DataHub Proxy Middleware

datahub-proxy-middleware is an Express/Connect-compatible HTTP server middleware designed to proxy API requests to a Macaca.js DataHub instance. It facilitates API mocking and data management during development by allowing developers to define flexible proxy rules that redirect specific paths to a running DataHub server for mock data retrieval. The current stable version, 5.0.3, was released in March 2024, indicating active maintenance within the Macaca.js ecosystem. Key differentiators include its tight integration with `macaca-datahub`, robust configuration options for defining proxy routes (e.g., dynamic ports, hostnames, and path matching with `@macaca-project/path-to-regexp`), and its suitability for development environments, particularly when integrated with tools like `webpack-dev-server` to provide mock data without requiring a live backend.
