remark auto link workaround to generate correct link output format

remark-auto-link.ts

import remark from 'remark';
import parse from 'remark-parse';
import { Node } from 'unist';
import visit from 'unist-util-visit';

// simple trick to parse links with []() instead of <>
const linker = () => (tree: Node) => visit(tree, 'link', node => {
  node.title = node.title || '';
});

const remarked = await remark()
  .use(parse, { gfm: true })
  .use(linker)
  .process('https://gist.github.com');

// will output [https://gist.github.com](https://gist.github.com) instead of <https://gist.github.com>
