Example 1: mongoose find() example

// find all documents
await MyModel.find({});

// find all documents named john and at least 18
await MyModel.find({ name: 'john', age: { $gte: 18 } }).exec();

// executes, passing results to callback
MyModel.find({ name: 'john', age: { $gte: 18 }}, function (err, docs) {});

// executes, name LIKE john and only selecting the "name" and "friends" fields
await MyModel.find({ name: /john/i }, 'name friends').exec();

// passing options
await MyModel.find({ name: /john/i }, null, { skip: 10 }).exec();

Example 2: mongoose where

exports.generateList = function (req, res) {
    subcategories
            .find({})//grabs all subcategoris
            .where('categoryId').ne([])//filter out the ones that don't have a category
            .populate('categoryId')
            .where('active').equals(true)
            .where('display').equals(true)
            .where('categoryId.active').equals(true)
            .where('display').in('categoryId').equals(true)
            .exec(function (err, data) {
            if (err) {
                console.log(err);
                console.log('error returned');
                res.send(500, { error: 'Failed insert' });
            }

            if (!data) {
                res.send(403, { error: 'Authentication Failed' });
            }

            res.send(200, data);
            console.log('success generate List');
        });
    };
