🚇 API Proxy

To better emulate the actual production environment when developing web apps, you can specify paths that should be proxied to another server (e.g. your real API server or a local testing server) in a .proxyrc, .proxyrc.json or .proxyrc.js file.

¶ .proxyrc / .proxyrc.json

In this JSON file, you specify an object where every key is a pattern against which the URL is matched and the value is a http-proxy-middleware options object:

{
  "/api": {
    "target": "http://localhost:8000/",
    "pathRewrite": {
      "^/api": ""
    }
  }
}

This would cause http://localhost:1234/api/endpoint to be proxied to http://localhost:8000/endpoint.

¶ .proxyrc.js

For more complex configurations, a .proxyrc.js file allows you to attach any (connect-compatible) middleware, this example has the same behaviour as the .proxyrc version above.

const { createProxyMiddleware } = require("http-proxy-middleware");

module.exports = function (app) {
  app.use(
    createProxyMiddleware("/api", {
      target: "http://localhost:8000/",
      pathRewrite: {
        "^/api": "",
      },
    })
  );
};
