Use ESLint for consistent code quality and Prettier for consistent code formatting

Organize Angular app directory by feature or domain to maintain a modular structure

Divide the app into feature modules for each logical area (e.g., AuthModule, DashboardModule etc)

Follow consistent and descriptive naming conventions for components

Use Shared Modules such as Reusable components, directives and pipes

Implement HTTP interceptors for tasks like adding authorization tokens or handling errors globally

Implement guards such as AuthGuard and RoleGuard to protect routes as needed

Use lazy loading for non-critical modules so it will help to increase the page speed

Only implement state management if necessary, otherwise use service-based state for simplicity

Consider using NgRx, Akita or BehaviorSubject for complex state management

Use Lazy load modules, optimize change detection and optimize images and assets for performance optimization

Enable cache-busting to prevent loading of outdated files

Implement token management for secured endpoints via an HTTP interceptor

Write unit tests for components, services, and pipes using Jasmine and Karma
