How to Build Angular Desktop Apps with Electron

How to Build Angular Desktop Apps with Electron

This post, we'll learn to build cross-platform Desktop app for Angular 7/8 by integrating it with Electron.

Introduction

In this article, In this guide, we will look at how to create an Electron application with the Angular framework using TypeScript.

Electron

Electron is an open-source framework developed and and maintained by GitHub. It is a popular platform for building cross-platform desktop apps for Windows, Linux and macOS with JavaScript, HTML, and CSS.It is essentially a web application that is self-contained as a desktop application.

Installing AngularCLI

Let’s get started by installing Angular CLI, which is the official tool for creating and working with Angular projects. Open a new terminal and run the below command.

npm install -g @angular/cli 

Steps to follow,

Step 1

Create an Angular project setup using the below command or however you want to create it.

ng new projectname

Example,

ng new angularElectron

Step 2

Now, we must install Electron in our Angular app. Open a new terminal and run the below command.

npm install electron --save-dev

Even after installing, Electron will be unaware of the Angular app. So, it should be linked with the Angular app in order to work.

Step 3

Create a script file named as main.js and copy the below code in it. This file is used to link the Angular project with Electron.

const {  
    app,  
    BrowserWindow  
} = require('electron')  
// Keep a global reference of the window object, if you don't, the window will  
// be closed automatically when the JavaScript object is garbage collected.  
let win  
  
function createWindow() {  
    // Create the browser window.  
    win = new BrowserWindow({  
        width: 800,  
        height: 600,  
        webPreferences: {  
            nodeIntegration: true  
        }  
    })  
    // and load the index.html of the app.  
    win.loadFile('dist/angularElectron/index.html')  
    // Open the DevTools.  
    win.webContents.openDevTools()  
    // Emitted when the window is closed.  
    win.on('closed', () => {  
        // Dereference the window object, usually you would store windows  
        // in an array if your app supports multi windows, this is the time  
        // when you should delete the corresponding element.  
        win = null  
    })  
}  
// This method will be called when Electron has finished  
// initialization and is ready to create browser windows.  
// Some APIs can only be used after this event occurs.  
app.on('ready', createWindow)  
// Quit when all windows are closed.  
app.on('window-all-closed', () => {  
    // On macOS it is common for applications and their menu bar  
    // to stay active until the user quits explicitly with Cmd + Q  
    if (process.platform !== 'darwin') {  
        app.quit()  
    }  
})  
app.on('activate', () => {  
    // On macOS it's common to re-create a window in the app when the  
    // dock icon is clicked and there are no other windows open.  
    if (win === null) {  
        createWindow()  
    }  
})  
// In this file you can include the rest of your app's specific main process  
// code. You can also put them in separate files and require them here.  

Change the path of index.html in the script based on your project path.

Refer line#18

Step 4

In Index.html, modify the below line

<base href="/"> to <base href="./">  

Refer line#6

Step 5

In package.json, add the below line to link the newly created script file.

"main":"main.js",

In Scripts, add the below code to run Electron with short code.

"electron":"ng build && electron ."

Refer line#12

Step 6

Now, run the application

npm run electron

On successful execution of the above command, the following Angular UI window pops out.

How to build Native Desktop Apps with Angular and Electron

How to build Native Desktop Apps with Angular and Electron

In this Angular and Electron tutorial, you will learn how to build native desktop apps with Angular and Electron. You might be surprised how easy it is to start building high-quality desktop apps for any platform, or even port your existing Angular app to native desktop platforms. In this tutorial I create a simple timer app, then package it for Windows, MacOS, and Linux.

In this lesson, you will learn how to build native desktop apps with Angular and Electron. You might be surprised how easy it is to start building high-quality desktop apps for any platform, or even port your existing Angular app to native desktop platforms.

This lesson covers the following topics:

  1. Configure Electron 1.7 with Angular 4.x.
  2. Build a simple timer app in Angular.
  3. Package the app for install on Windows 10, macOS, and Linux Ubuntu.

You can obtain the source code for this project on Github.

Initial Setup

Let’s kick things off by building a new angular app from scratch.

Generate the Angular App

Generate a default app with the Angular CLI.

npm install -g @angular/cli
ng new angular-electron
cd angular-electron

Update index.html

The generated root page in Angular points the base href to / - this will cause problems with Electron later on, so let’s update it now. Just add a period in front of the slash in src/index.html.

