How to Retrieve the Id After Creating Data in React (Next.js) with Apollo

Creating an eCommerce website is an exciting challenge, particularly when it comes to implementing comprehensive order processing functionalities. One common question that arises is: How can I get the Id of an order immediately after it is created? This is crucial for redirecting users to their order details pages right after a purchase.

In this guide, we will break down the process, ensuring you know how to set up your checkout functionality seamlessly using React, Next.js, and Apollo. Let’s dive into the solution!

The Problem

You're developing an eCommerce platform where users can place orders. After the order form is submitted, you aim to retrieve the newly created order's Id so that you can redirect users to the order details page (e.g., orders/[id]). However, you've encountered an issue where you receive an undefined response for the order Id immediately after the submission.

This common challenge can stem from improper handling of the promise returned during the order creation process.

The Solution: Correcting Your Promise Handling

To resolve this problem, you'll need to ensure that you are correctly retrieving and using the response from your createOrder mutation. Here’s a closer look at the adjustments you need to make to your existing code.

Step-by-Step Code Adjustment

In your original implementation, you are missing the return for the res parameter of your promise, which is critical for obtaining the correct data. The updated section of your code should look like this:

Key Changes Explained

Return the Response: By updating the .then() function to accept res as a parameter, you are directly accessing the response returned from your mutation.

Extracting the Order ID: Now, through destructuring, you can pull the createOrder object from the response, which contains the id you need for redirection.

Logging the ID: When you log the id, it should now correctly reflect the new order that was created.

Conclusion

Implementing a solution to retrieve the Id after creating data in a React (Next.js) application with Apollo mutations is vital for enhancing user experience. By ensuring that your promise is correctly handled, you can avoid common pitfalls like receiving undefined values.

With proper coding practices and logic, redirecting your users to the order confirmation page becomes seamless and effective. Feel free to adapt the example above to suit your application's requirements, and happy coding!
