What and why

Closes #769.

Adding a block used to require editing several files by hand. This reduces it to a minimal, obvious task, which matters most for a downstream project adopting a published block package.

Changes

1. The generator registers a block in both apps automatically. The block generator already injected the registration markers; it now also adds @o2s/blocks.<name> to the dependencies of apps/api-harmonization and apps/frontend (inserted alphabetically, in place). So npm run generate scaffolds and fully wires a block with zero manual file edits, and the only follow-up is npm install.

2. Backend registration is centralized in one file. A new apps/api-harmonization/src/blocks.config.ts holds the block module array and the Blocks union. app.module.ts registers every block via ...blocks.map((block) => block.Module.register(AppConfig)), and page.model.ts re-exports Blocks. Previously this was split across app.module.ts and page.model.ts; now it is a single source of truth.

The frontend already had one registration point (renderBlocks.tsx), so it is unchanged. Its satisfies Record<Blocks, BlockRenderer> check still enforces backend/frontend parity at compile time.

Adding a block in a downstream project

A project based on this repo can adopt a published block with:

  1. npm install <block-package> (npm adds the dependency),
  2. add it to apps/api-harmonization/src/blocks.config.ts (one entry in the blocks array and one member in the Blocks union),
  3. add its renderer to apps/frontend/src/blocks/renderBlocks.tsx.

Two config files, and no edits to app.module.ts or page.model.ts.

Testing

  • npm run build, npm run lint, npm run test all pass across the monorepo.
  • Ran the block generator end to end: it scaffolds the block and injects into blocks.config.ts, renderBlocks.tsx, the CMS block model, and both app package.json files.
  • Ran both apps and verified in the browser that dashboard, invoices, notifications, services, orders, and cases render their blocks (payments summary/history, invoice list, notifications, services, orders summary/list, ticket summary/list, quick links), with no unknown-block warnings and no console errors.

Summary by CodeRabbit

  • New Features
    • Added centralized page-block registration for API Harmonization.
    • Block generation now automatically registers new blocks and adds required application packages.
    • Added compile-time validation for supported page block types.
  • Documentation
    • Updated generator guidance to reflect automatic registration and the remaining installation step.
  • Improvements
    • Improved dependency handling to preserve consistent package formatting during block generation.

The block generator already injected all registration markers (app.module,
page.model union, renderBlocks, framework cms.model). It now also adds
`@o2s/blocks.<name>` to the dependencies of apps/api-harmonization and
apps/frontend (inserted alphabetically, in place), so creating a block needs
zero manual file edits — the only follow-up is `npm install`.

The dependency insertion is a small pure, idempotent helper. The generator's
final message drops the two manual package.json steps accordingly, and the
"Using generators" guide is updated to reflect the automatic registration.

Closes #769
…ig.ts

Consolidate the backend block wiring into a single source of truth,
`apps/api-harmonization/src/blocks.config.ts`, which holds the module array
and the `Blocks` union. `app.module.ts` now registers every block via
`...blocks.map((b) => b.Module.register(AppConfig))`, and `page.model.ts`
re-exports `Blocks`. Adding a block is two edits in one file (an array entry
and a union member) instead of edits spread across app.module.ts and
page.model.ts.

This makes it easy to adopt a published block package in a downstream project:
`npm install` it, then add it in blocks.config.ts (backend) and renderBlocks.tsx
(frontend). The frontend `satisfies Record<Blocks, BlockRenderer>` check still
enforces backend/frontend parity at compile time.

The block generator now injects into blocks.config.ts (import, array entry,
union member) instead of app.module.ts/page.model.ts; the frontend registry,
CMS model, and package.json injections are unchanged. Docs updated.

Walkthrough

The change centralizes API Harmonization block registration and block type generation in blocks.config.ts. The block generator updates this registry and both application manifests automatically. The generator documentation now describes the reduced setup steps.

Changes

Block registration and generator automation

Layer / File(s) Summary
Central block registry and consumers
apps/api-harmonization/src/blocks.config.ts, apps/api-harmonization/src/app.module.ts, apps/api-harmonization/src/modules/page/page.model.ts
The app imports all blocks through blocks.config.ts. NestJS modules register from the shared array. The page model re-exports the shared Blocks union.
Generator configuration and dependency updates
turbo/generators/config.ts, apps/docs/docs/guides/using-generators.md
The generator updates block imports, registrations, type entries, and both application dependencies. The documentation updates valid block domains and describes the automated steps and the remaining npm install command.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 69a83

The PR centralizes block registration and updates generator-managed dependencies without introducing a concrete merge-blocking risk; it is merge-ready after normal checks and review.

Poem

A rabbit finds the blocks in line
The registry keeps their names in sign
Modules hop through one array
Dependencies join without delay
“Run npm install,” the rabbit says
Then bounds through tidy generator paths
