Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Unit Testing Expo Apps With Jest
To fix this, the simple way is to mock a redux store. I need to install redux-mock-store and its typing:
- what's your take on the tdd approach? how are tests tested ?

Redux Testing Lessons Learned: Give your Components Access to your Reducers
For a long time I relied on redux mock store to preload data into my components for rendering during tests. This approach makes it easy to take a snapshot of a component with arbitrary data and ensure that it renders correctly. Where it completely fails is testing interactions.

Redux Testing: Hard-Earned Lessons Learned
Redux Toolkit includes a configureStore method that allows you to preload it with state. The createStore method in redux includes this option as well. In the old days I would rely on tools like redux mock store to generate redux stores for testing, but you don't need it. You can generate a store for your tests that includes exactly the same reducers as your app, but also comes pre-loaded with whatever state you need for your tests.

Testing of redux-thunk action
The above example checks the actions executed by someThunkFunction. The mockStore function used in the example comes from the redux-mock-store library.

Redux Toolkit 2.0: new features, faster perf, smaller bundle sizes, and more
- Throws better errors in an RSC environment
- https://github.com/reduxjs/react-redux/releases/tag/v9.0.0
## Reselect 5.0:
- Switches to a new `weakMapMemoize` memoizer as default
- Renames `defaultMemoize` to `lruMemoize`
- Allows passing memoizer options direct to `createSelector`
- Many TS improvements
- https://github.com/reduxjs/reselect/releases/tag/v5.0.1
## Redux Thunk 3.0:
- Drops the default export and switches to named exports ( `{thunk, withExtraArgument}` )
- https://github.com/reduxjs/redux-thunk/releases/tag/v3.1.0
This has been a _huge_ year-long development effort!
We're thrilled to get these improvements out. The tooling and bundle improvements will help all users, and we think the features and TS changes will improve the Redux dev experience significantly.
Thank you SO MUCH to everyone who has contributed or helped test out the work!
Please file bug reports for the inevitable issues that pop up post-release!
but now I'm going off on a conf trip and going to take a very well-earned break from Redux work for December :)

Recap of the state management history in React
Since it was a relatively low level tool, just like React, that gave a lot of freedom to the user to find different ways to make it work for them. In particular when it came to async operations Redux itself gave no official solution. The most popular options are redux-thunk, redux-observable, and redux-saga. There were probably a dozen more options out there.
