npm install markdown-it --save
yarn add markdown-it

import Markdown from "markdown-it";
import MarkdownSlack from 'slack-markdown-it';

const md = Markdown();
md.use(MarkdownSlack);

md.renderInline(`*This is me in bold*, and he is in _italic_. Don't ~strikethrough~ me!`)

const md = require('markdown-it')();
md.use(require('slack-markdown-it'));

md.renderInline(`*This is me in bold*, and he is in _italic_. Don't ~strikethrough~ me!`)
