Rebuild a sass/scss file with other files that have imported this file


Useful when working on a larger project: Styles can be (re-)built incrementally on a per-need basis.

# Using yarn

Usage

You can use gulp-sass-inheritance with gulp-changed to only process the files that have changed but also recompile files that import the one that changed.
'use strict';
var gulp = require('gulp');
var sassInheritance = require('gulp-sass-inheritance');
var sass = require('gulp-sass');
var cached = require('gulp-cached');
var gulpif = require('gulp-if');
var filter = require('gulp-filter');

gulp.task('sass', function() {
  return gulp.src('src/styles/**/*.scss')

    //filter out unchanged scss files, only works when watching
    .pipe(gulpif(global.isWatching, cached('sass')))

    //find files that depend on the files that have changed
    .pipe(sassInheritance({dir: 'src/styles/'}))

    //filter out internal imports (folders and files starting with "_" )
    .pipe(filter(function (file) {
      return !/\/_/.test(file.path) || !/^_/.test(file.relative);
    }))

    //process scss files
    .pipe(sass())

    //save all the files
    .pipe(gulp.dest('dist'));
});
gulp.task('setWatch', function() {
    global.isWatching = true;
});
gulp.task('watch', ['setWatch', 'sass'], function() {
    //your watch functions...
});
