Below a quick example how to use appendit:
The index.html looks like that:

<head>
<title></title>
<!-- anchor -->
</head>
<body>
</body>
</html>
Call the appendit function with the following parameters:
var fs = require('fs');
var appendit = require('appendit');
var content = appendit({
source: fs.readFileSync('index.html', 'utf8'),
anchor: '<!-- anchor -->',
content: [
'<script src="main.js"></script>'
]
});
fs.writeFileSync('index.html', content);
Output:
<html>
<head>
<title></title>
<script src="main.js"></script>
<!-- anchor -->
</head>
<body>
</body>
</html>

Let's add a headline to the body:
appendit({
source: fs.readFileSync('index.html', 'utf8'),
anchor: '</body>',
content: [
'<h1>Hello Node!</h1>'
]
})
Output:
<html>
<head>
<title></title>
<script src="main.js"></script>
<!-- anchor -->
</head>
<body>
<h1>Hello Node!</h1>
</body>
</html>
