. You can also create your own directives, crafting reusable components that fill your needs and abstracting away all the DOM manipulation logic.

It also implements two-way data binding, connecting your HTML (views) to your JavaScript objects (models) seamlessly. In simple terms, this means that any update on your model will be immediately reflected in your view without the need for any DOM manipulation or event handling (e.g., with jQuery).

Angular provides services on top of XHR that dramatically simplify your code and allow you to abstract API calls into reusable services. With that, you can move your model and business logic to the front-end and build back-end agnostic web apps.

Finally, I love Angular because of its flexibility regarding server communication. Like most…
