How to Fetch and Update MongoDB Records with Mongoose in One Request?

Understanding Mongoose

Mongoose is a powerful library that allows you to model your data in a schema-based form. It pairs beautifully with MongoDB and enables seamless CRUD (Create, Read, Update, Delete) operations.

Fetch and Update in One Request

The combination of fetching and updating records is frequent. For example, you may need to retrieve a user record and update their information. Doing this in two separate operations can be inefficient, so Mongoose offers a way to combine these steps.

Using findOneAndUpdate

Mongoose provides the findOneAndUpdate method, which finds a record based on specified criteria and updates it in a single atomic operation. This method is essential when you need to ensure the integrity and consistency of your data during concurrent operations.

Example Code

Explanation

Criteria: { _id: userId } specifies the unique identifier of the user you want to update.

Update Data: { $set: updateData } contains the fields you want to update.

Options: { new: true } ensures the method returns the updated document instead of the original one.

Additional Options

Mongoose's findOneAndUpdate method accepts several useful options:

new: If set to true, it returns the modified document rather than the original.

upsert: If set to true, it creates a new document if no document matches the criteria.

runValidators: If set to true, it runs schema validation during the update process.

These options allow you to fine-tune the behavior of the update operation according to your needs.

Conclusion

By leveraging Mongoose's capabilities, you can handle complex data operations with ease and confidence. Try incorporating findOneAndUpdate in your next project to see the difference!
