esbuild-sass-modules-plugin

A sass module loader plugin for esbuild.

This plugin allows .scss and .sass files to be imported as modules in javascript files.

Warning: this module does not work with SASS 1.63.0 because of https://github.com/sass/dart-sass/issues/1995

The issue has been fixed as of SASS 1.63.4

Note: this package is a module.

Inline resolver

import style from 'inline:source.scss';

// contains the compiled css text
console.log(style);

File resolver

import style from 'file:source.scss';

// contains the text path to be fetched
fetch(style)
	.then(css => console.log(css));

Just set the postcss.use to true to enable PostCSS and set postcss.plugins to an array of plugins.
