Migrating an AngularJS Project into an Nx Workspace

Nx offers first-class support for Angular and React out-of-the-box. But one of the questions the Nrwl team often hears from our community is how to use AngularJS (Angular 1.x) in Nx. Nx is a great choice for managing an AngularJS to Angular upgrade, or just for consolidating your existing polyrepo approach to AngularJS into a monorepo to make maintenance a little easier.

In this article, you’ll learn how to:

  • Create an Nx workspace for an AngularJS application
  • Migrate an AngularJS application into your Nx workspace
  • Convert an existing build process for use in Nx
  • Use Webpack to build an AngularJS application
  • Run unit and end-to-end tests

For this example, you’ll be migrating the Real World AngularJS application from Thinkster.io. You should clone this repo so you have access to the code before beginning.

There is also a repo that shows a completed example of this guide.

The RealWorld app is a great example of an AngularJS app, but it probably doesn’t have the complexity of your own codebase. As you go along, I’ll include some recommendations on how you might apply this example to your larger, more complex application.

Creating your workspace

To start migrating the Real World app, create an Nx workspace:

npx create-nx-workspace@latest nx-migrate-angularjs --cli=angular

When prompted choose the empty preset. The other presets use certain recommended defaults for the workspace configuration. Because you have existing code with specific requirements for configuration, starting with a blank workspace avoids resetting these defaults. This will give you the ability to customize the workspace for the incoming code.

At the next prompt, you can choose whether to use Nx Cloud or not. By using Nx Cloud, you’ll be able to share the computation cache of operations like build, test or even your own commands with everyone working on the same project. Whether you choose to use it or not, the outcome of the migration won’t be affected and you can always change your choice later.

? What to create in the new workspace empty             [an empty workspace with a layout that works best for building apps]
? Use Nx Cloud? (It's free and doesn't require registration.) Yes [Faster builds, run details, GitHub integration. Learn more at https://nx.app]

Creating your app

Your new workspace won’t have much in it because of the empty preset. You’ll need to generate an application to have some structure created. Add the Angular capability to your workspace:

ng add @nrwl/angular  --unitTestRunner=karma --e2eTestRunner=protractor

For this example, we will use Karma and Protractor, the most common unit test runner and e2e test runner for AngularJS.

Codebases with existing unit and e2e tests should continue to use whatever runner they need. We’ve chosen Karma and Protractor here because it’s the most common. If you’re going to be adding unit testing or e2e as part of this transition and are starting fresh, we recommend starting with Jest and Cypress (the default if no arguments are passed to the above command).

With the Angular capability added, generate your application:

ng generate @nrwl/angular:application --name=realworld

Accept the default options for each prompt:

? Which stylesheet format would you like to use? CSS
? Would you like to configure routing for this application? No

The RealWorld app doesn’t have any styles to actually bundle here. They’re all downloaded from a CDN that all of the RealWorld apps use. If your codebase uses something other than CSS, like Sass or PostCSS, you can choose that here.

Migrating dependencies

Copy the dependencies from the RealWorld app’s package.json to the package.json in your workspace. Split the existing dependencies into dependencies (application libraries) and devDependencies (build and test libraries). Everything related to gulp can go into devDependencies.

Your package.json should now look like this:

Run npm install to install all of your new dependencies.

For your own project, you’ll need to switch to NPM if you’re using another package manager like bower. Learn more about switching away from bower

Migrating application code

This Angular application that you generated has the configuration that you need, but you don’t need any of its application code. You’ll replace that with the RealWorld app code. Delete the contents of apps/realworld/src/app.

Starting in the js folder of the realworld app, copy all of the application code into apps/realworld/src/app. The resulting file tree should look like this:

apps
|____realworld-e2e
|____realworld
| |____src
| | |____app
| | | |____settings
| | | |____home
| | | |____config
| | | |____auth
| | | |____layout
| | | |____components
| | | |____profile
| | | |____article
| | | |____services
| | | |____editor
| | | |____app.js
| | |____assets
| | |____environments
| | |____favicon.ico
| | |____index.html
| | |____main.ts
| | |____polyfills.ts
| | |____styles.css
| | |____test.ts

You most likely have your own AngularJS project written in JavaScript as well. While you’ll continue to use JavaScript through the rest of this example, we strongly recommend switching AngularJS projects to TypeScript, especially if you’re planning an upgrade to Angular.

