Getting Started (Local Setup)

1) Clone & Install

git clone https://github.com/AnasMultani17/Social-Media-App-Backend-Deployment.git
cd Social-Media-App-Backend-Deployment
npm install

2) Environment Variables

Create an environment file (commonly .env). This backend expects at least:

PORT=7000
MONGO_URI=
CORS_ORIGIN=http://localhost:3000
ACCESS_TOKEN_SECRET=
ACCESS_TOKEN_EXPIRY=
REFRESH_TOKEN_SECRET=
REFRESH_TOKEN_EXPIRY=

CLOUDINARY_CLOUD_NAME=
CLOUDINARY_API_KEY=
CLOUDINARY_API_SECRET=

3) Run the Server

# development
npm run dev

# production
npm start

Server starts on:

• http://localhost:7000 (by default)

---

Authentication

Protected routes use verifyJWT middleware and accept tokens from:

• Cookie: accessToken
• Header: Authorization: Bearer <token>

---

File Uploads

This backend uses multer memory storage, meaning files are kept in RAM during the request. Common multipart fields:

• User registration: avatar, coverimage
• Video publish: videoFile, thumbnail
• Update avatar: avatar
• Update cover image: coverimage

---

CORS

CORS is enabled with credentials support and a configurable origin via:

• CORS_ORIGIN (defaults to http://localhost:3000)

The app also explicitly sets Access-Control-Allow-Origin to:

• https://new-social-media-app-frontned.vercel.app
