Add a new Tool to the tools property of the Editor.js initial config.

  ...

  tools: {
    ...
    embed: Embed,
  },

  ...
});

Available configuration

Embed Tool supports some services by default (see the full list here). You can specify services you would like to use:

var editor = EditorJS({
  ...

  tools: {
    ...
    embed: {
      class: Embed,
      config: {
        services: {
          youtube: true,
          coub: true
        }
      }
    },
  },

  ...
});

Note that if you pass services you want to use like in the example above, others will not be enabled.

Also you can provide your own services using simple configuration.

First of all you should create a Service configuration object. It contains following fields:

Field Type Description
regex RegExp Pattern of pasted URLs. You should use regexp groups to extract resource id
embedUrl string Url of resource`s embed page. Use <%= remote_id %> to substitute resource identifier
html string HTML code of iframe with embedded content. embedUrl will be set as iframe src
height number Optional. Height of inserted iframe
width number Optional. Width of inserted iframe
id Function Optional. If your id is complex you can provide function to make the id from extraced regexp groups

Example:

{
  regex: /https?:\/\/codepen.io\/([^\/\?\&]*)\/pen\/([^\/\?\&]*)/,
  embedUrl: 'https://codepen.io/<%= remote_id %>?height=300&theme-id=0&default-tab=css,result&embed-version=2',
  html: "<iframe height='300' scrolling='no' frameborder='no' allowtransparency='true' allowfullscreen='true' style='width: 100%;'></iframe>",
  height: 300,
  width: 600,
  id: (groups) => groups.join('/embed/')
}

When you create a Service configuration object, you can provide it with Tool`s configuration:

var editor = EditorJS({
  ...

  tools: {
    ...
    embed: {
      class: Embed,
      config: {
        services: {
          youtube: true,
          coub: true,
          codepen: {
            regex: /https?:\/\/codepen.io\/([^\/\?\&]*)\/pen\/([^\/\?\&]*)/,
            embedUrl: 'https://codepen.io/<%= remote_id %>?height=300&theme-id=0&default-tab=css,result&embed-version=2',
            html: "<iframe height='300' scrolling='no' frameborder='no' allowtransparency='true' allowfullscreen='true' style='width: 100%;'></iframe>",
            height: 300,
            width: 600,
            id: (groups) => groups.join('/embed/')
          }
        }
      }
    },
  },

  ...
});

Inline Toolbar

Editor.js provides useful inline toolbar. You can allow it`s usage in the Embed Tool caption by providing inlineToolbar: true.

var editor = EditorJS({
  ...

  tools: {
    ...
    embed: {
      class: Embed,
      inlineToolbar: true
    },
  },

  ...
});