Modifying index.html and main.ts

Your generated application will also have an index.html provided. However, it’s set up for an Angular application, not an AngularJS application. Replace the contents of apps/realworld/src/index.html with the index.html from the RealWorld app.

Your application also has a main.ts file which is responsible for bootstrapping your app. Again, you don’t need much from this file any more. Replace its contents with:

1import './app/app.js';

And re-name it to main.js. This will import the existing app.js file from the RealWorld app which will bootstrap the app.

Adding existing build and serve processes

If you’re looking at the example repo, the code for this section is available on branch initial-migration. This section is an interim step that continues to use gulp to build and serve the app locally, so we can validate everything works before continuing with the migration. You’ll replace gulp in the next section.

The RealWorld app uses gulp 3.9.1 to build. This version is not supported anymore and doesn’t run on any version of Node greater than 10.*. To build this app using gulp, you need to install an appropriate version of Node and make sure you re-install your dependencies. If this isn’t possible (or you just don’t want to), feel free to skip to the next section. The webpack build process should run in any modern Node version.

The RealWorld app uses gulp to build the application, as well as provide a development server. To verify that the migration has worked, stay with that build process for now.

During migration, you should take a small step and confirm that things work before moving ahead. Stopping and checking to see that your app still builds and functions is essential to a successful migration.

Copy the gulpfile.js over from the RealWorld app and put it in apps/realworld. This is where all configuration files reside for the application. Make some adjustments to this file so that your build artifacts land in a different place. In an Nx workspace, all build artifacts should be sent to an app-specific folder in the dist folder at the root of your workspace. Your gulpfile.js should look like this:

1var gulp = require('gulp');
2var notify = require('gulp-notify');
3var source = require('vinyl-source-stream');
4var browserify = require('browserify');
5var babelify = require('babelify');
6var ngAnnotate = require('browserify-ngannotate');
7var browserSync = require('browser-sync').create();
8var rename = require('gulp-rename');
9var templateCache = require('gulp-angular-templatecache');
10var uglify = require('gulp-uglify');
11var merge = require('merge-stream');
12
13// Where our files are located
14var jsFiles = 'src/app/**/*.js';
15var viewFiles = 'src/app/**/*.html';
16
17var interceptErrors = function (error) {
18  var args = Array.prototype.slice.call(arguments);
19
20  // Send error to notification center with gulp-notify
21  notify
22    .onError({
23      title: 'Compile Error',
24      message: '<%= error.message %>',
25    })
26    .apply(this, args);
27
28  // Keep gulp from hanging on this task
29  this.emit('end');
30};
31
32gulp.task('browserify', ['views'], function () {
33  return (
34    browserify('./src/main.js')
35      .transform(babelify, { presets: ['es2015'] })
36      .transform(ngAnnotate)
37      .bundle()
38      .on('error', interceptErrors)
39      //Pass desired output filename to vinyl-source-stream
40      .pipe(source('main.js'))
41      // Start piping stream to tasks!
42      .pipe(gulp.dest('../../dist/apps/realworld/'))
43  );
44});
45
46gulp.task('html', function () {
47  return gulp
48    .src('src/index.html')
49    .on('error', interceptErrors)
50    .pipe(gulp.dest('../../dist/apps/realworld/'));
51});
52
53gulp.task('views', function () {
54  return gulp
55    .src(viewFiles)
56    .pipe(
57      templateCache({
58        standalone: true,
59      })
60    )
61    .on('error', interceptErrors)
62    .pipe(rename('app.templates.js'))
63    .pipe(gulp.dest('src/app/config'));
64});
65
66// This task is used for building production ready
67// minified JS/CSS files into the dist/ folder
68gulp.task('build', ['html', 'browserify'], function () {
69  var html = gulp
70    .src('../../dist/apps/realworld/index.html')
71    .pipe(gulp.dest('../../dist/apps/realworld/'));
72
73  var js = gulp
74    .src('../../dist/apps/realworld/main.js')
75    .pipe(uglify())
76    .pipe(gulp.dest('../../dist/apps/realworld/'));
77
78  return merge(html, js);
79});
80
81gulp.task('default', ['html', 'browserify'], function () {
82  browserSync.init(['../../dist/apps/realworld/**/**.**'], {
83    server: '../../dist/apps/realworld',
84    port: 4000,
85    notify: false,
86    ui: {
87      port: 4001,
88    },
89  });
90
91  gulp.watch('src/index.html', ['html']);
92  gulp.watch(viewFiles, ['views']);
93  gulp.watch(jsFiles, ['browserify']);
94});

