NOTE: THIS BLOG HAS RECENTLY UNDERGONE UPDATES TO REFLECT THE LATEST ANGULAR VERSIONS. WE WILL CONSISTENTLY UPGRADE THIS ARTICLE IN LINE WITH THE RELEASE OF NEW ANGULAR VERSIONS.

Are you one among those who get blown away by newer angular versions and features since their inception? Well, I’ve been equally enthralled to know the Angular Versions history since AngularJS was first released in 2010. Examining the evolution of Angular releases will help us understand how this framework has progressed over time, how we got here, and what the future holds.

In this ever-changing technological world, knowing Angular’s past can also help us predict future patterns. If you’re an Angular follower, developer, product owner or a Technology Consulting Company, Angular 16 has arrived with a slew of new capabilities that will come in handy while developing web applications of all kinds.

What Exactly Is Angular? 

Angular is an open-source JavaScript front-end web application development framework primarily supported by Google to develop single-page, cross-platform, and performant applications. With increasing popularity and demand for Single Page Applications, Angular versions have quickly picked up the pace and have got adopted all over the world. 

What Is A Single-Page Application?

A single-page application is a website or web application that dynamically interacts with the user by rewriting the current page rather than loading the complete page from the server. A single-page application (SPA) is used by the majority of popular applications, including Facebook, Gmail, Twitter, Google Drive, Netflix, and a plethora of others.

What Is A Cross-Platform Application?

A cross-platform application is a piece of software that can run on a variety of computer architectures and operating systems. Updates are simple and convenient in cross-platform applications as they are internet-based. Here, the app gets automatically updated for all users to ensure that they always have the most up-to-date version, which eventually boosts the overall performance.

The below image shows the angular versions history at one go. The release dates for various Angular versions are as follows:

angular versions history

Here is a bucket list of various Angular version enhancements over time. So let’s explore the Angular Versions History.

AngularJS 1.X

AngularJS 1.X is an open-source front-end web application development framework based on JavaScript with the code for AngularJS written in JavaScript. It is primarily supported by Google and a community of individuals/organizations to overcome a lot of issues that are associated with creating single-page apps.

The main purpose of AngularJS 1.X is to make application development and testing easier by providing a framework for client-side model–view–controller (MVC) and model–view–view model (MVVM) architectures, as well as components commonly found in rich online applications. AngularJS is now in Long Term Support (LTS) mode, with version 1.7.x being the most recent major version release.

Angular 2 

Angular 2 is a revamped version of AngularJS, that is rewritten from scratch by the Angular versions team using TypeScript. The main reason for its reconstruction was to accommodate mobile devices effortlessly. Apart from this, Angular versions 2 enhances the number of languages available by adding extra features and functionalities.

Languages like ES5, ES6, TypeScript, and Dart may be required to write Angular 2 code. Despite being a complete redesign, Angular versions 2 retains many of AngularJS 1.X’s features and practices, such as a streamlined and “native JS” version of dependency injection. In short, developers who already have proficiency with AngularJS 1.X will have a much easier time migrating to Angular versions 2 when compared to other frameworks, like React or Ember. 

Angular 3 

You might have had trouble finding information about the Angular 3 release date. This is because Angular versions 3 was left out mostly due to a version discrepancy between the @angular/core, @angular/compiler, and @angular/router libraries. 

For the Angular 2 version, the core and router look like this.

  1. v2.3.0 of @angular/core
  2. v2.3.0 of the @angular/compiler
  3. v2.3.0 of @angular/compiler-cli
  4. @angular/http v2.3.0 @angular/http v2.3.0 @angular/http v
  5. @angular/router v3.3.0 is now available.

However, the issue faced was with the @angular/router, which was already in a 3.X version. This is due to certain ongoing and significant advances in the router sector, such as route-preload. The release of Angular versions 3 with a roadmap to version 4 is likely to cause a lot of uncertainty. To avoid this uncertainty, developers have decided to skip version 3 and instead release version 4.0.0, which ensures that all major dependencies are up to date.

Web Application Development

Angular 4 

Angular 4 is a web application development framework that is backward compatible with Angular 2.x.x that allows you to create JavaScript apps. As a result, there isn’t much of a difference between Angular 4 and Angular 2. We can, however, state categorically that Angular 4 is not a rebuild of Angular 2.

There are new modifications under the hood that tend to lower the size of generated code for your components by roughly 60% in most circumstances, as well as enhanced bug fix alerts. This resulted in increased compatibility for newer browsers as well as significant framework enhancements. Angular 4 also included a new testing environment that slashed testing time in half and supported JIT (Just-In-Time) compilation to further minimize bundle sizes.

