## 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();

}
});
```
### 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...
}
});
