## What it is
Micro is a minimal asynchronous HTTP framework for building microservices in Node.js using async/await. It provides a tiny, dependency-light core for handling HTTP requests as simple async functions.

## Use cases
- build lightweight http microservices in node.js
- create small async api endpoints
- replace express with a minimal http server
- write serverless-style http functions
- handle json apis with async/await

## When to choose
- you want a tiny, fast http server with minimal abstraction
- you prefer async/await-based request handling
- you're building small single-purpose microservices or serverless functions

## When to avoid
- you need batteries-included features like routing tables, middleware ecosystems, or validation
- you're building a large monolithic web application
- you need websockets or advanced protocol support out of the box
