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(status) instead

I am not sending a Status, my code is

app.get('/runSyncTest' , function(request, response){  

var nodes = request.query.nodes;
var edges = request.query.edges;
if (edges == "" ){
    edges = []
}

userStory.userStory(nodes,edges);
connection.query('SELECT MAX(id) as id FROM report ', function(err,results, fields) {
                idTest = results[0].id
                response.send (idTest)
});

});

Solution 1

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

Solution 2

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

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

Solution 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));

Solution 4

Its Deprecated, Express 5 No Longer Supports The Signature Like -

res.json(200, {
   result: result
});

Instead, use a below method, Means you only need to change the format of sending responses.

res.status(statusCode).json(result);

Example -

res.status(200).json({'success' : true, 'result': result})

Solution 5

Use like this,

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