equinox-project/equinox-js
This system is an event-sourcing framework called Equinox, designed to simplify the construction of domain-driven applications with persistent state management. It provides a core library for handling streams, codecs, and deciders, supported by pluggable storage backends including PostgreSQL (MessageDB), Amazon DynamoDB, libSQL, and in-memory stores. The repository also includes example applications demonstrating HTTP APIs, background processing, and complex process managers, alongside a visualization tool for exploring event data.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 4 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 8374fe9d54 — the exact code this score is about.
- Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
