## Installation
[NPM](https://www.npmjs.com/package/style-to-object):
```sh
npm install style-to-object --save
```
[Yarn](https://yarn.fyi/style-to-object):
```sh
yarn add style-to-object
```
[CDN](https://unpkg.com/style-to-object/):
```html
<script src="https://unpkg.com/style-to-object@latest/dist/style-to-object.min.js"></script>
<script>
window.StyleToObject(/* string */);
</script>
```
## Usage
Import with ES Modules:
```js
import parse from 'style-to-object';
```
Require with CommonJS:
```js
const parse = require('style-to-object').default;
```
Parse single declaration:
```js
parse('line-height: 42');
```
Output:
```js
{ 'line-height': '42' }
```
Parse multiple declarations:
```js
parse(`
border-color: #ACE;
z-index: 1337;
`);
```
Output:
```js
{ 'border-color': '#ACE', 'z-index': '1337' }
```
Parse unknown declarations:
```js
parse('answer: 42;');
```
Output:
```js
{ 'answer': '42' }
```
Invalid declarations/arguments:
<!-- prettier-ignore-start -->
```js
parse(`
top: ;
right: 1em;
`); // { right: '1em' }
parse(); // null
parse(null); // null
parse(1); // null
parse(true); // null
parse('top:'); // null
parse(':12px'); // null
parse(':'); // null
parse(';'); // null
parse('top'); // throws Error
parse('/*'); // throws Error
```
<!-- prettier-ignore-end -->
### Iterator
If the 2nd argument is a function, then the parser will return `null`:
```js
parse('color: #f00', () => {}); // null
```
But the function will iterate through each declaration:
<!-- prettier-ignore-start -->
```js
parse('color: #f00', (name, value, declaration) => {
console.log(name); // 'color'
console.log(value); // '#f00'
console.log(declaration); // { type: 'declaration', property: 'color', value: '#f00' }
});
```
<!-- prettier-ignore-end -->
This makes it easy to customize the output:
```js
const style = `
color: red;
background: blue;
`;
const output = [];
function iterator(name, value) {
output.push([name, value]);
}
parse(style, iterator);
console.log(output); // [['color', 'red'], ['background', 'blue']]
```
## Migration
### v1
Migrated to TypeScript. Iterator excludes `Comment`. CommonJS requires the `.default` key:
```js
const parse = require('style-to-object').default;
```
