海外TECH	DEV Community	React state with a fragmented store	https://dev.to/aralroca/react-state-with-a-fragmented-store-18ff	React state with a fragmented storeThere are many ways to manage the React state between many components using libraries like Redux MobX Immer Recoil etc or using a React Context After using several of them I personally choose React Context because of its simplicity To use a React Context to manage the state you have to put the state in the Provider along with the method to update it Then you can consume it from the Consumer However the problem with React Context is that if you change the value of a single field of the state instead of updating the components that use only this field all components that use any field from the state will be re rendered Unfragmented state in React Context In this article I m going to explain the concept of fragmented store to solve this and how to use it in a simple and easy way What is a fragmented storeThe fragmented store makes it possible to consume each field of the store separately Since most of the components will consume few fields of the whole store it s not interesting that they are re rendered when other fields are updated Fragmented store in React Context To solve this with React Context you have to create a context for each field of the store which is not very feasible due to its difficulty Not recommended lt UsernameProvider gt lt AgeProvider gt children lt AgeProvider gt lt UsernameProvider gt Naturally if we have very few properties in the store it could work But when we start to have too many there will be too much logic implemented to solve the problem of re rendering since it would be necessary to implement each context for each property However I have good news it can be automatically created How to use a fragmented storeI created a tiny library b called fragmented store to make it super simple and easy to use It uses React Context underneath I ll explain later what it does exactly Fragmented store logo Create context add the ProviderJust as we would go with the React Context we need to create the context and add the provider to the application We ll take this opportunity to initialize the store to the data we want at the beginning import createStore from fragmented store It is advisable to set all the fields If you don t know the initial value you can set it to undefined or null to be able to consume the values in the same wayconst Provider createStore username Aral age function App return lt Provider gt rest lt Provider gt Consume one fieldFor the example we will make components that consume a field of the store As you ll see it s similar to having a useState in each component with the property that you want with the difference that several components can share the same property with the same value import createStore from fragmented store We can import hooks with the property name in camelCase username gt useUsername age gt useAgeconst Provider useUsername useAge createStore username Aral age function App return lt Provider gt lt UsernameComponent gt lt AgeComponent gt lt Provider gt Consume the username fieldfunction UsernameComponent const username setUsername useUsername return lt button onClick gt setUsername AnotherUserName gt Update username lt button gt Consume the age fieldfunction AgeComponent const age setAge useAge return lt div gt lt div gt age lt div gt lt button onClick gt setAge s gt s gt Inc age lt button gt lt div gt When the AgeComponent updates the age field only the AgeComponent is re rendered The UsernameComponent is not re rendered since it does not use the same fragmented part of the store Consume all the storeIn case you want to update several fields of the store you can consume the whole store directly The component that consumes all the store will be re render for any updated field import createStore from fragmented store Special hook useUnfragmentedStoreconst Provider useUnfragmentedStore createStore username Aral age function App return lt Provider gt lt AllStoreComponent gt lt Provider gt Consume all fields of the storefunction AllStoreComponent const store update useUnfragmentedStore console log store all store function onClick update age username Aral Roca return lt button onClick onClick gt Modify store lt button gt And again if we only update some fields the components that consume these fields will be re rendered while other components that consume other fields won t It only updates the username field other fields won t be updated The UsernameComponent is going to be re rendered while AgeComponent won t update username Aral Roca You don t need to do this even if it s supported update s gt s username Aral With this only the components that consume the username field with the useUsername hook would be re rendered How is implemented underneathThe fragmented store library is a single very short file It s similar of what we d manually do to create several React Contexts for each property It automatically creates everything you need to consume and update them hooks import React useState useContext createContext from react export default function createStore store const keys Object keys store const capitalize k gt k toUpperCase k slice k length storeUtils is the object we ll return with everything Provider hooks We initialize it by creating a context for each property and returning a hook to consume the context of each property const storeUtils keys reduce o key gt const context createContext store key Property context return o All contexts contexts o contexts context key Hook to consume the property context use capitalize key gt useContext context We create the main provider by wrapping all the providers storeUtils Provider children gt const Empty children gt children const Component storeUtils contexts map context key gt children gt const ctx useState store key return lt context Provider value ctx gt children lt context Provider gt reduce RestProviders Provider gt children gt lt Provider gt lt RestProviders gt children lt RestProviders gt lt Provider gt Empty return lt Component gt children lt Component gt As a bonus we create the useUnfragmentedStore hook to return all the state Also to return an updater that uses all the created hooks at the same time storeUtils useUnfragmentedStore gt const state const updates keys forEach k gt const s u storeUtils use capitalize k state k s updates k u function updater newState const s typeof newState function newState state newState Object keys s forEach k gt updates k amp amp updates k s k return state updater Return everything we ve generated return storeUtils DemoI created a Codesandbox in case you want to try how it works I added a console log in each component so you can check when each one is re rendered The example is super simple but you can try creating your own components and your state ConclusionsIn this article I ve explained the benefits of the fragmented store concept and how to apply it with React Context without the need to manually create many contexts In the example of the article and the fragmented store library the fragmentation level is only at the first level for now The library I ve implemented is in a very early stage and there are certainly a number of improvements that could be made Any proposal for changes can be made on GitHub as the project is open source and will be very well received	2021-09-24 16:14:44
