## Quick Start
Start with this [CodePen Template](https://codepen.io/pen?template=WOJZdM) to begin prototyping with Feather in the browser.
Or copy and paste the following code snippet into a blank `html` file.
```html
<!DOCTYPE html>
<html lang="en">
<title></title>
<script src="https://unpkg.com/feather-icons/dist/feather.min.js"></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](https://svgontheweb.com/#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](https://svgontheweb.com/#implementation)
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](https://docs.npmjs.com/getting-started/what-is-npm).
```
npm install feather-icons --save
```
Or just copy [`feather.js`](https://unpkg.com/feather-icons/dist/feather.js) or [`feather.min.js`](https://unpkg.com/feather-icons/dist/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. These files are located in the `dist` directory of the npm package.
```html
<script src="path/to/dist/feather.js"></script>
```
Or load the script from a CDN provider.
```html
<!-- choose one -->
<script src="https://cdn.jsdelivr.net/npm/feather-icons/dist/feather.min.js"></script>
<script src="https://unpkg.com/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.
```html
<i data-feather="circle"></i>
```
See the complete list of icons at [feathericons.com](https://feathericons.com).
#### 4. Replace
Call the `feather.replace()` method.
```html
<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](#api-reference) for more information about `feather.replace()`.
### Node
#### 1. Install
Install with [npm](https://docs.npmjs.com/getting-started/what-is-npm).
```
npm install feather-icons --save
```
#### 2. Require
```javascript
const feather = require('feather-icons')
```
#### 3. Use
```js
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',
// }
// }
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](#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](https://docs.npmjs.com/getting-started/what-is-npm).
```
npm install feather-icons --save
```
Or just copy [`feather-sprite.svg`](https://unpkg.com/feather-icons/dist/feather-sprite.svg) into your project directory.
#### 2. Use
In your HTML, you can include an icon like so:
```html
<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](https://feathericons.com).
However, this markup can be simplified using a simple CSS class to avoid repetition of SVG attributes between icons.
```css
.feather {
width: 24px;
height: 24px;
stroke: currentColor;
stroke-width: 2;
stroke-linecap: round;
stroke-linejoin: round;
fill: none;
}
```
```html
<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
```js
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',
// }
// }
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](https://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']`).

### `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. |
#### Usage
```javascript
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>'
```

### `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:
```html
<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:
```html
<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:
```html
<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>
```
