This is a repository to reproduce an error related to types of react-redux.
In the application, we have two components, Counter1
and Counter2
. They are fully identical
in function and also in code except for the first one having mapDispathToProps
as an object shorthand and the second one having it as a function. The mapDispathToProps
binds a thunk
action for the use of the counters. The second one works as expected, but in the first one, when using connect
to the component, we get a typescript compiler error:
Argument of type '(props: Props) => Element' is not assignable to parameter of type 'ComponentType<Matching<{ sum: number; clickCount: number; } & { count: (amount: number) => Promise<void>; }, Props>>'.
Type '(props: Props) => Element' is not assignable to type 'FunctionComponent<Matching<{ sum: number; clickCount: number; } & { count: (amount: number) => Promise<void>; }, Props>>'.
Types of parameters 'props' and 'props' are incompatible.
Type 'PropsWithChildren<Matching<{ sum: number; clickCount: number; } & { count: (amount: number) => Promise<void>; }, Props>>' is not assignable to type 'Props'.
Types of property 'count' are incompatible.
Type '(amount: number) => Promise<void>' is not assignable to type 'CountThunk'.
Type 'Promise<void>' is not assignable to type 'ThunkAction<Promise<void>, {}, {}, IncreaseSumAction | IncreaseCountAction>'.
Type 'Promise<void>' provides no match for the signature '(dispatch: ThunkDispatch<{}, {}, IncreaseSumAction | IncreaseCountAction>, getState: () => {}, extraArgument: {}): Promise<void>'.
This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build
folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject
, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject
at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject
will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject
. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
You can learn more in the Create React App documentation.
