Scaffolder Frontend

This is the React frontend for the default Backstage software templates. This package supplies interfaces related to showing available templates in the Backstage catalog and the workflow to create software using those templates.

Installation

This @backstage/plugin-scaffolder package comes installed by default in any Backstage application created with npx @backstage/create-app, so installation is not usually required.

To check if you already have the package, look under packages/app/package.json, in the dependencies block, for @backstage/plugin-scaffolder. The instructions below walk through restoring the plugin, if you previously removed it.

Install the package

# From your Backstage root directory
yarn add --cwd packages/app @backstage/plugin-scaffolder

Add the plugin to your packages/app

Add the root page that the scaffolder plugin provides to your app. You can choose any path for the route, but we recommend the following:

// packages/app/src/App.tsx
+import { ScaffolderPage } from '@backstage/plugin-scaffolder';


<FlatRoutes>
  <Route path="/catalog" element={<CatalogIndexPage />} />
  <Route path="/catalog/:namespace/:kind/:name" element={<CatalogEntityPage />}>
    {entityPage}
  </Route>
+  <Route path="/create" element={<ScaffolderPage />} />;
  ...
</FlatRoutes>

The scaffolder plugin also has one external route that needs to be bound for it to function: the registerComponent route which should link to the page where the user can register existing software component. In a typical setup, the register component route will be linked to the catalog-import plugin's import page:

// packages/app/src/App.tsx
+import { scaffolderPlugin } from '@backstage/plugin-scaffolder';
+import { catalogImportPlugin } from '@backstage/plugin-catalog-import';

const app = createApp({
  // ...
  bindRoutes({ bind }) {
+    bind(scaffolderPlugin.externalRoutes, {
+      registerComponent: catalogImportPlugin.routes.importPage,
+    });
  },
});

You may also want to add a link to the scaffolder page to your application sidebar:

// packages/app/src/components/Root/Root.tsx
+import CreateComponentIcon from '@material-ui/icons/AddCircleOutline';

export const Root = ({ children }: PropsWithChildren<{}>) => (
  <SidebarPage>
    <Sidebar>
+      <SidebarItem icon={CreateComponentIcon} to="create" text="Create..." />;
      ...
    </Sidebar>

Troubleshooting

If you encounter the issue of closing EventStream which auto-updates logs during task execution, you can enable long polling. To do so, update your packages/app/src/apis.ts file to register a ScaffolderClient with the useLongPollingLogs set to true. By default, it is false.

import {
  createApiFactory,
  discoveryApiRef,
  fetchApiRef,
  identityApiRef,
} from '@backstage/core-plugin-api';
import {
  scaffolderApiRef,
  ScaffolderClient,
} from '@backstage/plugin-scaffolder';

export const apis: AnyApiFactory[] = [
  createApiFactory({
    api: scaffolderApiRef,
    deps: {
      discoveryApi: discoveryApiRef,
      identityApi: identityApiRef,
      scmIntegrationsApi: scmIntegrationsApiRef,
      fetchApi: fetchApiRef,
    },
    factory: ({ scmIntegrationsApi, discoveryApi, identityApi, fetchApi }) =>
      new ScaffolderClient({
        discoveryApi,
        identityApi,
        scmIntegrationsApi,
        fetchApi,
        useLongPollingLogs: true,
      }),
  }),
  // ... other factories

This replaces the default implementation of the scaffolderApiRef.
