express-http-proxy

Express middleware to proxy HTTP requests to another host and pass the response back. Current stable version is 2.0.3, targeting Node 16, 18, 20. Supports streaming, Promises, and customizable request/response transforms via decorators. Key differentiators: simple API with memoizable host selection, path resolution, and body decoration; streaming by default with automatic fallback to buffering when response modifiers are used.
