AngularJS Application Architecture

AngularJS Application Architecture course by @simpulton #angularjs

  • One challenge when learning AngularJS is that most examples are trivial.
  • This series will demonstrate how to organize and tool your AngularJS application for real work.
  • All projects are different, but with the right set of modular tools you can build a foundation for success.
  • By introducing modules and sub-modules, domain models and state management with ui-router, we will start to establish best practices on how an AngularJS application should not only function, but fit together.

One challenge when learning AngularJS is that most examples are trivial. It is difficult to find materials on learning “real-world” patterns and practices.

The joy of Angular is that you are free to build an application in any form that you wish. MCV, MVVM, MVP, MV*whatever*… You get to decide! Freedom is wonderful.

“But what if I choose poorly?”

Good question.

This series will demonstrate how to organize and tool your AngularJS application for real work. It’s an opinion. A way that has worked on our own projects. Use it as a guide for building the solution that best suits the needs of your projects. All projects are different, but with the right set of modular tools you can build a foundation for success.

Building on the previous series, we are going to refactor Eggly to be modular and scalable. By introducing modules and sub-modules, domain models and state management with ui-router, we will start to establish best practices on how an AngularJS application should not only function, but fit together.

Build a Music Player with Angular & Electron III : Bringing It All Together

  • To achieve this, we need to utilize Angular’s lifecycle hook, which is a lifecycle method called when the component is ready:

    is the only service we are injecting because the is already used by for whatever we need the API service for.

  • This method plucks a random song from the property and plays the plucked song:

    One other thing that the method does is to set the property for which is the UI component that displays the title of the playing song.

  • The method also set’s a property which is dynamically updates the background image of the app with the playing track’s URL.
  • returns the style object based on the image URL:

    The style is set on the template using directive:

    When the component was initialized, we did set up some events for playing time update and song end.

  • The app component template assembles all the UI component while passing them their respective properties and event handlers.

This post is the last part of “Build a Music Player with Angular and Electron.” In the previous post we discussed presentation components…

Creating Contact Manager App with MEAN Stack

  • add = function () { $location.path( ” /contact/add/” ); }; vm.details = function (id) { $location.path( ” /contact/details/” + id); }; vm.
  • then ( function (result) { vm.model = result.data; }); vm.edit = function () { $location.path( ” /contact/edit/” + id); }; vm.cancel = function () { $location.path( ” /” ); }; }; })(angular.module( ” contactManager” ));
  • var express = require( ” express” ); var app = express(); var mongojs = require( ” mongojs” ); var db = mongojs( ” contacts” , [ ” contacts” ]); var bodyParser = require( ” body-parser” ); app.use(express.
  • remove = function (id) { $location.path( ” /contact/remove/” + id); }; }; })(angular.module( ” contactManager” ));

Exploring the Various Decorators in Angular – NetanelBasal

  • QueryList implements an iterable interface it can be used in Angular templates with the ngFor directive.
  • The QueryList is initialized only before the ngAfterViewInit lifecycle hook is available only from this point.
  • Returns the specified elements or directives from the view DOM as QueryList
  • If the injector does not find the dependency, it will throw.
  • The @Host decorator tells DI to look for a dependency in any injector until it reaches the host

QueryList is just a fancy name for an object that stores a list of items. What is special about this object is when the state of the application changes Angular will automatically update the object…

  • get ( Service ) instanceof Service );
  • const { Inject , ReflectiveInjector } = require ( ‘ injection-js ‘ ); class Http {} class Service { static get parameters () { return [[ new Inject (Http)]]; } constructor ( http ) { this .
  • It is extraction of the Angular’s dependency injection which means that it’s feature complete, reliable and well tested.
  • require ( ‘ reflect-metadata ‘ ); var di = require ( ‘ injection-js ‘ ); var Http = di .
  • You can use, for instance, reflect-metadata , or core-js ( core-js/es7/reflect ) .

Angular2 Http Interceptor and Loading Indicator – Longing to know

#blogged: #Angular2 Http Interceptor and Loading Indicator #angularjs

  • In replacing the Http provider, my goal is to create something very similar to my old Request Interceptor.
  • The Http provider has methods for get/post/put and other HTTP verbs, but, for the sake of brevity, I have listed only the general request method that is being implemented.
  • Beyond the basic implementation, we then must tell Angular to use our HttpService rather than the built-in Http provider.
  • It makes a few checks against the pending requests, determines, in the cases of turning off the modal, if it should decrement, and then uses the spinner jquery plugin to display/hide the spinner.
  • When a request is detected, I want to use “spin.js” to display a modal spinner to the user.

Long, long ago, I blogged about Angular 1.x Request Interceptors and how they can be used to display a loading indicator. I really liked that mechanism. You could intercept any request whether you made it or it was made by the framework. Fast-forward to today, and things are significantly different with Angular2.
