. The default export is remarkLintNoMissingBlankLines
.
unified().use(remarkLintNoMissingBlankLines[, options])

Recommendation
Blank lines are required in certain sometimes confusing cases. So it’s recommended to always use blank lines between blocks.
Fix
remark-stringify
always uses blank lines between blocks. It has a join
function to customize such behavior.

Compatibility
Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, remark-lint-no-missing-blank-lines@3
, compatible with Node.js 12.
