JSPM is a package manager for browser-native ES modules built around import maps, comprising a CLI, the @jspm/generator library, and import map manipulation tools. It resolves npm packages against CDNs like jspm.io, jsDelivr, and UNPKG, and can inject import maps with preloading and integrity attributes into HTML files.
Use cases
- manage frontend dependencies with import maps instead of a bundler
- generate import maps for npm packages served from a CDN
- install and link packages to local node_modules for browser ES modules
- inject import maps with module preloading and integrity into HTML
- serve and build a no-build-step JavaScript project
- resolve conditional package versions per environment in the browser
When to choose
- you want browser-native ES module loading without a bundler or build step
- you want CDN-cached dependencies with immutable URLs for faster incremental updates
- you need standards-based import map generation and management in a CLI or programmatically
When to avoid
- you need a traditional bundler pipeline with code splitting and asset transforms
- your project targets older browsers without an import maps polyfill strategy
- you rely heavily on Node.js-specific tooling and CommonJS packages
