Other changes to consider:
|
|
With RR v9, we now expect to work with React 18+, which always batches. So, we no longer even use |
|
@markerikson ahh I see, that's not a problem at all, maybe if we were to do a major (perhaps for React 19 though I highly doubt it'll be necessary), we can remove them then. Also not sure if you saw I did remove |
|
I honestly don't even remember why we had that there :) |

This one will be trickier to review than the other repos, so I'll come back to this when I have more time to look at it. |

- `env` is the same thing as `define` with `JSON.stringify`.
- Currently there is no difference between emitting type definitions with `cjs` or `esm` format, the only difference is the file extension. So we emit the type definitions with a `cjs` format to preserve the previous `.d.ts` extension as opposed to the new `.d.mts` extension.
- The conditional import of the `React` namespace seems to create a lot of side effects, so for now we'll de-duplicate the `React` namespace imports by funneling them through `src/utils/react.ts`.
- This was mainly done to stay consistent with other Redux repos.
- This was done to ensure that the remaining traces of dev mode checks will not be present in the `'production'` build.

Okay, dug through the code changes and the build output, and this seems reasonable. We'll go with it! |
