## What it is
HyperExpress is a high-performance Node.js HTTP and WebSocket server library built on top of uWebSockets.js, exposing a simple Express-like API. It offers routing, middleware, sessions, SSE, and multipart file uploads with significantly higher throughput than Express.

## Use cases
- build a fast http server in node.js
- serve websockets with high throughput
- replace express for better performance
- handle multipart file uploads in node
- implement server-sent events endpoint
- host multiple domains over ssl in one server

## When to choose
- you need maximum HTTP/WebSocket throughput on existing hardware
- you want an Express-like API with better performance
- you need SSE, multipart uploads, or modular routers in Node.js

## When to avoid
- you rely on the full Express middleware ecosystem
- you deploy on Alpine Linux (musl is unsupported and can crash)
- you need ESM-only or async/await-first framework conventions

## Facets
- artifact type: library
