That's because its hosted on a web-server, you need to send a HTTP GET to fetch it locally.

Install the axios package and issue a HTTP GET request to fetch the remote resource from the web-server.

npm install --save axios

Here's a program of the general idea

const fs = require('fs');
const axios = require('axios');
const { promisify } = require('util');

const writeFilePromise = promisify(fs.writeFile);

(async () => {
  const url = 'http://techslides.com/demos/sample-videos/small.mp4';
  const response = await axios.get(url);
  if (response.data) {
    await writeFilePromise('small.mp4', response.data);
  }
})();

fs.statSync() can take a URL, but ONLY if that URL is a file:// URL.

It is not clear what you would want to do if the argument was actually an http:// URL. You could check to see if it was not a file URL and then attempt to fetch the contents of the URL to see if it exists using a library such as got().

But, fetching data from another server with http will not be synchronous so you will have to change the design of your function to return a promise instead of a synchronous API.
