Angular Project Structure
Angular Project Structure
When you create a new Angular project using the Angular CLI, it generates a well-defined structure to house your application's code and assets. Let's break down the essential parts:
├── src
│ ├── app
│ │ ├── app.component.html
│ │ ├── app.component.spec.ts
│ │ ├── app.component.ts
│ │ ├── app.module.ts
│ │ └── app.routing.module.ts
│ ├── assets
│ ├── environments
│ │ ├── environment.prod.ts
│ │ └── environment.ts
│ ├── favicon.ico
│ ├── index.html
│ ├── main.ts
│ ├── polyfills.ts
│ ├── styles.css
│ └── test.ts
└── angular.json
src Folder
The src
folder is where the heart of your Angular application resides. It contains all the source code and assets required for your project.
app Folder
The app
folder is the root of your application's components, modules, and services. Let's examine its key parts:
- app.component.html: The main template for your application, which typically houses the root component's view.
- app.component.spec.ts: Unit test file for the
app.component.ts
. - app.component.ts: The root component class that defines the logic and data for the application.
- app.module.ts: The main module that bootstraps the application. It imports and configures other modules and components.
- app.routing.module.ts: Handles routing for your application. It defines routes and links between different components.
assets Folder
The assets
folder holds static assets, such as images, fonts, and data files. These are used directly by your application and do not need to be processed.
environments Folder
The environments
folder contains configuration files for different environments (e.g., development, production). It's useful for separating settings based on your environment.
Do You Know?
Angular follows a modular architecture, breaking down your application into logical units called modules. Each module has its own components, directives, pipes, and services.
favicon.ico
This file contains the favicon for your website, which is displayed in browser tabs and bookmarks.
index.html
The main HTML file for your application. It provides the base structure for your web page and includes scripts and styles that bootstrap your Angular app.
main.ts
The entry point for your Angular application. It bootstraps the app.module.ts
and starts the application.
polyfills.ts
Contains polyfills that provide compatibility with older browsers for features that aren't supported natively.
styles.css
The main stylesheet for your application. It can be used to define global styles and overrides.
test.ts
Contains configuration for running unit and end-to-end tests.
angular.json
This file is the central configuration file for your Angular project. It defines settings for different environments, build configurations, and project structure.
Important Note
The project structure generated by the Angular CLI is highly customizable. You can adjust it based on the size and complexity of your application.
Summary
- Angular projects have a well-organized structure that promotes code reusability, maintainability, and scalability.
- The
src
folder contains all the source code and assets, with theapp
folder serving as the application's root. - Angular follows a modular architecture, where modules break down the application into logical units.
- The
angular.json
file provides central configuration for your project.
