# Core-package generator

`pnpm turbo gen core-package` scaffolds an optional core package back into a slimmed template. Each name maps to a verbatim copy of the package as it shipped at the time the generator was added.

## Usage

```bash
pnpm turbo gen core-package
# → Which optional core package? (use arrow keys)
#   ❯ realtime
#     events
#     trpc
#     ui
```

The generator emits the package files, updates consuming-app config (e.g. `apps/web-next/next.config.mjs` `transpilePackages`), patches `packages/core-eslint/base.js` to re-add any package-specific lint rules, then prints the manual app/server wiring needed to bring the package fully online.

## Available templates

| Name | Description | Phase added |
|---|---|---|
| `realtime` | Socket.IO realtime layer (ADR-016) | Phase 3 |
| `events` | Cross-feature event bus + Payload jobs adapter (ADR-015) | Phase 4 |
| `trpc` | tRPC server setup | Phase 5 |
| `ui` | Design-system package | Phase 6 |

(Until Phases 3-6 land, the generator will list an empty choices array and reject any selection.)

## Verifying an existing project

If your project already has a core-* package and you want to verify the generator's template hasn't drifted from the shipped source, use the byte-identical reconstruction snapshot:

```bash
git stash -u
pnpm turbo gen core-package <name>
git diff packages/core-<name>/
# Expect: zero diff (modulo .hbs strip + trailing-newline normalization)
```

Snapshots live at `turbo/generators/__snapshots__/core-package/<name>.snapshot.json` (added in Phases 3-6).
