Promise-Queue

sb-promise-queue is a lightweight JavaScript/TypeScript utility library designed to manage and control the concurrency of asynchronous operations using a promise-based queue. Its current stable version is 2.1.1. It allows developers to specify a maximum number of promises that can run simultaneously, preventing resource exhaustion or rate-limiting issues. Key differentiators include its minimalistic and intuitive API, built-in TypeScript type definitions for enhanced developer experience, and clear methods such as `add`, `onIdle`, and `waitTillIdle` for effective task flow management. This library is particularly useful for scenarios requiring controlled execution of potentially resource-intensive async tasks, like API calls or data processing, ensuring stability and performance. While a specific release cadence is not explicitly stated, as a focused utility, updates are generally driven by bug fixes or minor enhancements rather than frequent feature additions.
