What it is

Micro is a small Node.js library from Vercel for writing HTTP microservices using async and await. It focuses on handling requests and returning responses with very little setup. The README provided here is truncated, so details beyond that core purpose are not confirmed.

  • Write a small HTTP endpoint that returns JSON from an async function
  • Split a larger backend into separate small services
  • Deploy a single-purpose API function on Vercel

Great for

  • Developers who want a minimal HTTP service in Node.js
  • Teams building small single-purpose endpoints or microservices
  • People already familiar with async/await in JavaScript or TypeScript

Not ideal for

  • Beginners looking for a full web framework with routing, templates, and many built-in features, since the README excerpt does not describe those
  • Projects that need a long-running, feature-rich server with a large plugin ecosystem, since this excerpt does not show one

Downloads

Strengths

  • Small, focused scope centered on async HTTP handlers
  • MIT licensed and open source
  • Backed by the Vercel organization and has a large star count on GitHub

Trade-offs

  • The README excerpt is truncated, so setup and API details could not be verified here
  • Its scope is narrow, so you may need other libraries for routing, middleware, or databases
  • Latest release info shows no binaries, so use is through the code or package manager
