Not able to send cookies using `fetch` in NextJS server side component (app router)

If you are using Next.js and encountering issues with sending cookies using the fetch function in the server-side component (app router), you’re not alone. This problem often arises due to the way Next.js handles server-side rendering and the need to pass cookies along with the request.

Fortunately, there are a couple of solutions to this problem. Let’s explore them below:

Solution 1: Using the `credentials` option

The fetch function allows you to include the credentials option, which can be set to 'include' to send cookies along with the request. This option ensures that the browser includes any relevant cookies in the request headers.

Here’s an example code snippet that demonstrates how to use the credentials option:

fetch(url, {
  method: 'GET',
  credentials: 'include'
})
  .then(response => response.json())
  .then(data => {
    // Handle the response data
  })
  .catch(error => {
    // Handle any errors
  });

Make sure to replace url with the actual URL you’re making the request to.

Solution 2: Using the `node-fetch` package

If Solution 1 doesn’t work for you, you can try using the node-fetch package instead of the built-in fetch function. This package provides a more compatible implementation of the fetch function for server-side environments.

First, install the node-fetch package by running the following command:

npm install node-fetch

Then, import the package and use it in your code like this:

const fetch = require('node-fetch');

fetch(url, {
  method: 'GET',
  headers: {
    'Cookie': 'your-cookie-value'
  }
})
  .then(response => response.json())
  .then(data => {
    // Handle the response data
  })
  .catch(error => {
    // Handle any errors
  });

Replace url with the actual URL you’re making the request to, and your-cookie-value with the value of the cookie you want to send.

With these solutions, you should be able to send cookies using fetch in Next.js server-side components without any issues. Remember to choose the solution that works best for your specific use case.

Happy coding!
