Understanding Block Plugins →
I loved reading this write-up from Rich Tabor about the what and why of Block Plugins. For those new to this whole thing, I’ll pull his opening summary:
What are Block Plugins?
If you’ve built blocks before, you may be asking what’s the big deal about block plugins. For the most part, you can think of block plugins as one block, registered and compiled completely in JavaScript, that serves a singular function. These plugins exist solely to distribute a block — and nothing more… and these plugins are meant to be included within the Block Directory.
He goes in to way more besides that—how to make them, what they look like, and how make sure yours works—so be sure to give the whole thing a look.
