Backstage 1.46.0 Migration Recipe

Runs every @backstage/* v1.46.0 codemod from the registry in a single ordered run.

Codemods included

#	Package	Domain	Registry
1	`@backstage/add-jest-peer-dependency`	CLI / tooling	link
2	`@backstage/migrate-valkey-config`	Backend config	link

bash

These changes require manual attention and are not covered by the recipe:

TechDocsAddonTester.renderWithEffects() screen change — narrow scope, requires new npm dep (shadow-dom-testing-library)
Jest peer dep version choice — the codemod defaults to Jest 30 (recommended); use --param jestVersion=29 for Jest 29
Jest 30 test code migration — asymmetric matchers, JSDOM 27 changes; see Jest 30 migration guide
getBitbucketCloudRequestOptions now returns Promise — narrow internal API
CLI moduleResolution → bundler default — tsconfig defaults, not consumer code
Node.js 22/24 requirement — runtime environment