<base href="./">

Install Electron

You can install Electron in the Angular development environment.

npm install electron --save-dev
Configure Electron

The next step is to configure Electron. There are all sorts of possibilities for customization and we’re just scratching the surface.

main.js

Create a new file named main.js in the root of your project - this is the Electron NodeJS backend. This is the entry point for Electron and defines how our desktop app will react to various events performed via the desktop operating system.

The createWindow function defines the properties of the program window that the user will see. There are many more window options that faciliate additional customization, child windows, modals, etc.

Notice we are loading the window by pointing it to the index.html file in the dist/ folder. Do NOT confuse this with the index file in the src/ folder. At this point, this file does not exist, but it will be created automatically in the next step by running ng build --prod

const { app, BrowserWindow } = require('electron')

let win;

function createWindow () {
  // Create the browser window.
  win = new BrowserWindow({
    width: 600, 
    height: 600,
    backgroundColor: '#ffffff',
    icon: `file://${__dirname}/dist/assets/logo.png`
  })


  win.loadURL(`file://${__dirname}/dist/index.html`)

  //// uncomment below to open the DevTools.
  // win.webContents.openDevTools()

  // Event when the window is closed.
  win.on('closed', function () {
    win = null
  })
}

// Create window on electron intialization
app.on('ready', createWindow)

// Quit when all windows are closed.
app.on('window-all-closed', function () {

  // On macOS specific close process
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', function () {
  // macOS specific close process
  if (win === null) {
    createWindow()
  }
})

That’s it for the Electron setup, all the desktop app magic is happens under the hood.

Custom Build Command

The deployed desktop app will be an Angular AOT build - this happens by default when you run ng build --prod. It’s useful to have a command that will run an AOT production build and start Electron at the same time. This can be easily configured in the package.json file.

package.json

{
  "name": "angular-electron",
  "version": "0.0.0",
  "license": "MIT",
  "main": "main.js", // <-- update here
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "electron": "electron .", // <-- run electron 
    "electron-build": "ng build --prod && electron ." // <-- build app, then run electron 
  },
  // ...omitted
}

Run the command

You can run your angular app as an native desktop app with the following command.

npm run electron-build

At this point, you can run the command (it will take a few seconds) and it will create the dist/ folder and will automatically bring up a window on your operating system with default Angular app.

This setup does not support hot code reloads. Whenever you change some Angular code, you need to rerun the electron-build command. It is possible to setup hot reloads by pointing the window to a remote URL (such as https://localhost:4200) and running ng serve in a separate terminal.

Building the Angular App

Now we need to build an Angular App that’s worthy of being installed. I am building a single page timer that will animate a progress circle, then make a chime sound when complete.

To keep things super simple, I am writing all the code in the app.component

Install Round Progress Bar

To get the progress timer looking good quickly, I installed the angular-svg-round-progressbar package. It gives us a pre-built component that we can animate based on the current state of the timer.

npm install angular-svg-round-progressbar --save

Then add it to the app.module.ts (also add the FormsModule).

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';

import { FormsModule } from '@angular/forms'; // <-- here
import { RoundProgressModule } from 'angular-svg-round-progressbar'; // <-- here

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule, 
    FormsModule, // <-- here
    RoundProgressModule // <-- and here
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.component.ts

The app works by allowing the user to set the number of seconds the timer will run max. The timer progresses by running an RxJS Observable interval every 10th of a second and incrementing the current value.

I also defined several getters help deal with NaN values that can cause errors in the progress circle. They also help keep the HTML logic clean and readable.

import { Component, OnInit } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/interval';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/takeWhile';
import 'rxjs/add/operator/do';


@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {

  max     = 1;
  current = 0;

  /// Start the timer
  start() {
    const interval = Observable.interval(100);
    
        interval
          .takeWhile(_ => !this.isFinished )
          .do(i => this.current += 0.1)
          .subscribe();
  }

   /// finish timer
  finish() {
    this.current = this.max;
  }

  /// reset timer
  reset() {
    this.current = 0;
  }

  /// Getters to prevent NaN errors

  get maxVal() {
    return isNaN(this.max) || this.max < 0.1 ? 0.1 : this.max;
  }

  get currentVal() {
    return isNaN(this.current) || this.current < 0 ? 0 : this.current;
  }

  get isFinished() {
    return this.currentVal >= this.maxVal;
  }

}

app.component.html

In the HTML, we can declare the progress component and display the user interface elements conditionally based on the state of the timer.

