# inject-html

Node module for injecting HTML code before or after the `body` tag into the response.

[![Build Status](https://travis-ci.org/alessioalex/inject-html.svg)](https://travis-ci.org/alessioalex/inject-html)

## usage

Installable via npm: `npm i inject-html`.

```js

var inject = injectCode({

  // type: 'append', // default 'prepend'

  code: "alert('injected!!')" // HTML code

});

http.createServer(function(req, res) {

  inject(req, res, function() {

    res.setHeader('Content-Type', 'text/html');

    if (req.url === '/') {

      fs.createReadStream(__dirname + '/page.html').pipe(res);

    } else {

      res.statusCode = 404;

      res.end('Page Not Found\n');

    }

  });

}).listen(1337);

```

Sample output:

before injecting:

```html

  

  inject html example

  
inject-html example

  
content


```

after injecting:

```html

  

  inject html example

alert('injected!!')

  
inject-html example

  
content


```

## caveats

If the content doesn't have a `` tag, this module __will not function properly__.

This module will delete the `content-length` and `content-encoding` (if gzip/inflate) headers.
