With roughly two million downloads per months, there must be a lot of big and small companies using this package. Please share your success stories!

1. Which company?
2. Logo would be cool! (it implies that it is o.k. to publicly share that your company is using this project, otherwise leave it out)
3. What kind of project? How large? (code base size or team size)
4. If your project is open source or public, please share a link!

If you would consider providing long term support through donations that would be great! Open collective or Paypal (please mention immer in the comments both cases)

@mweststrate Firstly I want to say huge thanks for your library. The writing of redux reducers is much easier and faster with immer 🤤

A little bit about us:

There's a few projects at Google using immer in Angular + ngrx apps (I'm working on one of them). I can't remember which ones are publicly launched, but if you're curious I can look into it some more.

Our product is in development and when we release it then I will send details. By the way I like it.

At Quizlet we've adopted Immer as a replacement for ImmutableJS. Main reasons were that we kept running up against static typing problems and that it seems to be unmaintained.

At Staffmatch we’re working on a new redesigned app where immerjs is heavily used both for redux and useState. I have no words to express how awesome it is, how it eases working with any state and optimizations. Complex table - easy; dropdown, date picker to work smoothly in IE11 - not a problem. So thank you a lot for making such a beauty!

1. Staffmatch

3. Temporary work service; about 10 devs, 3 front.
4. New app isn't released yet.

At MESHLE we are using immer for the latest version of our app which was completely rewritten in typescript. We had to ditch immutablejs for immer considering how difficult it is to use immutablejs with static types. Thanks alot for the lib :clap:

At Course Hero we have started to use Immer on new React apps, where it is helping us simplify updates to complex state objects and increase the maintainability of the codebase.

Hello! Thanks for the awesome library!

1. ImaWakatta - learn Japanese the fun and interactive way

2. 

3. Small team (Myself as the dev and a few content authors). Code wise I would say medium? We moved from Redux to Immer + hooks, which greatly simplified everything.

4. https://imawakatta.com/ (soft launched, still working out some kinks)

Immer is awesome! Used it to implement an undo system in my small puzzle game (made as a hobby). Link to game: https://spyr.itch.io/riko

We use it all the time! I love immer. We build software for giant enterprise companies like ADP, paychex, HP, and more. Never have had an issue with immer.

I use it whenever I use React. I always prefer seeing state changes using this great tool instead of the ugly spread objects... ;) Thanks again for the amazing work!
