OAuth2 Authentication with Golang and React

This project demonstrates OAuth2 authentication using Golang for the backend API and React for the frontend application.

Getting Started

Prerequisites:

• Golang (>= 1.22.5) installed: Download Golang
• Node.js and npm (or yarn) installed: Download Node.js
• Provider account (Google) to register your application

Installation:

1. Clone this repository:

   git clone https://github.com/iarsham/oauth2-example.git
   

2. Navigate to the project directory:

   cd oauth2-example
   

3. Install Go dependencies:

   go mod download
   

4. Install React dependencies:

   cd client
   npm install
   

Configuration

1. Provider Registration:

   • Visit your chosen provider's developer console (e.g., Google Cloud Platform for Google OAuth2).
   • Create a new project or select an existing one.
   • Enable the OAuth2 API for your project.
   • Create OAuth credentials, specifying:
     • Authorized JavaScript origins: The URL of your React application (e.g., http://localhost:3000).
     • Authorized redirect URIs: A redirect URI where the provider will send the authorization code after successful login (e.g., http://localhost:3000).
   • Copy the Client ID and Client Secret provided by the provider.

2. Add yaml properties in configs folder (Golang):

   • Fill the variables with your specific value(Postgres user, password, ...):
   • Also fill Client-ID in client/src/index.tsx for integrate with google and backend

Running the Application

1. Start the Golang backend server:

   go run ./cmd/web
   

2. Start the React development server:

   cd client
   npm start
   

3. Access your React application in a web browser (usually http://localhost:3000).
