海外TECH	DEV Community	Recoil is the Samurai Sword of React State Management	https://dev.to/codeofrelevancy/recoil-is-the-samurai-sword-of-react-state-management-1eg0	Recoil is the Samurai Sword of React State ManagementRecoil was created to provide an alternative to Redux which is another popular state management library for React In today s adventure we will see what Recoil is how it works why you might want to use it in your React apps and much more With a spirit of the samurai let s begin our adventure Installing RecoilYou can install Recoil using npm or yarn by running the following command in your terminal npm install recoilComponents that use recoil state need RecoilRoot to appear somewhere in the parent tree A good place to put this is in your root component import React from react import ReactDOM from react dom client import RecoilRoot from recoil import App from App ReactDOM createRoot document getElementById root as HTMLElement render lt React StrictMode gt lt RecoilRoot gt lt App gt lt RecoilRoot gt lt React StrictMode gt This ensures that the state is available to all child components that require it and avoids any potential issues with components not being able to access the state due to missing RecoilRoot components What is Recoil Recoil is a state management library for React that was released by Facebook in It provides a simple and intuitive way to manage the state of a React application Recoil is built on top of React s Context API which is used to pass data down the component tree Anyway Recoil provides a more powerful and flexible way to manage the state of an application than the Context API The core idea behind Recoil is that state should be defined as a collection of atoms An atom is a piece of state that can be read and updated by components Components can subscribe to atoms to be notified when their value changes Recoil also provides selectors which are functions that derive new state from atoms or other selectors Selectors can be used to compute derived data from the state of an application How does Recoil work Recoil works by defining a collection of atoms and selectors that represent the state of an application Atoms are defined using the atom function it takes an initial value as a parameter Selectors are defined using the selector function which takes a function that computes the derived state as a parameter Create an atomIn the way of Recoil an atom is a unit of state that can be read and written to by different parts of your app To create an atom you can use the atom function from the Recoil library To show you what I mean import atom from recoil export const weaponState atom key weaponState default name Katana damage Use the atom in a componentComponents can subscribe to atoms and selectors To use the weaponState atom in a component you can use the useRecoilState hook from the Recoil library To show you what I mean import React from react import useRecoilState from recoil import weaponState from atoms function WeaponDisplay const weapon setWeapon useRecoilState weaponState return lt div gt lt h gt weapon name lt h gt lt p gt Damage weapon damage lt p gt lt button onClick gt setWeapon name Nodachi damage gt Upgrade Weapon lt button gt lt div gt As per above instance we re using the useRecoilState hook to access the weaponState atom and its current value We re also providing a button that allows the user to upgrade their weapon by setting the atom to a new value Create a selectorSelectors are functions that allow you to derive state from your Recoil atoms They can be useful for computing complex values or aggregating data from multiple atoms To show you what I mean import selector from recoil import weaponState from atoms export const weaponDamageSelector selector key weaponDamageSelector get get gt const weapon get weaponState return weapon damage Use selector in a componentWe can then use selector in our components using the useRecoilValue hook same as atoms To show you what I mean import React from react import useRecoilState from recoil import weaponDamageSelector from selectors function WeaponDisplay const weaponDamage useRecoilState weaponDamageSelector return lt div gt lt p gt Weapon damage weaponDamage lt p gt lt div gt Create an atomFamilyIn the samurai world a clan may have multiple samurais and each with their own unique characteristics and abilities Similarly in a React application you may have multiple components that need to share state but with different identifiers or keys This is where atomFamily comes in handy It allows you to create a family of atoms that share the same structure but with different keys or identifiers As an instance let s say we want to create a family of atoms that represent the weapons of different samurais in a clan import atomFamily from recoil export const weaponAtomFamily atomFamily key weaponAtomFamily default id gt name Weapon id damage In above instance id argument in the default function is the unique identifier for each atom in the family So when we call weaponAtomFamily Wakizashiv the default function will be called with Wakizashiv as the id argument and will return an object representing the default weapon for that samurai Use atomFamily in a componentAn atomFamily takes almost the same options as a simple atom But the default value can also be parameterized That means you could provide a function which takes the parameter value and returns the actual default value import React from react import useRecoilState from recoil import weaponAtomFamily from atoms function WeaponDisplay const weapon setWeapon useRecoilState weaponAtomFamily Wakizashiv return lt div gt lt h gt weapon name lt h gt lt p gt Damage weapon damage lt p gt lt button onClick gt setWeapon name Weapon Nodachi damage gt Upgrade Weapon lt button gt lt div gt Why use Recoil Recoil provides several benefits over other state management libraries for React such as Redux Let s see some reasons why you might want to use Recoil in your React projects Simplified state managementRecoil provides a simpler and more intuitive way to manage the state of a React app With Recoil you can define atoms and selectors that represent the state of your app Components can subscribe to these atoms and selectors to be notified when their value changes No boilerplateRecoil also reduces the amount of boilerplate code that is required to manage the state of a React app It allows you to define atoms and selectors with minimal boilerplate code On otherside in Redux you need to define actions action creators reducers and store objects to manage the state of your app Better performanceRecoil provides better performance than other state management libraries for React This is because Recoil uses a new algorithm called the Dependency Graph which allows it to track the dependencies between atoms and selectors more efficiently The Dependency Graph ensures that only the components that need to be re rendered are re rendered when the state of an atom or selector changes which improves the performance of your app Familiar syntaxRecoil uses a syntax that is similar to React s built in hooks such as useState and useEffect This makes Recoil easy to learn and use for developers who are already familiar with React Flexible and scalableRecoil is designed to be flexible and scalable It can be used to manage the state of small or large apps with complex state requirements It allows you to define atoms and selectors that represent different parts of your app s state and it provides tools for managing the dependencies between these atoms and selectors Battle of Recoil and ReduxLet s unfold the final chapter of our adventure together as fearless samurai warriors What is Atom Effects Atom Effects is a feature in Recoil that allows you to execute side effects when an atom s value changes Side effects are any operations that have an impact outside of the atom s state Such as network requests local storage or logging Atom effects are attached to atoms via the effects option Each atom can reference an array of these atom effect functions which are called in priority order when the atom is initialized With the help of Atom Effects you can add subscriptions to an atom that will be triggered whenever the atom s value changes The subscriptions can execute any side effects that are necessary for your app The side effects can be synchronous or asynchronous Atom Effects can be useful in situations where you need to execute side effects based on the current state of your app As instance you may want to save the user s preferences to local storage whenever they make a change to a settings page Atom Effects are the hidden forces that shape the world around us just as a samurai s sword is shaped by the unseen interactions of its atoms To show you what I mean import atom useRecoilState from recoil export const weaponState atom key weaponState default name Katana damage Atom Effects effects onSet gt onSet weapon gt console log The weapon has upgrade to weapon name function WeaponDisplay const weapon setWeapon useRecoilState weaponState return lt div gt lt h gt weapon name lt h gt lt button onClick gt setWeapon name Nodachi gt Upgrade Weapon lt button gt lt div gt The onSet callback is called whenever the value of the weaponState atom changes In above instance we re simply logging the new weapon of the atom to the console but we could just as easily execute a more complex side effect End of adventureRecoil is built on top of React s Context API and provides a more powerful and flexible way to manage the state of an application than the Context API It allows you to define atoms and selectors that represent the state of your app Components can subscribe to these atoms and selectors to be notified when their value changes Recoil provides several benefits over other state management libraries for React such as simplified state management no boilerplate better performance familiar syntax and flexibility and scalability If you re looking for a state management library for your React projects Recoil is definitely worth considering Motivation
