NuxtJS is a powerful framework for building server-side rendered (SSR) and static websites using Vue.js.
While NuxtJS provides a built-in way to handle HTTP requests using the asyncData or fetch methods, it doesn't have a direct way to handle GET requests with a JSON body.
In this article, we will explore a solution to handle GET requests with a JSON body in NuxtJS.

Why handle GET requests with a JSON body?

Traditionally, GET requests are used to retrieve data from a server, and the request parameters are sent in the query string.
However, there may be cases where you want to send more complex data or sensitive information in the request body, and using a JSON payload is a common approach.
Handling GET requests with a JSON body can provide more flexibility and security in certain scenarios.

Solution: Using Axios and a Middleware

To handle GET requests with a JSON body in NuxtJS, we can leverage the Axios library and create a custom middleware.
Axios is a popular HTTP client for JavaScript, which provides an easy-to-use API for making HTTP requests.
Here are the steps to implement this solution:

Step 1: Install Axios

First, we need to install Axios by running the following command in your NuxtJS project:
npm install axios

Step 2: Create a Middleware

Next, create a new file called jsonGetMiddleware.js in the middleware directory of your NuxtJS project.
Inside this file, add the following code:
export default function ({ $axios }) { $axios.onRequest((config) => { if (config.method === 'get' && config.body) { config.method = 'post'; config.headers['Content-Type'] = 'application/json'; = JSON.stringify(config.body); } return config; }); }
This middleware intercepts all outgoing requests made by Axios and modifies the request configuration if it's a GET request with a body.
It automatically converts the GET request to a POST request and sets the appropriate headers and body payload.

Step 3: Register the Middleware

To use the middleware, we need to register it in the nuxt.config.js file.
Open the file, and in the modules.exports object, add the following code:
export default { // ... modules: [ // ... '@nuxtjs/axios', ], axios: { // ... middleware: ['jsonGetMiddleware'], }, // ... }
This configuration tells NuxtJS to use the Axios module and apply the jsonGetMiddleware middleware to all Axios requests.

Step 4: Send a GET Request with a JSON Body

Now, you can use Axios to send a GET request with a JSON body.
Here's an example:
async asyncData({ $axios }) { const response = await $axios.$get('/api/data', { body: { name: 'John', age: 30 }, }); return { data: response, }; },
In the above example, we make a GET request to /api/data with a JSON payload containing the name and age properties.
The response will be stored in the data variable.


Handling GET requests with a JSON body can be useful in certain scenarios where you need to send complex data or sensitive information.
By leveraging Axios and creating a custom middleware in NuxtJS, you can easily handle such requests.
In this article, we explored the steps to implement this solution, including installing Axios, creating a middleware, registering the middleware, and sending a GET request with a JSON body.
Remember to refer to the official documentation of Axios and NuxtJS for more details on how to use these libraries.
