bun add crnt

Overview / Philosophy

• TypeScript - first
• Unopinionated, lightweight, and un-intrusive
• Support for modern constructs (ex: AbortController)
• Performance - optimized for speed and reducing memory leaks.
• Synchronous and asynchronous methods.

The library is a modern replacement for the following popular NPM libraries

• async-mutex
• async-sema
• p-limit
• p-queue

High level structure

Most operations return Promises.

However, there are various synchronous maybe*() methods which operates synchronously. These operations return true if they were successful, false otherwise.

Operations can be cancelled, either by a timeout value or an AbortSignal.
