Icon Libraries Compared: SVG, Fonts, and Framework Integration
When building modern web applications, icons serve as visual anchors that guide users through interfaces. The eight packages we're comparing — bootstrap-icons, feather-icons, font-awesome, heroicons, ionicons, line-awesome, material-icons, and octicons — all solve this problem, but they take different approaches to delivery, customization, and ecosystem integration. Let's examine how each handles common development scenarios.
📦 Installation and Setup Methods
Different packages offer different ways to get icons into your project. Some load from CDN, others bundle with your build, and a few offer both options.
bootstrap-icons installs via npm and offers multiple import methods.
npm install bootstrap-icons
// Import individual SVG
import { Person, House } from 'bootstrap-icons';
// Or use CSS classes with font files
<link rel="stylesheet" href="/bootstrap-icons.css">
<i class="bi bi-person"></i>
feather-icons loads icons dynamically through JavaScript.
npm install feather-icons
import feather from 'feather-icons';
// Replace all <i data-feather> elements
feather.replace();
// Or get specific icon SVG
feather.icons['shopping-cart'].toSvg();
font-awesome offers multiple package options depending on your needs.
npm install @fortawesome/fontawesome-svg-core
npm install @fortawesome/free-solid-svg-icons
npm install @fortawesome/react-fontawesome
import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';
import { faCoffee } from '@fortawesome/free-solid-svg-icons';
<FontAwesomeIcon icon={faCoffee} />
heroicons provides React and Vue components plus raw SVGs.
npm install @heroicons/react
import { BeakerIcon } from '@heroicons/react/24/solid';
<BeakerIcon className="h-6 w-6" />
ionicons works as web components or framework-specific packages.
npm install ionicons
import { addIcons } from 'ionicons';
import { home, settings } from 'ionicons/icons';
addIcons({ home, settings });
// In template
<ion-icon name="home"></ion-icon>
line-awesome uses CSS classes similar to Font Awesome.
npm install line-awesome
<link rel="stylesheet" href="line-awesome/css/line-awesome.min.css">
<i class="las la-coffee"></i>
material-icons loads from Google's CDN or npm package.
npm install material-icons
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
<span class="material-icons">search</span>
octicons provides React components and raw SVGs.
npm install @primer/octicons-react
import { MarkGithubIcon } from '@primer/octicons-react';
<MarkGithubIcon size={24} />
🎨 Customization and Styling Approaches
How you change icon color, size, and appearance varies significantly between packages.
bootstrap-icons uses CSS properties for styling.
.bi-person {
width: 2rem;
height: 2rem;
fill: currentColor;
color: #0d6efd;
}
<i class="bi bi-person" style="font-size: 2rem; color: blue;"></i>
feather-icons accepts attributes during SVG generation.
feather.icons['user'].toSvg({
class: 'icon',
width: 24,
height: 24,
stroke: '#333'
});
font-awesome uses props for React components or CSS classes.
<FontAwesomeIcon
icon={faUser}
size="2x"
color="#333"
rotation={90}
/>
<i class="fas fa-user fa-2x" style="color: #333;"></i>
heroicons passes standard SVG props through components.
<BeakerIcon
className="h-6 w-6 text-blue-500"
strokeWidth={2}
/>
ionicons uses component props for styling.
<ion-icon
name="home"
size="large"
color="primary"
style={{ fontSize: '24px' }}
></ion-icon>
line-awesome relies on CSS classes and properties.
<i class="las la-user la-2x" style="color: #333;"></i>
.la-user {
font-size: 2rem;
color: #0d6efd;
}
material-icons uses CSS classes or ligature text.
<span class="material-icons" style="font-size: 48px; color: red;">favorite</span>
.material-icons {
font-size: 24px;
color: #1976d2;
}
octicons accepts size and fill props.
<MarkGithubIcon
size={32}
fill="#24292e"
className="custom-class"
/>
📱 Framework Integration Patterns
Each package handles React, Vue, and other frameworks differently.
bootstrap-icons works as plain HTML or with framework wrappers.
// React example
function Icon() {
return <i className="bi bi-heart-fill"></i>;
}
feather-icons requires manual initialization in framework lifecycle.
// React useEffect
useEffect(() => {
feather.replace();
}, []);
return <i data-feather="home"></i>;
font-awesome has official components for major frameworks.
// React
import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';
// Vue
import { FontAwesomeIcon } from '@fortawesome/vue-fontawesome';
heroicons offers separate packages for React and Vue.
