How to set up sourcemap generation in VSCode?

Question

gulp.js

Good day!
I decided to master sass, installed VS Code, nodejs 7 on Win10. I set up css auto-generation using gulp using this
guide. I understand it is necessary to register something in gulpfile.js?
Advise what to do and where to read about setting up tasks for Gulp.

we somehow made it

var babel = require('babel-core/register');
var babelify = require('babelify');

gulp.task('app_js_min', function(done) {
    var b = browserify({
        extensions: ['.js', '.jsx'],
        debug: true,
    });

    return b.transform(babelify)
     .plugin('minifyify', {
         map: 'app.map',
         uglify: {
             mangle: false,
             compress: {
                 drop_debugger: false,
                 drop_console: false,
             }
         },
         output: DIST_DIR + '/js/app.map'
     })
     .add(SRC_DIR + "/index.js")
     .bundle()
     .pipe(source('app.min.js'))
     .pipe(gulp.dest(DIST_DIR + "/js"));
});
