I'm writing a REST API and I have a route defined as follows:

router.get("/objects/:id?/:val1?/:val2?", getObject);

I'm sending the following get request from Postman: 

http://localhost:8000/objects?val1=5&val2=6

I'm using express validator like this in getObject:

req.check("val1", "Invalid param: val1").notEmpty().isInt();

Even though I'm passing in numbers, when I it's only picking them up as strings. When I print to console using JSON.stringify(req.query), they also show as string instead of numbers. How would I go about fixing this? Would I have to cast the parameters as numbers? If I did, express validator wouldn't be as useful since it could only check for whether the parameter was passed in.

Everything passed in URL even as query string will be received as string at receiver's end. You will have to explicitly use:

Number(val1)

or

parseInt(val1)

to convert it to number.
