React Hooks have revolutionized the way developers write code in React applications. They allow for a more declarative and concise approach to handling stateful logic in functional components. The npm package react-hooks-lib provides a collection of commonly used hooks that can be easily integrated into your React projects. In this tutorial, we will explore the react-hooks-lib package and learn how to use some of its most useful hooks.
Installing react-hooks-lib
To get started with react-hooks-lib, you first need to install it as a dependency in your project using npm or yarn:
npm install react-hooks-lib
or
yarn add react-hooks-lib
Once installed, you can import any hook from the package like so:
import { useToggle } from 'react-hooks-lib';Using the useToggle Hook
One of the most commonly used hooks in react-hooks-lib is useToggle. This hook allows you to easily toggle a boolean value between true and false, which can be useful in many scenarios. Let's take a look at an example:
-- -------------------- ---- -------
------ - --------- - ---- ------------------
-------- ------------- -
----- ------ ----------- - -----------------
------ -
-----
------- ---------------------
----- - ---- - ------

-In this example, we import the useToggle hook from react-hooks-lib. We then use it within our MyComponent function to define a state variable isOn and a function toggleIsOn to update it. When the button is clicked, the toggleIsOn function is called, which toggles the value of isOn between true and false. The text of the button changes depending on the value of isOn.
Using the useLocalStorage Hook
Another useful hook in react-hooks-lib is useLocalStorage. This hook allows you to easily store and retrieve values from local storage, which can be helpful when persisting user settings or preferences. Here's an example:
-- -------------------- ---- -------
------ - --------------- - ---- ------------------
-------- ------------- -
----- ------ -------- - ----------------------- ----
------ -
-----

-In this example, we import the useLocalStorage hook from react-hooks-lib. We then use it within our MyComponent function to define a state variable name and a function setName to update it. The useLocalStorage hook accepts two parameters: the key to use for storing the value in local storage, and the initial value to use if no value exists in local storage. When the input field is updated, the setName function is called to update the name state variable and also store it in local storage.
Conclusion
In this tutorial, we have explored the react-hooks-lib package and learned how to use some of its most useful hooks. We covered the useToggle hook for easily toggling boolean values, as well as the useLocalStorage hook for persisting data in local storage. By leveraging these hooks, you can write more concise and readable code in your React applications.