<main class="content">
        
    <h1>Electron Timer</h1>

    <div class="progress-wrapper" *ngIf="maxVal">

        <div class="text" *ngIf="!isFinished">
          {{ max - current | number: '1.1-1' }}
        </div>
        
        <div class="text" *ngIf="isFinished">
            ding!
            <audio src="assets/chime.mp3" autoplay></audio>
        </div>
        
        <round-progress
                [max]="max"
                [current]="current"
                [radius]="100"
                [stroke]="25">
        </round-progress>
        
    </div>

    <div class="controls-wrapper">
 
        <label>Seconds</label>
        <input class="input" placeholder="number of seconds" type="text" 
              [(ngModel)]="max"
              (keydown)="reset()">

            
        <button *ngIf="currentVal <= 0" (click)="start()">Start</button>
        <button *ngIf="!isFinished" (click)="finish()">Finish</button>
    </div>


</main>
Packaging for Desktop Operating Systems

Now that we have a decent app ready for desktops, we need to package and distribute it. The electron packager tool will allow to package our code into an executable for desktop platforms - including Windows (win32), MacOS (darwin), and Linux. Keep in mind, there are several other electron packaging tools that might better fit your needs.

npm install electron-packager -g
npm install electron-packager --save-dev

Linux and MacOS developers will need to install WineHQ if they plan on building desktop apps for Windows.

In this example, I am going to build an executable for Windows.

electron-packager . --platform=win32

This will generate a directory /angular-electron-win32-x64/ that contains the executable file.

And why not build one for MacOS while we’re at it.

electron-packager . --platform=darwin

This will generate a directory /angular-electron-darwin-x64/ that contains the app. Zip it and extract it on a mac system and you should be able to run it natively. You will get warnings that it’s from an unknown developer, but this is expected and it’s perfectly safe to open - it’s your own code after all.

The End

That’s it for the basic setup with Electron with Angular.

Node vs Angular : Comparing Two Strong JavaScript Technologies

Just from being a simple client-side scripting language, JavaScript has evolved over the years to turn out to be a powerful programming language. Here Node.js is a cross-platform runtime environment while AngularJS is one of the top JavaScript framework. Angular helps the developers to build web applications which are dynamic in nature using HTML template language and following the MVC design pattern.

An Angular Roadmap — The Past, Present, and Future of Angular

An Angular Roadmap — The Past, Present, and Future of Angular

✅Interested in being an Angular developer in 2019? ... blog post it's most likely that you've written some code in javaScript in the past.

Paleolithic JavaScript — SproutCore

In the beginning, there was SproutCore. It was the first comprehensive JavaScript framework aimed at making it easy to build desktop-quality single-page web apps. It’s not that this wasn’t possible before. When Google released Gmail, it showed the world that web apps really could replace complex desktop applications. Google even open-sourced the Closure toolkit — a set of libraries and an optimizing compiler that it used to build Gmail.

The problem was that Google’s Closure tools weren’t very developer-friendly. They relied heavily on Java, which alienated web developers who were used to working with JavaScript, PHP, Ruby, and Python. Gmail was a great demonstration of what was possible, but developing similar applications still felt out of reach for many.

Some courageous developers managed to string together amazing single page apps using a combination of jQuery, duct tape, and hope. While these apps looked amazing to end-users, for the developers working on them, the apps quickly turned into hulking piles of technical debt that made the dev team dread heading to work in the morning.

As a result, a few enterprising developers began to work on frameworks that would bring Gmail-like apps within easy reach of web developers everywhere. SproutCore was the first of these frameworks to take off. It came with a complete set of widgets that made it possible to build complex web applications without even touching HTML or CSS.

This ended up being great for former desktop developers who had been dragged kicking and screaming onto the web. Several more frameworks popped up with similar goals; GWT and Cappuccino were the most prominent. These frameworks even avoided JavaScript by transpiling other languages into JS. Again, this was great for desktop developers. But it left passionate web developers out in the cold and made them feel as though their hard-won HTML, CSS, and JavaScript skills weren’t valuable.

