Package Publishing

Overview

Covers modern npm package authoring: package.json configuration with the exports field, dual ESM/CJS builds, TypeScript type declarations, and secure publishing workflows with provenance.

When to use: Configuring package entry points, setting up conditional exports, building dual-format packages, publishing scoped packages, or troubleshooting module resolution.

When NOT to use: Application-level bundling (Vite/webpack app configs), monorepo workspace orchestration (Turborepo/Nx), private registry setup (Verdaccio/Artifactory).