You need to point your build and serve tasks at this gulp build process. Typically, an Angular app is built using the Angular CLI, but the Angular CLI doesn’t know how to build AngularJS projects. All of your tasks are configured in the angular.json file. Find the build and serve tasks and replace them with this code block:

1...
2        "build": {
3          "executor": "@nrwl/workspace:run-commands",
4          "options": {
5            "commands": [
6              {
7                "command": "npx gulp --gulpfile apps/realworld/gulpfile.js build"
8              }
9            ]
10          }
11        },
12        "serve": {
13          "executor": "@nrwl/workspace:run-commands",
14          "options": {
15            "commands": [
16              {
17                "command": "npx gulp --gulpfile apps/realworld/gulpfile.js"
18              }
19            ]
20          }
21        },
22...

This sets up the build and serve commands to use the locally installed version of gulp to run build and serve. To see the RealWorld app working, run:

ng serve realworld

Navigate around the application and see that things work.

Your own project might not be using gulp. If you’re using webpack, you can follow the next section and substitute your own webpack configuration. If you’re using something else like grunt or a home-grown solution, you can follow the same steps here to use it. You’ll use the run-commands executor and substitute in the commands for your project.

Switching to webpack

So far, you’ve mostly gotten already existing code and processes to work. This is the best way to get started with any migration: get existing code to work before you start making changes. This gives you a good, stable base to build on. It also means you having working code now rather than hoping you’ll have working code in the future!

But migrating AngularJS code means we need to switch some of our tools to a more modern tool stack. Specifically, using webpack and babel is going to allow us to take advantage of Nx more easily. Becoming an expert in these build tools is outside the scope of this article, but I’ll address some AngularJS specific concerns. To get started, install these new dependencies:

npm install -D @nrwl/web babel-plugin-angularjs-annotate

Nx already has most of what you need for webpack added as a dependency. @nrwl/web contains the executors we need to use to build and serve the application with webpack and babel-plugin-angularjs-annotate is going to accomplish the same thing that browserify-ngannotate previously did in gulp: add dependency injection annotations.

Start with a webpack.config.js file in your application’s root directory:

1const path = require('path');
2
3module.exports = (config, context) => {
4  return {
5    ...config,
6    module: {
7      strictExportPresence: true,
8      rules: [
9        {
10          test: /\.html$/,
11          use: [{ loader: 'raw-loader' }],
12        },
13        // Load js files through Babel
14        {
15          test: /\.(js|jsx)$/,
16          loader: 'babel-loader',
17          options: {
18            presets: ['@babel/preset-env'],
19            plugins: ['angularjs-annotate'],
20          },
21        },
22      ],
23    },
24  };
25};

This webpack configuration is deliberately simplified for this tutorial. A real production-ready webpack config for your project will be much more involved. See this project for an example.

To use webpack instead of gulp, go back to your angular.json file and modify the build and serve commands again:

1...

3  "executor": "@nrwl/web:build",
4  "options": {
5    "outputPath": "dist/apps/realworld",

50...

You may have noticed a rule for loading HTML in webpack.config.js. You need to modify some of your AngularJS code to load HTML differently. The application previously used the template cache to store all of the component templates in code, rather than download them at run time. This works, but you can do things a little better with webpack.

