angular best practices and coding standards: a comprehensive tutorial

this tutorial delves into angular best practices and coding standards to help you build maintainable, scalable, and efficient applications. we'll cover various aspects, from project structure and component design to testing and state management.

*i. project structure & organization:*

a well-structured project is crucial for maintainability. angular cli provides a solid foundation, but you can enhance it further.

*feature modules:* organize your application into feature modules based on functionality (e.g., `users`, `products`, `authentication`). this improves modularity and reduces coupling.



*shared module:* create a `shared.module.ts` to house commonly used components, directives, and pipes across multiple modules. this avoids repetitive imports.



*consistent naming conventions:* use a consistent naming convention (e.g., kebab-case for selectors, camelcase for classes).

*ii. component design:*

*single responsibility principle (srp):* each component should have a single, well-defined purpose. avoid creating "god components" that handle too much logic.

*separation of concerns (soc):* separate concerns like presentation (template), logic (component class), and styling (css).

*keep components small & reusable:* aim for small, focused components that can be reused across your application.

*input & output decorators:* use `@input()` to pass data into components and `@output()` to emit events from components.




*iii. services & dependency injection:*

*use services for business logic:* move business logic (data access, api calls, etc.) into services to keep components lean and testable.

*dependency injection:* use angular's dependency injection system to manage dependencies and improve testability.



*iv. rxjs observables & operators:*

*use observables for asynchronous operations:* use rxjs observables to handle asynchronous operat ...
