This package contains the DB sync server code and tests used by Logseq. It includes the Cloudflare Worker implementation and a Node.js adapter for self-hosting.

Requirements

Node.js (see repo root for required version)
Clojure (for shadow-cljs builds)

Build and Test

Cloudflare Worker

cd deps/db-sync
yarn watch

# open another terminal
cd deps/db-sync/worker
wrangler dev

D1 Schema (Worker)

The worker no longer initializes schema at request time. Apply the D1 schema via migrations during deployment/CI.

cd deps/db-sync/worker
wrangler d1 migrations apply logseq-sync-graph-meta-staging --env staging
wrangler d1 migrations apply logseq-sync-graphs-prod --env prod

Node.js Adapter (self-hosted)

Build the adapter:

cd deps/db-sync
npm run build:node-adapter

Run the adapter with Cognito auth:

./start.sh

Run the adapter with a static token (local dev):

export DB_SYNC_AUTH_DRIVER=static
export DB_SYNC_AUTH_TOKEN=dev-token
export DB_SYNC_STATIC_USER_ID=user-1
export DB_SYNC_PORT=8787
node worker/dist/node-adapter.js

Tests

Run db-sync tests (includes Node adapter tests):

cd deps/db-sync
npm run test:node-adapter

Local Sandbox Agent (for agent sessions)

Use the local sandbox-agent repo at ~/Codes/projects/sandbox-agent:

cd deps/db-sync
./scripts/start-local-sandbox-agent.sh

Then run db-sync worker with:

SANDBOX_AGENT_URL=http://127.0.0.1:2468

If sandbox-agent runs with token auth, also set:

SANDBOX_AGENT_TOKEN=...

Smoke test a Codex-backed session:

cd deps/db-sync
BASE_URL=http://127.0.0.1:8787 ./scripts/start-weather-session.sh

The control plane forwards each task message through sandbox-agent /v1/sessions/{id}/messages/stream and relays runtime events to /sessions/{id}/stream.

Runtime Provider

Agent runtime is selected by AGENT_RUNTIME_PROVIDER:

sprites (default): provisions a Sprite and runs sandbox-agent inside it.
local-dev: uses SANDBOX_AGENT_URL directly.
cloudflare: provisions a sandbox first, then connects to the sandbox-hosted sandbox-agent.

For cloudflare, bind and export Sandbox in the Worker and configure the container image in worker/wrangler.toml ([[containers]] class_name = "Sandbox").
