DieselEngineScripting Documentation

ES2023 scripts on GraalVM — with full database, HTTP routing, WebSocket, and service access baked in.

Database (JDBC)

Full PostgreSQL access via prepared statements. JSONB columns, arrays, and raw SQL — all from JavaScript.

Route HTTP GET, POST, and DELETE requests to JavaScript handler functions. Full request/response control.

Persistent connections with rooms, broadcast, and per-session state. Build real-time features in minutes.

Schedule scripts with cron expressions or run them once at boot. Same runtime, same APIs, no extra config.

Connect to Redis for caching and pub/sub. Use MinIO for S3-compatible file storage with optional encryption.

Spawn autonomous LLM-powered agent runs from your scripts. They have access to every MCP tool on the platform.