Overall, it was a successful release with very few defects that caused problems for Angular Versions 4 developers. However, migrating from one version to another can be difficult when you’re using certain third-party tools or libraries—that is why it’s crucial to plan ahead for any changes that may arise before updating your project or application.

Some Changes From Angular 2 :

  • Animations are being extracted from @angular/core to reduce the amount of code loaded into our production bundle.
  • You can simply add animation to NgModule by importing BrowserAnimationsModule from @angular/platform-browser/animations.
  • Renderer 2 is used instead of Renderer from the same ‘@angular/core’.
  • *ngIf/then:You may now utilize the else clause as well.
  • In Angular 4, there is no need to create a pattern for email validation.
  • Compatibility with TypeScript 2.1 and 2.2:
  • We can use typescript 2.1 or above; previously, only typescript 1.8 was supported.

Angular 5

Angular 5 is a significant milestone in its evolution because it marked a major shift in how they were positioning its framework. In its early stages, it was primarily touted as a mobile app platform that could be used to construct complex single-page applications. However, Angular 5 has shifted its focus to include desktop web apps as well. It is made up of various parts that form a tree structure with parent and child elements. This release includes a lot of new features and enhancements, including dependency injection, end-to-end tooling, and a decelerative template. 

By default, production builds that were made with the Angular CLI now use the build optimizer. New features were introduced such as DOM and Angular Universal State Transfer API support, enhancements to the Compiler, pipes for Internationalized Numbers, Dates, and Currency. Angular forms have been updated for Blur / Submit and also provide RxJS 5.5 support.

Difference between Angular 4 & Angular 5

Angular 6 

Angular 6 comes with two new angular CLI commands: ng update and ng add. It’s a framework for creating HTML, JavaScript, and TypeScript web applications. To be more specific, Angular 1.X to Angular 6 provides built-in functionality for HTTP services, animation, and materials which in turn provide features of auto-complete, toolbar, menus, navigation, etc. The Angular CLI is the simplest and quickest way to get an Angular 6 app up and running (Command Line Interface).

The following are some additional recent updates:

  • Component Development Kit for Angular Elements (CDK)
  • Starter Components for Angular Materials
  • Workspaces for CLI
  • Tree Shakable Providers
  • Enhancements to Performance
  • RxJS v6

Angular 7 

Angular 7 is a JavaScript framework that makes you create single-page applications (SPA). By the way, this is a popular front-end development framework that is updated regularly by Google’s Angular team. Angular 7 is now available with speed enhancements and new features such as CLI Prompts, Virtual Scrolling, and Drag & Drop. Apart from this. some of the important characteristics of Angular 7, Angular CLI 7, and Material 7 are as follows: CLI Prompts – When using simple commands like ng new or ng add @angular/material, the CLI will now prompt users to explore built-in capabilities such as routing and SCSS support. CLI Prompts and Budgets should be included in Schematics, as well as support for Content Projection in Angular Elements. 

Angular has greater flexibility in providing flawless web app development services for businesses of varying magnitude. In essence, Calibraint as a web application development company caters to all the individual needs of every customer to help each organization reach its full potential.

Angular 8 

Angular 8 is a client-side TypeScript-based framework that is used for dynamic web application development. In fact, it is extremely similar to earlier versions, of the fact that it has a long list of features. Differential loading by default – A procedure in which the browser decides whether to load current or legacy JavaScript based on its own capabilities, Imports for Route Configurations that are Dynamic, Builder APIs in CLI, APIs for workspaces in the CLI, Web Worker Support, and so on. The initial project created with ng new in Angular CLI 8.3.0 includes a revised user interface and ng Deployment.

The opt-in preview for Angular Ivy contains: 

  • Faster rebuild time.
  • Improved payload size. 
  • Improved template type checking.
  • Backward compatibility. 
  • Code that gets generated is easier to read and debug at runtime. 

Angular 9 

By default, each and every application in version 9 uses the Ivy compiler and runtime, and  has the following benefits:

  1. Bundle Size Reduction
  1. Faster test completion
  1. Improved Debugging
  1. Enhanced class and style binding in CSS
  1. Improved type checking
  1. Reduced build errors
  1. Default AOTs (Angular ahead-of-time).
  1. Enhanced Internationalization

The new Angular Material Component included

  • Component of the YouTube player
  • Component for Google Maps

Angular can support TypeScript 3.6 and 3.7 with ease. The underlying foundation of the entire framework has changed in Angular 9. The IVY renderer will be used as the default compiler in all applications. Smaller apps benefit the most from IVY’s tree shaking capability because the angular components interactions methods require less code. One of Angular 9’s main goals is to make applications smaller for a better user experience. The team will most likely focus on developing components in the future, therefore there will be no need for a big API change.

