Angular 18 New Features

Improved Debugging Tools

1. Route Redirects with Functions

Angular 18 introduces a new feature for managing redirects. Now strings can be replaced with functions to specify the redirect URL within the redirectTo property of the Route object. This feature increases the flexibility in routing and opens up new possibilities.

This function lets you access the object containing information about the URL. The “url” object contains all information about the route, including its data, title, query parameters, routing segment, and more. The function must return a reference to the string or an UrlTree. Do you know about UrlTree? It is a data structure representing a URL. It’s essentially a parsed representation of a URL that Angular’s router uses to navigate within an application.

export const routes: Routes = [
    path: 'page1',
    redirectTo: '/page2',
    pathMatch: 'full'

//redirectTo function
export const routes: Routes = [
    path: 'page1',
    redirectTo: (url) => { 
      return '/page2'; 
    pathMatch: 'full'

The UrlTree encloses information like the URL’s segments, query parameters, and fragments. This process is used in Angular’s routing system for various applications like URL manipulation, navigation, and routing guards. By using UrlTree, Angular ensures consistent and reliable navigation behavior within applications.

2. New RedirectCommand

The new RedirectCommand class in the upcoming release will manage NavigationExtras. This feature will enhance redirection capabilities within Guards and Resolvers. Integrating the RedirectCommand class significantly enhances maintainability and flexibility, simplifying the management of complex navigation patterns in Angular applications.

const route: Route = {
  path: 'page1',
  component: PageComponent,
  canActivate: [
    () => {
      const router: Router = inject(Router);
      const urlTree: UrlTree = router.parseUrl('./page2');
      return new RedirectCommand(urlTree, { skipLocationChange: true });

3. ng-content default content

In this release, you can insert default content into the ng-content tag. In Angular, ng-content is a directive used to create a placeholder in a component's template where content can be dynamically inserted. This newly added feature is a logical extension of the ng-content element. If there’s a tag for content, it follows that default content should be included within the tag itself.

4. Zoneless applications

Angular 18 has introduced improved support for "zoneless" applications. Zoneless applications eliminate the reliance on zone.js for change detection, offering several benefits such as improved performance, reduced complexity, and more explicit control over change detection.

One of the primary objectives of Signals is to enable applications to operate without zone.js. Initially, this would have been achievable solely through Signal Components. However, the landscape has since evolved. Now, it will be possible to achieve this without using Signal Components

5. TypeScript 4.7 Support

Angular 18 has the complete support of TypeScript 4.7. There will be an add-on in the characteristics of it in this release. Below are the enhancements that one can now leverage in Angular 18.

1. Template Literal Types

Now, you can precisely specify template types and catch errors easily and accurately.

2. Improved Readonly Support

It will introduce a more consistent and secure way to use the readonly keyword providing developers with efficiency and security benefits.

3. New Import Types

This will help you in creating a modular and organized code enhancing readability and efficiency.

6. Improved Performance with Ivy

This release will make specific optimizations to the Ivy compiler thereby enhancing the performance of various Angular applications. The optimizations will significantly lead to:

  • Faster startup times
  • Smaller bundle sizes
  • Better overall performance

7. New ng-template API

With the arrival of ng-template API in Angular 18, developers can create and use templates without facing any difficulty. It has eased the process of template application. The following are the advantages of this API:

  • Enhanced Type Safety: You can add more precise type definitions within templates. It helps in catching errors at compile time.
  • Cleaner Code: Encourages more declarative, readable, and maintainable code.
  • Enhanced Reusability: Simplifies the creation of reusable components with well-defined types.

8. Enhanced Forms API

It's now going to be simpler for the users to create and validate forms due to the additions going to happen in the forms API with the release of Angular 18. Now, the users will have more control over the form validation process in the following manner:

  • Better Form State Management: Enhanced methods for managing and tracking the state of forms, including pristine, dirty, touched, and untouched states.
  • Async Validation Improvements: Improved support for asynchronous validators, enabling more efficient handling of async validation logic.
  • Better Support for Dynamic Forms: Improved capabilities for creating and managing dynamic forms that change based on user interaction or other factors.
  • Streamlined API: A more intuitive and streamlined API that simplifies the creation and management of reactive and template-driven forms. It gives you the leisure to define validation rules and manage the validation process

9. Improved Debugging Tools

Now no more headaches with the head-eating bugs. There are some advanced debugging tools introduced in the Angular 18 release. With the help of these, you can efficiently debug and test your Angular applications. You'll get to know in detail the application state with the help of these advanced tools which wasn't possible earlier.

Some of the expected enhancements include:

  • Advanced Performance Profiling
    • Tools to measure application performance, detect bottlenecks, and optimize performance.
    • Profiling of component rendering times and change detection cycles.
  • Source Maps and Debugging
    • Improved support for source maps to facilitate better debugging in development environments.
    • Easier correlation between transpiled code and source code.
  • Dependency Injection (DI) Debugging
    • Tools to trace and visualize dependency injection hierarchies.
    • Enhanced error messages for DI-related issues, helping to resolve injection errors quickly.

10. Improved AOT Compilation

A more impactful AOT Compilation for larger apps will be inculcated in the newer release of Angular. Due to its support for third-party libraries, the apps will no longer require runtime compilation. There's also a possibility of having preloaded modules running in the background. There will be improvements in lazy loading and signal-based inputs.

11. Application Optimization

As a developer, you will want your application to load quickly, take less memory space, be user-friendly, etc. Even for a user, these parameters hold for a good application. Angular 18 is expected to come up with some optimizations in its new release. Let's have a look at some of them.

1. Improved Change Detection with New Reactivity Model

The new model simplifies state management, offering clearer patterns for handling complex application states and interactions. Developers benefit from a more intuitive and streamlined approach to reactive programming, leading to cleaner and more maintainable codebases.

2. Default Hybrid Rendering

Default hybrid rendering leverages both server-side rendering (SSR) and client-side rendering (CSR) by default. This hybrid approach optimizes performance by rendering initial content on the server and then enhancing interactivity on the client, providing a fast and smooth user experience. It positions Angular applications for future scalability and growth.

12. Modernized Unit Test Tooling

The unit testing setup process has been streamlined with simplified configuration options, making it easier for developers to set up and customize their testing environments. Integration with modern testing frameworks such as Jest or Cypress allows developers to leverage the latest features and capabilities for testing Angular applications.

13. Component Accessibility

Angular 18 introduces built-in accessibility features, making it easier for developers to create accessible components out of the box without additional configuration.
