How to handle GET and POST request in Node.js Express

Handle GET Request

HTML GET form:

<form method="get" action="/">
    <input type="text" name="username">
    <input type="submit">
</form>

Handler:

app.get('/', function(req, res) {
    res.send('Username: ' + req.query['username']);
});

A good way to remember req.query is that the GET data is stored in the URL query string - querycomes from the query string.

Handle POST Request

HTML POST form:

<form method="post" action="/">
    <input type="text" name="username">
    <input type="submit">
</form>

Handler code:

app.post('/', function(req, res) {
    res.send('Username: ' + req.body.username);
};

There it is! Easy GET and POST request handling in Node.js Express framework.
