Function-Based Tool Use

Coming Soon

This tutorial is under development. Check back soon for a complete walkthrough.

What You'll Learn

This tutorial will walk you through writing JavaScript functions that AI agents can invoke as tools, using the raisin.* API to read and write data, execute SQL, and call external services.

Planned Outline

1. Prerequisites — RaisinDB instance running, basic familiarity with JavaScript
2. Create a simple function — write a handler that reads and returns a node
3. Use raisin.nodes — create, read, update, and delete nodes from a function
4. Use raisin.sql — execute SQL queries and process results
5. Use raisin.http — call an external API from a sandboxed function
6. Use raisin.events — emit events that trigger other functions
7. Configure triggers — set up event-based, HTTP, and schedule triggers
8. Resource limits — understand memory, time, and concurrency constraints
9. Build an agent tool — complete example of a function an AI agent calls to process messages and store findings
