AngularJS has been end of life (EOL) since 2022, and yet more than 20% of large enterprises have not yet migrated to a different framework*. Usually when software becomes end of life, there is a clear successor, but that’s not exactly the case with\u00a0AngularJS<\/a>.\u00a0<\/p>

In this blog, we explore how to choose a JavaScript framework to replace AngularJS, with overviews of the most popular JavaScript frameworks as well as different ways to approach your AngularJS migration.<\/p>

Why Replace AngularJS?<\/h2>

As just mentioned, the main reason to replace AngularJS is because it is end of life. This means no more updates, bug fixes, or security patches are being issued from the community. Staying on EOL software exposes your application(s) to vulnerabilities that can be exploited \u2014 resulting in serious fiscal and\/or reputational damage that puts your business in the headlines for all the wrong reasons.\u00a0<\/p>

While security is the most important consideration here, it’s not the only reason to get off AngularJS. New browser versions and updates to jQuery can also wreak havoc and cause breaking changes and downtime. As an older framework, compatibility is another potential problem. As the web development landscape continues to evolve, there is a good chance AngularJS will not always integrate seamlessly with the latest and greatest tools and libraries.\u00a0<\/p>

Key Considerations for Choosing a JavaScript Framework<\/h2>

In general, assessment in three key areas is important as you evaluate\u00a0AngularJS alternatives<\/a>: scalability, community, and learning curve.<\/p>

Scalability:<\/strong>\u00a0Scalability should be one of your top concerns when selecting your next JavaScript framework. Think about your project’s size and complexity, as well as future plans for growth. You need a framework that can scale as your business scales.\u00a0<\/p>

Community:<\/strong>\u00a0The landscape of JavaScript frameworks has grown over the years, but not every project has been widely adopted or proven stable enough to be viable for enterprise. How established is the community? Can you rely on them for support or guidance if you need it? An active community means there will likely be regular updates, bug fixes, and a robust ecosystem with tools and documentation.\u00a0<\/p>

Learning Curve:<\/strong>\u00a0Before adopting a new framework, it’s a good idea to consider how long it will take to learn and your dev team’s current expertise. Is your team already familiar with the framework’s concepts and syntax? Obviously, choosing a framework that is aligned with your team’s existing skills can speed development.<\/p>

Popular JavaScript Frameworks\u00a0<\/h2>

Let’s take a look at a few of the top JavaScript frameworks for frontend development that could be suitable replacements for AngularJS. We’ll focus on how they compare to AngularJS in terms of architecture, DOM, and data-binding, and highlight some benefits and drawbacks.\u00a0<\/p>

Angular<\/h3>

Angular is written in Typescript, which is a superset of JavaScript, so migrating means committing to coding in Typescript moving forward, which may extend the learning curve. Angular does, however, have interoperability with AngularJS, so an upgrade via ngUpgrade is possible. The architecture of Angular is also different from AngularJS: Angular’s component-based architecture (compared to AngularJS’s model-view-controller, or MVC, architecture) is a better fit for mobile-first development and makes it very scalable, due to reusable modular components that simplify the development of complex applications.\u00a0<\/p>

Pros: Extensive list of libraries supported by the core team, very stable, and continually evolving.<\/span>\u00a0<\/span><\/p><\/div>

Cons: Significant vendor lock-in and extremely difficult to write framework-agnostic parts.<\/span>\u00a0<\/span><\/p><\/div>

ReactJS<\/h3>

ReactJS was developed by Facebook and offers a component-based architecture like Angular. While AngularJS is MVC, ReactJS is just V, or View-based, and can be used to build dynamic user interfaces. The biggest difference between AngularJS and ReactJS is their scope: AngularJS is more broad and feature-rich, whereas ReactJS is more narrow in scope, making it lightweight and flexible. AngularJS also relies on the real DOM, which can slow things down compared to virtual DOM frameworks like ReactJS and VueJS.\u00a0<\/p>

Pros: Highly flexible and popular, with the option to use other JSX alternatives if needed.<\/span>\u00a0<\/span><\/p><\/div>

Cons: Despite established best practices, there is no clear consensus on implementation, requiring strong technical leadership to deploy.<\/span>\u00a0<\/span><\/p><\/div>

VueJS<\/h3>

VueJS is known for its versatility and intuitive syntax, making it easy to learn. Like ReactJS, it is lightweight with a small API footprint and focused on the \u201cview\u201d part of the typical MVC architecture. VueJS supports two-way data binding, similar to AngularJS, but discourages it in favor of one-way data flow, which is more flexible. Many developers find it easy to get started with VueJS, but before migrating, be sure to consider how your AngularJS deployments are using behaviors from the AngularJS ecosystem.<\/p>

Pros: Community-driven framework with excellent developer experience (DX) and a robust ecosystem.<\/span>\u00a0<\/span><\/p><\/div>

Cons: Transition from Vue 2 to Vue 3 demonstrates that community-driven changes can be challenging to manage and maintain, posing future risks.<\/span>\u00a0<\/span><\/p><\/div>

EmberJS<\/h3>

Compared to the lightweight simplicity of ReactJS and VueJS, EmberJS is more “complete” and well-suited to complex, high-traffic mobile or desktop applications. It follows the MVVM (model-view-view-model) architecture, and components cannot be reused. Compared to AngularJS’s modular approach, EmberJS utilizes routers, templates, models, and components. While two-way data binding is preferred according to the documentation, one-way data binding is also supported. EmberJS uses a rendering engine called Glimmer, which behaves similarly to a virtual DOM.\u00a0<\/p>

Pros: Comprehensive, all-in-one framework providing more than necessary to develop single-page applications.<\/span>\u00a0<\/span><\/p><\/div>

Cons: Declining usage makes\u00a0<\/span>EmberJS<\/span>\u00a0less resourceful in terms of available solutions.<\/span>\u00a0<\/span><\/p><\/div>

Planning Your AngularJS Migration\u00a0<\/h2>

Both the choice of framework and migration strategy is likely going to be informed by how you\/your stakeholders prioritize quality, time, and cost. In the ideal-but-unlikely scenario that you have unlimited money and unlimited time, you won’t have to sacrifice at all in terms of quality. However, most teams will have to make decisions based on tight deadlines and budgets.\u00a0<\/p>

Questions to Answer Before Migrating<\/h3>

As with any legacy codebase modernization project, you should start by analyzing things like size, complexity, dependencies, and your dev team’s bandwidth. Answering the following questions is a good starting point:\u00a0<\/p>
