## install ##

```

$ npm install harmon

```

## examples ##

### Overview ###

------------

In this example the HTML below is returned from the remote server and parsed:

``` html

	

	

		
Nodejitsu Http Proxy

		
& Frames

	


```

  

The following line is removed: 

``` html

& Frames
 

```

And is replaced with: 

``` html 

+ Trumpet

``` 

### Run It! 

----------- 

from your project root:

```

$ cd node_modules/harmon/examples

$ node simple.js

```

Browse to [localhost:8000](http://localhost:8000) and you should see:

### Code

``` js

var http = require('http'),

    connect = require('connect'),

    httpProxy = require('http-proxy');

    var selects = [];

    var simpleselect = {};

        simpleselect.query = '.b';

        simpleselect.func = function (node) {

           node.createWriteStream().end('
+ Trumpet
');

        }


        selects.push(simpleselect);

        //

        // Basic Connect App

        //

        var app = connect();

        var proxy = httpProxy.createProxyServer({

              target: 'http://localhost:9000'

        })

        //Additional true parameter can be used to ignore js and css files. 

        //app.use(require('../')([], selects, true));

        app.use(require('../')([], selects));

        app.use(function (req, res) {

                   proxy.web(req, res);

                });

        http.createServer(app).listen(8000);

        http.createServer(function (req, res) {

             res.writeHead(200, { 'Content-Type': 'text/html' });

               res.write('
Nodejitsu Http Proxy
& Frames
');

                 res.end();

        }).listen(9000);
