I turned my Drupal Canvas Full HTML notes into a clear rollout guide and backed it with a runnable repo so teams can ship rich editing without breaking permissions.
Why I Built It
Canvas ships with a powerful editor, but Full HTML in Canvas can be risky if the configuration is sloppy. I wanted a deterministic, step-by-step guide that makes the rollout safe and auditable, plus a concrete reference implementation I can point to.
The Solution
I distilled the guide into a predictable sequence and mapped it to actual code:
props:
type: object
properties:
content:
type: string
title: Content
contentMediaType: text/html
x-formatting-context: block
The Code
I built a small module/demo that mirrors the rollout steps and schema expectations. You can clone it or browse the key files here: View Code

Why I Built It

The Solution
I distilled the guide into a predictable sequence and mapped it to actual code:
- Validate prerequisites (Drupal 11.2+, Canvas 1.0.4, Full HTML text format)
- Install Canvas and Canvas Full HTML
- Enable Gin for a consistent editing baseline
- Configure Full HTML in Canvas and clear caches
- Verify component schemas expose contentMediaType: text/html
- Confirm Canvas AI behavior and prompting patterns for safe component use

contentMediaType: text/html

What I Learned
- Canvas Full HTML supports Drupal ^10.3 and ^11, but stable Canvas targets ^11.2, so version alignment matters.
- The Gin admin theme materially improves the Canvas authoring experience.
- Canvas AI is safer when prompts emphasize placement over creation, reducing unintended component generation.
