Snowpack v3.0: Reimagining Web Development with ESM — You can now import any npm package on demand (with streaming imports), and there’s a new native JavaScript API. Oh, and it’s the one year anniversary of Snowpack’s 1.0 release! 🎉

Fred K. Schott

We asked Snowpack’s creator, Fred K Schott, for a few words on Snowpack 3.0:

“I couldn’t be more excited about this launch! Streaming imports are a game changer that simplify dependency management by fetching packages as soon as you need them: pre-built, pre-bundled and ready to run.

We also shipped a first-class integration with esbuild to bundle Snowpack builds 100x faster than Webpack, Rollup or Parcel (seriously, look at these benchmarks!). If you haven’t had a chance to check out Snowpack yet, v3.0 is a great chance to jump in.”
