    linkTool: {

      config: {

  },

  ...

Output data

This Tool returns data with following format

Field	Type	Description
link	string	Pasted link's url

{
    "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"
            }
        }
    }
}

Backend response format

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.

Providing custom fetch method

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.
