Episode notes
ESM Only
- JSR is ESM-only to facilitate better static analysis and simplify package creation.
- ESM's statically analyzable nature enables features like documentation generation and linting.
JSR and NPM Compatibility
- JSR acts as a proxy, fetching packages from its registry if available, otherwise falling back to NPM.
- This ensures compatibility with existing NPM packages while promoting JSR adoption.
JSR's Open-Source Nature
- JSR is open-source and community-driven, unlike NPM's closed-source, for-profit model.
- This fosters transparency, collaboration, and avoids potential conflicts of interest.