Difference Between Angular 8 & Angular 9

Angular 10

It may seem surprising that Angular pushed another major release just 4 months after the Ivy release. Some of the features that are worth mentioning are warnings about CommonJS imports, optional stricter settings, TypeScript 3.9, TSLib updated to v2.0, TSLint updated to v6 and a new default browser configuration. Apart from these features, there have been a number of bug fixes too. Some of them include avoiding undefined expressions in a holey array, and core avoiding a migration error when a nonexistent symbol is imported. Another bug correction ensures proper identification of modules affected by overrides in TestBed.

If we check the angular versions history when you use a dependency that is packed with CommonJS, you would obviously get results in the form of larger and slower applications. With the introduction of Angular 10, when you use any of these bundles, it will automatically give you a warning message. As a result, the ECMAScript module (ESM) bundle will be a good choice for your next project.

latest version of angular

Angular 11

The key features of Angular 11 are improved router efficiency, automated font inlining, and stricter types. Aside from that, Angular 11 includes the default Automatic font inlining feature, which will be enabled for applications that have already been upgraded.

Popular bug fixes include: 

  1. RouterLink: if defined in a component with an empty path, the relative link is wrong.
  2. StatusChanges for FormGroup and FormControl are not emitted when they are created.
  3. i18n: The use of translation strings outside of templates.

Features released in Angular 11 are: 

  • Automatic font inlining: Angular CLI will download and inline fonts that are utilized and linked in the application during compile time. As a result, the program will run quicker.
  • Improved construction and service
  • Logging and Reporting
  • Updated Ivy-based language service preview Updated Hot Module Replacement (HMR) Support.
  • Use ng serve —hmr for faster builds. 
  • Webpack 5 support is experimental.

Deprecation

  • TSLint has been deprecated by the project’s designers, who encourage switching to ESLint. As a result, TSLint and Codelyzer have been deprecated in version 11.
  • Support for Internet Explorer 9/IE10 and Internet Explorer Mobile has been discontinued.

Angular 12

The goal of Angular 12 is to use “Ivy Everywhere.” This version compared to the angular versions history unlocks a lot of potential for the platform with the move to Ivy, its overall compilation, and rendering pipeline. Important features released in Angular 12 include pleasant workarounds for providing info to HTTP interceptors, inline support @Component decorator’s styles property contains Sass, tailwind CSS support to utilize Tailwind CSS, simply install the tailwinds package and add tailwind.config.js. By default, strict mode is turned on and the Ivy-based Language Service is transitioning from opt-into a default setting. Also, webpack 5 production-ready support is now available, and Internet Explorer 11 support has been phased out.

Along with the above-stated features, Angular 12 brings massive improvements in performance, compilers, language service, form validation, styling, nullish coalescing, legacy i18n message IDs, and many more. The deprecation of the view engine and the addition of the Ivy ecosystem is one of the major enhancements considered in the Angular version 12. In addition to the previously mentioned features, Angular 12 offers many bug fixes for the browser, kernel, language function, and router. The Angular 12.1 version now includes APIs for selecting proper test teardown behavior, as well as compiler improvements for unterminated interpolation and view restoration.

Angular 13

Angular 13 is the most recent version of the TypeScript-based Angular web application development frameworks. It comes out with some exciting new features for Angular developers. The traditional View Engine, on the other hand, is no longer supported by Angular 13. Also, Angular will no longer assist Internet Explorer 11. Angular version 13 codebases that rely on View Engine have higher maintenance costs and are more complex. Now, with Angular 13, creating dynamic components is easy.

Previously we had to write so much code for creating a dynamic component and now it is a hassle-free experience. The new API eliminates the requirement to introduce a ComponentFactoryResolver into the function Object() {[native code]}. Ivy gives you the option of using ViewContainerRef.createComponent to instantiate the component without having to create a factory.

Angular now supports the use of persistent build-cache by default for new v13 projects, resulting in a 68% boost in build speed. For new apps, RxJS 7.4 is now the default. Dropping IE 11 is a positive factor because it results in smaller bundle size and faster app loading time. In addition to that, Angular can now use modern browser features like CSS variables and web animations via native web APIs. TypeScript 4.4 support is now available in the Angular 13 version. As a result, versions before TypeScript 4.4.2 are no longer supported in the core.
