Creating Custom Sources and Reactions

Mon, 01 Jan 0001 00:00:00 +0000

drasi-lib ships with plugins for common systems — PostgreSQL, HTTP, gRPC, MSSQL, and more (see Available Sources and Available Reactions). When your application needs to watch or react to a system that isn’t on that list, you implement two small async traits — Source and Reaction — and drasi-lib handles query evaluation, dispatch, and recovery for you.

This guide walks through both traits with illustrative code that does not compile as shown. If you’d rather have an AI agent generate a production-ready plugin — including tests and docs — see Source and Reaction Creation Agents instead. That workflow uses the same traits described here.
