How to find items using regex in Mongoose

Question

In Mongoose doc I didn't find an equivalent for $regex of MongoDb. Can you provide a simple Mongoose find() with a regex expression?

Answer 1

mongoose doc for find.

mongodb doc for regex.

var Person = mongoose.model('Person', yourSchema);
// find each person with a name contains 'Ghost'
Person.findOne({ "name" : { $regex: /Ghost/, $options: 'i' } },
    function (err, person) {
        if (err) return handleError(err);
        console.log('%s %s is a %s.', person.name.first, person.name.last, person.occupation);
});

Note the first argument we pass to mongoose.findOne function. { "name": { $regex: /Ghost/, $options: 'i' } }. "name" is the field of the document you are searching. "Ghost" is the regular expression. "i" is for case insensitive match. Hope this will help you.
