Breaking Changes

  • File watching strategy switched to @parcel/watcher

    • Most setups should be fine, but if issues appear, like when using WSL with host, volumes, or remote setups—switch to polling.
    • Set METEOR_WATCH_FORCE_POLLING=true to enable polling.
    • Set METEOR_WATCH_POLLING_INTERVAL_MS=1000 to adjust the interval.

  • [email protected]

    • Independent from the core, only applies if upgraded manually.
    • useFind describes no deps by default PR#431

Internal API changes

  • [email protected] - Depends on Meteor’s webapp package.
    • Deprecates non-native promise usage #154
    • Use async/await or Promise.resolve when defining endpoints to avoid deprecation warnings.

Migration Steps

Please run the following command to update your project:

bash
meteor update --release 3.3

To apply react-meteor-data changes:

bash
meteor add [email protected]

Add this to your package.json to enable the new modern build stack:

json
"meteor": {
  "modern": true
}

These settings are on by default for new apps.

On activate modern your app will be updated to use SWC transpiler. It will automatically fallback to Babel if your code can't be transpiled wit SWC.

Check the docs for help with the SWC migration, especially if your project uses many Babel plugins.

Modern Transpiler: SWC docs
