How to receive a JSON file from a glitch-hello-website to a node.js app

I couldn’t find the part that I was supposed to use on the node.js side

“Part” isn’t entirely specific, but there are sort of two things to put on the node.js side. The first is the “npm package” node-fetch, which you kind of find by knowing the package name. That package name is “node-fetch,” so hooray, there it is. BTW in case you haven’t tried adding an npm package on Glitch before, they have a tutorial on how to do it: How do I add an npm module or package to my project? - Glitch Support

The second thing to put on the node.js side is a piece of code that uses the package. I suggested that you try is to get sample piece of code from the node-fetch readme. It’s a little spread out throughout the documentation, but it’s here node-fetch - npm

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

and here node-fetch - npm

    .then(res => res.json())
    .then(json => console.log(json));

I hope this helps on what it is to find the “parts” that you’d need to try this out.

There’s still a lot for you to do though. For one, see if you can figure out where to add this code in your project so that it runs.
