Gulpfile to compile scss to css and copy result to clipboard. Handy!!

gulpfile.js

'use strict'

// npm i gulp node-sass gulp-sass clipboardy through2

var gulp = require('gulp')
var sass = require('gulp-sass')
var clipboardy = require('clipboardy')
var through2 = require('through2')

sass.compiler = require('node-sass')

function compileScss() {
  var opts = {
    outputStyle: 'expanded'
  }
  return gulp.src('./*.scss')
    .pipe(sass(opts).on('error', sass.logError))
    .pipe(through2.obj(function (file, enc, callback) {

      if (file.isNull()) {
        this.push(file)
        return callback()
      }

      if (file.isStream()) {
        return callback(new Error('Streaming not supported'))
      }

      if (file.isBuffer()) {
        clipboardy.writeSync(String(file.contents))
        this.push(file)
      }

      return callback(null, file)
    }))
    .pipe(gulp.dest('.'))
}

gulp.task('sass', compileScss)

gulp.task('sass:watch', function () {
  gulp.watch('./*.scss', compileScss)
})

gulp.task('default', gulp.series('sass', 'sass:watch'))
