Use Cache

const gulp         = require('gulp');
const rollupStream = require('rollup-vinyl-stream');
let   cache;

gulp.task('rollup', () =>
  rollupStream({
    config: './rollup.config.js',
    cache,
  })
  .on('bundle', (bundle) => cache = bundle)
  .pipe(gulp.dest('./dist'))
);

const gulp         = require('gulp');
const rollupStream = require('rollup-vinyl-stream');
let   options      = {config: './rollup.config.js'};

gulp.task('rollup', () =>
  rollupStream(options)
  .on('config', (config) => options = config)
  .on('bundle', (bundle) => options.cache = bundle)
  .pipe(gulp.dest('./dist'))
