Example 1 (gulp 3.9.1):

`javascript
const gulp = require('gulp');
const { cache, compare, uncache, remove } = require('gulp-cache-uncache');
const uglify = require('gulp-uglify');
const concat = require('gulp-concat');

gulp.task('preBundle', () => {
return gulp.src('src/*')
.pipe(cache('src')); //caches all files in order
});

gulp.task('bundle', [ 'preBundle' ], () => {
return gulp.src('src/*')
.pipe(compare('src')) //compares cached files and only releases changed files
.pipe(uglify())
.pipe(uncache('src')) //releases all uglified files in order specified in cache
.pipe(concat('bundle.js'))
.pipe(gulp.dest('dist'));
});

gulp.task('watch' ,() => {
const watcher = gulp.watch('src/*', ['bundle']);
watcher.on('change', function (event) {
if (event.type === 'deleted') {
remove('src', event.path); //remove file from cache
}
});
});

gulp.task('default', ['watch']);
`

Example 2 (gulp 4.0.0):

`javascript
const gulp = require('gulp');
const { cache, compare, uncache, remove } = require('gulp-cache-uncache');
const uglify = require('gulp-uglify');
const concat = require('gulp-concat');

gulp.task('preBundle', () => {
return gulp.src('src/*')
.pipe(cache('src')); //caches all files in order
});

gulp.task('bundle', () => {
return gulp.src('src/*')
.pipe(compare('src')) //compares cached files and only releases changed files
.pipe(uglify())
.pipe(uncache('src')) //releases all uglified files in order specified in cache
.pipe(concat('bundle.js'))
.pipe(gulp.dest('dist'));
});

gulp.task('watch', () => {
const watcher = gulp.watch('src/*', gulp.series('preBundle', 'bundle'));
watcher.on('unlink', function (path) {
remove('src', path); //remove file from cache
});
