7f349d8e

Feed Server Deployment#

Current: dp1-feed-v2 (Go + Postgres)#

As of April 2026, feed.aesthetic.computer runs dp1-feed-v2 — a Go binary backed by PostgreSQL 16, hosted on the lith VPS (209.38.133.33).

  • Source: https://github.com/display-protocol/dp1-feed-v2
  • Binary: /opt/dp1-feed/dp1-feed
  • Config: /opt/dp1-feed/config.yaml (source of truth: lith/dp1-feed-config.yaml)
  • Env: /opt/dp1-feed/.env (API key, signing key, database URL)
  • Service: systemctl {start,stop,restart,status} dp1-feed
  • Logs: journalctl -u dp1-feed -f
  • Port: 8787 (reverse proxied via Caddy)
  • Database: PostgreSQL dp1_feed on localhost, user dp1feed

Rebuilding#

ssh root@lith.aesthetic.computer
cd /opt/dp1-feed-build/dp1-feed-v2
git pull
CGO_ENABLED=0 go build -o dp1-feed ./cmd/server
cp dp1-feed /opt/dp1-feed/dp1-feed
systemctl restart dp1-feed

Initial Setup#

Run lith/scripts/setup-dp1-feed.sh on the VPS. It installs Go, PostgreSQL, clones the repos, builds the binary, and creates the systemd service.

API Endpoints#

  • GET /health — liveness
  • GET /api/v1 — API info
  • GET /api/v1/playlists — list playlists
  • GET /api/v1/channels — list channels (requires extensions enabled)
  • GET /api/v1/playlist-groups — list playlist groups
  • GET /api/v1/playlist-items — list playlist items
  • PUT /api/v1/registry/channels — update curated channel registry

Auth: Authorization: Bearer <API_KEY> for all write operations.

Legacy (archived)#

The previous V1 deployment used Cloudflare Workers (TypeScript/Hono) with KV storage. That code lives in feed/dp1-feed/ and is no longer deployed.
