Enhance Angular: Implement ariaDescription Property Binding

Hey guys! Let's dive into a neat suggestion to boost Angular's accessibility features. We're talking about making it super easy to use the aria-description attribute, which is a big deal for making web content accessible to everyone. Currently, you gotta jump through a few hoops to get aria-description working in your Angular templates. This proposal aims to streamline that, making your code cleaner and your websites more user-friendly. So, let's explore how we can make Angular even better together!

The Current State of ARIA Attributes in Angular

So, as you may already know, Angular has made some awesome strides in supporting ARIA attributes. Angular's ability to render ARIA property bindings as attributes is a real game-changer. You can now bind properties directly in your templates, like this:

<label>
  Search
  <input type="search" [ariaBusy]="true">
</label>

This is super clean and makes your code more readable. The list of supported attributes is based on the WCAG recommendation "Accessible Rich Internet Applications (WAI-ARIA)" in version 1.2. It's great, but here's the catch: version 1.2 doesn't include some commonly used attributes, such as aria-description. The aria-description is part of version 1.3, which is still a work in progress.

The Problem with aria-description

Because of this, if you want to use aria-description, you're stuck using attribute binding, which looks like this:

<label>
  My Input
  <input type="search" [attr.aria-description]="myDescription()">
</label>

It's not terrible, but it's more verbose and less intuitive than property binding. The goal of this proposal is to reduce the complexity and improve readability to make your coding experience more pleasant.

The Proposal: Simplify aria-description Usage

The main idea here is pretty straightforward: add support for aria-description to be used with property binding. This means you could write your code like this:

<label>
  My Input
  <input type="search"
    [ariaDescription]="myDescription()"
  >
</label>

See how much cleaner that is? It's more consistent with how you handle other ARIA attributes. This change would make your code more readable and less prone to errors. It's a small change with a big impact on the developer experience. It is a win-win situation.

Benefits of this approach

  • Improved Readability: Property binding is generally easier to read and understand. It's immediately clear that you're setting an ARIA attribute. Property binding looks more like how we're used to handling other properties in Angular.
  • Consistency: It keeps the way we handle ARIA attributes consistent across the board. This reduces the cognitive load and makes development smoother.
  • Reduced Errors: Attribute binding can sometimes lead to typos and other errors. Property binding can help prevent these issues, as Angular's template checking can catch some errors earlier.

Expanding ARIA Support in Angular

While adding support for aria-description is a great start, a broader approach could be even better. Considering supporting the updated list of ARIA attributes from the Accessible Rich Internet Applications (WAI-ARIA) version 1.3 could be really useful. This would give developers access to a wider range of ARIA attributes, helping to make websites even more accessible. It's important to keep the codebase up-to-date with the latest accessibility standards.

Broader support considerations

  • Wider accessibility: By aligning with ARIA 1.3, Angular would provide better support for modern accessibility practices.
  • Future-proofing: Staying current with ARIA standards ensures that Angular applications remain accessible as the web evolves.
  • Developer efficiency: Having more ARIA attributes readily available in property binding means developers don't have to spend extra time and effort on workarounds.

Conclusion: A Step Towards Enhanced Accessibility

In conclusion, this proposal is a great opportunity to make Angular even more accessible-friendly. By adding support for the aria-description attribute, we can make our code cleaner, more readable, and easier to maintain. Furthermore, expanding the range of supported ARIA attributes to include those in version 1.3 would be a big win for accessibility. This will contribute to a more inclusive web for everyone. Let's make Angular even better! This is not just about making the code work; it's about making the web a better place. Implementing these changes will significantly improve the developer experience and contribute to the creation of more accessible websites and applications.

Let's get this implemented and continue to improve accessibility in Angular for all of us and the users.
