Gulp filter. Lists all files used. Helps you to verify what your patterns catch

npm install --save-dev gulp-using

After some complex src patterns, and some added filter plugins, it helps you to list all files catched

const using = require('gulp-using')

var jsfiles = ['./src/js/**/*.js', '!./src/js/vendor/**']

gulp.task('default', function() {
  gulp.watch(jsfiles, function() {
    gulp.src(jsfiles)
      // action or filter...
      .pipe(using())
      // ...
  })
})

Output:
