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

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
realtime	Socket.IO realtime layer (ADR-016)
events	Cross-feature event bus + Payload jobs adapter (ADR-015)
trpc	tRPC server setup
ui	Design-system package
audit	DPA-compliant audit logging (ADR-018)

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:

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.
