What is this?

This package checks the style of MDX JSX attribute value markers.

When should I use this?

You can use this package to check that the style of MDX JSX attribute value markers is consistent.

Presets

This plugin is not included in presets maintained here.

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install remark-lint-mdx-jsx-quote-style

In Deno with esm.sh:

import remarkLintMdxJsxQuoteStyle from 'https://esm.sh/remark-lint-mdx-jsx-quote-style@1'

In browsers with esm.sh:

<script type="module">
  import remarkLintMdxJsxQuoteStyle from 'https://esm.sh/remark-lint-mdx-jsx-quote-style@1?bundle'
</script>

Use

On the API:

import remarkLint from 'remark-lint'
import remarkLintMdxJsxQuoteStyle from 'remark-lint-mdx-jsx-quote-style'
import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import {read} from 'to-vfile'
import {unified} from 'unified'
import {reporter} from 'vfile-reporter'

const file = await read('example.md')

await unified()
  .use(remarkParse)
  .use(remarkLint)
  .use(remarkLintMdxJsxQuoteStyle)
  .use(remarkStringify)
  .process(file)

console.error(reporter(file))

On the CLI:

remark --frail --use remark-lint --use remark-lint-mdx-jsx-quote-style .

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

 …
 "remarkConfig": {
   "plugins": [
     …
     "remark-lint",
+    "remark-lint-mdx-jsx-quote-style",
     …
   ]
 }
 …

API

This package exports no identifiers. It exports the TypeScript types Options and Style. The default export is remarkLintMdxJsxQuoteStyle.

unified().use(remarkLintMdxJsxQuoteStyle[, options])

Warn when MDX JSX attribute value markers violate a given style.

Parameters

• options (Options, default: 'consistent') — preferred style or whether to detect the first style and warn for further differences

Returns

Transform (Transformer from unified).

Options

Configuration (TypeScript type).

Type

type Options = Style | 'consistent'

Style

Style (TypeScript type).

Type

type Style = '"' | '\''

Recommendation

In HTML, attributes are commonly written with double quotes. It’s recommended to go with that. To configure this rule with '"'.

Fix

remark-mdx formats titles with double quotes by default. Pass quote: "'" to use single quotes.

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-mdx-jsx-quote-style@1, compatible with Node.js 16.
