This rule is included in the following presets:

Preset	Setting

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install remark-lint-hard-break-spaces

In Deno with esm.sh:

Use

On the API:

import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'
import {remark} from 'remark'
import remarkLint from 'remark-lint'
import remarkLintHardBreakSpaces from 'remark-lint-hard-break-spaces'

main()

async function main() {
  const file = await remark()

On the CLI in a config file (here a package.json):

 …
 "remarkConfig": {
   "plugins": [
     …
     "remark-lint",
+    "remark-lint-hard-break-spaces",
     …
   ]
 }
 …

API

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

unified().use(remarkLintHardBreakSpaces[, 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

Less than two spaces do not create a hard breaks and more than two spaces have no effect. Due to this, it’s recommended to turn this rule on.
