Configure recoil.js to your React project

Configuring Recoil.js in your React project involves setting up the state management library Recoil to manage the state of your application. Recoil offers a flexible and efficient way to manage the global state and makes it easy to share and update data across components. Here's a step-by-step summary of how to configure Recoil.js in your React project:

What is recoil.js to React?

recoil.js is the state management library for React. Hence it can be used instead of usestate in your React Project.

How are they different from each other?

It seems like React ( global version of useState)

You can manage your state very easily.

It has very simple concepts like atom and selector.

Very clean and simple working model.

Installation:

for npm package: npm install recoil

for yarn package: yarn add recoil

Implementing State

Atom

An atom represents a piece of state. Atoms can be understood as something that can be read from and written to from any component. Components that are associated with this atom will automatically be re-rendered once the atom is updated.

Selectors

A selector represents a piece of derived state. You can think of this as the output of passing state to a function that modifies the given state in some way.

Using State:

There are two ways to get the declared state into our components. i.e. by useRecoilState or useSetRecoilState, useRecoilValue.

useRecoilValue:

Whenever you want to use the value of the state but donโ€™t want to update it in the whole component.
