sassOptions

sassOptions allow you to configure the Sass compiler.

import type { NextConfig } from 'next'

const sassOptions = {
  additionalData: `
    $var: red;
  `,
}

const nextConfig: NextConfig = {
  sassOptions: {
    ...sassOptions,
    implementation: 'sass-embedded',
  },
}

export default nextConfig

/** @type {import('next').NextConfig} */

const sassOptions = {
  additionalData: `
    $var: red;
  `,
}

const nextConfig = {
  sassOptions: {
    ...sassOptions,
    implementation: 'sass-embedded',
  },
}

module.exports = nextConfig

Good to know:

• sassOptions are not typed outside of implementation because Next.js does not maintain the other possible properties.
• The functions property for defining custom Sass functions is only supported with webpack. When using Turbopack, custom Sass functions are not available because Turbopack’s Rust-based architecture cannot directly execute JavaScript functions passed through this option.
