* fix config * export types * use export from, reorganize * fix stupid eslint rule breakage

* add overloads to compose.ts * add applyMiddleware overload fixes
* fix replaceReducer with a store enhancer * remove erroneous restriction on StateExt * remove the other extension - our store enhancer might add array functionality, for instance * add reasonable defaults for Ext and StateExt * fix state, add a test for non-object-based state * add verification that store extension is also passed to replaceReducer * better fix: set state default based on what base type it is * fix array test * fix typing of StateExt * add mhelmerson example * fix replaceReducer, so that it infers types, fix example test * fix the weird type hacks in the test * add final working example * update based on PR type changes * fix type * update tests to reflect complete examples * merge the changes from index.d.ts into types/store.ts * extend store type * much better approach: only extend the state when we have an extension * fix typing issues not caught before * add link to the place I learned about this
* fully move away from index.d.ts * build types into the types/ directory * remove autogenerated types dir * ignore auto-generated types * better type building, also clean old definitions * use types instead of typings Co-Authored-By: Jed Mao <jedmao@users.noreply.github.com> * Don't build declaration maps

I'm going to hold off #3563 until after this, since it's an enhancement to the types. I think we have everything in place now. Let's see what the CI says... |
|
CI is happy, but there's still an issue with type duplication and resolution that I fixed in #3564 |
* Defer to rollup TS plugin to build types * index.ts -> redux.js, redux.d.ts * Only output one copy of the types. This also puts them back into the types path. However, I don't know how to have them output as a single file bundle to match our other outputs. * Remove the move Co-authored-by: Tim Dorr <git@timdorr.com>

OK, one last thing I'd like to do is flatten the types to a single bundle. But I don't think that's critical to move on to the next stage: enhancement! Thanks to everyone for your help thus far! |
Very cool. 🎆 One thing though: While I see you are already aware of the "single bundle", I just wanted to chime in on how important that can be - please don't do a release before having the single type bundle: @babel/preset-typescript has severe problems with type re-exports ( babel/babel#8361 or babel/babel-loader#603 among dozens of others) that sometimes make libraries with multiple typings files & re-exports almost impossible to use with a webpack+babel-typescript setup. |

This is just a PR tracking our ts-conversion branch so we can have a quick overview of the status of things, commentable code, and a big green merge button to finish things up.
Closes #3500
