海外TECH	DEV Community	Safe component state with useReducer and TypeScript	https://dev.to/czystyl/safe-component-state-with-usereducer-and-typescript-2m2f	Safe component state with useReducer and TypeScriptPhoto by Nelly Antoniadou on UnsplashUsing multiple useState s to control component state is a common practice in React codebases but it can result in unexpected behavior such as a forever loading component or a disabled submit button Let s see what such components usually look like const email setEmail useState const loading setLoading useState false const error setError useState lt string null gt null const success setSuccess useState lt string null gt null async function handleEmailSend setLoading true setSuccess null setErrorMessage null if isEmailValid email setLoading false return setErrorMessage Invalid email try const response await sendToAPI setLoading false setSuccess response setEmail catch error if error instanceof Error setErrorMessage error message setLoading false You can imagine that one missing setState can make an invalid UI state that we do not want We can use useReducer to make the code much cleaner and less error prone Let s start by defining all the different possible component states we want to handle type Typing type typing email string type Fetching type fetching type FetchSuccess type success message string type FetchFailed type failed error string We used type intersection to distinguish the correct type based on the type property Our reducer state will be a union of all defined above types plus email filed type ResponseState Typing Fetching FetchSuccess FetchFailed type BaseState email string type State BaseState amp ResponseState The reducer requires action types which typically include a type property We can utilize the valid UI states that we ve already defined eliminating the need for duplicating code when defining our actions type Action Fetching Typing FetchSuccess FetchFailed function reducer state State action Action State switch action type case typing case fetching case failed return state action case success return action email The reducer is straightforward thanks to the reuse of types from the reducer state for the actions and the fact that their shape aligns with the reducer action pattern The only exception is the success action where we also clear the email input value By connecting the reducer actions and state in this manner unexpected states should no longer be an issue Let s see how we can simplify our handlers async function handleEmailSend if isValidElement state email return dispatch type failed error Invalid email try dispatch type fetching const response await sendToAPI dispatch type success message response catch error if error instanceof Error dispatch type failed error error message The component render is also pretty clear and easy to understand lt div gt state type failed amp amp lt ErrorMessage error state error gt state type success amp amp lt Success message state message gt lt div gt The above example dismissed the invalid states and made our component safe so we can assume that we archive the goal Please let me know in the comments what you think about that kind of reducer typing and if you have used it before If you want to explore the full example here is the live example	2023-01-12 19:31:09
