Top 10 puls Lessons Learned Building Angular Applications

As a speaker at a recent conference, I had the opportunity to present on the topic of "Lessons Learned Building Angular Applications". I believe the insights and experiences shared in this talk would be valuable as a written resource, so I have decided to document them in the form of a blog post. In this post, I will detail the top 50 lessons I have learned while building Angular applications throughout my career. Let's begin.

• Use TypeScript: TypeScript is a super-set of JavaScript that adds optional static typing and other features that can improve the development experience and help catch errors earlier in the development process.
• Use Angular CLI: The Angular CLI is a command-line tool that can generate components, services, and more, and can also test, run, and deploy your app.
• Use a modular architecture: Divide your code into small, reusable modules that can be easily maintained and tested.
• Use reactive forms: Reactive forms offer a way to create and manage forms in a reactive style, using observables to track the form's state and values.
• Use dependency injection: Dependency injection is a way to supply a component with its dependencies, rather than hardcoding them into the component. This can make the component easier to test and reuse.
• Use observables: Observables are a powerful way to manage asynchronous data streams in Angular. Use them to manage data that comes from a server, user input, or other sources.
• Use pipes: Pipes are a way to transform data in an Angular template. Use them to format dates, currency, and other values for display.
• Use async pipe: The async pipe subscribes to an observable or promise and returns the latest value it has emitted. This can help simplify the component class by eliminating the need to unsubscribe from observables.
• Use a centralized state management solution: A centralized state management solution, such as NgRx or Akita, can help manage the state of your app and improve the performance of your app.
• Use AOT compilation: Ahead-of-time (AOT) compilation can improve the performance of your app by compiling your component templates and component logic at build time, rather than at runtime.
• Use Lazy loading: Lazy loading allows you to split your application into smaller chunks that can be loaded on demand, improving the initial load time of your app.
• Use the "on push" change detection strategy: The "on push" change detection strategy can improve the performance of your app by only checking for changes in a component's inputs when the inputs reference a new object.
• Use the Angular router: The Angular router is a powerful tool for managing the navigation of your app. Use it to declaratively specify the routes in your app and handle route changes.
• Use route guards: Route guards are a way to control access to certain routes in your app. Use them to protect routes that should only be accessible to authenticated users or to prevent the user from leaving a form in an unsaved state.
• Use route resolvers: Route resolvers are a way to pre-fetch data required by a component before the component is activated. Use them to improve the performance of your app by reducing the amount of data that needs to be loaded on demand.
• Use multiple modules: Use multiple modules to organize your code and improve the performance of your app by allowing the Angular compiler to statically analyze your app and make optimized decisions about how to build it.
• Use the Angular HTTP client: The Angular HTTP client is a powerful tool for making HTTP requests to a server. Use it to interact with a RESTful API or other back-end service.
• Use the Angular testing utilities: The Angular testing utilities make it easy to write unit tests for your components and services. Use them to ensure that your code is working as expected and to catch bugs early in the development process.
• Use the Angular animation library: The Angular animation library makes it easy
