It blows my mind when JS packages publish for every commit and end up with thousands of versions on npm. For example, Primer React publishes ~20 - 30 times a day via commit-based CI. Good dev pattern, or misuse of npm?

@dr_sensor JS module sources are on the roadmap, but not supported yet.

@dr_sensor Yes it supports source phase too when enabled, covered at the end of the post.

RT @guybedford: Announcing ES Module Shims 2.0. The latest version of what started out as an import maps polyfill now supports production p…

See the announcement post for an example of running a TypeScript Vue app with #nobuild. Other recent features including Wasm modules with source phase imports and multiple import maps are also explained in more detail.

As someone who's worked considerably on build tools, I never use one when authoring a web app personally. ESM is great actually.

RT @rough__sea: 5 years later, issue 2552 is closed!

Shopify's Hydrogen React adds a "./*" entry in its package.json "exports" field. Please never ever do this - it makes every module in the package public meaning you can't change a single interface without that being a semver major. Public interface matters!

My team at Fastly is hiring for an engineering role on our JS-on-Wasm runtime for Fastly’s edge compute platform.

@jankrems Don’t start with a dot is pretty much it I think. We could definitely add some restrictions further.

@NicoloRibaudo Easy mode. On W US timezone if waking up at 8am that is 5pm EU. So shift back sleep schedule 9 hours (or 12 hours for E US) to wake up 2am in EU for meeting. So stay up for overnight flight from US then get on this schedule. After that enjoy your new super early bird lifestyle.

@AndaristRake @bradleymeck Thanks for the ping, I’ll follow this up.

@bluwyoo @robpalmer2 @TC39 Having a standard enables compat across runtimes. Bundler-only patterns aren’t good to rely on for portability / libraries. Early on we did explore general assets (, but browser fetch model requires knowing the type ahead of time. Assets may happen too.
