inject-html

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

Build Status

usage

Installable via npm: npm i inject-html.

var inject = injectCode({
  // type: 'append', // default 'prepend'
  code: "<script>alert('injected!!')</script>" // 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:

<!DOCTYPE HTML>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>inject html example</title>
</head>
<body>
  <h3>inject-html example</h3>
  <p>content</p>
</body>
</html>

after injecting:

<!DOCTYPE HTML>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>inject html example</title>
</head>
<body><script>alert('injected!!')</script> 
  <h3>inject-html example</h3>
  <p>content</p>
</body>
</html>

caveats

If the content doesn't have a <body> tag, this module will not function properly. This module will delete the content-length and content-encoding (if gzip/inflate) headers.
