There were a few features missing from the core and from the community, so I decided to build some super simple plugins that help me handling my contents better.
Just add this plugin to your
from HTTP to HTTPS when your book is published online.
The plugin recognises your local environment and skips the redirect.
Just add this plugin to embed a Disqus board in every page of your 3.x GitBook.
You can configure a few settings and blacklist pages that should not use it.
This plugin lets you embed a Youtube video that is fully responsive to the page size. Works great for desktop and mobile.
If you need to embed a CodePen into your pages, this plugin does the heavy lifting for you.