Rather than assigning templateUrl for your components, you can instead import the HTML and assign it to the template attribute. This is effectively the same as writing your templates in-line, but you still have the benefit of having a separate HTML file. The advantage is that the template is tied to its component, not a global module like the template cache. Loading all templates into the template cache is more performant than individually downloading templates, but it also means your user is downloading every single component’s template as part of start-up. This was fine in AngularJS when you didn’t easily have access to lazy-loading, so you always had a large up-front download cost. As you begin to upgrade to Angular or other modern frontend frameworks, you will gain access to lazy-loading: only loading code when it’s necessary. By making this change now, you set yourself up for success later.

To accomplish this, open config/app.config.js which is the main app component. Modify it like this:

1import authInterceptor from './auth.interceptor';
2import template from '../layout/app-view.html';
3
4function AppConfig(
5  $httpProvider,
6  $stateProvider,
7  $locationProvider,
8  $urlRouterProvider
9) {
10  'ngInject';
11
12  $httpProvider.interceptors.push(authInterceptor);
13
14  /*
15    If you don't want hashbang routing, uncomment this line.
16    Our tutorial will be using hashbang routing though :)
17  */
18  // $locationProvider.html5Mode(true);
19
20  $stateProvider.state('app', {
21    abstract: true,
22    template,
23    resolve: {
24      auth: function (User) {
25        return User.verifyAuth();
26      },
27    },
28  });
29
30  $urlRouterProvider.otherwise('/');
31}
32
33export default AppConfig;

This change loads the HTML code directly and sets it to the template attribute of the component. The HTML rule that you specified in the webpack config will take care of loading the HTML correctly and adding it to the template like this.

Now, go through each component of the application and make this change. To make sure that you’ve really modified every component correctly, delete the template cache file (config/app.templates.js) that gulp generated earlier.

In an example like this, it’s easy enough to make this kind of change by hand. In a larger codebase, doing this manually could be very time-intensive. You’ll want to look into an automated tool to do this for you, such as js-codemod or generators.

We also need to modify the app.js and remove the import of config/app.templates.js. Modify it like this:

1import angular from 'angular';
2
3// Import our app config files
4import constants from './config/app.constants';
5import appConfig from './config/app.config';
6import appRun from './config/app.run';
7import 'angular-ui-router';
8// Import our app functionaity
9import './layout';
10import './components';
11import './home';
12import './profile';
13import './article';
14import './services';
15import './auth';
16import './settings';
17import './editor';
18
19// Create and bootstrap application
20const requires = [
21  'ui.router',
22  'app.layout',
23  'app.components',
24  'app.home',
25  'app.profile',
26  'app.article',
27  'app.services',
28  'app.auth',
29  'app.settings',
30  'app.editor',
31];
32
33// Mount on window for testing
34window.app = angular.module('app', requires);
35
36angular.module('app').constant('AppConstants', constants);
37
38angular.module('app').config(appConfig);
39
40angular.module('app').run(appRun);
41
42angular.bootstrap(document, ['app'], {
43  strictDi: true,
44});

Run the application the same way as before:

ng serve realworld

Unit testing

Unit testing can be an important part of any code migration. If you migrate your code into a new system, and all of your unit tests pass, you have a higher degree of confidence that your application actually works without manually testing. Unfortunately, the RealWorld application doesn’t have any unit tests, but you can add your own.

You need a few dependencies for AngularJS unit testing that Nx doesn’t provide by default:

npm install -D angular-mocks@1.5.11 karma-webpack

Earlier, you configured this app to use Karma as its unit test runner. Nx has provided a Karma config file for you, but you’ll need to modify it to work with AngularJS:

