|
|
|
|
Vue-Awesome an SVG icon component for [Vue.js](https://vuejs.org/), with built-in icons courtesy of [Font Awesome](https://fontawesome.com/).
|
|
|
|
Check out the demo [here](https://justineo.github.io/vue-awesome/demo/).
|
|
|
|
## Installation
|
|
|
|
### npm (Recommended)
|
|
|
|
```bash
|
|
$ npm install vue-awesome
|
|
```
|
|
|
|
### bower
|
|
|
|
```bash
|
|
$ bower install vue-awesome
|
|
```
|
|
|
|
### Manual
|
|
|
|
Just download `dist/vue-awesome.js` and include it in your HTML file:
|
|
|
|
```html
|
|
<script src="path/to/vue-awesome/dist/vue-awesome.js"></script>
|
|
```
|
|
|
|
## Usage
|
|
|
|
```html
|
|
<!-- basic -->
|
|
<v-icon name="beer"/>
|
|
|
|
<!-- with options -->
|
|
<v-icon name="sync" scale="2" spin/>
|
|
<v-icon name="comment" flip="horizontal"/>
|
|
<v-icon name="code-branch" label="Forked Repository"/>
|
|
|
|
<!-- stacked icons -->
|
|
<v-icon label="No Photos">
|
|
<v-icon name="camera"/>
|
|
<v-icon name="ban" scale="2" class="alert"/>
|
|
</v-icon>
|
|
```
|
|
|
|
Font Awesome 5 has separated all icons into several packs. Vue-Awesome is built upon its all free icons, which includes all free icons from 3 icon packs: `regular`, `solid` and `brands`. Since the `solid` pack has the most number of icons, we organize all Vue-Awesome icons as follows:
|
|
|
|
* All icons from `solid` pack are located in `vue-awesome/icons` directory and have unprefixed `name` prop values.
|
|
|
|
* Icons from `regular` and `brands` are located in `vue-awesome/icons/regular` and `vue-awesome/icons/brands`, which have prefixed `name` prop values like `regular/flag` or `brands/reddit`.
|
|
|
|
You can find all available `name` values from [Font Awesome's website](https://fontawesome.com/icons) like `beer`, `file` and `camera`.
|
|
|
|
### ES Modules with NPM & vue-loader (Recommended)
|
|
|
|
```js
|
|
import Vue from 'vue'
|
|
|
|
/* Pick one way between the 2 following ways */
|
|
|
|
// only import the icons you use to reduce bundle size
|
|
import 'vue-awesome/icons/flag'
|
|
|
|
// or import all icons if you don't care about bundle size
|
|
import 'vue-awesome/icons'
|
|
|
|
/* Register component with one of 2 methods */
|
|
|
|
import Icon from 'vue-awesome/components/Icon'
|
|
|
|
// globally (in your main .js file)
|
|
Vue.component('v-icon', Icon)
|
|
|
|
// or locally (in your component file)
|
|
export default {
|
|
components: {
|
|
'v-icon': Icon
|
|
}
|
|
}
|
|
```
|
|
|
|
#### ⚠️ Heads up
|
|
|
|
##### Importing the souce version
|
|
|
|
If you are using official Vue CLI to create your project and you want to use the untranspiled component (import `vue-awesome/components/Icon` rather than import `vue-awesome` directly, to optimize bundle size, which is recommended), you'll encounter the problem that the default configuration will exclude `node_modules` from files to be transpiled by Babel.
|
|
|
|
For **Vue CLI 3+**, add `vue-awesome` into `transpileDependencies` in `vue.config.js` like this:
|
|
|
|
```js
|
|
// vue.config.js
|
|
module.exports = {
|
|
transpileDependencies: [
|
|
/\bvue-awesome\b/
|
|
]
|
|
}
|
|
```
|
|
|
|
For **Vue CLI 2** with the `webpack` template, modify `build/webpack.base.conf.js` like this:
|
|
|
|
```diff
|
|
{
|
|
test: /\.js$/,
|
|
loader: 'babel-loader',
|
|
- include: [resolve('src'), resolve('test')]
|
|
+ include: [
|
|
+ resolve('src'),
|
|
+ resolve('test'),
|
|
+ resolve('node_modules/vue-awesome')
|
|
+ ]
|
|
}
|
|
```
|
|
|
|
If you are using bare webpack config, just do similar modifications make it work.
