I have published on GitHub the “CodeMirror Editor Bundles,” a set of pre-compile editors that can be used out of the box. Five editors are provided, covering the most common web development coding: HTML, CSS, JavaScript, SQL, and XML.
These are targeted at developers looking for a shortcut to integrating a powerful code editor like CodeMirror into their web projects. You need to download the JavaScript file and instantiate the editor, and it is done. No dependencies.
<div id="editor"></div>
<script src="htmleditor.js"></script>
<script>
var editor = new HtmlEditor("editor");
</script>

If you need a customized editor for a particular use, then you must learn how to compile CodeMirror; this forum provides the help you need.
I want to say thank you to all the good people in this forum who helped me in my journey of learning to use CodeMirror.
