How to send integers in query parameters in nodejs Express service

I have a nodejs express web server running on my box. I want to send a get request along with query parameters. Is there any way to find type of each query parameter like int,bool,string. The query parameters key value is not know to me. I interpret as a json object of key value pairs at server side.

You can't, as HTTP has no notion of types: everything is a string, including querystring parameters.

What you'll need to do is to use the req.query object and manually transform the strings into integers using parseInt():

req.query.someProperty = parseInt(req.query.someProperty);

You can also try

var someProperty = (+req.query.someProperty);

This worked for me!