This left an opening for a framework that truly embraced the web, instead of trying to plaster over it and pretend it was something else. A couple of early frameworks (Backbone and Knockout) appeared, and achieved a moderate amount of success. Ember also showed up around this time. It took SproutCore, stripped it down to its bones, and tried to rebuild it into something truly web-friendly. Ember wanted to be the Six Million Dollar Man of the JavaScript world: rebuilt better, stronger, and faster.

None of these frameworks rocketed to popularity. The world was waiting for something better. In 2010, that something better appeared — it was named Angular.

The Golden Age of Angular

Even before Angular version 1.0 had been released, Angular took the front-end development world by storm. Finally, we had an easy-to-use JavaScript framework that treated HTML as a first-class citizen. Developers and designers could now work together to build amazing single-page applications. This came as a relief to designers, who had been annoyed and offended because older frameworks had treated HTML and CSS as tools for barbarians, tools that no civilized developer should have to touch.

The first thing that seemed magical to developers trying Angular for the first time was two-way data binding. Prior to this, most developers had only seen this kind of data binding in desktop frameworks like WPF and Windows Forms. It was great to be able to bind forms and other UI elements to JavaScript model objects. While two-way data binding could cause performance problems when overused, teams that used it judiciously found that Angular enabled them to create complex front-end applications much more quickly than ever before.

Angular proved to be popular for more than just easy binding of data to HTML elements. Angular directives provided an easy way to create reusable HTML + CSS components. Although other JavaScript frameworks provided this before Angular, Angular was the first one that became extremely popular. Reusable components had long been in-use in server-side frameworks. ASP.NET user controls and partial templates in Rails and Django are but a few examples.

Finally, Angular made dependency injection popular in the front-end development world. Dependency injection had long been popular in enterprise applications, which is perhaps why it hadn’t caught on in the JavaScript world. Front-end developers have long been averse to what they see as needlessly complex enterprise software design patterns. This concern isn’t without merit. Have you ever, in the course of writing an application, said to yourself “What I really need here is a “SimpleBeanFactoryAwareAspectInstanceFactory?”

Dependency injection, though, has proven its worth. And Angular made dependency injection easy to use for an audience that hadn’t used it much in the past. Need an HTTP client? Or perhaps you’d like to do some animation? No problem. Angular had built-in services for those. Just ask for them, and Angular would inject them into your components. No need to instantiate anything yourself.

Or perhaps you wanted to use the browser’s window or location objects without making it impossible to unit test your components outside of a browser? Angular had you covered there too, with its built-in $window and $location services. At runtime, you’d get the browser objects you were expecting. And when running unit tests server-side in Node.js, you could pass mock services into your components to ensure they behaved as expected in various scenarios.

If all of this wasn’t enough, Angular also made it simple to register and inject your own services. For developers who were used to binding all their data to the DOM and hoping for the best, this was awesome. If you were writing a new front-end app that called for APIs that would cost your company a lot of money if overused, you’d probably prefer to be able to write tests ahead of time to ensure that your application doesn’t try to do something like calling the Twilio API 800 million times.

So you’d create a Twilio service that gets injected at runtime. At testing time, you’d create a mock service that records the cost of every API call your application is trying to make. You’d write tests that cover common usage scenarios and ensure that these scenarios don’t result in your company receiving a 7-figure bill. Overall, most developers found that Angular directives combined with dependency injection made it possible to write modular, testable front-end applications using tried-and-true software engineering techniques. Many development teams decided that this resulted in a happy state of affairs, and decided to go all-in on Angular.

The Angular Decline? The Rise of React

While things were mostly great in the world of Angular, it wasn’t all sunshine and lollipops. Developers were starting to run into severe performance problems when they tried to bind too many model objects to too many DOM elements. Some applications slowed to a crawl. Direct calls to $digest and other black-magic sorcery started becoming necessary to achieve acceptable performance. Around the same time, a new challenger appeared: React. At first, React didn’t seem to pose too large a danger to Angular. After all, these React weirdos had gone to the trouble of inventing JSX, which looked a lot like a way to mix markup into your code. Hadn’t we gone to a lot of trouble to invent templating languages for the explicit reason of avoiding mixing markup and code?

As it turned out, React’s approach was pretty popular in the front-end development community. It didn’t rocket to popularity, however. Angular was still dominant, and it looked like it would remain that way. Until that is, Angular’s popularity was given a good kick in the teeth from an unexpected source: the Angular team itself.

