It works a lot like NPM but is specifically intended for use with front-end modules.
Features:
- uses System.js (a polyfill for the future ES6-module-loader spec
- supports CommonJS, AMD, and UMD formats
- has plugins for importing other types (ex css)
- support Typescript/Traceur/Babel out of the box
- uses a flat dependency structure (ie like NPM v3)
- can generate bundles and self-executing bundles (incl tree shaking and minify)
- tracks specific versions of dependencies
Unlike NPM, module installation doesn't depend on packages published to a central registry. It can install versioned modules directly from GitHub and NPM. The registry it uses is nothing but GitHub repo with module-to-repo mappings and compatibility shims.
Here's the link: http://jspm.io/
Lodash is already included in the registry: http://kasperlewau.github.io/registry/#/?q=lodash
npm install visionmedia/express
Or any git repo: npm install git+https://[email protected]/visionmedia/express.git
npm install git+ssh://[email protected]/visionmedia/express.gitThanks for the tip. I wish my comment wasn't locked in already so I could correct the misinformation.
It doesn't cover any of the functionality that JSPM provides and publishing modules as RPM only makes them available to (at most) 1%-2% of users.
JSPM is written in Node and available via NPM. So... it works on pretty much anything out of the box.
