?Hey fellow Angular Addict

This is the 30th issue of the Angular Addicts Newsletter, a monthly collection of carefully selected Angular resources that caught my attention. (Here are the 29th, 28th and 27th issues)

?Release announcements

? When (Not) to use Effects in Angular — and what to do instead

In his article, Manfred Steyer explains that effects should be mainly used for rendering tasks that cannot be achieved through data binding, such as logging, painting on a canvas, or custom DOM behavior. If we aim to render data via data binding, to react a signal change, he suggest using computed to synchronously derive values from signals. We can also use RxJs or reactive helpers like rxMethod to react the events behind the signal changes.

? Fascinating Dependency Injection

Armen Vardanyan explores Dependency Injection (DI) in Angular. He shows interesting features like dynamic dependencies with query parameters, sharing a form instance from parent to child and providing global configuration.

? Top 10 Angular Architecture Mistakes You Really Want To Avoid

In his latest blog post, Tomas Trajan collected common mistakes developers make in Angular, like:

• Not thinking about the difference between eager and lazy parts of the app
• Using more than one way to achieve the same
• Focusing on DRY instead of ISOLATION
• Analyzing architecture manually instead of with the help of tooling
• Not being familiar with the two main systems in Angular and the rules by which they behave

? Using Storybook with Angular and Vite

By default, Angular and Storybook uses Webpack to build and serve the Storybook application. In this step-to-step guide, Brandon Roberts guides you through integrating Storybook with Angular using Vite as the development server.

? Caching API Requests in Angular : Better , Faster and Stronger

Koye Mohan Reddy shows how to cache API requests in Angular to improve performance and user experience. He covers implementing caching with HTTP Interceptor, cache invalidation, and memory usage limits.

?‍?About the author

My name is Gergely Szerovay, I worked as a data scientist and full-stack developer for many years, and I have been working as frontend tech lead, focusing on Angular based frontend development. As part of my role, I'm constantly following how Angular and the frontend development scene in general is evolving. To share my knowledge, I started the Angular Addicts monthly newsletter and publication in 2022, so that I can send you the best resources I come across each month. Whether you are a seasoned Angular Addict or a beginner, I got you covered. Let me know if you would like to be included as a writer. Let’s learn Angular together! Subscribe here ?

Angular has evolved very rapidly over the past few years, and in the past year, with the rise of generative AI, our software development workflows have also evolved rapidly. In order to closely follow the evolution of AI-assisted software development, I decided to start building AI tools in public, and publish my progress on AIBoosted.dev. Join my on this learning journey: Subscribe here ?

Follow me on Substack (Angular Addicts), Substack (AIBoosted.dev), Medium, Dev.to, Twitter or LinkedIn to learn more about Angular, and how to build AI apps with AI, Typescript, React and Angular!
