ngUpgrade & Migration

Note: If you skipped ahead to this section, click here to download a zip of the tutorial at this point.

In this chapter we will be upgrading Socially from Angular1 to Angular2 using Angular's Upgrade Adapter. Why upgrading? Because Angular2 is the next major version of the framework and it will surely be the version we want to go with when building web apps in the future, and we can enjoy many of its benefits like better performance, server-side rendering, more powerful templating, better ecosystem and more. We will also be transforming our JavaScript code into TypeScript inspired by Angular2 team's recommendation.

Switching to TypeScript

First, we will remove the JavaScript compiler, whos belonging Meteor package is pbastowski:angular-babel:

meteor remove pbastowski:angular-babel

Although it is possible to just replace the old JavaScript compiler with a TypeScript compiler, we would like to reserve ng-annotate's compiler as well, since the updating process is gonna be done gradually and our app is gonna be a hybrid of Angular1 and Angular2. Thus, we're gonna install the following package:

meteor add mys:typescript-ng-annotate

Once our app is fully migrated to Angular2, we will replace mys:typescript-ng-annotate with barbatus:typescript, a package which will provide you with a pure TypeScript compiler. TypeScript compiler also relies on declerations, which can be installed via package manager called typings. Further informations about typings and how to install it can be found here. As for now just add the following configuration files:

23.3 Add typings configuration files typings.d.ts

And run the following command which will install the declarations defined in the configuration files we've just added:

$ typings install

By now if will you run the app you will receive warning notifications by the TypeScript compiler. This is caused due to our app not being fully migrated to TypeScript. Once you finish the upgrading process and your app is purely based on Angular2 with proper declarations you shall receive no warnings.

Now that the compiler is ready we will start by switching our entry file into TypeScript:

}
 
if (Meteor.isCordova) {

} else {
  angular.element(document).ready(onReady);
}

Not only we changed the extension of the file, but we also made some adjustments to its content. All Angular1 modules registrations are now manually invoked, due to dependency on the upgrade who's gonna take part further in this tutorial. In addition, the way we import the angular library have changed.

Before:

import angular from 'angular';

After:

import * as angular from 'angular';

Now we gonna go through a component transformation. We will start with the Socially component since it is the root component of our app. We will first change the way we import Angular-related libraries, just like demonstrated above:

import { Meteor } from 'meteor/meteor';
 
import webTemplate from './web.html';
import mobileTemplate from './mobile.html';
import { name as PartiesList } from '../partiesList/partiesList';
import { name as PartyDetails } from '../partyDetails/partyDetails';
import { name as Navigation } from '../navigation/navigation';
import { name as Auth } from '../auth/auth';
 
class Socially {}
 
const name = 'socially';
const template = Meteor.isCordova ? mobileTemplate : webTemplate;
 
// create a module
export default angular.module(name, [
  angularMeteor,
  ngMaterial,
  ngSanitize,
  uiRouter,
  PartiesList,
  PartyDetails,
  Navigation,
  Auth,
  'accounts.ui',
  'ionic'
]).component(name, {
  template,
  controllerAs: name,
  controller: Socially
})
  .config(config)
  .run(run);
 
function config($locationProvider, $urlRouterProvider, $mdIconProvider) {
  'ngInject';
 
  $locationProvider.html5Mode(true);
 
  $urlRouterProvider.otherwise('/parties');
 
  const iconPath =  '/packages/planettraining_material-design-icons/bower_components/material-design-icons/sprites/svg-sprite/';
 
  $mdIconProvider
    .iconSet('social',
      iconPath + 'svg-sprite-social.svg')
    .iconSet('action',
      iconPath + 'svg-sprite-action.svg')
    .iconSet('communication',
      iconPath + 'svg-sprite-communication.svg')
    .iconSet('content',
      iconPath + 'svg-sprite-content.svg')
    .iconSet('toggle',

}
 
function run($rootScope, $state) {
  'ngInject';
 
  $rootScope.$on('$stateChangeError',
    (event, toState, toParams, fromState, fromParams, error) => {
      if (error === 'AUTH_REQUIRED') {
        $state.go('parties');
      }
    }
  );
}

