I am generating a PDF on the NodeJS server and when it is ready I want it to be sent to the client and downloaded, all through a GET request. The file will be generated on the server, stored in a specific address and then returned in the GET request, or it can also be sent by clicking on a link. All I need is to figure out how to send this PDF to the client.

javascript pdf node.js

Assuming you are using the express server, use res.download

It downloads the file in the path as a attachment :

var express = require('express');
var router = express.Router();    

router.get('/download', function (req, res, next) {
    var filePath = "/Users/meuuser/PDFs"; //caminho do arquivo completo
    var fileName = "report.pdf"; // O nome padrão que o browser vai usar pra fazer download

    res.download(filePath, fileName);    
});

Note: There is res.attachment , but if you use it, it will set the header Content-Disposition to "attachment" and this will make the browser understand that it should be seen as an attachment, not a webpage When you use res.download , it transfers the file as an attachment, then usually browsers will consider downloading the file.
