Resolving Multiple useFetch Calls Error in Nuxt 3: A Step-by-Step Guide

In this post, we’ll dive into the specific error you might face and guide you through an effective solution that allows you to make multiple API calls simultaneously without running into conflicts.

The Problem

Imagine you have a Vue component in a Nuxt 3 application, and you want to fetch lecture details and student check-in status from your API. Initially, everything works fine with a single useFetch call:

However, when you introduce another useFetch call:

Running the code may trigger the following error:

This error arises because the Nuxt framework does not allow composables to be called asynchronously in a way that one operation blocks another.

Understanding the Solution

The key to resolving this issue lies in how you manage asynchronous calls. You must ensure that the useFetch calls do not await one another in a way that can cause this conflict.

Step-By-Step Approach

Implement the Solution:

Explanation of the Code:

Handling Results: The results from both fetch functions are destructured in the .then() block.

Error Handling: Any errors that arise from either of the calls are caught and logged, helping with easier debugging.

Conclusion

If you encounter the challenge of multiple API requests in your Nuxt applications, remember this approach, and you’ll be on your way to a smoother development experience.

Happy coding!
