Hyperlink

The Link extension adds support for <a> tags to the editor. The extension is headless, there is no actual UI to add, modify or delete links. The usage example below uses the native JavaScript prompt to show you how that could work.

In a real world application, you would probably add a more sophisticated user interface.

Installation

npm install @docs.plus/extension-hyperlink

Settings

protocols

Additional custom protocols you would like to be recognized as links.

Default: []

Hyperlink.configure({
  protocols: ['ftp', 'mailto'],
})

By default, linkify adds // to the end of a protocol however this behavior can be changed by passing optionalSlashes option

Hyperlink.configure({
  protocols: [
    {
      scheme: 'tel',
      optionalSlashes: true
    }
  ]
})

autolink

If enabled, it adds links as you type.

Default: true

Hyperlink.configure({
  autolink: false,
})

openOnClick

If enabled, links will be opened on click.

Default: true

Hyperlink.configure({
  openOnClick: false,
})

linkOnPaste

Adds a link to the current selection if the pasted content only contains an url.

Default: true

Hyperlink.configure({
  linkOnPaste: false,
})

HTMLAttributes

Custom HTML attributes that should be added to the rendered HTML tag.

Hyperlink.configure({
  HTMLAttributes: {
    class: 'my-custom-class',
  },
})

Modals

The Modals configuration option lets you incorporate an interactive user interface similar to Google Docs for setting and previewing hyperlinks. This provides users with a more intuitive and interactive experience;

• Dive into the code
• Demo

The `previewHyperlinkModal` function

function previewHyperlinkModal(options) {
  const href = options.link.href;

  const hyperlinkModal = document.createElement("div");
  const removeButton = document.createElement("button");
  const copyButton = document.createElement("button");

  const newBubble = document.createElement("div");
  newBubble.classList.add("hyperlink-preview-modal__metadata");

  const hrefTitle = document.createElement("a");
  hrefTitle.setAttribute("target", "_blank");
  hrefTitle.setAttribute("rel", "noreferrer");
  hrefTitle.setAttribute("href", href);
  hrefTitle.innerText = href;

  newBubble.append(hrefTitle);

  hyperlinkModal.classList.add("hyperlink-preview-modal");

  removeButton.classList.add("hyperlink-preview-modal__remove-button");
  removeButton.innerHTML = "remove";

  copyButton.classList.add("hyperlink-preview-modal__copy-button");
  copyButton.innerHTML = "copy";

  removeButton.addEventListener("click", () => {
    options.tippy.hide();
    return options.editor.chain().focus().unsetHyperlink().run();
  });

  copyButton.addEventListener("click", () => {
    options.tippy.hide();
    navigator.clipboard.writeText(href);
  });

  hyperlinkModal.append(newBubble, copyButton, removeButton);

  return hyperlinkModal;
}

The `setHyperlinkModal` function

import { Editor } from "@tiptap/core";
import { find } from "linkifyjs";

let tooltip = undefined;

function setHyperlinkModal(options) {
  // Create the tooltip instance
  if (!tooltip) tooltip = new options.Tooltip(options);

  // Initialize the tooltip
  let { tippyModal } = tooltip.init();

  const hyperlinkModal = document.createElement("div");
  const buttonsWrapper = document.createElement("div");
  const inputsWrapper = document.createElement("div");

  hyperlinkModal.classList.add("hyperlink-set-modal");

  buttonsWrapper.classList.add("hyperlink-set-modal__buttons-wrapper");
  inputsWrapper.classList.add("hyperlink-set-modal__inputs-wrapper");

  // create a form that contain url input and a button for submit
  const form = document.createElement("form");
  const input = document.createElement("input");
  const button = document.createElement("button");

  input.setAttribute("type", "text");
  input.setAttribute("placeholder", "https://example.com");
  button.setAttribute("type", "submit");
  button.innerText = "Submit";

  inputsWrapper.append(input);
  buttonsWrapper.append(button);
  form.append(inputsWrapper, buttonsWrapper);

  hyperlinkModal.append(form);

  tippyModal.innerHTML = "";
  tippyModal.append(hyperlinkModal);
  tooltip.update(options.editor.view, {
    arrow: options.roundArrow,
  });

  // make sure
  setTimeout(() => input.focus();, 100);

  // event listenr for submit button
  form.addEventListener("submit", (event) => {
    event.preventDefault();
    const url = input.value;

    if (!url) return;

    const sanitizeURL = find(url)
      .filter((link) => link.isLink)
      .filter((link) => {
        if (options.validate) {
          return options.validate(link.value);
        }
        return true;
      })
      .at(0);

    if (!sanitizeURL?.href) return;

    tooltip?.hide();

    return options.editor
      .chain()
      .setMark(options.extentionName, { href: sanitizeURL.href })
      .setMeta("preventautohyperlink", true)
      .run();
  });
}

import {
  Hyperlink,
  previewHyperlinkModal,
  setHyperlinkModal
} from "@docs.plus/extension-hyperlink";

Hyperlink.configure({
  modals: {
    previewHyperlink: (data) => {
      return previewHyperlinkModal(data);
    },
    setHyperlink: (data) => {
      return setHyperlinkModal(data);

  },
})

Note: The previewHyperlinkModal and setHyperlinkModal modals are prebuilt modal boxes. You can use them or create your own modal boxes. To learn how to create your own modal boxes, please check the source code

Removing and overriding existing html attributes

You can add rel: null to HTMLAttributes to remove the default rel="noopener noreferrer nofollow". You can also override the default by using rel: "your-value".

This can also be used to change the target from the default value of _blank.

Hyperlink.configure({
  HTMLAttributes: {
    // Change rel to different value
    // Allow search engines to follow links(remove nofollow)
    rel: 'noopener noreferrer',
    // Remove target entirely so links open in current tab
    target: null,
  },
})

validate

A function that validates every autolinked link. If it exists, it will be called with the link href as argument. If it returns false, the link will be removed.

Can be used to set rules for example excluding or including certain domains, tlds, etc.

// only autolink urls with a protocol
Hyperlink.configure({
  validate: href => /^https?:\/\//.test(href),
})

Commands

editHyperLinkText(), editHyperLinkHref(), editHyperlink()

These commands allow you to edit the text and href value of a hyperlink.

this.editor.commands.editHyperLinkText('New Text');
this.editor.commands.editHyperLinkHref('https://new-url.com');
this.editor.commands.editHyperlink({
  newText: 'New Text',
  newURL: 'https://new-url.com'
});

setHyperlink()

Links the selected text.

this.editor.commands.setHyperlink({
  href: '<https://example.com>'
});

this.editor.commands.setHyperlink({
  href: '<https://example.com>',
  target: '_blank'
});

this.editor.commands.unsetHyperlink();

unsetHyperlink()

Removes a Hyperlink.

this.editor.commands.unsetHyperlink();

Keyboard shortcuts

Doesn’t have a keyboard shortcut This extension doesn’t bind a specific keyboard shortcut. You would probably open your custom UI on Mod-k though.

Get the current value

Did you know that you can use getAttributes to find out which attributes, for example which href, is currently set? Don’t confuse it with a command (which changes the state), it’s just a method. Here is how that could look like:

this.editor.getAttributes('link').href
