Link Block for the Editor.js.

Allows adding link previews to your articles.

Note: this Tool requires server-side implementation for link data fetching. See backend response format for more details.

Get the package

yarn add @boundstate/editorjs-link

Include module at your application

import LinkTool from '@boundstate/editorjs-link';

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

const editor = EditorJS({
  ...

  tools: {
    ...
    linkTool: {
      class: LinkTool,
      config: {
        endpoint: 'http://localhost:8008/fetchUrl', // Your backend endpoint for url data fetching,
      }
    }
  },

  ...
});

Link Tool supports these configuration parameters:

Note that if you don't implement your custom fetch method, the endpoint parameter is required.

This Tool returns data with following format

{
    "type" : "linkTool",
    "data" : {
        "link" : "https://codex.so",
        "meta" : {
            "title" : "CodeX Team",
            "site_name" : "CodeX",
            "description" : "Club of web-development, design and marketing. We build team learning how to build full-valued projects on the world market.",
            "image" : {
                "url" : "https://codex.so/public/app/img/meta_img.png"
            }
        }
    }
}

You can implement a backend for link data fetching your own way. It is a specific and trivial task depending on your environment and stack.

Backend response should cover following format:

{
    "success" : 1,
    "link": "https://codex.so", // Optionally return a link to set the hyperlink URL
    "meta": {
        // ... any fields you want
    }
}

success — uploading status. 1 for successful, 0 for failed

link - Optional response parameter to override the URL provided

meta — link fetched data.

Currently, the plugin's design supports the 'title', 'image', and 'description' fields. They should have the following format in the response:

{
    "success" : 1,
    "meta": {
        "title" : "CodeX Team",
        "description" : "Club of web-development, design and marketing. We build team learning how to build full-valued projects on the world market.",
        "image" : {
            "url" : "https://codex.so/public/app/img/meta_img.png"
        }
    }
}

Also, it can contain any additional fields you want to store.

You have the option to provide your own custom fetch method. Use the fetcher config parameter with an object with a fetchLinkDataForUrl method that takes the url as a parameter and returns a Promise that resolves with response in the format described above.
