Programmatically build dynamic query with Mongoose

Question

I\'m trying to build a search from input received from a form.

router.get(\'/data\', function(req, res) {
    var firstName=req.body.firstName,
    lastName         


        

Answer 1

To avoid checking each parameter independently you can loop through them.

var query = {};
for(var key in req.body){ //could also be req.query and req.params
  req.body[key] !== "" ? query[key] = req.body[key] : null;
}

mongoose.model('customers').find(query, function(err, customers){

})
