HTML XBlock

A new HTML XBlock that is designed with security and embedding in mind.

Introduction

This XBlock provides a newer alternative to the existing HTML XModule in edX platform as it presents a number of problems when trying to embed it in another site (in particular, it often hosts content that depends on JS globals like jQuery being present, and it allows users to include arbitrary JavaScript).

Installation

You may install XBlock-html using its setup.py, or if you prefer to use pip, run:

pip install https://github.com/open-craft/xblock-html

You may specify the -e flag if you intend to develop on the repo.

Note that as of version 1.0.0, Python 2.7 is no longer supported. The current minimum Python version is 3.8.

To enable this block, add "html5" and "excluded_html5" to the course's advanced module list. The options Text and Exclusion will appear in the advanced components.

Configuration

The tables added to the content in the WYSIWYG editor can be styled according the theming requirements of the deployment by adding custom CSS classes to them. Add the following to your XBLOCK_SETTINGS part of the CMS/Studio confguration:

XBLOCK_SETTINGS = {
    "html5": {
        "table_custom_classes": ["your-list", "of-css", "classes"]
    }
}

These classes will be available in the "General" tab of "Table Properties" dialog, under "Classes".

Development

If you're willing to develop on this repo, you need to be familiar with different technologies and the repos' dependencies. However, to make things easier to setup and to manage, there're bunch of make commands that you can use to do things faster.
