react-fontawesome-slim v1.0.0

React FontAwesome Slim

Disclaimer

This package exists to let bundle size be smaller. This is not an official package. If you are looking for an official one, please, check here: @fortawesome/react-fontawesome. This library is also created from Eugene Zinovyev's react-fontawesome-svg-icon.

Motivation

Existing @fortawesome/react-fontawesome brings the whole @fortawesome/fontawesome-svg-core into the final bundle, making the bundle size way bigger.

Existing react-fontawesome-svg-icon made by Eugene Zinovyev also had its last update early this year. React 18, launched in late March was not included on its peer list.

This library was made to both support the latest version of React, while also making the bundle size smaller.

How it works

The package uses icon vector data provided by Fontawesome SVG packages (e.g. @fortawesome/free-solid-svg-icons or @fortawesome/free-regular-svg-icons) and styles from @fortawesome/fontawesome-svg-core.

It is important to include styles from @fortawesome/fontawesome-svg-core to the bundle to make it work. Check installation section to more details.

Example

import React from 'react';
import { FontAwesomeSvgIcon } from 'react-fontawesome-svg-icon';
import { faCoffee } from '@fortawesome/free-solid-svg-icons';

const App = () => (
    <FontAwesomeSvgIcon icon={faCoffee} />
);

export default App;
