ReferenceError: fetch is not defined error occurs when trying to “use the fetch() function in a Node.js environment, but fetch is not natively available in Node.js.”
In browsers, the fetch API provides a simple way to make network requests. But in Node.js, it is not available.
Reproduce the error
How to fix the error
To fix the fetch is not defined error in Node.js, use libraries like “axios”, “node-fetch”, or the “built-in http and https modules to make HTTP requests.”
To use the fetch function in Node.js, you can install the node-fetch package:
npm install node-fetch
Now, we can use the fetch() method in Node.js.
If you are using ES6 imports:
import fetch from 'node-fetch';
This will give you a fetch() function in Node.js that works similarly to the browser’s fetch API.
