Full Changelog: v0.79.0...v0.79.1

v0.79.0

• [Breaking]: Disable global package resolution (resolver.enableGlobalPackages) by default (0df1541 by @robhogan)
• [Feature]: Add option to configure Metro's support for global package resolution (aka "Haste packages") (8b80efb by @motiz88)

• [Feature] Add base URL string overload to InspectorProxy.createWebSocketListeners (8522db1 by @huntie)

Note

v0.78.1 will be the final release of metro-inspector-proxy, which is being relocated into the React Native repo. In Metro v0.78.0, we removed builtin Inspector Proxy creation as a breaking change.

• For React Native integrators: The @react-native/dev-middleware package will provide a batteries-included integration point replacing metro-inspector-proxy. We're working closely with Expo on the API for this which should be ready within the next two weeks — usage will be documented in the package README.
• Please reach out to @huntie (https://twitter.com/alxhnt) if you need support around this change.

v0.78.0

• [Breaking] Update default server port to 8081. (891fe96 by @huntie)
• [Breaking] Remove metro-react-native-babel-transformer and metro-react-native-babel-preset, which will be published as @react-native/metro-babel-transformer and @react-native/babel-preset going forward. (799aa0a by @dmytrorykun)
• [Breaking] Remove runInspectorProxy option from server. (2b0b15d by @huntie)
  • This is a significant breaking change — Metro will no longer start a built-in Inspector Proxy.
  • To migrate today, integrators should create an InspectorProxy instance externally, and provide the relevant handlers to Metro.runServer(). For reference:
    • inspectorProxy.processRequest to ServerOptions.unstable_extraMiddleware.
    • inspectorProxy.createWebSocketListeners to ServerOptions.websocketEndpoints.
  • Recommended: In the very near future, we will be encapsulating this functionality in the @react-native/dev-middleware package, which will provide a batteries-included integration point for the above.
  • Please reach out to @huntie if you need support with this feature.