1const webpack = require('./webpack.config');
2const getBaseKarmaConfig = require('../../karma.conf');
3
4module.exports = function (config) {
5  const baseConfig = getBaseKarmaConfig();
6  config.set({
7    ...baseConfig,
8    frameworks: ['jasmine'],
9    plugins: [
10      require('karma-jasmine'),
11      require('karma-chrome-launcher'),
12      require('karma-jasmine-html-reporter'),
13      require('karma-coverage-istanbul-reporter'),
14      require('karma-webpack'),
15    ],
16    // This will be the new entry to webpack
17    // so it should just be a single file
18    files: ['src/test.js'],
19
20    // Preprocess test index and test files using
21    // webpack (will run babel)
22    preprocessors: {
23      'src/test.js': ['webpack'],
24      'src/**/*.spec.js': ['webpack'],
25    },
26
27    // Reference webpack config (single object)
28    // and configure some middleware settings
29    webpack: {
30      ...webpack({}),
31      mode: 'development',
32    },
33    webpackMiddleware: {
34      noInfo: true,
35      stats: 'errors-only',
36    },
37
38    // Typical Karma settings, see docs
39    reporters: ['progress'],
40    port: 9876,
41    colors: true,
42    logLevel: config.LOG_INFO,
43    autoWatch: true,
44    browsers: ['ChromeHeadless'],
45    singleRun: true,
46    concurrency: Infinity,
47  });
48};

Next, rename the existing apps/realworld/src/test.ts to apps/realworld/src/test.js and modify its content to match the following:

1import 'angular';
2import 'angular-mocks';
3import 'angular-ui-router';
4
5// require all test files using special Webpack feature
6// https://webpack.github.io/docs/context.html#require-context
7const testsContext = require.context('./', true, /\.spec$/);
8
9testsContext.keys().forEach(testsContext);

Now add a unit test for the comment component:

1import articleModule from './index';
2
3beforeEach(() => {
4  // Create the module where our functionality can attach to
5  angular.mock.module('ui.router');
6  angular.mock.module(articleModule.name);
7});
8
9let component;
10
11beforeEach(
12  angular.mock.inject(($rootScope, $componentController) => {
13    let User = {
14      current: false,
15    };
16    component = $componentController('comment', { User });
17  })
18);
19
20describe('comment component', () => {
21  it('should be defined', () => {
22    expect(component).toBeDefined();
23  });
24
25  it('should default canModify to false', () => {
26    expect(component.canModify).toEqual(false);
27  });
28});

This unit test does a check to make sure the component compiles and that it sets default permissions correctly.

To run the unit tests:

ng test

You should see green text as your test passes.

Unit tests passing

End to End testing

End to End (or E2E) testing is another important part of migration. The more tests you have to verify your code, the easier it is to confirm that your code works the same way it did before. Again, the realworld application doesn’t have any e2e tests, so you need to add your own.

Nx created realworld-e2e for you when you generated your app. There is an example test already generated in apps/realworld-e2e/src/app.e2e-spec.ts. It has a helper file named app.po.ts. The spec file contains the actual tests, while the po file contains helper functions to retrieve information about the page. The generated test checks to make sure the title of the app is displayed properly, an indication that the app bootstrapped properly in the browser.

You need to modify these files to account for the RealWorld app layout. Make the following modifications:

1//app.e2e-spec.ts
2import { AppPage } from './app.po';
3import { browser, logging } from 'protractor';
4
5describe('workspace-project App', () => {
6  let page: AppPage;
7
8  beforeEach(() => {
9    page = new AppPage();
10  });
11
12  it('should display app title', async () => {
13    await page.navigateTo();
14
15    expect(await page.getTitleText()).toEqual('conduit');
16  });
17
18  afterEach(async () => {
19    // Assert that there are no errors emitted from the browser
20    const logs = await browser.manage().logs().get(logging.Type.BROWSER);
21    expect(logs).not.toContain(
22      jasmine.objectContaining({
23        level: logging.Level.SEVERE,
24      } as logging.Entry)
25    );
26  });
27});
1// app.po.ts
2import { browser, by, element } from 'protractor';
3
4export class AppPage {
5  navigateTo(): Promise<string> {
6    return browser.get(browser.baseUrl) as Promise<string>;
7  }
8
9  getTitleText(): Promise<string> {
10    return element(by.css('h1.logo-font')).getText() as Promise<string>;
11  }
12}

To run e2e tests, use the e2e command:

ng e2e

You should see a browser pop up to run the Protractor tests and then green success text in your console.

Summary

  • Nx workspaces can be customized to support AngularJS projects
  • AngularJS projects can be migrated into an Nx workspace using existing build and serve processes
  • Switching to Webpack can enable your Angular upgrade success later
  • Unit testing and e2e testing can be used on AngularJS projects and can help ensure a successful migration
