LAIS Icons React

Implementation of the lais icon library for react applications.

What is lais icons? Read it here.

Installation

yarn add @lais_ufrn/icons-react

or

npm install @lais_ufr/icons-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 { Virus } from '@lais_ufr/icons-react';

const App = () => {
  return <Virus 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 <Virus 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 '@lais_ufrn/icons-react';

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

  return <LaisIcon 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 { LaisProps } from '@lais_ufrn/icons-react';
import dynamicIconImports from '@lais_ufrn/dynamicIconImports';

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

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

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

  return (
    <Suspense fallback={fallback}>
      <LaisIcon {...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: ['@lais_ufrn/icons-react'] // add this
}

module.exports = nextConfig

You can then start using it:

import dynamic from 'next/dynamic'
import { LaisProps } from '@lais_ufrn/icons-reactt';
import dynamicIconImports from '@lais_ufrn/dynamicIconImports';

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

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

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

export default Icon;
