Hi Friends 👋,

Welcome To aGuideHub!

To install and use lodash in React js, you have to use the npm or yarn package manager that is how you can install the lodash library into your project.

Lodash provides you with a set of ready to use functions created to operate or modify JavaScript data structures like arrays, numbers, objects, strings, and the rest.

Today, I am going to show you, how to install and use lodash in react js.

• Set up the React project.

• Use lodash.

Step 1: Set up the React project.

First you have to install the React project. You should use create-react-app command to create a new React project.

npx create-react-app my-app
cd my-app
npm start

Step 2: Import necessary components.

After installing lodash, you have to import your React component. To do this, add the following line to the top of your component file.

import React from 'react'
import { IsEmpty, Map } from "react-lodash";

Step 3: Use lodash.

Here’s an example of conditional rendering by using Lodash’s isEmpty and map functions.

<IsEmpty
  value={dailyExpenses}
  yes="Empty list"
  no={() => (
    <ul>
      <Map collection={dailyExpenses} iteratee={i => <li key={i}>{i}</li>} />
    </ul>
  )}
/>

React lodash example.

The code below is an example of this, There’s also a neat package called react-lodash that transforms Lodash utility functions into React components. Here’s an example of conditional rendering by using Lodash’s isEmpty and map functions.

App.js

import React from 'react'
import { IsEmpty, Map } from "react-lodash";

export default function App() {
  const dailyExpenses = [0, 1, 2, 3, 5, 6, 7, 8, 9];
  return (
    <IsEmpty
      value={dailyExpenses}
      yes="Empty list"
      no={() => (
        <ul>
          <Map collection={dailyExpenses} iteratee={i => <li key={i}>{i}</li>} />
        </ul>
      )}
    />
  );
}
