Clerk.js 2 is built to make the integration of Clerk.io onto any store frontend fast and enjoyable for developers.
Clerk.js 2 does all the heavy lifting, such as making network requests, gracefully handling errors, rendering into the DOM and applying click- and behavioural-tracking out of the box.
Clerk.js 2 should be embedded in every page of the store in the top of the page, in <head>..
You can get your tracking code for each of your stores at my.clerk.io under Settings -> Tracking Code
