Guidance for optimizing workflow in an 8-step process using ANGULAR.js

I am currently developing an application using Angular.js and I find myself a little confused about utilizing Angular to build it.

Below, you will see a preview of what I have so far - it may not look great, but it functions.

I believe there are more effective ways to accomplish this task, and I would appreciate input from other users considering the following:

The application will: 1) gather inputs across 8 steps 2) based on those inputs, display specific results 3) allow users to navigate to any state at any time

// Setting up an application module
var app = angular.module('website', ['ngSanitize','ngAnimate','ui.router']);

app.config(function($stateProvider, $urlRouterProvider) {

    $urlRouterProvider.otherwise("/home");

    $stateProvider

        .state('home', {
            url: "/home",
            templateUrl: "js/partials/home.html",
            controller: HomeCtrl
        })

        // Additional states for step-by-step process...

});

// Function to calculate new percentage value based on step
function getNewPercentageValue(step, percent){
    var NewPercentage = 0;
    if(percent){
        NewPercentage = percent * step;
    }else{
        $rootScope.values.ActualPercentage = (100/8);
        NewPercentage = $rootScope.values.ActualPercentage * step;
    }
    return NewPercentage;
}

// Controller for Home page
function HomeCtrl($scope, $http, $rootScope, $state) { 
    /* DEFAULT VARIABLES */
    $rootScope.values = {
        ActualPercentageSteps: (100/8),
        ActualPercentage: 0
    };
}

// Controllers for each step in the process...

Answer №1

If you want to define your controllers, you can use app.controller("MyCtrl", function($scope){}) and avoid the need for globally defined functions by referencing them with a quoted string like controller:"MyCtrl".

Additionally, consider moving your common data into a service or factory since both act as singletons and will maintain the data throughout the application's lifespan. Here is an example on Plunker:

The key point to remember is to use angular.copy when replacing the entire object instead of just =, as both controllers reference the same object. Therefore, it is important not to create a new object and point the service to that object to prevent disconnections.

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope, Service) {
  $scope.items = Service.items;

  $scope.someModel = {};

  $scope.addItem = function(item){
    Service.addItem(item);
  }
  $scope.resetItems = function(){
    Service.resetItems();
  }
});

app.controller('AnotherCtrl', function($scope, Service) {
  $scope.items = Service.items;
});

app.service('Service', function($timeout){
  var someService = {
    items:[],
    id:0,
    addItem:function(item){
      someService.items.push({label:item, id:someService.id++});
    },
    resetItems:function(){
      someService.id=0;

      //simulated HTTP call
      $timeout(function(){
        angular.copy([], someService.items);
      })
    }
  };
  return someService;
})
