This repository contains a simple setup with a Node.js backend and a React frontend. Both are placed in separate folders:

• backend/: A basic Express server.
• frontend/: A minimal React application configured with webpack and Babel.

Each folder contains its own package.json with the required dependencies and scripts.

The backend expects a MariaDB database. Environment variables are loaded from an .env file. Copy backend/.env.example to backend/.env and fill in the values. The password is stored in encrypted form. To generate the required variables run:

node encryptPassword.js "yourPassword"

This will output ENCRYPTION_KEY, IV and DB_PASSWORD_ENC which you should place in backend/.env along with the database host and user values.

When the server starts it will attempt to connect to the database and log the result.

After configuring the database connection, the OAuth tables will be created automatically when the backend starts. You can also create them manually by running:

node src/db/createOAuthTables.js

This script reads backend/src/db/oauth_tables.sql and ensures the oauth_users and oauth_tokens tables exist. The same logic runs during server startup so the tables are present without an extra step.

The backend exposes Google OAuth endpoints under /auth. Configure GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET in backend/.env. Start the frontend and click OAuth 로그인 to begin the login flow.
