// Methods
editor.exec(cmd: string, value?: string) // execute document command (document.executeCommand(cmd, false, value))
editor.getHtml(sanitize?: boolean) // returns html string from editor. if passed true as argument, html will be sanitized before return
editor.getText() // returns text string from editor
editor.setHtml(html: string, sanitize?: boolean) // sets html for editor. if second argument is true, html will be sanitized
editor.saveRange() // saves current editor cursor position or user selection
editor.restoreRange() // restores cursor position or user selection
// saveRange and restoreRange are useful when making custom actions
// that demands that focus is shifted from editor to, for example, modal window.
  • For list of available exec command visit
    // Events
    editor.$on('change', (event) => console.log(event)) // on every keyup event
    editor.$on('blur', (event) => console.log(event)) // on editor blur event
    // Props
    editor.refs. // references to editor, raw (textarea), modal and colorPicker HTMLElements



prop lists predefined actions (and/or adds new actions) to be shown in the toolbar. If the prop is not set, all
defined and exported in actions.js are made available, in the order in which they are defined. To limit or change the order of predefined actions shown, set it by passing an array of names of actions defined, eg.:
actions={["b", "i", "u", "h2", "ul", "left", "center", "justify", "forecolor"]}
The editor looks up to see if name is already defined, and adds it to the toolbar if it is.

You can add a custom action by inserting it in the array, like how "copy" is defined in example above. Take a look at

for more examples.

Usage in Svelte

It is easier to import and work directly from the source if you are using Svelte. You can handle

events via

{@html html} html = evt.detail}

To limit or define the tools shown in the toolbar, pass in an


To easily get the editor content DOM element, pass an

prop, eg.

This is useful if you want to listen to resize of the editor and respond accordingly.

To do so, first enable resize on the editor:

.cl-content {
  resize: both;

Now observe the resize:

Run demo

git clone cl-editor
cd cl-editor
npm i
npm run dev
