var charset = require('charset');
var http = require('http');

http.get('http://nodejs.org', function (res) {
  res.on('data', function (chunk) {
    console.log(charset(res.headers, chunk));
    // or `console.log(charset(res, chunk));`
    res.destroy();
  });
});
```

### Detect from String

```js
charset(res.headers['content-type']);
```

### Detect combine with [jschardet]

As you know, `charset` only detect from http response headers and html content-type meta tag.
You can combine with [jschardet] to help you detect the finally charset.

This example codes come from [stackoverflow#12326688](http://stackoverflow.com/a/18712021/2496088):

```js
var request = require('request');
var charset = require('charset');
var jschardet = require('jschardet');

request({
  url: 'http://www.example.com',
  encoding: null
}, function (err, res, body) {
  if (err) {
    throw err;
  }
  enc = charset(res.headers, body);
  enc = enc || jschardet.detect(body).encoding.toLowerCase();
  console.log(enc);
});
```
