{{asset}}

If your theme was migrated to the new Customize Design experience in 2018, you might have used {{asset "name" cdn="legacy"}} in your theme. This would render a link to the previous asset CDN for backwards compatibility. The cdn attribute is no longer supported and will be ignored.

Removed object properties/helpers

{{user_info}}

This helper is no longer available in the header template. The following helpers are now available to build a corresponding menu: {{user_avatar}}, {{user_name}}, {{my_profile}}, {{change_password}}. You can find an example of the re-implemented dropdown in the Copenhagen Theme's header template

{{unsubscribe}}

This helper is no longer available in the subscription object. The {{subscribe}} helper now also allows to unsubscribe when content is already subscribed. The {{following}} attribute outputs the types of content being followed.

Performance improvements and removed libraries

The theme's script.js file is now loaded at the end of the page body for improved page performance. In addition, the libraries listed in this section are no longer present in Templating API v2. If you need one or more of these libraries to customize your theme, you can still add them as theme assets. See Using your own theme assets for Help Center in Guide Help.

jQuery

jQuery is no longer as ubiquitous as it once was so it's no longer included by default. The Copenhagen theme is now built with plain vanilla Javascript.

If your theme still requires jQuery, you can import it in your document head template. You can either add it as an asset to your theme or load it from an external source. See more information in Importing or upgrading jQuery.

Templating API v1 was using jQuery version 1.9.1. This version is no longer supported and you should consider upgrading. You can find multiple versions of jQuery at https://cdnjs.com/libraries/jquery/.

If you were previously using jQuery to make Zendesk API requests that require an authenticity token (also known as a CSRF token), you now need to fetch the token as part of your JavaScript code.

Example:

$.ajax({
    url: "/api/v2/users/me",
    dataType: "json"
  })
  .done(function(data) {
    authenticityToken = data.user.authenticity_token;

    // Your request goes here
    $.ajax({
      url: "/api/v2/requests",
      method: "POST",
      dataType: "json",
      headers: {
        "X-CSRF-Token": authenticityToken
      },
      data: {
        "request": {
          "subject": "Help!",
          "comment": {
            "body": "My printer is on fire!"
          }
        }
      }
    }).done(function(data) {
      console.log(data)
    })
  });
moment.js

Although moment.js was not a documented API, it was available in the window object and was used by theme developers.

This is no longer possible in Templating API v2. Consider importing it in your theme if it is required.

Templating API v1 was using moment.js version 2.4.0.

normalize.css

Normalize.css is a small CSS library that provides cross-browser consistency in the default styling of HTML elements.

This is no longer available in Templating API v2. Consider importing it in your theme if it is required.

Templating API v1 was using normalize.css version 3.0.0.

entypo

Entypo is a popular icon font library which was included by default and used in the Copenhagen theme.

The theme was migrated to use inline SVGs for better page load performance and improved accessibility.

dropdowns

Help Center would inject dropdown functionality to the theme. This functionality is now implemented through the Copenhagen Theme's style and script files.

Other updates

  • The Help Center's mobile-specific layout, originally deprecated in 2017, has been removed in Templating API v2. Consider updating your theme to have a responsive layout if your users are accessing the Help Center from mobile.
  • Improved template validation - helpers cannot be used within conditional expressions
