MoodSwipe

MERN stack app for mood-based music discovery with Tinder-style swipes. Backend uses Express + MongoDB + YouTube Data API v3; frontend is React (Vite) with Framer Motion.

Prerequisites

• Node.js 18+
• MongoDB (local or Atlas)
• YouTube Data API v3 API key

Setup

1. Copy .env.example to server/.env and fill in YOUTUBE_API_KEY, MONGODB_URI, and PORT (must match what Vite reads for dev — see .env.example).

2. Install and run (from repo root):

npm install
npm run dev

• API: http://localhost:<PORT> (default 5000 in .env.example)
• UI: URL printed by Vite (starts at 5173, may use next free port)

For production builds, set VITE_API_URL to your public API URL when building the client.
