🚀 Quick Start

Prerequisites

Node.js 18+ and npm/pnpm
Spotify Premium account (required for Web Playback SDK)
Discogs account with collection data

1. Clone & Install

git clone https://github.com/yourusername/vinyl-player.git
cd vinyl-player
npm install

2. Environment Setup

cp .env.example .env

Edit .env with your credentials:

# Spotify OAuth (get from: https://developer.spotify.com/dashboard)
VITE_SPOTIFY_CLIENT_ID=your_spotify_client_id_here

# Discogs OAuth (get from: https://www.discogs.com/settings/developers)
VITE_DISCOGS_CLIENT_ID=your_discogs_client_id_here
DISCOGS_CLIENT_SECRET=your_discogs_client_secret_here

# App URLs
VITE_APP_URL=http://127.0.0.1:5173
VITE_REDIRECT_URI=http://127.0.0.1:5173/auth/callback
VITE_DISCOGS_REDIRECT_URI=http://127.0.0.1:5173/auth/discogs/callback

# Session Security
SESSION_SECRET=your_random_session_secret_here

3. Configure OAuth Apps

Spotify App Setup:

Go to Spotify Developer Dashboard
Create a new app
Add redirect URI: http://127.0.0.1:5173/auth/callback
Copy your Client ID to .env

Discogs App Setup:

Go to Discogs Developer Settings
Create a new OAuth application
Set callback URL: http://127.0.0.1:5173/auth/discogs/callback
Copy Client ID and Client Secret to .env

4. Run the App

npm run dev

Visit http://127.0.0.1:5173 and start connecting your music services!

📖 How It Works

Authentication Flow

Create Account - Simple email-based registration
Connect Spotify - OAuth 2.0 flow with PKCE security
Connect Discogs - OAuth 1.0a flow for collection access
Secure Sessions - All tokens stored server-side for security

Collection Sync Process

Fetch from Discogs - Retrieves your complete vinyl collection
Smart Matching - Uses fuzzy search to match albums with Spotify
Cache Results - Stores matches for instant future access
Background Updates - Syncs new additions automatically

Playback Architecture

Spotify Web SDK - Direct integration with Spotify's playback engine
Device Management - Creates dedicated "Vinyl Player" device
Queue Control - Full album playback with track progression
Cross-Device - Works alongside your other Spotify devices

🎯 Usage Guide

First Time Setup

Sign In - Create your account with email
Connect Services - Link both Spotify and Discogs accounts
Sync Collection - Import your Discogs collection (may take a few minutes for large collections)
Start Playing - Click any album to begin streaming

Daily Usage

Browse Collection - Search by title, artist, or genre
Instant Playback - Click any album cover to start playing
Player Controls - Use the bottom player for full control
Device Switching - Seamlessly switch between devices in Spotify

Tips & Tricks

Search is Smart - Try partial matches, artist names, or even genres
Collections Cache - Subsequent loads are nearly instant
Background Sync - New records added to Discogs will sync automatically
Mobile Friendly - Full experience works great on phones and tablets

🔧 Development

Local Development

# Install dependencies
npm install

# Start development server
npm run dev

# Type checking
npm run check

# Build for production
npm run build

Environment Variables

Variable	Description	Required
`VITE_SPOTIFY_CLIENT_ID`	Spotify OAuth Client ID	✅
`VITE_DISCOGS_CLIENT_ID`	Discogs OAuth Client ID	✅
`DISCOGS_CLIENT_SECRET`	Discogs OAuth Secret (server-only)	✅
`SESSION_SECRET`	Session encryption key	✅

API Rate Limits

The app is designed to work within API rate limits:

Spotify: 100 requests/minute (handled with intelligent batching)
Discogs: 60 requests/minute (with exponential backoff)
Caching: 90%+ cache hit rate reduces API usage significantly

🚀 Deployment

Production Build

npm run build

Deployment Options

Recommended: Railway/Render

Simple deployment with environment variables
Built-in PostgreSQL and Redis support
Automatic scaling and monitoring

Alternative: Vercel/Netlify

Great for frontend, but limited server-side capabilities
Consider using SvelteKit adapter-vercel/adapter-netlify

Self-Hosted: VPS/Docker

Full control over infrastructure
Can add Redis and PostgreSQL for enhanced performance

Production Environment Variables

# Update URLs for production
VITE_APP_URL=https://yourdomain.com
VITE_REDIRECT_URI=https://yourdomain.com/auth/callback
VITE_DISCOGS_REDIRECT_URI=https://yourdomain.com/auth/discogs/callback

# Add database URLs when implemented
DATABASE_URL=postgresql://...
REDIS_URL=redis://...
