Socks proxy for Node builtin (also undici) fetch.
npm install fetch-socksFetch http://example.com through socks5://[::1]:1080.
import { socksDispatcher } from "fetch-socks"; const dispatcher = socksDispatcher({ type: 5, host: "::1", port: 1080, //userId: "username", //password: "password", }); const response = await fetch("http://example.com", { dispatcher }); console.log(response.status); console.log(await response.text());Set the proxy globally.
import { socksDispatcher } from "fetch-socks"; const dispatcher = socksDispatcher({ /* ... */}); global[Symbol.for("undici.globalDispatcher.1")] = dispatcher;TypeScript example, fetch through proxy chain with two SOCKS proxies.
import { fetch } from "undici"; import { socksDispatcher, SocksProxies } from "fetch-socks"; const proxyConfig: SocksProxies = [{ type: 5, host: "::1", port: 1080, }, { type: 5, host: "127.0.0.1", port: 1081, }]; const dispatcher = socksDispatcher(proxyConfig, { connect: { // set some TLS options rejectUnauthorized: false, }, }); const response = await fetch("https://example.com", { dispatcher });create a socks connection over HTTP tunnel with socksConnector.
import { Client, Agent } from "undici"; import { socksConnector } from "fetch-socks"; const socksConnect = socksConnector({ type: 5, host: "::1", port: 1080, }); async function connect(options, callback) { // First establish a connection to the HTTP proxy server (localhost:80). const client = new Client("http://localhost:80"); const { socket, statusCode } = await client.connect({ // Tell the server to connect to the next ([::1]:1080) path: "[::1]:1080", }); if (statusCode !== 200) { callback(new Error("Proxy response !== 200 when HTTP Tunneling")); } else { // Perform socks handshake on the connection. socksConnect({ ...options, httpSocket: socket }, callback); } } const dispatcher = new Agent({ connect }); const response = await fetch("https://example.com", { dispatcher });Create an Undici connector which establish the connection through socks proxies.
proxiesThe proxy server to use or the list of proxy servers to chain. If you pass an empty array it will connect directly.connectOptions(optional) The options used to perform directly connect or TLS upgrade, see here
Create a Undici Agent with socks connector.
proxiesSame assocksConnector's.options(optional) Agent options. Theconnectproperty will be used to create socks connector.
import { socksConnector, socksDispatcher } from "fetch-socks"; import { Agent } from "undici"; const proxy = { type: 5, host: "::1", port: 1080 }; const connect = { /* ... */ }; const agentOptions = { /* ... */ }; socksDispatcher(proxy, { ...agentOptions, connect }); // Is equivalent to new Agent({ ...agentOptions, connect: socksConnector(proxy, connect) });