The Introduction of Angular 2

Angular 2 was first announced at the ng-europe conference in 2014. The Angular team’s plans came as a shock to the Angular community, to say the least. Reaction from Angular developers was swift and negative… and not without reason. Angular 2 would be getting rid of many familiar concepts from Angular 1, introducing a new, incompatible templating language (and oh, by the way) would also be programmed using an entirely new language.

AngularJS

Although both Angular 1 and Angular 2 were called ‘Angular,’ in reality, they were very different frameworks with a few things in common. To help prevent confusion, the Angular team started referring to the old version of Angular as ‘AngularJS’, and the new version as simply ‘Angular.’ This makes intuitive sense since AngularJS was written in JavaScript, and Angular was not. To keep the distinction between the frameworks clear, I’ll be referring to Angular 1 as AngularJS from this point forward.

As a result of all of this, AngularJS developers lost faith in the framework’s future. They threatened to move to a new framework on future projects, and that is precisely what many of them did. React was the biggest beneficiary of the mass exodus from AngularJS.

Although React didn’t do as much as AngularJS, in a way that was positive. If you’re using a view library that doesn’t try to include everything plus the kitchen sink, it’s a lot more difficult for the developers of that library to pull the rug out from under you in the future. In the beginning, using React was a bit of a pain compared to AngularJS. You had to cobble together a patchwork of libraries just to cover the functionality the AngularJS provided out of the box.

Many teams saw this as a good way to reduce risk, because it was unlikely that the developers of all of those libraries would decide to make backward incompatible breaking changes at the same time, which is essentially what Angular had done.

The Emergence of Vue

To compound AngularJS’ woes, another framework named Vue showed up at about the same time the drama over Angular 2 was occurring. Vue was inspired by AngularJS but aimed to simplify it and get rid of what Vue’s creator saw as unnecessary complexity (so Vue felt very familiar to existing AngularJS developers). Vue provided a safe haven for many AngularJS developers who didn’t want to move over to React.

This doesn’t mean that AngularJS developers were not waiting patiently for Angular 2 to appear. But it’s clear that there was a mass exodus from AngularJS to React and Vue due to the uncertainty caused by the plans for Angular 2.

Rising From the Ashes with Angular 2

Eventually, Angular 2 was released. As expected, it did away with many familiar concepts from AngularJS but kept a few of the best pieces like services and dependency injection. Fortunately for the sanity of developers, Angular uses plain TypeScript and not a fork as originally planned.

To make things more confusing, the Angular team maintained a fork of the new framework that used the Dart programming language instead of TypeScript. Initially, the TypeScript and Dart versions were developed in sync, generated from a single code base. Eventually, the TS and Dart versions of Angular decided to go their separate ways, and Angular Dart now exists on its own.

Even with this confusion, Angular’s popularity began to increase again after the Angular 2 release. It happened slowly. As often occurs in software development, trends shifted. Developers realized that a big, batteries-included framework might actually be useful. After all, when your application grows large enough, you end up actually needing all of those batteries.

Enterprise developers, in particular, began moving back to Angular. This makes sense. Usually, when you start an enterprise web app, you know it is going to be complex. There’s no point in starting with a tiny MVP when you know from the beginning all 87 things your application is going to be expected to do.

Where’s Angular 3?

Although Angular 2 wasn’t perfect, many developers of complex web applications began to realize that the new-and-improved Angular was a good fit for their needs. Fortunately for them, Angular had some exciting improvements in store. More importantly, the Angular team demonstrated that it could consistently publish new versions of the framework with few breaking changes between versions

In a move that seemed odd at the time, the Angular team decided to skip version 3 entirely and move to version 4. This was done for good reason: the team working on Angular’s router package had already pushed ahead and released version 3, while the remainder of Angular was still at version 2.3. They decided to keep all Angular package versions in sync moving forward, and bumping everything up to version 4 for the next release was the easiest way to achieve this.

Angular 4

Angular 4 had some significant changes, including added ahead of time compilation, which resulted in small production JavaScript bundles and shorter application load time. Support for server-side rendering was added, which was a boost for teams that wanted to render their app ahead of time to improve initial load performance. Many other improvements were added throughout the framework, but upgrading apps from Angular 2 to 4 was quick and painless in most cases.

