watch-party/backend

Backend (Go + Gin)

REST API that serves the schedule/time endpoints and current episode control. Built in Go, containerized with a multi-stage Dockerfile.

Prerequisites

• Go 1.22+
• PostgreSQL reachable (uses env-driven DSN pieces)
• golang-migrate not required locally (migrations shipped in repo)

Env

The server builds its DSN from:

• PGHOST, POSTGRES_PORT, POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DB, PGSSLMODE
• ADDR (listen address, default :8082)
• GIN_MODE (e.g., release)

Commands

# Run locally (expects Postgres per env)
go run ./cmd/server

# Run migrations
go run ./cmd/migrate

# Tests
go test ./...

Docker build (used by compose)

docker build -t watchparty-backend .

Compose uses the same image for api and the one-off migrate job.

Endpoints (key)

• GET /api/v1/time — server time for client clock sync
• GET /api/v1/current — current schedule item
• POST /api/v1/current — set current episode (expects { id, start_time? })
• GET /api/v1/shows — list of episodes
• GET /healthz — health check
