Koa is a lightweight, expressive web framework for Node.js that uses modern async functions for middleware composition. It provides a minimal core without bundled middleware, allowing developers to build robust APIs and web applications with fine‑grained control.
Use cases
- build a RESTful API with async/await middleware
- create a lightweight web server for microservices
- replace Express in a Node.js project for better error handling
- develop custom middleware pipelines for request processing
- prototype a web application with minimal built‑in features
When to choose
- you need a minimal core and want to add only the middleware you require
- your project relies heavily on async/await for clean error handling
- you prefer a framework designed by the Express team with a modern API
- you want fine‑grained control over request/response handling
When to avoid
- you need a full‑featured framework with many built‑in utilities out of the box
- your team is unfamiliar with async/await patterns
- you require extensive built‑in routing or view rendering features