Second, we will specify the exported module as an Angular1 module, since we're dealing with two module systems which come both from Angular1 and Angular2, and we will implement a registration which is called from the entry file like we showed earlier:

import { PartiesListNg1Module } from '../partiesList/partiesList';
import { PartyDetailsNg1Module } from '../partyDetails/partyDetails';
import { NavigationNg1Module } from '../navigation/navigation';
import { AuthNg1Module } from '../auth/auth';
 
class Socially {}
 
...some lines skipped...
const template = Meteor.isCordova ? mobileTemplate : webTemplate;
 
// create a module
export const SociallyNg1Module = angular.module(name, [
  angularMeteor,
  ngMaterial,
  ngSanitize,
  uiRouter,
  PartiesListNg1Module.name,
  PartyDetailsNg1Module.name,
  NavigationNg1Module.name,
  AuthNg1Module.name,
  'accounts.ui',
  'ionic'
]);
 
export function registerSocially() {
  SociallyNg1Module
    .component(name, {
      template,
      controllerAs: name,
      controller: Socially
    })
    .config(config)
    .run(run);
}
 
function config($locationProvider, $urlRouterProvider, $mdIconProvider) {
  'ngInject';

Now we gonna simply switch all the file extensions from .js to .ts and repeat the recent process for each component. This process is a pain so if you don't wanna deal with it just git-checkout the next step of this tutorial.

Once your'e done we shall change the way we import the underscore library otherwise our app might break:

23.8 Import underscore correctly inside Parties Methods imports/api/parties/methods.ts

import * as _ from 'underscore';
import { Meteor } from 'meteor/meteor';

$ npm install --save angular2-meteor-polyfills
$ npm install --save es6-shim
$ npm install --save reflect-metadata
$ npm install --save rxjs
$ npm install --save underscore
$ npm install --save zone.js

angular2-meteor-polyfills will load rxjs, reflect-metadata and zone.js in their chronological order.

Now will start replacing our Angular1 components with Angular2 components, and it would be helpful if we could just do it gradually and not all at once, one component at a time. This is where the Upgrade Adapter kicks in. The adapter will give us the ability to downgrade Angular2 so they can be registered to Angular1 modules, and upgrade Angular1 components so they can be registered to Angular2 modules, thereby we can have a hybrid app. Let's get into business by initializing a new instance of the UpgradeAdapter and passing it as an argument to each module registration:

Note that you have to share the same instance of the adapter otherwise the application might not work as expected. Once we have our adapter we will create an Angular2 module which will represent our Angular2 app's module, and bootstrap our application using the adapter:

Filters to Pipes

Angular1 filters have the same functionality as Angular2 pipes. Further details about the relation between filters pipes can be found in Angular's docs. Filters should be registered to Angular1 modules as normal and pipes should be registered to Angular2 modules, so even though they are almost identical they will have to be duplicated for now.

We will start with the displayName pipe. This is how it should look like, and after we create a pipe it should be declared our app's Angular2 module:

import { DisplayNamePipe } from '../imports/ui/filters/displayNamePipe';

@Pipe({

})
export class DisplayNamePipe {
  transform(user) {
    if (!user) {
      return '';
    }
 
    if (user.profile && user.profile.name) {
      return user.profile.name;
    }
 
    if (user.emails) {
      return user.emails[0].address;
    }
 
    return user;
  }
}

The key concepts of this convertion are:

  • import Pipe decorator.
  • change name to displayName.
  • move a function to be a class with transform method.
  • remove everything related to Angular1.

The same process should be applied for uninvited pipe as well:

export class UninvitedPipe {
  transform(users, party) {
    if (!party) {
      return false;
    }
 
    return users.filter((user) => {
      // if not the owner and not invited
      return user._id !== party.owner && !_.contains(party.invited, user._id);
    });
  }
}

We can't return false inside an ngFor directive so let's replace it with an empty array:

23.14 Return an empty array instead of false imports/ui/filters/uninvitedPipe.ts

export class UninvitedPipe {
  transform(users, party) {
    if (!party) {
      return [];
    }
 
    return users.filter((user) => {

Preparing Angular1 component for migration

We will focus on the PartyUninvited to start with. Let's decorate it with a Component decorator, And like the pipe creation process we will also have to declare a component whenever we create it:
