SCSS Parser

Getting Started

let { parse, stringify } = require('scss-parser')

// Create an AST from a string of SCSS
let ast = parse('.hello { color: $red; }')
// Modify the AST (see below for a better way to do this)
ast.value[0].value[0].value[0].value[0].value = 'world'
// Convert the modified AST back to SCSS
let scss = stringify(ast) // .world { color: $red; }

Traversal

For an easy way to traverse/modify the generated AST, check out QueryAST

let { parse, stringify } = require('scss-parser')
let createQueryWrapper = require('query-ast')

// Create an AST
let ast = parse('.hello { color: red; } .world { color: blue; }')
// Create a function to traverse/modify the AST
let $ = createQueryWrapper(ast)
// Make some modifications
$('rule').eq(1).remove()
// Convert the modified AST back to a string
let scss = stringify($().get(0))
