Continuation-Local Storage (CLS) provides a mechanism for managing state across asynchronous function calls in Node.js, similar to thread-local storage in threaded programming. It allows developers to set and retrieve values that are scoped to the lifetime of chains of function calls, making it particularly useful for maintaining context in web applications, such as user sessions or request-specific data. This project is ideal for Node.js developers who need to manage state across asynchronous operations without relying on global variables or passing context through every function call.
