            "name": "control-panel",
            "srv": true,
            "authSource": "admin",
            "retryWrites": true,
            "w": "majority"
        }
    }
}

Creating model

1. Create file ModelName.js in models/mongo directory
2. Fill model file.
3. Done!

Example:

module.exports = {
    // Any mongoose schema constuctions allowed
    field: { type: String, required: true },
    otherField: { type: Number, default: Date.now() + 1000 * 60 },

    // Second argument of schema constuctor
    // new Schema(..., $options)
    $options: { strict: false },

    // Register default auto-increment field "uid"
    $increment: 'uid',
    // Same with options
    $increment: { field: 'uid', start: 1 },

    // Mongoose virtual fields
    $virtuals: {
        timestamp: {
            // schema.virtual('timestamp').get(<this function>)
            get () {
                // `document.timestamp` will return creation time in ms
                return this._id.getTimestamp().getTime();
            }
        }
    }
};
