node-express error : express deprecated res.send(status): Use res.sendStatus(status) instead

Question

I am trying to send an integer via response.send() but I keep getting this error

express deprecated res.send(status): Use res.sendStatus

Answer 1

As long as you're not sending String or Object/Array data you get an error. Solution convert your data to string:

app.get('/runSyncTest', function(req, res) {
    var number = 5000;
    res.send((number).toString()); //Number is converted with toString()
});

Answer 2

You could try this:

res.status(200).send((results[0].id).toString());

Guys are right - it doesn't allow numbers. Prooflink: http://expressjs.com/4x/api.html#res.send

Answer 3

(as mentioned in the comments already)

The manual states:

The body parameter can be a Buffer object, a String, an object, or an Array.

So integers aren't directly supported and need to be converted to one of those types first. For instance:

response.send(String(idTest));

Answer 4

Use like this,

res.status(404).send('Page Not found');

Answer 5

This is because you are sending numeric value in the res.send.

You could send a json object or convert it to string.

Answer 6

I am getting a deprecated warning in node-express typescript project due to res.send(403);

Solution 1 -

res.sendStatus(403);

Solution 2 -

res.status(403).json(
        {
            'success': false,
            'result': 'forbidden'
        }
    )
