|
|
|
|
> Optimise inline SVG with PostCSS.
|
|
|
|
|
|
## Install
|
|
|
|
With [npm](https://npmjs.org/package/postcss-svgo) do:
|
|
|
|
```
|
|
npm install postcss-svgo --save
|
|
```
|
|
|
|
|
|
## Example
|
|
|
|
### Input
|
|
|
|
```css
|
|
h1 {
|
|
background: url('data:image/svg+xml;charset=utf-8,<?xml version="1.0" encoding="utf-8"?><!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"><svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xml:space="preserve"><circle cx="50" cy="50" r="40" fill="yellow" /></svg>');
|
|
}
|
|
```
|
|
|
|
### Output
|
|
|
|
```css
|
|
h1 {
|
|
background: url('data:image/svg+xml;charset=utf-8,<svg xmlns="http://www.w3.org/2000/svg"><circle cx="50" cy="50" r="40" fill="%23ff0"/></svg>');
|
|
}
|
|
```
|
|
|
|
|
|
## API
|
|
|
|
### `svgo([options])`
|
|
|
|
Note that postcss-svgo is an *asynchronous* processor. It cannot be used
|
|
like this:
|
|
|
|
```js
|
|
var result = postcss([ svgo() ]).process(css).css;
|
|
console.log(result);
|
|
```
|
|
|
|
Instead make sure your PostCSS runner uses the asynchronous API:
|
|
|
|
```js
|
|
postcss([ svgo() ]).process(css).then(function (result) {
|
|
console.log(result.css);
|
|
});
|
|
```
|
|
|
|
#### options
|
|
|
|
##### encode
|
|
|
|
Type: `boolean`
|
|
Default: `undefined`
|
|
|
|
If `true`, it will encode URL-unsafe characters such as `<`, `>` and `&`;
|
|
`false` will decode these characters, and `undefined` will neither encode nor
|
|
decode the original input. Note that regardless of this setting, `#` will
|
|
always be URL-encoded.
|
|
|
|
##### plugins
|
|
|
|
Optionally, you can customise the output by specifying the `plugins` option. You
|
|
will need to provide the config in comma separated objects, like the example
|
|
below. Note that you can either disable the plugin by setting it to `false`,
|
|
or pass different options to change the default behaviour.
|
|
|
|
```js
|
|
var postcss = require('postcss');
|
|
var svgo = require('postcss-svgo');
|
|
|
|
var opts = {
|
|
plugins: [{
|
|
removeDoctype: false
|
|
}, {
|
|
removeComments: false
|
|
}, {
|
|
cleanupNumericValues: {
|
|
floatPrecision: 2
|
|
}
|
|
}, {
|
|
convertColors: {
|
|
names2hex: false,
|
|
rgb2hex: false
|
|
}
|
|
}]
|
|
};
|
|
|
|
postcss([ svgo(opts) ]).process(css).then(function (result) {
|
|
console.log(result.css)
|
|
});
|
|
```
|
|
|
|
