How to Fix the TypeError: Cannot read property '$get' of undefined in Nuxt.js Fetch Hook

If you're working with Nuxt.js and you've encountered the error message TypeError: Cannot read property '$get' of undefined while using the Fetch hook, you're not alone. This issue can arise due to a missing dependency that you're attempting to use in your data fetching function. In this guide, we'll walk you through the solution step-by-step to ensure your Nuxt.js application runs smoothly.

Understanding the Problem

The Fetch hook in Nuxt.js is a powerful feature that allows you to fetch data asynchronously before the component is rendered. However, if the required modules are not installed or configured correctly, you might end up seeing errors like the one mentioned. This particular error indicates that the $http property is undefined when you’re trying to call $get method on it.

Step-by-Step Solution

Step 1: Install the @ nuxt/http Module

The first step in resolving this issue is to ensure that you have the @ nuxt/http module installed in your Nuxt application. You can install it using npm with the following command:

Open the nuxt.config.js file in the root of your Nuxt.js project.

Modify it to include the http module as follows:

This modification ensures that when you call the $get method, it's being called on a defined $http instance, which should resolve the error.

Conclusion

By following these steps, you should be able to eliminate the TypeError: Cannot read property '$get' of undefined error from your Nuxt.js application. Installing and properly configuring the @ nuxt/http module is crucial when working with data fetching in your components. Always ensure that any dependencies are accounted for in your project to prevent such issues down the line. Happy coding!
