SharePoint Framework (SPFx) Quick Start (Gulp toolchain for SPFx v1.21.0 and earlier)
It’s been a while since I posted, but with SPFx v1.22.0 due out in the next couple of weeks, I decided to make a final update to this article on how to get started with SPFx using the Gulp toolchain. In case you haven’t heard, v1.22.0 will no longer use Gulp as it is being replaced with Heft. The main reason for this change is that the Gulp toolchain has been very difficult to keep up-to-date, and the internal engineering teams at Microsoft switched to Heft a while back. Since they are actively maintaining Heft for their own use, we will now benefit from that work.
Expect a companion post soon on getting started with SPFx using the Heft toolchain.
