Gulp 3 to Gulp 4
Towards the end of 2018, Gulp 4 became the default version installed with
npm install gulp
which is incompatible with Gulp 3 Gulpfiles.
This repository is a reference for converting a minimal Gulp 3 Gulpfile to a Gulp 4 Gulpfile. It is accompanied by a blog post.
The environment I wrote this used Node.js v10 & npm v6.
