sassOptions

sassOptions allow you to configure the Sass compiler.

importtype { NextConfig }from'next'constsassOptions= {  additionalData:`    $var: red;  `,}constnextConfig:NextConfig= {  sassOptions: {...sassOptions,    implementation:'sass-embedded',  },}exportdefault nextConfig

Good to know:

• sassOptions are not typed outside ofimplementation because Next.js does not maintain the other possible properties.
• Thefunctions 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.
