Angular Project Structure

📁 Angular Project Structure Overview

🔹 `e2e/`

• End-to-End Testing folder using Protractor or Cypress.
• Contains tests that simulate real user interactions.

🔹 `node_modules/`

• Contains all installed npm packages.
• Automatically generated—no need to modify this manually.

🔹 `src/` (This is where the real magic happens)

🔸 `app/`

• Your main application logic lives here.
• Contains components, services, modules, etc.

File	Description
app.module.ts	Root module that bootstraps your app.
app.component.ts	Logic/controller of the root component.
app.component.html	View/template for the root component.
app.component.css	Styles for the root component.

You’ll also create feature components and services inside this folder.

🔸 `assets/`

• Static files like images, icons, etc.
• These are served as-is without processing.

🔸 `environments/`

• Used to define environment-specific variables (e.g., dev or prod).
• Contains environment.ts and environment.prod.ts.

🔸 `index.html`

• Entry HTML file.
• Angular renders the app inside the <app-root></app-root> tag here.

🔸 `main.ts`

• The main entry point for the app.
• Bootstraps the root module (AppModule).

🔸 `styles.css`

• Global styles for your app.

🔸 `angular.json`

• Angular CLI configuration.
• Defines how the app is built, tested, and deployed.

🔸 `package.json`

• Lists dependencies and scripts.
• Useful for managing npm packages and running commands like ng serve.

🔸 `tsconfig.json`

• TypeScript configuration.
• Controls how TypeScript compiles your code.

🔸 `karma.conf.js` & `test.ts`

• Used for unit testing configuration.

🔁 App Flow

main.ts → AppModule → AppComponent → Template (HTML) → Styles (CSS)
