The Best Practices for Updating Different Properties in Node.js APIs

Building an effective API requires a solid understanding of how to handle data updates, especially when users provide input that affects properties of your resources. In this guide, we will explore the best way to update user properties in a Node.js API, focusing on TypeORM and the Restify framework. Let's dive into the common challenges faced when updating resource properties and how to implement a robust solution.

The Problem: Safely Updating User Properties

When developing an API with Restify and managing user entities with TypeORM, a common challenge arises: ensuring that important properties of a user, such as id, chat_id, project_id, and deleted, are not overwritten by user input. Developers often struggle with finding a balance between updating necessary properties and preserving critical ones.

Current Approach

You may have implemented an approach similar to the following:

In this code snippet, the update method receives the user input, along with the user ID. The service layer may look like this:

While this method uses Object.assign to selectively merge user data, there is a more efficient and cleaner way to handle property updates in TypeORM.

The Solution: Utilizing TypeORM's Update Method

Partial Updates Made Easy

Instead of manually preventing certain properties from being updated, TypeORM offers a built-in method that can greatly simplify this process. You can use the update method to partially update user records with just the properties you want to change. Here's how:

With this approach, you can precisely define which properties to update without worrying about unintentionally overwriting important fields. It's straightforward and leverages TypeORM's strengths to effectively manage database interactions.

Creating a New User with Modified Properties

If your goal is to create a new record based on an existing user, simply cloning and adjusting the id property will help you accomplish this. Here’s how:

Deep Clone the User Object: Create a copy of the user object to ensure it has a new reference.

Remove the id Field: Eliminate the id field from the cloned object to prepare for insertion as a new record.

Here's the implementation:

By following this procedure, you can efficiently create unique records while avoiding potential conflicts with existing users.

Conclusion

Updating properties in a Node.js API built with TypeORM doesn't have to be cumbersome. By employing the update method of TypeORM, you can handle partial updates cleanly and efficiently. Furthermore, by understanding how to create new records from existing ones, you’ll enhance the overall functionality of your API.

By implementing these strategies, you’ll ensure that your API remains robust, flexible, and secure against unintended data overwrites. Happy coding!
