Easy-to-use HTTP Proxy Kit for Node.js.
Supported by this library:
- Rewrite response status and headers
- Customize requests using Node.js's built-in
http.request - Smartly rewrite the location header based on the base path
- Proxy for subpaths and base at any subpath
- Zero dependencies, requiring only built-in Node.js modules
Not supported:
WebSocket support is not available and there are no plans to add it.
If WebSocket support is crucial for your application, consider using a different library such as http-proxy-middleware.
Here's how you can use hpk to create proxy servers:
import { createServer } from "node:http";
import { createProxyMiddleware } from "hpk";
// Simple proxy server
createServer(createProxyMiddleware("https://example.net")).listen(8080);
// Proxy server with specific configuration
createServer(
createProxyMiddleware({
base: "/npm/",
target: "https://cdn.jsdelivr.net/npm/",
location: "rewrite",
})
).listen(8081);
// Proxy server with conditional middleware
createServer((req, res) => {
createProxyMiddleware({
base: "/npm/",
target: "https://cdn.jsdelivr.net/npm",
location: "rewrite",
})(req, res);
createProxyMiddleware({
base: "/gh/",
target: "https://cdn.jsdelivr.net/gh",
location: "rewrite",
})(req, res);
res.end("Resource not found");
}).listen(8082);This middleware is also compatible with Express:
const express = require("express");
const { createProxyMiddleware } = require("./src");
const app = express();
app.use("/example/", createProxyMiddleware("https://example.net"));# use npx
npx hpk -h
# or install globally
npm i -g hpk
# example
hpk https://example.net --port=8080 --cors=*
