Update serverlessops-catalog plugin for new frontend system by Copilot · Pull Request #16 · ServerlessOpsIO/backstage-app

Copilot · 2026-06-30T23:36:12Z

Migrate serverlessops-catalog to the frontend plugin entrypoint

move serverlessops-catalog to createFrontendPlugin / PageBlueprint wiring at the package root
update the app to consume @internal/backstage-plugin-serverlessops-catalog from the root entrypoint
switch the plugin dev app to @backstage/frontend-dev-utils
mount the tabbed catalog and directory pages under /serverlessops-catalog/catalog and /serverlessops-catalog/directory to avoid conflicts with the default catalog routes
align the package metadata and plugin export tests with the current frontend-plugin surface

Example of the intended consumption pattern after this change:

import serverlessOpsCatalogPlugin from '@internal/backstage-plugin-serverlessops-catalog';

export default createApp({
  features: [serverlessOpsCatalogPlugin],
});

NOTE: This comment was ediyed by @tmclaugh after additional work was performed

…system - Replace createPlugin/createRoutableExtension (old system) with createFrontendPlugin/PageBlueprint.make from @backstage/frontend-plugin-api - Replace createRouteRef per page (catalogIndexRouteRef, tabbedCatalogRouteRef, tabbedDirectoryRouteRef) using the new API (no id param required) - Export plugin as default; keep SoCatalogIndexPageEntityList, SoTabbedCatalogIndexPage, SoTabbedDirectoryIndexPage as named exports - Add @backstage/frontend-plugin-api to dependencies; replace @backstage/dev-utils with @backstage/frontend-defaults in devDependencies; add react-dom to peerDependencies - Update dev/index.tsx to use createApp from @backstage/frontend-defaults - Add plugin to app features in App.tsx - Update plugin.test.ts to use test() per convention and validate default export

…default catalog page

…pha exports

It's not a page and we don't use this component elsewhere.

@copilot Please update the PR's initial comment based on the current state of the branch

I can’t edit the PR’s initial comment/description from this environment. Based on the current branch state, it should describe the package root exporting the new frontend plugin wiring, the app importing @internal/backstage-plugin-serverlessops-catalog from the root, the plugin dev app using @backstage/frontend-dev-utils, and the tabbed page blueprints being renamed and served under /serverlessops-catalog/* paths.

@copilot If you could edit the first commit based on the current state of the branch what would you write?

@copilot If you could edit the first commit based on the current state of the branch what would you write?

I’d rewrite it along these lines:

Migrate serverlessops-catalog to the frontend plugin entrypoint

move serverlessops-catalog to createFrontendPlugin / PageBlueprint wiring at the package root
export the frontend plugin plus the tabbed catalog and directory page blueprints from src/index.ts
update the app to consume @internal/backstage-plugin-serverlessops-catalog from the root entrypoint
switch the plugin dev app to @backstage/frontend-dev-utils
mount the tabbed catalog and directory pages under /serverlessops-catalog/catalog and /serverlessops-catalog/directory to avoid conflicts with the default catalog routes
align the package metadata and plugin export tests with the current frontend-plugin surface

a package change in this branch caused the latest `knex` to be pulled in which brought in the latest `tarn` which causes tsc to fail.
