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

try creating query object, like:

//generate query object based on availability of value 
var query = {};
if( your_variable !== "" ) {
    query["some_key"] = your_variable;
}
if( your_second_variable !== "" ) {
    query["some_other_key"] = your_second_variable;
}
mongoose.model('customers').find(query, function(err, c) {
    //do something
});
