As a front-end developer, you have probably witnessed the Angular framework’s transformation from AngularJS to high-end, performant client-side interface development. Every new upgrade has made developers’ lives easier. Besides, every new update brings features that make the user journey memorable, such as improved web app scalability and efficiency.

Software developers must understand the history of the Angular version to stay ahead of the competition, bring innovations to existing Angular mobile applications, and build engaging user interfaces. Let’s look at how angular has been transformed from a child to an adult with all the maturity required for a full-packed front-end development tool.

The Evolution of Angular Framework

Angular is an exceptional front-end framework due to its constant and revolutionary approach to developing dynamic and scalable web applications. Though Angular has some loopholes, every new upgrade has ensured it remains flawless. Angular is known for its component-based architecture, typescript, and swift performance, which maintain the efficiency of web apps.

Angular has offered several features so far:

• Improved performance: Ivy rendering engines help offer enhanced performance.
• Flexibility: Makes web apps flexible with standalone components and signals API.
• Better & robust security: Typing and dependencies guarantee no loopholes.
• Enhanced developers’ experience: Using CLI improvements and constant upgrades

Every new version offers new opportunities and sometimes bottlenecks, which are rectified in the immediate next version. Hence, Angular is always the first choice for businesses looking to hire front-end developers and front-end developers to build intuitive user interfaces.

That’s the gist of the Angular version history. Let’s understand how each version eased developers’ lives and helped entrepreneurs reach new audiences.

Angular Version History Timeline and Major Updates

Since its inception, Angular has been a community-driven project, with each version focusing on improvements and adding new features. Every version has challenges, but the Angular community, including you, has always come together to address and fix them in the next release. This collective effort towards innovation and improvement has made Angular a leading and preferred front-end framework.

 

Angular 2: A New Beginning (2016)

AngularJS, the first version, came up with several features, benefits, and disadvantages. Angular 2 is an entire restructuring of its first version of AngularJS. The community introduced component-based architecture and Typescript to maintainability and resolve older version challenges.

Features introduced in the Angular 2

• Component-based architecture replacing scope and controllers
• Making Typescript the primary language
• Better dependency injection

Angular 4: Speed & Productivity (2017)

You must be thinking, where is the Angular 3 version? The makers decided to introduce Angular 4 instead of the 3rd version to comply with the internal package versions. This time, Angular 4 guaranteed faster apps by reducing the bundle sizes. Let’s look at what else they introduced.

Features introduced in the Angular 4

• Boosts rendering with better Ahead-of-time compilations
• Tiny apps bundles
• Improved support for animations & form validations

Angular 5: Focus on Efficiency Improvement (2017)

This version has become one of software developers’ favorites because it modifies features introduced in the previous version and offers a new level of optimization. As a result, software developers have thoroughly enjoyed utilizing Angular 5 for front-end development.

Features introduced in the Angular 5

• Optimizer development for smaller JS bundles
• Prompt loading due to advanced AOT compilation
• Better progressive web app development

Angular 6: CLI & RxJS Overhaul (2018)

With the new update, the Angular community wanted to streamline front-end development, improve the CLI, and enhance modularity. The community also introduced Angular elements so developers can use them as web components in applications that are not built using Angular.

Features introduced in the Angular 6

• Allow software developers to use Angular components in other frameworks
• Allow developers to manage multiple projects under a single project head

Angular 7: User Interface & Experience Improvements (2018)

Angular 7 made it loud and clear before its upgrade that it will focus on performance improvement, helping developers build intuitive user interfaces, and ensuring scalability.

Features introduced in the Angular

• Enable rendering large lists to deliver better performance
• Made it easier to build engaging UI elements
• Improves developer experience with guided configurations

Angular 8: Ivy Rendering Engine (2019)

With Angular 8, the community brought some game-changing improvements, including efficient and faster applications. Ivy renderer, an innovation brought by Angular 8, assures a reduction of bundle size, resulting in app load quickly. Besides, differential loading optimizes browsers’ codes and ensures backward compatibility.

Features introduced in the Angular 8

• Lazy loading feature with dynamic imports
• Smaller & faster apps with Ivy preview
• Builder APIs for enhanced CLI customization

Angular 9: Default Ivy (2020)

With Angular 9, Ivy has become its rendering engine, helping software developers perform better. It reduces the application’s bundle size and keeps it faster to load.

Features introduced in the Angular 9

• Default rendering engine
• Smaller and faster applications
• Better debugging and error messages

Angular 10 to 13: Modifications & Future-Ready (2020-2021)

The update is developer-friendly and focuses on aligning performance with the client’s requirements. With Angular 10, you can expect dependency management and typescript 3.9, while the next update focuses on efficiency and better IMR. Angular 12 aligns with Angular 9, making Ivy the default rendering engine and removing the View engine. Angular 13 ensured streamlining dependency injection and implemented standalone component APIs for improved modularity.

Features introduced in the Angular 10 to 13

• Improved ecosystem
• Rapid development
• View engine removed
• Standalone components preview

Angular 14 to 16: Focused on Developer’s Role (2022-2023)

Angular 14 to 16 brought significant updates, focusing on developer experience and performance. Version 14 introduced standalone components, reducing NgModule complexity, while Angular 15 enhanced stability with better diagnostics and standalone APIs. Angular 16 added reactivity with signals, improving change detection and making apps faster and more intuitive to build.

Features introduced in the Angular 14 to 16

• Typed reactive forms
• Standalone components
• Signals API for better state management
• Esbuild support for rapid development

Angular 17 : Focus on an Unexplored Area (2023)
