A way to get all defined blocks from the rest-API / php

[janw-me]

Currently most core blocks are defined in gutenberg/blocks/build/index.js and gutenberg/editor/build/index.js (PS I'm using the plugin from dotorg)

I want to set up some conditionals depending on what blocks are in a post. And I want a user to select which blocks are allowed. But for that I need to fill a select with the blocks.

It's doable to fill the select with JS if you wp_enqueue_script( 'wp-blocks' ); on the pages you need, but then you are loading most of gutenburg on that page just to get the blocks.
I've red the way to add new blocks

Shouldn't there be an other way to do this?
Putting this in the rest API seems like a nice way to do this.

Yes, it's been proposed that all blocks should have some amount of a server definition. Considering this as a duplicate of #2751, but the reference will prove valuable as a concrete use-case. Thanks!
