remark-lint-strong-marker

4.0.1 verified Fri May 01 auth: no javascript

A remark-lint rule that warns when strong (bold) markers are inconsistent. Version 4.0.1 is the latest stable release (ESM-only, Node.js 16+). It enforces a consistent style for strong markers (`*` or `_`) or auto-detects the first style used. Part of the remark-lint ecosystem with presets like `remark-preset-lint-consistent`. Ships TypeScript declarations. Has no runtime dependencies beyond remark-lint.

Common errors

error Cannot find module 'remark-lint-strong-marker' ↓

cause Package not installed or not in node_modules.

fix

Run: npm install remark-lint-strong-marker

error SyntaxError: Unexpected token 'export' ↓

cause Using CommonJS require() in an ESM-only package.

fix

Switch to ESM imports as shown above, or use dynamic import.

error TypeError: Cannot read properties of undefined (reading 'type') ↓

cause The plugin is used before the remark parser.

fix

Add .use(remarkParse) before .use(remarkLintStrongMarker).

error Expected a `Marker` but got `'**'` ↓

cause Invalid option value: strong markers must be single `*` or `_`, not `**`.

fix

Use '*' or '_' as the option value.

Warnings

breaking Package is ESM-only; using require() throws an error. ↓

fix Use import syntax (ESM). For CommonJS projects, use dynamic import: const m = await import('remark-lint-strong-marker')

gotcha The plugin must be used after remarkParse and before remarkStringify. Incorrect order causes no linting. ↓

fix Ensure .use(remarkParse).use(remarkLint).use(remarkLintStrongMarker).use(remarkStringify) order

deprecated No deprecated versions known; rule remains stable.

gotcha If no defaults are set, the rule uses 'consistent' mode: warns when a strong marker differs from the first used style. ↓

fix Specify options explicitly: .use(remarkLintStrongMarker, '*') or .use(remarkLintStrongMarker, '_')

gotcha The rule only checks strong markers, not emphasis or other formatting. ↓

fix Use separate remark-lint rules for emphasis markers (e.g., remark-lint-emphasis-marker).

breaking Node.js version requirement changed from 12 to 16. ↓

fix Upgrade Node.js to version 16 or later.

Install

npm install remark-lint-strong-marker

yarn add remark-lint-strong-marker

pnpm add remark-lint-strong-marker

Imports

remarkLintStrongMarker

wrong

const remarkLintStrongMarker = require('remark-lint-strong-marker')

correct

import remarkLintStrongMarker from 'remark-lint-strong-marker'

ESM-only since v3; CommonJS require is not supported.

Marker
```
import type { Marker } from 'remark-lint-strong-marker'
```
TypeScript type export for marker style ('*' | '_'). Use type import to avoid runtime overhead.
Options
```
import type { Options } from 'remark-lint-strong-marker'
```
TypeScript type export for plugin options (Marker or 'consistent').

Quickstart

Checks strong markers in example.md, reporting any inconsistent use.

import remarkLint from 'remark-lint'
import remarkLintStrongMarker from 'remark-lint-strong-marker'
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(remarkLintStrongMarker)
  .use(remarkStringify)
  .process(file)

console.error(reporter(file))