Angular 4.3 and Angular 5

Angular 4.3 added a new HTTP client that was easier to use than the old HTTP service. In Angular 5, the old HTTP service was deprecated and would be dropped in the next release. In spite of this inconvenience, there was relatively little grumbling because the upgrade in most cases was straightforward. Angular 5 also added better internationalization support and further build optimizations.

Angular 6 and 7

Angular 6 and 7 were disappointing to some developers. There were no large changes, but there were many small quality of life improvements, especially to the Angular CLI tooling. The decreasing number of visible changes isn’t an indication that the Angular team has stopped innovating. Instead, it shows that the framework is mature, so the development team is now free to do more work behind the scenes, fixing bugs and improving performance.

The stability of the framework since the release of Angular 2 has drawn some old-school AngularJS developers back into the Angular world. It has also attracted the attention of enterprise development teams. When you’re building enterprise apps that may live for decades it’s ideal to use a framework that gets new releases on a predictable schedule but doesn’t change too rapidly. A developer who had only used Angular 2 could be up and running and contributing to an Angular 7 app within minutes.

The Future of Angular

Angular 8 and Angular Ivy

And that brings us to today. As we’ve seen, Angular has come a long way. It has gone from loved by web developers to being reviled to being admired, although it isn’t yet loved again like it was in its early days.

On the horizon, we have Angular 8. A ton of work has been done in Angular 8 to make it easy to use with the Bazel build system, which is absolutely amazing news for all 3 developers who are using it outside of Google. More excitingly, though, the Angular team is hard at work on a new rendered called Angular Ivy. It’s intended to be a drop-in replacement for the current rendered. For the most part, current apps won’t need to make any changes to use Angular Ivy.

If Angular Ivy is a drop-in replacement, why should developers care? Two important reasons: speed, and bundle size — two very important concerns. For a few years, it seemed like web developers had gone a bit crazy. Teams were shipping JavaScript bundles that were 5MB, 10MB, or even larger, and thinking that there was no problem with this. After all, the applications worked perfectly on the developers’ i7-powered MacBook Pros so they should work fine for everyone, right?

Unfortunately, in the real world, not everyone is running the latest and greatest hardware. Hundreds of millions of people access the internet solely on older Android phones with slightly more processing power than a potato, through internet connections only a little faster than dial-up. For these users, a huge JavaScript bundle takes forever to load, and even longer for their device to parse and run. Even in less extreme cases, there are countless users around the world who aren’t using the latest and greatest hardware. For them, massive JavaScript apps are usable (but painful).

Angular Ivy Expectations

The Angular Ivy renderer will help in several ways:

  1. It is being written with an eye on efficiency, so it will accomplish the same tasks while executing far fewer CPU instructions. This will improve both the battery life and the sanity of users with less-than-powerful devices.
  2. The renderer will be written in a much more modular fashion that the current renderer. This will make it much more amenable to tree-shaking and dead code elimination. As a result, your production JavaScript bundle will include only the code that is needed to run your application, instead of bundling together everything plus the kitchen sink as often happens with the current rendered.
  3. In addition to the bundle-size reduction and improved rendering speed, Angular Ivy has another few quality-of-life enhancements for Angular developers. Rebuild times are significantly faster. So if you’re running your app in development mode and waiting for your changes to appear, you’re now going to be spending a lot less time waiting.
  4. Template-type checking is improved, which means you’ll catch more errors at compile time instead of at runtime. Runtime template bugs are annoying, because they either bite you during testing, or they bite your users when they’re trying to use your app.
  5. The Angular Ivy template compiler will generate code that is human readable, which the current View Engine compiler doesn’t do. This will come in handy when trying to track down tough template bugs.

The net result: smaller apps, faster apps, happier developers, and happier users.

Angular’s Past, Present, and Future

If you’ve been using Angular from its early days all the way until now, then congratulations! While there have been plenty of rough patches, we’ve ended up with a fast, modern framework that is fun to use.

If you were an AngularJS developer but moved on to React, Vue, or something else, I encourage you to give Angular another look. It’s worth your time, even if you decide to stick with what you’re using now.

And if you’ve never used Angular at all, why not give it a shot?

We’ve just been on a whirlwind tour through Angular’s past, present, and future. Without a doubt, it has been quite a ride. Regardless of your Angular background, I hope you’ve enjoyed the tour!
