About async-aid

The async-aid library is a set of utility functions, each providing specific sort of guards or tools for using in common scenarios where async functions are involved. Primary use cases include:

• caching the results of async function calls (memoisation),
• deduplication of HTTP requests or other asynchronous operations,
• automatic retrying the asyncronous operation in case of failure,
• execution of concurrent asynchronous operations in superseding mode based on the launch time,
• creating async functions with execution time limit.

Utilities provided by async-aid work both on the server side (in the Node.js environment) and on the client side (in browsers).
