@squarecloud/http-proxy
A Full-Featured HTTP and WebSocket Proxy for Node.js forked from http-party/node-http-proxy.
This fork adds the following features:
- Dependencies updates & security fixes.
- Websocket close before response fixed.
- Memory leak fixed when client closes prematurely.
- Add support for Lookup option. Remove old followRedirects option.
- Support for modifying content of websocket streams.
- Respect NODE_TLS_REJECT_UNAUTHORIZED environment variable.
- Fix for issues when using an Agent, fix the type error when req.socket is undefined.
- Fixed bug when http:/ isn't replaced with: http://
- Fixed X-Forwarded-* not capitalized.
Inspired by the project Ambassify project.
Usage
Install package:
# npm
npm install @squarecloud/http-proxy
# yarn
yarn add @squarecloud/http-proxy
# pnpm
pnpm install @squarecloud/http-proxy
# bun
bun install @squarecloud/http-proxy
Create proxy:
const { createServer } = require("node:http");
const { createProxyServer } = require("@squarecloud/http-proxy");
const proxy = createProxyServer({});
const target = "http://example.com"; /* address of your proxy server here */
const server = createServer(async (req, res) => {
try {
await proxy.web(req, res, { target });
} catch (error) {
console.error(error);
res.statusCode = 500;
res.end("Proxy error: " + error.toString());
}
});
server.listen(80, () => console.log("Proxy is listening on http://localhost"));
Example with WebSocket:
const { createServer } = require("node:http");
const { createProxyServer } = require("@squarecloud/http-proxy");
const proxy = createProxyServer({ ws: true });
const target = "ws://example.com"; /* address of your proxy server here */
const server = createServer(async (req, res) => {
/* ... */
});
server.on("upgrade", async (req, socket, head) => {
try {
// use proxy.ws() instead of proxy.web() for proxying WebSocket requests.
await proxy.ws(req, socket, head, { target });
} catch (error) {
console.error(error);
socket.end();
}
});
server.listen(80, () => console.log("Proxy is listening on http://localhost"));
Some options:
// Options most used in the proxy configuration:
// * ws : <true/false, if you want to proxy websockets>
// * xfwd : <true/false, adds X-Forward headers>
// * secure : <true/false, verify SSL certificate>
// * prependPath: <true/false, Default: true - specify whether you want to prepend the target"s path to the proxy path>
// * ignorePath: <true/false, Default: false - specify whether you want to ignore the proxy path of the incoming request>
// * proxyTimeoutCustomError: true/false, default: false - specify whether you want to throw a custom `ETIMEDOUT` error when the `proxyTimeout` is reached. If false then the default `ECONNRESET` error will be thrown.
