gulp-clean

A gulp plugin for removing files and folders.

Deprecated use gulp-rimraf instead!

gulp-clean

Removes files and folders.

Install with npm.

npm install --save-dev gulp-clean
var gulp = require('gulp');
var clean = require('gulp-clean');
 
gulp.task('default', function () {
    return gulp.src('app/tmp', {read: false})
        .pipe(clean());
});

Option read:false prevents gulp from reading the contents of the file and makes this task a lot faster. If you need the file and its contents after cleaning in the same stream, do not set the read option to false.

var gulp = require('gulp');
var clean = require('gulp-clean');
 
gulp.task('default', function () {
    return gulp.src('app/tmp/index.js')
        .pipe(clean({force: true}))
        .pipe(gulp.dest('dist'));
});

Clean as a dependency:

var gulp = require('gulp');
var clean = require('gulp-clean');
 
gulp.task('clean-scripts', function () {
  return gulp.src('app/tmp/*.js', {read: false})
    .pipe(clean());
});
 
gulp.task('scripts', ['clean-scripts'], function () {
  gulp.src('app/scripts/*.js')
    .pipe(gulp.dest('app/tmp'));
});
 
gulp.task('default', ['scripts']);

Make sure to return the stream so that gulp knows the clean task is asynchronous and waits for it to terminate before starting the dependent one.
