It can be done in two steps:
document.currentScript
.document.currentScript
property returns the <script>
tag of the currently processed JS file. So having that knowledge we can easily get current script's URL from src
property of document.currentScript
:
const jsFileUrl = document.currentScript.src;
jsFileUrl
to get the domain name:To do this, I like using URL
constructor (https://developer.mozilla.org/en-US/docs/Web/API/URL/URL). We can pass an URL to that constructor and get an object representing given URL with a bunch of useful properties:
const url = new URL(jsFileUrl);
console.log(url.host);
console.log(url.origin);
console.log(url.protocol);
// etc...
So if we put it as a one-liner, it would look like:
const getSrcOrigin = () => new URL(document.currentScript.src).origin;
Hope this helps!
