Working with a node server, I've set up a client-server model, meaning the client connects to "localhost" and express generates a response based on certain logic. While I'm able to send a JSON object through the response, I'm unsure of how to access this JSON object in my client-side script. Can anyone guide me on this? Still learning here!
server:
app.get("/", function(request,response){
response.json({ username: 'example' })
})
When using Vanilla JS, there are several options available for handling data retrieval, such as the Fetch API, XMLHttpRequest, and Ajax.
1. Fetch API :
fetch('http://yourapiendpoint.com/')
.then(response => console.log(response));
2. XMLHttpRequest :
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
console.log(xhttp.responseText);
}
};
xhttp.open("GET", "http://yourapiendpoint.com/", true);
xhttp.send();
3. Ajax :
$.get("http://yourapiendpoint.com/", function(data, status){
console.log(data);
});
You can substitute the
