Angular is a popular tool that web developers use to build dynamic and complex websites and applications. With each new version, Angular introduces updates that make creating websites easier and better. In June 2022, Angular released its 14th version, which brought exciting changes for developers. Angular 14 includes several important updates. Each is part of the open-source application’s effort to ensure every developer can build websites efficiently while ensuring they work well for everyone.
1. Standalone Components
Standalone components are a major update in Angular 14, working to streamline development. Traditionally, Angular relied heavily on NgModules, which grouped components, directives and pipes. This sometimes made projects more complex than necessary. With Angular 14, you can now build and declare components more directly and simply.
Standalone components reduce the boilerplate code — a common set of code developers need to repeat in multiple places in their projects. By cutting down on this, your projects are cleaner and easier to manage.
This update also enhances project modularity. Reusing components across different parts of an application or even across different projects is easier. This is a huge plus for teams working simultaneously on large applications or multiple projects.
2. Typed Forms
Angular 14 has introduced typed forms, enhancing how developers manage and validate data in forms. This feature brings stronger typing to Angular’s Reactive Forms, allowing for more precise type-checking during development. Typed forms aim to minimize errors and improve form data management by ensuring the data matches expected types.
Forms are essential for collecting user input — effectively managing this input is crucial for a good user experience. While developers could use types with forms before, it wasn’t as integrated or straightforward. With the new update, developers can define the form data structure using TypeScript interfaces or classes.
3. Extended Developer Diagnostics
Another highlight of Angular 14 is the extended developer diagnostics. This feature makes the development process smoother and more intuitive. Angular 14 aims to assist developers by providing more detailed error messages and suggestions. Therefore, you can get a clearer idea of where the issue is and how you can fix it.
This feature works by analyzing the code and identifying patterns or mistakes that frequently lead to bugs. When it detects such a pattern, Angular provides a diagnostic message explaining the problem and potential solutions. As such, you reduce the time spent debugging and searching for solutions to cryptic errors.
4. Strictly Typed Reactive Forms
Strictly typed reactive forms greatly enhance form handling and validation within the framework. This feature builds upon the strengths of Angular’s reactive forms by enforcing strict type checks, reducing the likelihood of runtime errors. Strict typing ensures the form data adheres to a defined structure, offering a more error-resistant development process.
This update allows developers to define the form model using TypeScript interfaces or classes. As such, you get clear documentation of the form structure and ensure you catch any discrepancies. This way, you can identify and correct issues much earlier in the development cycle and reduce the risk of bugs.
Beyond error reduction, it also enhances code readability and maintainability. With a defined structure, it’s easier to understand the form’s data flow and how it’s processed.
5. CLI and Build Optimizations
The Angular CLI (Command Line Interface) and the build optimization process focus on improving workflow efficiency and performance. These enhancements provide a smoother, much faster experience for developers working on Angular projects.
CLI Improvements
The Angular CLI is an essential tool for Angular developers. It offers various commands to create, develop, test and deploy Angular applications. With Angular 14, the CLI update streamlines various tasks and improves usability. These updates include more intuitive commands, better error handling and enhanced feedback mechanisms. Such improvements make initiating and managing Angular projects easier, reducing the learning curve and increasing productivity.
Build Optimizations
Angular 14 also focuses on optimizing the build and compilation process. The goal is to reduce build times and improve the performance of Angular applications. These optimizations include improvements to the Angular compiler, which now better leverages incremental builds. Incremental builds allow the compiler to only recompile parts of the application that have changed rather than rebuilding the entire application. This speeds up the development cycle as a result.
Moreover, Angular 14 offers more efficient bundling strategies and tree-shaking capabilities. Tree-shaking is a process that removes unused code from the final bundle, reducing the application’s size and load times. By optimizing the bundling process, Angular ensures the applications are faster to develop and use, making 74% of users likely to return to your app.
6. Improvements in Accessibility
A key area of focus in Angular 14’s accessibility improvements is within Angular Material. Angular Material components were updated to include better support for screen readers and keyboard navigation, among other accessibility enhancements. These updates make it easier for developers to build applications compliant with WCAG (Web Content Accessibility Guidelines) and other accessibility standards.
For instance, updates to components like buttons, forms and navigational elements now include improved ARIA (Accessible Rich Internet Applications) attributes. These help screen readers interpret and interact with web content more effectively. Enhanced focus management and keyboard patterns also ensure users can navigate Angular applications using a keyboard alone.
With Angular 14, there’s also an increased emphasis on accessibility testing and tooling. The framework encourages using automated tools and testing suites that help identify and fix accessibility issues. As such, Angular developers can adhere to accessibility best practices more consistently.
7. Optional Injectors
Developers now have access to the enhancement of the framework’s DI (dependency injection) system. DI is a core feature of Angular that allows developers to define how and where to provide instances of classes that components may need. It simplifies the management of service dependencies and promotes a modular and testable code structure.
Optional injectors allow developers to specify alternative injectors to provide dependencies rather than relying on Angular’s root injector. This enables more dynamic and context-specific dependency resolution strategies. For instance, developers can easily switch between service implementations based on runtime conditions. This allows you to enhance the application’s modularity and adaptability.
Innovating Web Development With Angular 14
Angular 14 offers several opportunities for developers, from simplifying workflows and enhancing application performance to broadening accessibility. This version can improve your overall experience while ensuring your work is maintainable and future-proof. Consider updating to Angular 14 so you can look forward to an easier web development process from here on out.
