From 709d0d46b2b25a4a36367749b0e9a0aa88856efa Mon Sep 17 00:00:00 2001 From: Alex Hunt Date: Fri, 18 Aug 2023 02:10:03 -0700 Subject: [PATCH] Integrate dev-middleware into start command (#39059) Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/39059 ## Context RFC: Decoupling Flipper from React Native core: https://github.com/react-native-community/discussions-and-proposals/pull/641 ## Changes This change: - Links the new `react-native/dev-middleware` endpoints into the recently migrated `react-native start` command. - Adds `react-native/community-cli-plugin` (the migrated [`cli-plugin-metro`](https://github.com/react-native-community/cli/tree/main/packages/cli-plugin-metro)) as a dependency of `react-native`, and hooks in these versions of the `start`, `bundle`, and `ram-bundle` commands via `react-native.config.js`. Functionally, this means that the new `/open-debugger` endpoint is available on the dev server started by `react-native start` (not yet linked into any UI). After this PR is merged, the new `community-cli-plugin` package is "linked" and we can remove `cli-plugin-metro` from `react-native-community/cli`: https://github.com/react-native-community/cli/pull/2055.
