Proper Error Handling in gulp.js

.js

var gulp = require('gulp');
var plumber = require('gulp-plumber');
var gutil = require('gulp-util');
 
var gulp_src = gulp.src;
gulp.src = function() {
  return gulp_src.apply(gulp, arguments)
    .pipe(plumber(function(error) {
      // Output an error message
      gutil.log(gutil.colors.red('Error (' + error.plugin + '): ' + error.message));
      // emit the end event, to properly end the task
      this.emit('end');
    })
  );
};
