Angular 20 continues to optimize the Ivy compiler, resulting in faster load times and reduced memory consumption. These improvements are particularly beneficial for applications deployed in Platform-as-a-Service (PaaS) environments.
2. Improved Developer Experience
The Angular CLI has been updated with new commands and options, streamlining the development process. Notably, the ng generate command now supports more templates and configurations, facilitating quicker project scaffolding.
3. Better Integration with PaaS
Angular 20 offers improved integration with popular PaaS providers like Heroku, AWS Elastic Beanstalk, and Google App Engine. The new Angular Deploy tool simplifies the deployment process to these platforms.
4. New Components and Libraries
The release introduces new Material Design components, enhancing UI development. Additionally, the Angular Component Dev Kit (CDK) has been expanded with new tools and utilities, aiding in the creation of custom, performant, and accessible components.
5. Enhanced Security Features
Angular 20 includes built-in protections against common web vulnerabilities like Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF). The framework now supports Content Security Policy (CSP), allowing developers to define and enforce security policies effectively.
6. Improved Testing and Debugging
Testing utilities have been enhanced, with improvements to Angular TestBed and new Protractor integration, making it easier to write and run tests.
