CDN & downloads

Pinned, immutable URLs with integrity hashes. Served with CORS and long-lived caching, so any site can use them safely.

Production (minified) — recommended

All URLs

URL	Caching	Use for
`/cdn/1.0.0/jskjs.min.js`	1 year, immutable	Production (with SRI)
`/cdn/1.0.0/jskjs.js`	1 year, immutable	Debugging (with SRI)
`/cdn/jskjs.min.js`	1 hour	Always-latest experiments — no SRI, may change
`/cdn/jskjs.js`	1 hour	Always-latest source

Why pin?An integrity hash only matches one exact file. The versioned URLs never change, so the hash stays valid and browsers can cache them for a year. The “latest” URLs will change with each release — never combine them with integrity.

Self-hosting

Copy jskjs.min.js next to your pages and reference it with a relative path. It has no dependencies and needs no build step. If you serve it cross-origin with SRI, send Access-Control-Allow-Origin: *. The source is also on GitHub.
