Angular Project Structure

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)

✅ Quick Summary

Folder/File Purpose
src/app All your app's logic/components
index.html App root HTML file
main.ts App entry point
angular.json Build & CLI config
package.json Dependencies & npm scripts
tsconfig.json TypeScript settings
