Migrate to the new Storefront UI

Spree 4.1 comes with a completely new mobile-first ultra-fast Storefront powered by Turbolinks.

To replace your current frontend with the new Spree UI follow these steps:

  1. In your project root directory run:

     rails g spree:frontend:copy_storefront
    

    WARNING this will overwrite your current project templates, it’s required for the new UI, so if you’ll be asked by the generator what to do please choose A to proceed

  2. Next, you will need to copy over two files:

  3. If you overwrote any spree_frontend controllers you will need to either remove your local copies or move your custom logic to decorators

  4. The same goes for helpers

  5. You will also need to remove this line:

     //= require spree/frontend/spree_auth
    

    from vendor/assets/javascripts/spree/frontend.all.js file

Stay at the current UI

If you wish to not move to the new Storefront UI it’s still an option. Just proceed with the steps described below.

  1. Copy over all views from Spree 4.0

    Copy overviews from: https://github.com/spree/spree/tree/4-0-stable/frontend/app/views to your application views directory: app/views

  2. Copy over all Stylesheets from Spree 4.0

    Copy over stylesheets from: https://github.com/spree/spree/tree/4-0-stable/frontend/app/assets/stylesheets to app/stylesheets
