    Asynchronously compiles a stylesheet whose contents is source to CSS. Returns a promise that resolves with a CompileResult if it succeeds and rejects with an Exception if it fails.

    This only allows synchronous or asynchronous Importers and CustomFunctions.

    ⚠️ Heads up!

    When using the sass npm package, compileString is almost twice as fast as compileStringAsync, due to the overhead of making the entire evaluation process asynchronous.


    const sass = require('sass');

    const result = await sass.compileStringAsync(`
    h1 {
    font-size: 40px;
    code {
    font-face: Roboto Mono;


    Returns Promise<CompileResult>
