lucide-react

What is lucide-react?

The lucide-react npm package is a collection of open-source icons for React applications. It provides a wide range of customizable SVG icons that can be easily integrated into React projects.

What are lucide-react's main functionalities?

Basic Icon Usage

This feature allows you to import and use a specific icon from the lucide-react package in your React application. The 'name' prop specifies which icon to render.

import { LucideIcon } from 'lucide-react';

function App() {
  return (
    <div>
      <LucideIcon name="home" />
    </div>
  );
}

Customizing Icon Size

You can customize the size of the icons by passing the 'size' prop. This example sets the icon size to 48 pixels.

import { LucideIcon } from 'lucide-react';

function App() {
  return (
    <div>
      <LucideIcon name="home" size={48} />
    </div>
  );
}

Customizing Icon Color

This feature allows you to change the color of the icons by passing the 'color' prop. In this example, the icon color is set to red.

import { LucideIcon } from 'lucide-react';

function App() {
  return (
    <div>
      <LucideIcon name="home" color="red" />
    </div>
  );
}

Installation

yarn add lucide-react

or

npm install lucide-react

How to use

It's built with ES modules so it's completely tree-shakable. Each icon can be imported as a react component.

Example

You can pass additional props to adjust the icon.

import { Camera } from 'lucide-react';

const App = () => {
  return <Camera color="red" size={48} />;
};

export default App;

Props

name	type	default
size	Number	24
color	String	currentColor
strokeWidth	Number	2

Custom props

You can also pass custom props that will be added in the svg as attributes.

const App = () => {
  return <Camera fill="red" />;
};

Generic icon component

It is possible to create a generic icon component to load icons.

:warning: The example below is importing all ES modules. This is not recommended when you using a bundler since your application build size will grow substantially.

import { icons } from 'lucide-react';

const Icon = ({ name, color, size }) => {
  const LucideIcon = icons[name];

  return <LucideIcon color={color} size={size} />;
};

export default Icon;

With Dynamic Imports

Lucide react exports a dynamic import map dynamicIconImports. Useful for applications that want to show icons dynamically by icon name. For example when using a content management system with where icon names are stored in a database.

When using client side rendering, it will fetch the icon component when it's needed. This will reduce the initial bundle size.

The keys of the dynamic import map are the lucide original icon names.

Example with React suspense:

import React, { lazy, Suspense } from 'react';
import { dynamicIconImports, LucideProps } from 'lucide-react';

const fallback = <div style={{ background: '#ddd', width: 24, height: 24 }}/>

interface IconProps extends Omit<LucideProps, 'ref'> {
  name: keyof typeof dynamicIconImports;
}

const Icon = ({ name, ...props }: IconProps) => {
  const LucideIcon = lazy(dynamicIconImports[name]);

  return (
    <Suspense fallback={fallback}>
      <LucideIcon {...props} />
    </Suspense>
  );
}

export default Icon

NextJS Example

In NextJS, the dynamic function can be used to dynamically load the icon component.

To make dynamic imports work with NextJS, you need to add lucide-react to the transpilePackages option in your next.config.js like this:

/** @type {import('next').NextConfig} */
const nextConfig = {
  transpilePackages: ['lucide-react'] // add this
}

module.exports = nextConfig

You can then start using it:

import dynamic from 'next/dynamic'
import { LucideProps } from 'lucide-react';
import dynamicIconImports from 'lucide-react/dynamicIconImports';

interface IconProps extends LucideProps {
  name: keyof typeof dynamicIconImports;
}

const Icon = ({ name, ...props }: IconProps) => {
  const LucideIcon = dynamic(dynamicIconImports[name])

  return <LucideIcon {...props} />;
};

export default Icon;
