## SVGO [](https://npmjs.org/package/svgo) [](https://discord.gg/z8jX8NYxrE)
|
|
|
|
|
|
**SVG O**ptimizer is a Node.js-based tool for optimizing SVG vector graphics files.
|
|
|
|
|
|
## Why?
|
|
|
|
|
|
SVG files, especially those exported from various editors, usually contain a lot of redundant and useless information. This can include editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting the SVG rendering result.
|
|
|
|
|
|
## Installation
|
|
|
|
|
|
```sh
|
|
|
npm -g install svgo
|
|
|
```
|
|
|
|
|
|
or
|
|
|
|
|
|
```sh
|
|
|
yarn global add svgo
|
|
|
```
|
|
|
|
|
|
## CLI usage
|
|
|
|
|
|
```sh
|
|
|
svgo one.svg two.svg -o one.min.svg two.min.svg
|
|
|
```
|
|
|
|
|
|
Or use the `--folder`/`-f` flag to optimize a whole folder of SVG icons
|
|
|
|
|
|
```sh
|
|
|
svgo -f ./path/to/folder/with/svg/files -o ./path/to/folder/with/svg/output
|
|
|
```
|
|
|
|
|
|
See help for advanced usage
|
|
|
|
|
|
```sh
|
|
|
svgo --help
|
|
|
```
|
|
|
|
|
|
## Configuration
|
|
|
|
|
|
Some options can be configured with CLI though it may be easier to have the configuration in a separate file.
|
|
|
SVGO automatically loads configuration from `svgo.config.js` or module specified with `--config` flag.
|
|
|
|
|
|
```js
|
|
|
module.exports = {
|
|
|
multipass: true, // boolean. false by default
|
|
|
datauri: 'enc', // 'base64', 'enc' or 'unenc'. 'base64' by default
|
|
|
js2svg: {
|
|
|
indent: 2, // string with spaces or number of spaces. 4 by default
|
|
|
pretty: true, // boolean, false by default
|
|
|
},
|
|
|
};
|
|
|
```
|
|
|
|
|
|
SVGO has a plugin-based architecture, so almost every optimization is a separate plugin.
|
|
|
There is a set of [built-in plugins](#built-in-plugins). See how to configure them:
|
|
|
|
|
|
```js
|
|
|
module.exports = {
|
|
|
plugins: [
|
|
|
// enable a built-in plugin by name
|
|
|
'prefixIds',
|
|
|
|
|
|
// or by expanded version
|
|
|
{
|
|
|
name: 'prefixIds',
|
|
|
},
|
|
|
|
|
|
// some plugins allow/require to pass options
|
|
|
{
|
|
|
name: 'prefixIds',
|
|
|
params: {
|
|
|
prefix: 'my-prefix',
|
|
|
},
|
|
|
},
|
|
|
],
|
|
|
};
|
|
|
```
|
|
|
|
|
|
The default preset of plugins is fully overridden if the `plugins` field is specified.
|
|
|
Use `preset-default` plugin to customize plugins options.
|
|
|
|
|
|
```js
|
|
|
module.exports = {
|
|
|
plugins: [
|
|
|
{
|
|
|
name: 'preset-default',
|
|
|
params: {
|
|
|
overrides: {
|
|
|
// customize options for plugins included in preset
|
|
|
inlineStyles: {
|
|
|
onlyMatchedOnce: false,
|
|
|
},
|
|
|
|
|
|
// or disable plugins
|
|
|
removeDoctype: false,
|
|
|
},
|
|
|
},
|
|
|
},
|
|
|
|
|
|
// enable builtin plugin not included in default preset
|
|
|
'prefixIds',
|
|
|
|
|
|
// enable and configure builtin plugin not included in preset
|
|
|
{
|
|
|
name: 'sortAttrs',
|
|
|
params: {
|
|
|
xmlnsOrder: 'alphabetical',
|
|
|
},
|
|
|
},
|
|
|
],
|
|
|
};
|
|
|
```
|
|
|
|
|
|
Default preset includes the following list of plugins:
|
|
|
|
|
|
- removeDoctype
|
|
|
- removeXMLProcInst
|
|
|

|
|
|

|
|
|
- minifyStyles
|
|
|
- cleanupIDs
|
|
|
- removeUselessDefs

|
|
- cleanupNumericValues
|
|
|

|
|
|
- removeUnknownsAndDefaults
|
|
|

|
|
|

|
|
|
- sortDefsChildren
|
|
|
- removeTitle
|
|
|
- removeDesc
|
|
|
|
|
|
It's also possible to specify a custom plugin:
|
|
|
|
|
|
```js
|
|
|
const anotherCustomPlugin = require('./another-custom-plugin.js');
|
|
|
module.exports = {
|
|
|
plugins: [
|
|
|
{
|
|
|
name: 'customPluginName',
|
|
|
type: 'perItem', // 'perItem', 'perItemReverse' or 'full'
|
|
|
params: {
|
|
|
optionName: 'optionValue',
|
|
|
},
|
|
|
fn: (ast, params, info) => {},
|
|
|
},
|
|
|
anotherCustomPlugin,
|
|
|
],
|
|
|
};
|
|
|
```
|
|
|
|
|
|
## API usage
|
|
|
|
|
|
SVGO provides a few low level utilities.
|
|
|
|
|
|
### optimize
|
|
|
|
|
|
The core of SVGO is `optimize` function.
|
|
|
|
|
|
```js
|
|
|
const { optimize } = require('svgo');
|
|
|
const result = optimize(svgString, {
|
|
|
// optional but recommended field
|
|
|
path: 'path-to.svg',
|
|
|
// all config fields are also available here
|
|
|
multipass: true,
|
|
|
});
|
|
|
const optimizedSvgString = result.data;
|
|
|
```
|
|
|
|
|
|
### loadConfig
|
|
|
|
|
|
If you write a tool on top of SVGO you might need a way to load SVGO config.
|
|
|
|
|
|
```js
|
|
|
const { loadConfig } = require('svgo');
|
|
|
const config = await loadConfig();
|
|
|
|
|
|
// you can also specify a relative or absolute path and customize the current working directory
|
|
|
const config = await loadConfig(configFile, cwd);
|
|
|
```
|
|
|
|
|
|