|
|
|
|
#### Using with Nuxt.js
|
|
|
|
When using Vue-Awesome on the server side with Nuxt.js, it may prompt `Unexpected token import` because Nuxt.js has configured an `external` option by default, which prevent files under `node_modules` from being bundled into the server bundle with only a few exceptions. We need to whitelist `vue-awesome` in `nuxt.config.js` as follows:
|
|
|
|
For **Nuxt.js 2**:
|
|
|
|
```js
|
|
|
|
module.exports = {
|
|
// ...
|
|
build: {
|
|
transpile: [/^vue-awesome/]
|
|
}
|
|
}
|
|
```
|
|
|
|
For **Nuxt.js 1**:
|
|
|
|
```js
|
|
// Don't forget to
|
|
// npm i --save-dev webpack-node-externals
|
|
const nodeExternals = require('webpack-node-externals')
|
|
|
|
module.exports = {
|
|
// ...
|
|
build: {
|
|
extend (config, { isServer }) {
|
|
// ...
|
|
if (isServer) {
|
|
config.externals = [
|
|
nodeExternals({
|
|
// default value for `whitelist` is
|
|
// [/es6-promise|\.(?!(?:js|json)$).{1,5}$/i]
|
|
whitelist: [/es6-promise|\.(?!(?:js|json)$).{1,5}$/i, /^vue-awesome/]
|
|
})
|
|
]
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
##### Unit Testing with Jest
|
|
|
|
Make sure to whitelist `vue-awesome` from the `transformIgnorePattern`. Add following configuation in `test/unit/jest.conf.js`:
|
|
|
|
```diff
|
|
+ transformIgnorePatterns: [
|
|
+ '/node_modules(?![\\\\/]vue-awesome[\\\\/])/'
|
|
+ ],
|
|
```
|
|
|
|
*Don't import all icons if you don't want to make unit testing slow because this will transform all icons from ES module and thus slow down the test process.*
|
|
|
|
### CommonJS with NPM without ES Next support
|
|
|
|
```js
|
|
var Vue = require('vue')
|
|
|
|
// requiring the UMD module
|
|
var Icon = require('vue-awesome')
|
|
|
|
// or with vue-loader you can require the src directly
|
|
var Icon = require('vue-awesome/components/Icon')
|
|
|
|
// register component to use
|
|
```
|
|
|
|
### AMD
|
|
|
|
```js
|
|
require.config({
|
|
paths: {
|
|
'vue-awesome': 'path/to/vue-awesome'
|
|
}
|
|
})
|
|
|
|
require(['vue-awesome'], function (Icon) {
|
|
// register component to use
|
|
Vue.component('v-icon', Icon)
|
|
})
|
|
```
|
|
|
|
### Global variable
|
|
|
|
The component class is exposed as `window.VueAwesome`.
|
|
|
|
```js
|
|
// register component to use
|
|
Vue.component('v-icon', VueAwesome)
|
|
```
|
|
|
|
### Props
|
|
|
|
* `name: string`
|
|
|
|
The name of the icon. It's necessary if the component isn't used as the wrapper of an icon stack. All valid names correspond to the file path relative to the `icons` directory. Notice that you may have to check the name of the icon pack after you search on FontAwesome's website. For example, you'll see a URL argument of `style=brands` on the [detail page for `500px`](https://fontawesome.com/icons/500px?style=brands) and the icon name will be `brands/500px`.
|
|
|
|
Only free icons for FontAwesome are available by default and because the `solid` style has the most icons, we've made it the default pack so the path prefixes can be omitted.
|
|
|
|
If you pass `null` to this prop, the whole component will not be rendered.
|
|
|
|
* `scale: number|string`
|
|
|
|
Used to adjust the size of the icon. Default to `1`.
|
|
|
|
* `spin: boolean`
|
|
|
|
Used to specify whether the icon is spining. Default to `false`. (Can't use together with `pulse`.)
|
|
|
|
* `pulse: boolean`
|
|
|
|
Set the pulse effect to the icon. Default to `false`. (Can't use together with `spin`.)
|
|
|
|
* `inverse: boolean`
|
|
|
|
If set to `true`, the color of the icon will become `#fff`. Default to `false`.
|
|
|
|
* `flip: 'vertical'|'horizontal'|'both'`
|
|
|
|
Used to flip the icon.
