This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

litenote-jetstream is the backend for Litenote, a blogging platform built on the AT Protocol (Bluesky ecosystem). It has two processes:

1. Jetstream listener (jetstream.ts) — Subscribes to the AT Protocol firehose via @skyware/jetstream, filtering for space.litenote.note records. On create/update events, it upserts notes into a local SQLite database.
2. HTTP API server (server.ts) — An Oak (Deno HTTP framework) server on port 8080 that exposes read-only endpoints to query stored notes.

Both processes share the same SQLite database (src/data/db.ts).

Commands

# Run jetstream listener (dev, with watch)
deno task jetstream

# Run API server (dev, with watch)
deno task server

# Run both for production (as in Docker)
deno task jetstream:prod & deno task server:prod

# Run database migration
deno task migrate

# Lint
deno lint

# Format
deno fmt

Architecture

• Runtime: Deno (not Bun, despite the README). Uses deno.json for task definitions and import maps.
• Database: SQLite via https://deno.land/x/sqlite/mod.ts. DB path is configurable via SQLITE_PATH env var, defaults to notes.db.
• Note schema: Defined as an AT Protocol lexicon in lexicons/space/litenote/note.json. Notes have title, optional images (blob refs), publishedAt, and createdAt. Primary key is (did, rkey).
• API endpoints:
  • GET /notes?cursor=&limit= — paginated notes (all users)
  • GET /:did/notes?cursor=&limit= — paginated notes for a specific DID
• Pagination: cursor-based using rkey, descending order.
