If you haven't had a chance to check out Snowpack yet, v3.0 is a great chance to jump in.” [Node Package Maintainers, Get Ready For ES Modules](https://blog.sindresorhus.com/get-ready-for-esm-aa53530b3f77) — ES modules are rapidly becoming a day to day reality for Node.js package maintainers, so spare a thought for Sindre who has about 20 million packages (_slight exaggeration_) to his name.
