Im a beginner with node.js so bear with me please :D
Simple task: I use express and I want to send an array, lets say ["item1", "item2"] from a node server to a client that calls the server with a get method. When I tried this, I stumbled upon the CORS error.
I also thought about doing a this through a post:
-client:
$(document).ready(function () {
$(".testButton").click(function (e)
e.preventDefault();
$.ajax(
url: "http://localhost:3000/test_post",
type: "post",
data: "sent",
success: function ()
);
);
-server:
app.post('/Quiz_post', function (req, res)
res.send(["item1", "item2"]);
);
But this also doesnt work. Now I am trying to use cross-fetch client side. Could you please guide me a bit? Thanks!

Add this code in ur app.js to enable CORS.
npm i cors in the project 1st
var cors = require('cors');
var app= express(); //After this line of code add the code below
app.use(cors());

Thanks. This removed the CORS err. Now I am figuring out the next part: sending the actual array/json form the server and using it on the client.

To send JSON data back just res.json(Object/array). You can test your server api by using postman
