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)

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)

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...
    }
});
