Using modifyClass to change core behavior

pangbo · March 4, 2026, 7:13am

The example for api.modifyClass in plugin-api.gjs still uses legacy syntax. Perhaps it requires updating?

frontend/discourse/app/lib/plugin-api.gjs

          /**
           * Allows you to overwrite or extend methods in a class.
           *
           * You should add a `pluginId` property to identify your plugin
           * to help Discourse reload classes properly.
           *
           * For example:
           *
           * ```
           * api.modifyClass('controller:composer', {
           *   pluginId: 'my-plugin',
           *   actions: {
           *     newActionHere() { }
           *   }
           * });
           * ```
           **/
          modifyClass(resolverName, changes, opts) {
