You can use esm.run links for quick demos or prototyping. In production (once this feature is out of beta), always use our main domain.
Global Multi-CDN powered by jsDelivr
esm.run is powered by jsDelivr and it's sponsors like Cloudflare, Fastly, Bunny, and GCore. This guarantees the best performance and uptime globally, including mainland China.
On-demand builds with permanent storage
Once built, files are stored in a permanent storage shared by all edge servers. That means future access will be always fast, even for files not yet cached at the CDN edge.
State-of-the-art delivery
HTTP/2, HTTP/3, code minification, brotli compression, fine-tuned HTTP caching, dependency preloading - we always use all available options for improving the overall performance.
