markdown/no-bare-urls

GitHub Flavored Markdown turns a URL or an email address in plain text into a link. CommonMark doesn't, so the same document has a link on GitHub and plain text elsewhere. < and > around the URL make it a link everywhere.

Only markdown/gfm finds links in plain text, so the rule reports nothing in markdown/commonmark.

--fix puts < and > around the URL.

Configure#

Off by default. It needs an ESLint config that says which files are in the language:

import markdown from "@eslint/markdown";

export default [
  {
    files: ["**/*.md"],
    plugins: { markdown },
    language: "markdown/gfm",
    rules: { "markdown/no-bare-urls": "error" },
  },
];

It also works with markdown/commonmark.

Examples#

See https://bun.com/docs or write to hello@example.com.

See <https://bun.com/docs>, the [docs](https://bun.com/docs), or `https://bun.com/docs`.

A URL between an opening and a closing HTML tag is left alone:

See <a href="https://bun.com/docs">https://bun.com/docs</a>.
