Quick Start

Start with this CodePen Template to begin prototyping with Feather in the browser.

Or copy and paste the following code snippet into a blank html file.

<!DOCTYPE html>
<html lang="en">
  <title></title>
  <script src="https://unpkg.com/feather-icons"></script>
  <body>

    <!-- example icon -->
    <i data-feather="circle"></i>

    <script>
      feather.replace()
    </script>
  </body>
</html>

Usage

At its core, Feather is a collection of SVG files. This means that you can use Feather icons in all the same ways you can use SVGs (e.g. img, background-image, inline, object, embed, iframe). Here's a helpful article detailing the many ways SVGs can be used on the web: SVG on the Web – Implementation Options

The following are additional ways you can use Feather.

Client-side JavaScript

1. Install

Note: If you intend to use Feather with a CDN, you can skip this installation step.

Install with npm.

npm install feather-icons --save

Or just copy feather.js or feather.min.js into your project directory. You don't need both feather.js and feather.min.js.

2. Include

Include feather.js or feather.min.js with a <script> tag:

<script src="path/to/dist/feather.js"></script>

Note: feather.js and feather.min.js are located in the dist directory of the npm package.

Or load the script from a CDN provider:

<!-- choose one -->
<script src="https://unpkg.com/feather-icons"></script>
<script src="https://cdn.jsdelivr.net/npm/feather-icons/dist/feather.min.js"></script>

After including the script, feather will be available as a global variable.

3. Use

To use an icon on your page, add a data-feather attribute with the icon name to an element:

<i data-feather="circle"></i>

See the complete list of icons at feathericons.com.

4. Replace

Call the feather.replace() method:

<script>
  feather.replace()
</script>

All elements that have a data-feather attribute will be replaced with SVG markup corresponding to their data-feather attribute value. See the API Reference for more information about feather.replace().

Node

1. Install

Install with npm:

npm install feather-icons --save

2. Require

const feather = require('feather-icons')

3. Use

feather.icons.x
// {
//    name: 'x',
//    contents: '<line ... /><line ... />`,
//    tags: ['cancel', 'close', 'delete', 'remove'],
//    attrs: {
//      class: 'feather feather-x',
//      xmlns: 'http://www.w3.org/2000/svg',
//      width: 24,
//      height: 24,
//      viewBox: '0 0 24 24',
//      fill: 'none',
//      stroke: 'currentColor',
//      'stroke-width': 2,
//      'stroke-linecap': 'round',
//      'stroke-linejoin': 'round',
//    },
//    toSvg: [Function],
// }

feather.icons.x.toSvg()
// <svg class="feather feather-x" ...><line ... /><line ... /></svg>

feather.icons.x.toSvg({ class: 'foo bar', 'stroke-width': 1, color: 'red' })
// <svg class="feather feather-x foo bar" stroke-width="1" color="red" ...><line ... /><line ... /></svg>

See the API Reference for more information about the available properties and methods of the feather object.

SVG Sprite

1. Install

Note: If you intend to use Feather with a CDN, you can skip this installation step.

Install with npm.

npm install feather-icons --save

Or just copy feather-sprite.svg into your project directory.

2. Use

Include an icon on your page with the following markup:

<svg
  width="24"
  height="24"
  fill="none"
  stroke="currentColor"
  stroke-width="2"
  stroke-linecap="round"
  stroke-linejoin="round"
>
  <use xlink:href="path/to/feather-sprite.svg#circle"/>
</svg>

Note: circle in the above example can be replaced with any valid icon name. See the complete list of icon names at feathericons.com.

However, this markup can be simplified using a simple CSS class to avoid repetition of SVG attributes between icons:

.feather {
  width: 24px;
  height: 24px;
  stroke: currentColor;
  stroke-width: 2;
  stroke-linecap: round;
  stroke-linejoin: round;
  fill: none;
}

<svg class="feather">
  <use xlink:href="path/to/dist/feather-sprite.svg#circle"/>
</svg>

API Reference

`feather.icons`

An object with data about every icon.

Usage

feather.icons.x
// {
//    name: 'x',
//    contents: '<line ... /><line ... />',
//    tags: ['cancel', 'close', 'delete', 'remove'],
//    attrs: {
//      class: 'feather feather-x',
//      xmlns: 'http://www.w3.org/2000/svg',
//      width: 24,
//      height: 24,
//      viewBox: '0 0 24 24',
//      fill: 'none',
//      stroke: 'currentColor',
//      'stroke-width': 2,
//      'stroke-linecap': 'round',
//      'stroke-linejoin': 'round',
//    },
//    toSvg: [Function],
// }

feather.icons.x.toString()
// '<line ... /><line ... />'

Note: x in the above example can be replaced with any valid icon name. See the complete list of icon names at feathericons.com. Icons with multi-word names (e.g. arrow-right) cannot be accessed using dot notation (e.g. feather.icons.x). Instead, use bracket notation (e.g. feather.icons['arrow-right']).

View Source

`feather.icons[name].toSvg([attrs])`

Returns an SVG string.

Parameters

Name	Type	Description
`attrs` (optional)	Object	Key-value pairs in the `attrs` object will be mapped to HTML attributes on the `<svg>` tag (e.g. `{ foo: 'bar' }` maps to `foo="bar"`). All default attributes on the `<svg>` tag can be overridden with the `attrs` object.

Hint: You might find these SVG attributes helpful for manipulating icons:

color

width

height

stroke-width

stroke-linecap

stroke-linejoin

Usage

feather.icons.circle.toSvg()
// '<svg class="feather feather-circle" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"></circle></svg>'

feather.icons.circle.toSvg({ 'stroke-width': 1 })
// '<svg class="feather feather-circle" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="1" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"></circle></svg>'

feather.icons.circle.toSvg({ class: 'foo bar' })
// '<svg class="feather feather-circle foo bar" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"></circle></svg>'

View Source

`feather.replace([attrs])`

Replaces all elements that have a data-feather attribute with SVG markup corresponding to the element's data-feather attribute value.

Parameters

Name	Type	Description
`attrs` (optional)	Object	Key-value pairs in the `attrs` object will be mapped to HTML attributes on the `<svg>` tag (e.g. `{ foo: 'bar' }` maps to `foo="bar"`). All default attributes on the `<svg>` tag can be overridden with the `attrs` object.

Usage

Note: feather.replace() only works in a browser environment.

Simple usage:

<i data-feather="circle"></i>
<!--
<i> will be replaced with:
<svg class="feather feather-circle" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"></circle></svg>
-->

<script>
  feather.replace()
</script>

You can pass feather.replace() an attrs object:

<i data-feather="circle"></i>
<!--
<i> will be replaced with:
<svg class="feather feather-circle foo bar" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="1" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"></circle></svg>
-->

<script>
  feather.replace({ class: 'foo bar', 'stroke-width': 1 })
</script>

All attributes on the placeholder element (i.e. <i>) will be copied to the <svg> tag:

<i data-feather="circle" id="my-circle" class="foo bar" stroke-width="1"></i>
<!--
<i> will be replaced with:
<svg id="my-circle" class="feather feather-circle foo bar" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="1" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"></circle></svg>
-->

<script>
  feather.replace()
</script>
