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