Getting Started

Prerequisites

• Node.js
• Angular CLI

Setup & Local Development

• Clone this repository: git clone git@github.com:nikosanif/angular-authentication.git
• cd angular-authentication
• Install dependencies: npm install
• Serve the Angular app: npm start
• Open your browser at: http://localhost:4200

Use it as a Template

The main purpose of this repository is to provide a simple Angular application that demonstrates best practices for user authentication and authorization flows. The application is configured to use a fake API server (interceptor) that simulates the backend server. Also, it includes two state management libraries, NgRx and NGXS, so you can choose which one to use.

If you want to use this repository as a template for your project, you can follow these steps:

• Clone this repository
• Remove fake API:
  • Delete src/app/core/fake-api folder
  • Remove all references from the fake-api folder
  • Remove the fakeApiInterceptor from app.config.ts
• Choose the state management library you want to use:
  • NgRx: Remove src/app/auth/store/ngxs folder and the index.ngxs.ts file
  • NGXS: Remove src/app/auth/store/ngrx folder and the index.ngrx.ts file
  • Rename the index.XXX.ts file to index.ts in the src/app/auth/store folder
  • Update the app.store.ts file to import the correct store module
  • Remove all unused packages from package.json
• Update the Google Analytics tracking ID by replacing UA-XXXXX-Y in the index.html file and in the src/app/core/services/google-analytics.service.ts file. Or remove the Google Analytics service if you don't want to use it.

Useful Commands

• npm start - starts a dev server of Angular app
• npm run build:prod - builds full prod build
• npm run lint - linting source code of this project
• npm run format:check - runs prettier to check for formatting errors
• npm run format:write - runs prettier to format whole code base
• npm run release - runs release-it to create new release
