What is Angular file & folder structure ?

In Angular, organizing your project's folder structure is essential for maintaining a clean and manageable codebase. A well-structured folder layout can make it easier to navigate, collaborate, and scale your application. Here's an explanation of a typical folder structure for an Angular application:

src: This is the root folder for your Angular project, and it contains most of your application's source code. Inside the src folder, you'll find the following subdirectories:

app: This folder contains the core application code. It's where you'll create most of your Angular components, services, and modules.

components: Angular components that represent different parts of your application's UI. You can organize these further by feature or functionality.

services: Angular services that handle data retrieval, business logic, and other application-specific tasks.

modules: Angular modules for feature segregation and organization. You can create different modules for various parts of your application.

models: TypeScript interfaces or classes representing data models used in your application.

assets: This folder is for static assets like images, fonts, and other files that will be served directly by the browser.

environments: Contains environment-specific configuration files for your application. You typically have environment.ts for development and environment.prod.ts for production.

styles: CSS or SCSS files for global styles that affect the entire application.

index.html: The main HTML file that serves as the entry point for your application.

angular.json: This file contains configuration settings for your Angular project, including build options, assets, and more.

tsconfig.json: TypeScript configuration file for your project.

package.json: Contains information about your project's dependencies and scripts for running various tasks like development, testing, and building.

node_modules: This folder stores all the external dependencies (libraries and packages) your project uses. It's generated and managed by npm (Node Package Manager).

tslint.json: Configuration for TSLint, a tool for checking TypeScript code against coding standards.

e2e: End-to-end testing files and configuration if you're using Angular's E2E testing framework (usually with Protractor).

karma.conf.js: Configuration file for Karma, which is used for running unit tests.

protractor.conf.js: Configuration file for Protractor, an end-to-end testing framework for Angular applications.

.editorconfig: Contains configuration for code editors to ensure consistent code formatting across the development team.

.gitignore: A file that specifies files and directories that should be ignored by Git (version control).

README.md: Documentation and instructions for developers on how to set up and work with your Angular application.

The specific structure and naming conventions can vary depending on your project's size and complexity. Some teams might choose to follow additional patterns or guidelines like feature-based organization or lazy loading modules for performance optimization. It's important to establish a folder structure that works best for your team and project needs while keeping it organized and maintainable.
