Patterns for authoring high-quality TypeScript libraries, extracted from studying unocss, shiki, unplugin, vite, vitest, vueuse, zod, trpc, drizzle-orm, and more. For Nuxt module development: use nuxt-modules skill Consider loading these reference files based on your task: DO NOT load all files at once. Load only what's relevant to your current task. Token efficiency: Main skill ~300 tokens, each reference ~800-1200 tokens - Starting a new TypeScript library (single or monorepo) - Setting up package.json exports for dual CJS/ESM - Configuring tsconfig for library development - Choosing build tools (tsdown, unbuild) - Designing type-safe APIs (builder, factory, plugin patterns) - Writing advanced TypeScript types - Setting up vitest for library testing - Configuring release workflow and CI - Create project structure → load references/project-setup.md - Configure package.json exports → load references/package-exports.md - Set up build with tsdown → load references/build-tooling.md - Verify build: pnpm build && pnpm pack --dry-run — check output includes .mjs , .cjs , .d.ts - Add tests → load references/testing.md - Configure release → load references/release.md - ESM-first: "type": "module" with .mjs outputs - Dual format: always support both CJS and ESM consumers - moduleResolution: "Bundler" for modern TypeScript - tsdown for most builds, unbuild for complex cases - Smart...
