@backstage/create-app
patch

Migrated the app template use the new @backstage/app-defaults for the createApp import, since the createApp exported by @backstage/app-core-api will be removed in the future.

To migrate an existing application, add the latest version of @backstage/app-defaults as a dependency in packages/app/package.json, and make the following change to packages/app/src/App.tsx:

-import { createApp, FlatRoutes } from '@backstage/core-app-api';
+import { createApp } from '@backstage/app-defaults';
+import { FlatRoutes } from '@backstage/core-app-api';
