The request names async-lock, a JavaScript/Node.js async locking library, but none of the candidate sources describes or documents async-lock itself, so no product here can be recommended as the async-lock package. The closest available tools are general-purpose async/concurrency options: async-std (a Rust async library 8) and Node.js as the JavaScript runtime that async-lock runs on 6.
A question back: Do you mean the npm package 'async-lock' for Node.js, or a different language's async locking primitive?
