第 8 章 Configuring a floating action button in Red Hat Developer Hub

You can use the floating action button plugin to configure any action as a floating button in the Developer Hub instance. The floating action button plugin is enabled by default. You can also configure floating action buttons to display as submenu options within the main floating action button by assigning the floating action buttons to the same slot field of your dynamic-plugins.yaml file.

You can configure the floating action button as a dynamic plugin to perform actions or open an internal or external link.

Prerequisties

You must have sufficient permissions as a platform engineer.

Procedure

To configure a floating action button as a dynamic plugin, complete any of the following tasks:

  • Specify the global.floatingactionbutton/config mount point in your app-config-dynamic.yaml file. For example: 

    - package: ./dynamic-plugins/dist/red-hat-developer-hub-backstage-plugin-bulk-import
  disabled: false
  pluginConfig:
    dynamicPlugins:
      frontend:
        red-hat-developer-hub.backstage-plugin-bulk-import:
          # Start of the floating action button configuration
          mountPoints:
            - mountPoint: global.floatingactionbutton/config
              importName: BulkImportPage
              config:
                slot: 'page-end'
                icon: <svg xmlns="http://www.w3.org/2000/svg" enable-background="new 0 0 24 24" height="24px" viewBox="0 0 24 24" width="24px" fill="#e8eaed"><g><rect fill="none" height="24" width="24"/></g><g><path d="M11,7L9.6,8.4l2.6,2.6H2v2h10.2l-2.6,2.6L11,17l5-5L11,7z M20,19h-8v2h8c1.1,0,2-0.9,2-2V5c0-1.1-0.9-2-2-2h-8v2h8V19z"/></g></svg>
                label: 'Bulk import'
                toolTip: 'Register multiple repositories in bulk'
                to: /bulk-import/repositories
          # End of the floating action button configuration
          appIcons:
            - name: bulkImportIcon
              importName: BulkImportIcon
          dynamicRoutes:
            - path: /bulk-import/repositories
              importName: BulkImportPage
              menuItem:
                icon: bulkImportIcon
                text: Bulk import
    frontend:mountPoints:importName
    (Required) The import name with an associated component to the mount point.
    frontend:mountPoints:importName:icon
    Use the svg value to display a black BulkImportPage icon.

  • To configure an action as a floating action button that opens an external link, specify the global.floatingactionbutton/config mount point in your dynamic-plugins.yaml file within the backstage-plugin-global-floating-action-button plugin. For example: 

    - package: ./dynamic-plugins/dist/red-hat-developer-hub-backstage-plugin-global-floating-action-button
  disabled: false
  pluginConfig:
    dynamicPlugins:
      frontend:
        red-hat-developer-hub.backstage-plugin-global-floating-action-button:
          mountPoints:
              - mountPoint: application/listener
                importName: DynamicGlobalFloatingActionButton
              - mountPoint: global.floatingactionbutton/config
                importName: NullComponent
                config:
                  icon: '<svg viewBox="0 0 250 300" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="xMidYMid"><path d="M200.134 0l55.555 117.514-55.555 117.518h-47.295l55.555-117.518L152.84 0h47.295zM110.08 99.836l20.056-38.092-2.29-8.868L102.847 0H55.552l48.647 102.898 5.881-3.062zm17.766 74.433l-17.333-39.034-6.314-3.101-48.647 102.898h47.295l25-52.88v-7.883z" fill="#40B4E5"/><path d="M152.842 235.032L97.287 117.514 152.842 0h47.295l-55.555 117.514 55.555 117.518h-47.295zm-97.287 0L0 117.514 55.555 0h47.296L47.295 117.514l55.556 117.518H55.555z" fill="#003764"/></svg>'

                config:
                  icon: github

    frontend:mountPoints:importName
    (Required) The import name with an associated component to the mount point.
    frontend:mountPoints:importName:icon
    Use the svg value to display the Quay icon.

  • To configure a floating action button that contains a submenu, define the global.floatingactionbutton/config mount point in the same slot field in your dynamic-plugins.yaml file for multiple actions. The default slot is page-end when not specified. For example: 

    - package: ./dynamic-plugins/dist/red-hat-developer-hub-backstage-plugin-bulk-import
  disabled: false
  pluginConfig:
    dynamicPlugins:
      frontend:
        red-hat-developer-hub.backstage-plugin-bulk-import:
          # Start of fab config
          mountPoints:
            - mountPoint: global.floatingactionbutton/config
              importName: BulkImportPage
              config:
                slot: 'page-end'
                icon: <svg xmlns="http://www.w3.org/2000/svg" enable-background="new 0 0 24 24" height="24px" viewBox="0 0 24 24" width="24px" fill="#e8eaed"><g><rect fill="none" height="24" width="24"/></g><g><path d="M11,7L9.6,8.4l2.6,2.6H2v2h10.2l-2.6,2.6L11,17l5-5L11,7z M20,19h-8v2h8c1.1,0,2-0.9,2-2V5c0-1.1-0.9-2-2-2h-8v2h8V19z"/></g></svg>

          appIcons:

  • To configure a floating action button to display only on specific pages, configure the global.floatingactionbutton/config mount point in the backstage-plugin-global-floating-action-button plugin and set the visibleOnPaths property as shown in the following example: 

    - package: ./dynamic-plugins/dist/red-hat-developer-hub-backstage-plugin-bulk-import
  disabled: false
  pluginConfig:
    dynamicPlugins:

  • To hide a floating action button on specific pages, configure the global.floatingactionbutton/config mount point in the backstage-plugin-global-floating-action-button plugin and set the excludeOnPaths property as shown in the following example:
