# Custom runtime generating example
|
||
|
|
|
||
|
|
Runtime code generated by loader could be overridden by providing custom generator via `runtimeGenerator` option.
|
||
|
|
For example you can return React component preconfigured with imported symbol data instead of default [symbol instance](https://github.com/kisenka/svg-baker/blob/master/packages/svg-baker-runtime/src/symbol.js).
|
||
|
|
|
||
|
|
### [Demo](demo.html)
|
||
|
|
|
||
|
|
### Config
|
||
|
|
|
||
|
|
- [webpack.config.js](webpack.config.js)
|
||
|
|
- [svg-to-icon-component-runtime-generator.js](svg-to-icon-component-runtime-generator.js)
|
||
|
|
|
||
|
|
### Input
|
||
|
|
|
||
|
|
- [main.jsx](main.jsx)
|
||
|
|
- [icon.jsx](icon.jsx)
|
||
|
|
|
||
|
|
This import:
|
||
|
|
|
||
|
|
```js
|
||
|
|
import TwitterIcon from '../assets/twitter.svg';
|
||
|
|
```
|
||
|
|
|
||
|
|
Will be generated to:
|
||
|
|
|
||
|
|
```js
|
||
|
|
import React from 'react';
|
||
|
|
import SpriteSymbol from 'svg-sprite-loader/runtime/symbol';
|
||
|
|
import sprite from 'svg-sprite-loader/runtime/browser-sprite';
|
||
|
|
import SpriteSymbolComponent from './icon.jsx';
|
||
|
|
|
||
|
|
const symbol = new SpriteSymbol({ /* symbol data */ });
|
||
|
|
sprite.add(symbol);
|
||
|
|
|
||
|
|
export default class TwitterIcon extends React.Component {
|
||
|
|
render() {
|
||
|
|
return <SpriteSymbolComponent glyph="${symbol.id}" {...this.props} />;
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
So when you import SVG, actually React component returns with configured glyph:
|
||
|
|
|
||
|
|
```js
|
||
|
|
import TwitterIcon from '../assets/twitter.svg';
|
||
|
|
|
||
|
|
render(
|
||
|
|
<div>
|
||
|
|
<TwitterIcon width="100" />
|
||
|
|
<TwitterIcon fill="red" style={{width: 300}} />
|
||
|
|
<TwitterIcon fill="blue" style={{width: 600}} />
|
||
|
|
</div>,
|
||
|
|
document.querySelector('.app')
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
### Output
|
||
|
|
|
||
|
|
- [build/main.js](build/main.js)
|
