Upgrading to Clerk.js 2 on Prestashop

See how to get the flexible Clerk.js 2 setup on your webshop.

Clerk.js 2 is a faster and much more flexible version of our JavaScript library that makes installing Clerk.io on any webshop a breeze.

However, since the two versions work slightly differently, you need to follow these steps to successfully upgrade.

The two main differences in Clerk.js 2 is that the Designs in my.clerk.io use the Liquid templating language, but they can also easily be created using the Design Editor.

Step 1: Converting Designs

Since Clerk.js 2 has a different approach Designs, you need to create new ones.

You can create your Clerk.js 2 Designs in one of two ways:

1.1 Start by going to my.clerk.io -> Recommendations / Search -> Designs and click New Design:

1.2 On the following screen, give your Design a Name (we recommend adding " V2" so its obvious that you are using Clerk.js2).

1.3. Choose Design Type.

1.4. When you are done, click Create Design.

1.5. In the Design Editor, click any of the existing elements like the name, image, button, etc. to edit it, or drag-and-drop new elements to the Design to add more information about products.

1.6. Click Save Design when you are done, and go to Step 2 in the guide.

1.7. Lastly, go to Recommendations / Search -> Content and change your Clerk.io Content to use your new Design.

1.8. Click Update Content. This will temporarily cause them to not show up on your webshop until you are done with

Step 2. Choose the new Design for all Content that should be updated.
