# socks ## Migrating from v1 For the most part, migrating from v1 takes minimal effort as v2 still supports factory creation of proxy connections with callback support. ### Notable breaking changes - In an options object, the proxy 'command' is now required and does not default to 'connect'. - **In an options object, 'target' is now known as 'destination'.** - Sockets are no longer paused after a SOCKS connection is made, so socket.resume() is no longer required. (Please be sure to attach data handlers immediately to the Socket to avoid losing data). - In v2, only the 'connect' command is supported via the factory SocksClient.createConnection function. (BIND and ASSOCIATE must be used with a SocksClient instance via event handlers). - In v2, the factory SocksClient.createConnection function callback is called with a single object rather than separate socket and info object. - A SOCKS http/https agent is no longer bundled into the library. For informational purposes, here is the original getting started example from v1 converted to work with v2. ### Before (v1) ```javascript var Socks = require('socks'); var options = { proxy: { ipaddress: "202.101.228.108", port: 1080, type: 5 }, target: { host: "google.com", port: 80 }, command: 'connect' }; Socks.createConnection(options, function(err, socket, info) { if (err) console.log(err); else { socket.write("GET / HTTP/1.1\nHost: google.com\n\n"); socket.on('data', function(data) { console.log(data.length); console.log(data); }); // PLEASE NOTE: sockets need to be resumed before any data will come in or out as they are paused right before this callback is fired. socket.resume(); // 569 // <Buffer 48 54 54 50 2f 31 2e 31 20 33 30 31 20 4d 6f 76 65 64 20 50 65... } }); ``` ### After (v2) ```javascript const SocksClient = require('socks').SocksClient; let options = { proxy: { ipaddress: "202.101.228.108", port: 1080, type: 5 }, destination: { host: "google.com", port: 80 }, command: 'connect' }; SocksClient.createConnection(options, function(err, result) { if (err) console.log(err); else { result.socket.write("GET / HTTP/1.1\nHost: google.com\n\n"); result.socket.on('data', function(data) { console.log(data.length); console.log(data); }); // 569 // <Buffer 48 54 54 50 2f 31 2e 31 20 33 30 31 20 4d 6f 76 65 64 20 50 65... } }); ```
