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)
|
||
|
||
## Use Cases
|
||
|
||
```js
|
||
const postcss = require('postcss');
|
||
const syntax = require('postcss-syntax')({
|
||
rules: [
|
||
{
|
||
test: /\.(?:[sx]?html?|[sx]ht|vue|ux|php)$/i,
|
||
extract: 'html',
|
||
},
|
||
{
|
||
test: /\.(?:markdown|md)$/i,
|
||
extract: 'markdown',
|
||
},
|
||
{
|
||
test: /\.(?:m?[jt]sx?|es\d*|pac)$/i,
|
||
extract: 'jsx',
|
||
},
|
||
{
|
||
// custom language for file extension
|
||
test: /\.postcss$/i,
|
||
lang: 'scss'
|
||
},
|
||
{
|
||
// custom language for file extension
|
||
test: /\.customcss$/i,
|
||
lang: 'custom'
|
||
},
|
||
],
|
||
|
||
// custom parser for CSS (using `postcss-safe-parser`)
|
||
css: 'postcss-safe-parser',
|
||
// custom parser for SASS (PostCSS-compatible syntax.)
|
||
sass: require('postcss-sass'),
|
||
// custom parser for SCSS (by module name)
|
||
scss: 'postcss-scss',
|
||
// custom parser for LESS (by module path)
|
||
less: './node_modules/postcss-less',
|
||
// custom parser for SugarSS
|
||
sugarss: require('sugarss'),
|
||
// custom parser for custom language
|
||
custom: require('postcss-custom-syntax'),
|
||
|
||
});
|
||
postcss(plugins).process(source, { syntax: syntax }).then(function (result) {
|
||
// An alias for the result.css property. Use it with syntaxes that generate non-CSS output.
|
||
result.content
|
||
});
|
||
```
