Site Plugins

What are site plugins?

A site plugin can contain one or more extensions for Crafter CMS in a single package. These extensions can:

  • Extend Crafter Studio (authoring)

    • Add Studio authoring widgets that drive the Sidebar and other UI elements

    • Add new Form Engine extensions including data sources and components

    • Add server-side code and services that drive the Studio UI extensions

  • Extend Crafter Engine and the site/web application (delivery)

    • Add new content types along with their Groovy controllers and FreeMarker templates

    • Add REST APIs and/or server-side code

    • Add 3rd party integrations to your web app

How do I make my own site plugin?

A site plugin consist of a group of files that are copied to the site repository when installed, to create your own site plugin you only need to copy the files following this structure:

  • craftercms-plugin.yaml: the plugin descriptor, see Crafter CMS Plugin Descriptor for details

  • authoring: contains all files related to Crafter Studio extensions

    • content-types

      • component: contains configuration files for components

      • page: contains configuration files for pages

    • js: contains files for Studio UI plugins, see Crafter Studio Plugins for details

    • scripts

      • classes: contains Groovy classes

      • rest: contains REST Groovy scripts

  • delivery: contains all files related to Crafter Engine extensions

    • templates: contains Freemarker templates

    • static-assets: contains binary files

    • scripts

      • classes: contains Groovy classes

      • components: contains Groovy scripts for components

      • controllers: contains Groovy controllers

      • filters: contains Groovy filters

      • pages: contains Groovy scripts for pages

      • rest: contains Groovy REST scripts

An easy way to develop new plugins is to start with an empty site and when all the files are ready copy them to a new repository following the given structure. However all references should be updated to match the final destination of the file:
