unified().use(remarkLintNoLiteralUrls)

Warn when GFM autolink literals are used.

Parameters

There are no options.

Returns

Transform (Transformer from unifiedgithub-unified-transformer).

Recommendation

GFM autolink literals (just a raw URL) are a feature enabled by GFM. They don’t work everywhere. So, it’s recommended to instead use regular autolinks (<https://url>) or full links ([text](url)).

Fix

remark-stringifygithub-remark-stringify never generates GFM autolink literals. It always generates regular autolinks or full links.
