Important Notice

Blink based browsers (Chrome and its variants) are no longer supported.

To use withExEditor, you also need to prepare a host which executes your editor. The browser interacts with the host via messages, and the editor is executed by the host. Please download the host for withExEditor from asamuzaK/withExEditorHost (GitHub).
