Drift FM

Mood radio you host yourself.

Drop in your mp3s, tag them by mood, hit play. Continuous shuffled playback per mood. No accounts, no tracking, no frameworks.

Stack: Go + SQLite + vanilla JS

---

Quick Start

# 1. Initialize the database
make db-init

# 2. Import your music (interactive — pick mood per batch)
make import-batch ARGS="/path/to/your/music"

# 3. Run
make run
# → http://localhost:8080

---

End-to-End Workflow

1. Set Up

git clone https://github.com/1mb-dev/driftfm.git
cd driftfm
make db-init

Prerequisites: Go 1.25+, SQLite3 CLI, ffmpeg/ffprobe (for audio import and normalization).

2. Add Content

Option A — Batch import (recommended):

# Import a directory of MP3s — prompts for mood selection
make import-batch ARGS="/path/to/focus-tracks"

Option B — Single track with metadata:

make import FILE=song.mp3 MOOD=focus

The import script (scripts/import-track.sh) supports additional flags:

# Full metadata example
./scripts/import-track.sh song.mp3 \
  --mood calm \
  --title "Ocean Waves" \
  --artist "Your Name" \
  --energy low \
  --bpm 72 \
  --intensity 8 \
  --time evening

Run ./scripts/import-track.sh --help for all options.

3. Normalize Audio (Optional)

Normalize loudness across your library for consistent playback:

# Single file
make normalize FILE=audio/tracks/a/ocean-waves-001a.mp3

# Batch (all files in a directory)
./scripts/normalize-batch.sh audio/tracks/

4. Run the Server

make run
# → http://localhost:8080

Or build a binary:

make build
./bin/server

5. Update the Database

After adding new tracks or modifying the schema:

# Run pending migrations
make db-migrate

# Re-initialize from scratch (destructive)
make db-init

Make Targets

Development:
  make build          Build the server binary
  make run            Run the server (localhost:8080)
  make dev            Run with hot reload (requires air)
  make test           Run all tests
  make clean          Remove build artifacts

Code Quality:
  make check          Full quality gate (fmt, vet, lint, test)
  make fmt            Format code
  make vet            Run go vet
  make lint           Run linter (requires golangci-lint)

Setup & Database:
  make setup          Create data/ and audio/ directories
  make db-init        Initialize SQLite database
  make db-migrate     Run pending migrations

Audio:
  make import FILE=<path> MOOD=<mood>   Import single track
  make import-batch ARGS=<dir>          Import directory of tracks
  make normalize FILE=<path>            Normalize audio file

Configuration

Environment variables override config.yaml values (see .env.example):

Variable	Default	Description
PORT	8080	Server port
DB_PATH	data/inventory.db	SQLite database path
AUDIO_STORE_LOCAL_PATH	audio	Local audio directory

---

Deploy

Bare Metal / VPS

# Build for Linux
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o bin/server ./cmd/server

# Copy to your server:
scp -r bin/server web/ config.yaml scripts/ user@host:/opt/driftfm/

# On the server:
mkdir -p /opt/driftfm/data /opt/driftfm/audio/tracks
sqlite3 /opt/driftfm/data/inventory.db < /opt/driftfm/scripts/migrations/schema.sql
PORT=8080 /opt/driftfm/server

For production, put a reverse proxy (Caddy, nginx) in front for TLS and set up a systemd unit for process management.

API

Endpoint	Description
GET /api/moods	List moods with track counts
GET /api/moods/:mood/playlist	Shuffled playlist for mood
POST /api/tracks/:id/play	Record listen event
GET /health	Health check
GET /ready	Readiness probe

Architecture

Browser ←→ Go server ←→ SQLite
              ↓
         audio/tracks/

• Backend: Single Go binary, net/http, no framework
• Database: SQLite with WAL mode (pure Go driver, no CGO)
• Frontend: Vanilla JS, CSS variables, Web Audio API
• Audio: Local filesystem (audio/tracks/)
