Changes

  • Follow up from debugging with @melissamcewen
  • For react users, replacing your build with Babel is a huge ask just to enable Fast Refresh
  • Instead, we pull Babel into the fast-refresh plugin to run by default (option added for older behavior).
  • This dramatically simplifies the CSA apps (no longer need Babel for build pipeline, can rely on faster, internal esbuild engine)

Testing

  • Tested manually.

Docs

  • Readme docs updated.

somewhat related: tested with Melissa to confirm that this is no longer needed (included by default by Babel)

we now use esbuild instead of Babel in this app, which created the output changes here

Hi @FredKSchott, with this PR, TypeScript users can use react-refresh without babel totally. Please consider it

That PR does not apply to Snowpack. Fast Refresh in Snowpack supports both JS & TS (you can try out our latest React TS template to confirm)