|
|
|
|
* `label: string`
|
|
|
|
Set the `aria-label` for the icon if provided.
|
|
|
|
* `title: string`
|
|
|
|
Set the title for the icon.
|
|
|
|
> The icon will have `role="presentation"` thus not accessible when neither `label` nor `title` exists.
|
|
|
|
### Misc
|
|
|
|
If you are using `vue-awesome/components/Icon` (instead of the whole bundled version), Vue-Awesome won't import a single icon by default. Do not forget to import icons you want to use.
|
|
|
|
If these caveats don't help and there are no proper workarounds in [earlier issues](https://github.com/Justineo/vue-awesome/issues?utf8=%E2%9C%93&q=is%3Aissue), please feel free to [file a new one](https://github.com/Justineo/vue-awesome/issues/new).
|
|
|
|
## Styling
|
|
|
|
### Dynamic sizing
|
|
|
|
You can make the icons scale dynamically according to your `font-size` by adding the following CSS:
|
|
|
|
```css
|
|
.fa-icon {
|
|
width: auto;
|
|
height: 1em; /* or any other relative font sizes */
|
|
|
|
/* You would have to include the following two lines to make this work in Safari */
|
|
max-width: 100%;
|
|
max-height: 100%;
|
|
}
|
|
```
|
|
|
|
### Colors
|
|
|
|
The icon color is inherited from the font color of the parent element by default. You can easily change it to any other color by specifying the `color` property.
|
|
|
|
## Local development
|
|
|
|
```bash
|
|
$ npm i
|
|
$ npm run dev
|
|
```
|
|
|
|
Open `http://localhost:8080/demo` to see the demo.
|
|
|
|
### Updating icons
|
|
|
|
Don't touch files in `src/icons` but update `assets/svg/*` instead and run `npm run icons` to re-generate icon module files.
|
|
|
|
## Registering custom icons
|
|
|
|
### Simple case
|
|
|
|
You can register custom icons like this:
|
|
|
|
```js
|
|
import Icon from 'vue-awesome/components/Icon'
|
|
|
|
Icon.register({
|
|
baidu: {
|
|
width: 23.868,
|
|
height: 26,
|
|

|
|
}
|
|
})
|
|
```
|
|
|
|
### More advanced cases
|
|
|
|
If your SVG file has more than one path or polygon, and/or you want to have a predefined style, you can register like this:
|
|
|
|
#### Paths
|
|
|
|
```js
|
|
import Icon from 'vue-awesome/components/Icon'
|
|
|
|
Icon.register({
|
|
webpack: {
|
|
width: 1200,

|
|
}
|
|
]
|
|
}
|
|
})
|
|
```
|
|
|
|
#### Polygons
|
|
|
|
```js
|
|
import Icon from 'vue-awesome/components/Icon'
|
|
|
|
Icon.register({
|
|
vue: {
|
|
width: 256,
|
|
height: 221,
|
|
polygons: [
|
|
{
|
|
style: 'fill:#41B883',
|
|
points: '0,0 128,220.8 256,0 204.8,0 128,132.48 50.56,0 0,0'
|

|
|
}
|
|
]
|
|
}
|
|
})
|
|
```
|
|
|
|
#### Raw SVG
|
|
|
|
**If you are using Vue.js version prior to `2.6.0`, you need to include [innersvg-polyfill](https://www.npmjs.com/package/svg-innerhtml) before you use this feature.**
|
|
|
|
```js
|
|
import Icon from 'vue-awesome/components/Icon'
|
|
|
|
Icon.register({
|
|
'html5-c': {
|
|
width: 512,
|
|
height: 512,
|
|
raw: '<path fill="#E34F26" d="M71,460 L30,0 481,0 440,460 255,512"/><path fill="#EF652A" d="M256,472 L405,431 440,37 256,37"/><path fill="#EBEBEB" d="M256,208 L181,208 176,150 256,150 256,94 255,94 114,94 115,109 129,265 256,265zM256,355 L255,355 192,338 188,293 158,293 132,293 139,382 255,414 256,414z"/><path fill="#FFF" d="M255,208 L255,265 325,265 318,338 255,355 255,414 371,382 372,372 385,223 387,208 371,208zM255,94 L255,129 255,150 255,150 392,150 392,150 392,150 393,138 396,109 397,94z"/>'
|
|
}
|
|
})
|
|
```
|
