Install

This package is ESM only: Node 12+ is needed to use it and it must be importeded instead of requiredd.

npm:

npm install remark-lint-final-newline

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

Use

You probably want to use it on the CLI through a config file:

 …
 "remarkConfig": {
   "plugins": [
     …
     "lint",
+    "lint-final-newline",
     …
   ]
 }
 …

Or use it on the CLI directly

remark -u lint -u lint-final-newline readme.md

Or use this on the API:

 import {remark} from 'remark'
 import {reporter} from 'vfile-reporter'
 import remarkLint from 'remark-lint'
 import remarkLintFinalNewline from 'remark-lint-final-newline'

 remark()
   .use(remarkLint)
+  .use(remarkLintFinalNewline)
   .process('_Emphasis_ and **importance**')
   .then((file) => {
     console.error(reporter(file))
   })
