postcss-syntax can automatically switch the required [PostCSS](https://github.com/postcss/postcss) syntax by file extension/source
|
|||
|
|
|
|||
|
|
## Getting Started
|
|||
|
|
|
|||
|
|
First thing's first, install the module:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
npm install postcss-syntax --save-dev
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
If you want support SCSS/SASS/LESS/SugarSS syntax, you need to install these module:
|
|||
|
|
|
|||
|
|
- SCSS: [postcss-scss](https://github.com/postcss/postcss-scss)
|
|||
|
|
- SASS: [postcss-sass](https://github.com/aleshaoleg/postcss-sass)
|
|||
|
|
- LESS: [postcss-less](https://github.com/shellscape/postcss-less)
|
|||
|
|
- SugarSS: [sugarss](https://github.com/postcss/sugarss)
|
|||
|
|
|
|||
|
|
If you want support HTML (and HTML-like)/Markdown/CSS-in-JS file format, you need to install these module:
|
|||
|
|
|
|||
|
|
- CSS-in-JS: [postcss-jsx](https://github.com/gucong3000/postcss-jsx)
|
|||
|
|
- HTML (and HTML-like): [postcss-html](https://github.com/gucong3000/postcss-html)
|
|||
|
|
- Markdown: [postcss-markdown](https://github.com/gucong3000/postcss-markdown)
|
|||
|
|
|
|||
|
|

postcss(plugins).process(source, { syntax: syntax }).then(function (result) {
