# harmon
A middleware component for [node-http-proxy](https://github.com/nodejitsu/node-http-proxy) using [trumpet](https://github.com/substack/node-trumpet) to parse and transform the response from the proxied server.
[](http://travis-ci.org/No9/harmon)
## 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);
```
