@rubenarakelyan/rehype-custom-emoji

@rubenarakelyan/rehype-custom-emoji is a rehype plugin to replace :emoji: with custom-defined images.

Heavily inspired by remark-emoji.

Usage

rehype().use(emoji, options);

import { rehype } from "rehype";
import customEmoji from "@rubenarakelyan/rehype-custom-emoji";

const doc = "Emojis in this text will be replaced: :dog:";
const processor = rehype().use(customEmoji, {
  emoji: {
    dog: "/images/dog.png"
  }
});
const file = await processor.process(doc);

console.log(String(file));
// => Emojis in this text will be replaced: <img src="/images/dog.png" alt="dog emoji" class="custom-emoji" aria-hidden>

Remember to import the global.css stylesheet to apply some basic styling to your custom emoji. This mostly ensures that the emoji are the same size as the surrounding text so they act like real emoji.

If you are using the TailwindCSS typography extension's prose styling, you will need some extra CSS to remove the top and bottom margins it applies to all images.

Options

options.emoji

An object where the keys are the emoji shortcodes, and values are paths to the custom emoji images. For example,

{
  dog: "/images/dog.png"
}

will register the shortcode :dog:, which will be replaced with an HTML <img> tag pointing to /images/dog.png.
