v 8.4.1 Typing Issues

[pmkroeker]

I just updated preact to the latest version and I got a new slew of typescript problems (typings were updated so I figured I would get a few). But the curious thing I encountered was that some of the errors were being generated by the preact.d.ts file itself. It works fine when I build without preact-redux, but it throws the below errors when I do.

ERROR in [at-loader] ./node_modules/preact/dist/preact.d.ts:1:1

Might these errors get thrown from within other parts of my code? Going to work through some of the other problems right now, so I might fix them during the process. Will report back if I manage to solve the issue.

It seems that the issue is with the typings in preact-redux. Currently preact-redux and preact v8.3.1 are compatible, but upgrading to preact v8.4.1 causes some errors to pop up.

Closing as I did some file cleanup and forgot to update preact in a parent environment.
