Async Express/Connect Middleware Wrapper

async-middleware is a utility package designed to simplify error handling for asynchronous middleware functions within web frameworks like Express and Connect. It wraps an `async` or Promise-returning function, automatically catching rejected Promises and forwarding the error to the `next(err)` callback, preventing uncaught Promise rejections from crashing the application. The package is currently at version 1.2.1 and appears to be in a maintenance state, with the last release being in 2017 focusing on minor fixes and dependency cleanups rather than new features. Its key differentiator is its singular focus on robust async error piping for traditional middleware stacks, providing a lightweight alternative to more comprehensive async libraries. It ships with TypeScript types, enhancing developer experience for type-safe applications.
