CodeMirror

Enable real-time co-editing for CodeMirror 5

Overview

Add the Codox JavaScript library and css files:

<script src="https://cdn1.codox.io/lib/2.x/api/wave.client.js" type="text/javascript"></script>

<link href="https://cdn1.codox.io/lib/2.x/css/wave.client.css" rel="stylesheet">

JavaScript code

Add the following JavaScript block to your application to enable real-time co-editing for CodeMirror. Replace the apiKey field with your own, which you can get here.

const editor = CodeMirror.fromTextArea(document.getElementById('editor'), {});

let codox = new Codox();
//Codox configuration

let config = {
    "docId"  : "mydoc",
    "app"    : "codemirror",
    "editor" : editor, 
    "apiKey" : "",
    "user"   : {"name" : "Steve"}
};

//Start!
codox.start(config);

The co-editing session will start inside the CodeMirror editor instance specified in the editorattribute.

Before invoking codox.init() the CodeMirror editor should be fully initialized. In the example code, we ensure that CodeMirror is initialized first by adding an initialized event hook to CodeMirror constructor.

The values for docIdandusername should come from your document management service. Codox expects docIdto be globally unique across your service.

Multiple Instances

Every co-editing session should have its distinct codox object. That means if you are running multiple instances of CodeMirror editor on the same page or with in the same application, there should be multiple instances of codox, one for each CodeMirror editor instance or document fragment (note: each document fragment should be uniquely identifiable).

Parameters

The config parameter is a JSON object with the following key-value pairs:

Summary

Key		Value
app	(required)	string
docId	(required)	string
user	(required)	object
apiKey	(required)	string
