render

render(options: LegacyOptions<"async">, callback: ((exception?: LegacyException, result?: LegacyResult) => void)): void
This function asynchronously compiles a Sass file to CSS, and calls callback with a LegacyResult if compilation succeeds or LegacyException if it fails.

⚠️ Heads up!

When using Dart Sass, renderSync is almost twice as fast as render by default, due to the overhead of making the entire evaluation process asynchronous.
```
const sass = require('sass'); // or require('node-sass');

sass.render({
  file: "style.scss"
}, function(err, result) {
  // ...
});
```
Deprecated
Use compileAsync or compileStringAsync instead.
