Integration and Setup

These options control how Editor42 initializes, which element it targets, which plugins it loads, and how it communicates back to your application.

Options

Option	Type	Default	Description
selector	string	—	CSS selector matching the element(s) to replace with an editor instance.
target	HTMLElement	—	Direct DOM element reference to convert into an editor. Use instead of selector when you already have a reference.
inline	boolean	false	Enable inline editing mode. The editor appears inside the target element itself rather than in an iframe.
base_url	string	—	Base URL for loading Editor42 resource files (skins, themes, plugins).
suffix	string	—	Suffix appended to script filenames, e.g. '.min' for minified builds.
cache_suffix	string	—	Query string appended to resource URLs for cache busting, e.g. '?v=1.0'.
setup	function	—	Callback invoked before the editor is fully initialized. Receives the editor instance as its argument. Use this to bind events or configure the editor early.
init_instance_callback	function	—	Callback invoked after the editor has fully initialized. Receives the editor instance.
plugins	string[]	[]	List of plugins to load. Each entry is a plugin alias name — see the available plugins.
external_plugins	object	—	Map of plugin names to their script URLs, for loading plugins hosted outside the Editor42 package.
model	string	'dom'	Content model the editor uses internally.
referrer_policy	string	''	Referrer policy applied to resource requests made by the editor.
language	string	'en'	Language code for the editor UI.
language_url	string	''	URL to a custom language pack file.
language_load	boolean	true	Whether the editor should load its language pack automatically.
readonly	boolean	false	Start the editor in read-only mode. Content is displayed but not editable.
editable_root	boolean	true	Whether the root element of the editor body is editable. Set to false to make only specific child elements editable.
auto_focus	string/true	—	Automatically focus an editor on page load. Pass true to focus the last initialized editor, or an editor id string to focus a specific one.
id	string	—	Explicit id for the editor instance. If omitted, the id of the target element is used.
api_key	string	—	API key field. Not used in Editor42.
deprecation_warnings	boolean	true	Log deprecation warnings to the browser console when deprecated options are used.

Example

editor42.init({
  selector: 'textarea#content',
  plugins: ['lists', 'link', 'image', 'code'],
  language: 'de',
  setup: (editor) => {
    editor.on('init', () => {
      console.log('Editor ready');
    });
  },
  init_instance_callback: (editor) => {
    console.log('Fully initialized:', editor.id);
  }
});
