Get API or File Size
This code sample will allow you to retrieve the size of a file or API response without actually downloading it (server needs to provide Content-Length header).
function getApiSize(url) { var req = new XMLHttpRequest(); req.open("HEAD", url, false); req.send(null); console.log(req.getResponseHeader('Content-Length')); }
Directions:
- Call getApiSize(url); and you will see the size in your console.