// React
import { StarIcon } from '@heroicons/react/24/outline';
// Vue
import { StarIcon } from '@heroicons/vue/24/outline';
ionicons provides framework-specific bindings.
// React
import { IonIcon } from '@ionic/react';
// Vue
import { IonIcon } from '@ionic/vue';
line-awesome works as plain CSS without framework dependencies.
// Works in any framework
return <i className="las la-star"></i>;
material-icons functions as web fonts or React components.
// React component
import { Icon } from '@material-ui/core';
<Icon>star</Icon>
octicons has React and Vue packages.
// React
import { GitPullRequestIcon } from '@primer/octicons-react';
// Vue
import { GitPullRequestIcon } from '@primer/octicons-vue';
⚡ Performance and Loading Strategies
How icons load affects your application's initial paint time and runtime performance.
bootstrap-icons allows tree-shaking when importing individual icons.
// Bundle only what you use
import { PersonIcon } from 'bootstrap-icons';
// vs loading entire sprite
feather-icons loads all icons in the initial bundle by default.
// Entire icon set loads
import feather from 'feather-icons';
// Can optimize with individual imports
import { toSvg } from 'feather-icons';
font-awesome supports subsetting to reduce bundle size.
// Import only needed icons
import { faUser } from '@fortawesome/free-solid-svg-icons';
// Or use icon packs
import { fas } from '@fortawesome/free-solid-svg-icons';
heroicons imports are tree-shakeable by default.
// Only BeakerIcon bundles
import { BeakerIcon } from '@heroicons/react/24/solid';
ionicons loads icons on-demand when referenced.
// Icons load when first used
import { addIcons } from 'ionicons';
import { home } from 'ionicons/icons';
addIcons({ home });
line-awesome loads as CSS font file.
/* Single font file contains all icons */
@import 'line-awesome/css/line-awesome.min.css';
material-icons can load from Google Fonts CDN.
<!-- Loads on demand from Google -->
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
octicons supports individual icon imports.
// Tree-shakeable imports
import { SearchIcon } from '@primer/octicons-react';

🔍 The Bottom Line
All eight packages will add icons to your application successfully. The real question isn't which is "best" — it's which fits your specific constraints around design system, licensing, bundle size, and framework choice.
Start with these questions:
- Do you need 200 icons or 2,000+?
- Are you following a specific design system (Material, Bootstrap, custom)?
- Does your budget allow for pro licensing?
- Which frameworks are you using?
- How important is bundle size for your use case?
Answer these honestly, and the right choice becomes clear. For most modern web applications starting today, heroicons (Tailwind projects), bootstrap-icons (Bootstrap projects), or feather-icons (design-focused projects) provide the best balance of quality, licensing, and ease of use.

Install
Bootstrap Icons are packaged up and published to npm. We only include the processed SVGs in this package—it's up to you and your team to implement. Read our docs for usage instructions.
npm i bootstrap-icons
For those using Packagist, you can also install Bootstrap Icons via Composer:
composer require twbs/bootstrap-icons
Usage
Depending on your setup, you can include Bootstrap Icons in a handful of ways.
- Copy-paste SVGs as embedded HTML
- Reference via
<img>element - Use the SVG sprite
- Include via CSS
See the docs for more information.
Development
Clone the repo, install dependencies, and start the Hugo server locally.
git clone https://github.com/twbs/icons/
cd icons
npm i
npm start
Then open http://localhost:4000 in your browser.
npm scripts
Here are some key scripts you'll use during development. Be sure to look to our package.json or npm run output for a complete list of scripts.
| Script | Description |
|---|---|
start | Alias for running docs-serve |
docs-serve | Starts a local Hugo server |
pages | Generates permalink pages for each icon with template Markdown |
icons | Processes and optimizes SVGs in icons directory, generates fonts and sprite |
Adding SVGs
Icons are typically only added by @mdo, but exceptions can be made. New glyphs are designed in Figma first on a 16x16px grid, then exported as flattened SVGs with fill (no stroke). Once a new SVG icon has been added to the icons directory, we use an npm script to:
- Optimize our SVGs with SVGO.
- Modify the SVGs source code, removing all attributes before setting new attributes and values in our preferred order.
Use npm run icons to run the script, run npm run pages to build permalink pages, complete those pages, and, finally, commit the results in a new branch for updating.
Warning: Please exclude any auto-generated files, like font/** and bootstrap-icons.svg from your branch because they cause conflicts, and we generally update the dist files before a release.
Publishing
Documentation is published automatically when a new Git tag is published. See our GitHub Actions and package.json for more information.
