从服务器获取对象的请求

Question

I'm using vanilla Javascript with Node (HTTP) for server side and XMLHttpRequest for client side. Not sure how i could send an object that i've read on the server to the client.

For example i've this server code, to read the data and store it on data array to send later to the client:

            data = []
            fs.readFile("./client.json", function(err, jsonData){
                if(err){
                    throw err;
                }else{
                    data.push(JSON.parse(jsonData));
                }
            });

Now i'm kinda lost of how client side would be to GET the data array. I've tried this but couldn't get any

let xhttp = new XMLHttpRequest();

    xhttp.open("GET", "http://localhost:3000/data", true);
    xhttp.send(null);

I don't want to use Fetch nor Express. using HTTP for learning purpose.

Use URL module to parse request URL to write logic for individual endpoints.

In your case the endpoint would be /data . Here you can return the data array as response.
