Parse :emoji: as emoji either unicode characters or images. You have to provide your own emojis. The example uses the list of emojis provided by @octokit/rest but you can also just create your own list from any source.

The emojis option is required.

Usage

import {marked} from "marked";
import {markedEmoji} from "marked-emoji";

const octokit = new Octokit();
// Get all the emojis available to use on GitHub.
const res = await octokit.rest.emojis.get();
/*
 * {
 *   ...
 *   "heart": "https://...",
 *   ...
 *   "tada": "https://...",
 *   ...
 * }
 */
const emojis = res.data;
const options = {
	emojis,
	renderer: (token) => `<img alt="${token.name}" src="${token.emoji}" class="marked-emoji-img">`
};
marked.use(markedEmoji(options));
marked.parse("I :heart: marked! :tada:");
// <p>I <img alt="heart" src="https://..." class="marked-emoji-img"> marked! <img alt="tada" src="https://..." class="marked-emoji-img"></p>
// I ❤️ marked! 🎉
