creating-packages

A package is a concept. The lighter-weight alternative — extending the @kitz/effect namespaces in place — is the creating-modules skill. Use this skill when a concept warrants its own publishable @kitz/<name> package.

Scaffolding is a real Vite+ generator: a Bingo template at generators/package, registered in vite.config.mts under create.templates as package.

Steps

1. Generate (non-interactive; vp create auto-formats the output):

   pnpm exec vp create package -- --name <name> --directory ../packages/<name> --offline --skip-requests
   

   <name> is the unscoped name (color → @kitz/color); the library lands in packages/<name>. The ../packages/ prefix is required because vp create resolves --directory relative to the generator's own location (generators/), so escaping up keeps generated libraries in packages/, not generators/. Add --description "<one-liner>" to set the description. (Humans can also run vp create package interactively — it prompts for the directory; answer ../packages/<name>.)

2. Wire into the root solution — tsc project references are not globbed, so add the new package to both root solution configs:

   • tsconfig.development.json → references: { "path": "./packages/<name>/tsconfig.development.json" }
   • tsconfig.production.json → references: { "path": "./packages/<name>/tsconfig.production.json" }

3. Link: pnpm install.

4. Verify: pnpm exec vp run check (format + lint + types) and pnpm exec vp run build.

What the generator produces

packages/<name>/
├── package.json              # @kitz/<name>: live-types exports (src .ts dev /
│                             #   build .js publish), effect peer, prepack,
│                             #   files: [build, src]
├── README.md
├── tsconfig.json             # solution pointer → development + production
├── tsconfig.development.json # extends root stage.development template
├── tsconfig.production.json  # extends stage.production + topology.imported
└── src/
    ├── _.ts                  # namespace bundle: export * as <Name> from './__.js'
    └── __.ts                 # implementation barrel (starts empty)

The output matches @kitz/effect — read it as the canonical example. If the package shape changes, update the template at generators/package/src/template.ts (and validate by generating a throwaway package, then pnpm exec vp run check).

Notes

• @generator/package is private (not published); it exists only to drive vp create.
• To add a namespace to an existing package (including @kitz/effect), use creating-modules — that is an in-package edit, not a generator.
