Procession

Procession is an asynchronous message queue library for JavaScript and TypeScript. The current stable version is 3.0.2, released in July 2022. It provides backpressure-aware queues for coordinating concurrent tasks, with a simple API for push and pull operations. Key differentiators include its lightweight footprint, no external runtime dependencies, and support for both Node.js and browser environments. It uses a Promise-based interface and supports multiple queue strategies like FIFO and prioritized queues.
