海外TECH	DEV Community	Conditional rendering in React made easier and reusable "no library"	https://dev.to/bazenteklehaymanot/conditional-rendering-in-react-made-easier-and-reusable-no-library-4848	Conditional rendering in React made easier and reusable quot no library quot If you ever worked with react it is likely that at some point you implemented some conditional rendering such as the followingexport const Component FC gt const isLoading setIsLoading useState lt boolean gt Some logic return lt Fragment gt isLoading lt LoadingComponent gt lt Content gt lt Fragment gt While this is fine it is limited to two values true amp false which is not always the case moreover it complicates the component code as our component grows lets see at other way of implementing this interface ConditionalRendererProps activeState string mapping key string React ReactNode export const ConditionalRenderer FC lt ConditionalRendererProps gt props gt return lt Fragment gt props mapping props activeState lt Fragment gt The idea behind this implementation is to use ConditionalRenderer as a wrapper component and pass a mapping and activeState as a props mapping as its name indicates it contains state to component mapping meaning what component corresponds to a given state activeState is selected state from the mapping propsWhile this could seem over complicating the implementation it is actually more flexible that the first implementation and makes our code more cleaner well how okay to answer that lets take a look at another more common scenario where we need conditional rendering when we have task that needs sometime to complete e g when making API request in this scenario there is more than two states for now to keep things simple lets agree we have four states namely initial processing complete amp error amp we want to render different components depending on the active stateexport enum StateTypes Init INIT Error ERROR Success SUCCESS Processing PROCESSING The StateTypes enum defines all possible states next lets define generic wrapper component for components containing asynchronous actionsinterface StateMachineWrapperProps asyncTask Function component React ComponentType lt any gt export const StateMachineWrapper FC lt StateMachineWrapperProps gt props gt const machine useAsync lt string gt props asyncTask return lt ConditionalRenderer activeState machine currentState mapping StateTypes Init lt Fragment gt StateTypes Processing lt p gt machine message lt p gt StateTypes Error lt p gt machine message lt p gt StateTypes Success lt props component machine payload gt gt StateMachineWrapper renders components that comprises async actions It is highly likely that we have multiple components that communicate to an external API or perform some other async task and for every component we can use the StateMachineWrapper component and separate the side effect from our core component lets see the usage function longRunningTask return new Promise resolve reject gt setTimeout gt resolve data Async task completed To keep things simple the long running task does nothing practical but it is easy to modify the implementation according to your use case finally lets take a look at the core component interface ContentProps data string export const Content FC lt ContentProps gt props gt return lt div gt lt h gt Content lt h gt lt p gt props data lt p gt lt div gt export const ContentWrapper FC gt return lt StateMachineWrapper asyncTask longRunningTask component Content gt the Content component is pure component and is decoupled with the side effect or longRunningTask as you can see the initial effort pays off finally because the components that mimic the StateMachineWrapper are pure components and the concerns are separated this is one use case to demonstrate the ease of implementing conditional rendering in such a way Github gist can be found hereThank you for reading cheers	2021-04-29 18:27:13
