API

This package exports no identifiers. The default export is remarkLintNoLiteralUrls.

unified().use(remarkLintNoLiteralUrls[, config])

This rule supports standard configuration that all remark lint rules accept (such as false to turn it off or [1, options] to configure it).
There are no options.

Recommendation

Autolink literal URLs (just a URL) are a feature enabled by GFM. They don’t work everywhere. Due to this, it’s recommended to instead use normal autolinks (<https://url>) or links ([text](url)).

Fix

remark-stringify never creates autolink literals and always uses normal autolinks (<url>).
