library4.0.1jsnpmunverified

remark-lint rule to warn on empty URLs in links, images, and definitions. Version 4.0.1 is the current stable release, compatible with unified ecosystem and Node.js 16+. ESM-only since v3. Differentiates from generic linting by providing focused, low-overhead checks for empty URLs in Markdown, with no configuration options needed.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

remarkLintNoEmptyUrl

✓ import remarkLintNoEmptyUrl from 'remark-lint-no-empty-url'

✗ const remarkLintNoEmptyUrl = require('remark-lint-no-empty-url')

Package is ESM-only since v3. CommonJS require will fail.

remarkLint

✓ import remarkLint from 'remark-lint'

✗ const remarkLint = require('remark-lint')

remark-lint must be imported alongside this rule. Also ESM-only.

remarkParse

✓ import remarkParse from 'remark-parse'

Required for parsing Markdown before linting.

Demonstrates setting up the remark lint pipeline with the no-empty-url rule, parsing Markdown and reporting warnings.

import remarkLint from 'remark-lint' import remarkLintNoEmptyUrl from 'remark-lint-no-empty-url' 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(remarkLintNoEmptyUrl) .use(remarkStringify) .process(file) console.error(reporter(file))

Debug

Known issues

breakingv3 dropped CommonJS support; package is ESM-only.

fix

Use ES module import syntax or switch to v2 if CJS required.

affects: >=3.0.0

deprecatedv2.x is deprecated and no longer maintained.

fix

Upgrade to v4.0.1 and use ESM import.

affects: <3.0.0

gotchaThis rule must be used after remark-parse and remark-stringify in the pipeline, otherwise it may not detect empty URLs.

fix

Ensure pipeline order: .use(remarkParse).use(remarkLint).use(remarkLintNoEmptyUrl).use(remarkStringify)

affects: >=1.0.0

gotchaThe rule reports empty URLs even when the empty URL is intended (e.g., for placeholder).

fix

If intentional, use a different rule or disable this one.

affects: >=1.0.0

Errors

Error [ERR_REQUIRE_ESM]: require() of ES Module not supported.

Using require() on an ESM-only package.

fix

Change to dynamic import or use ESM syntax.

TypeError: Cannot read properties of null (reading 'url')

Missing unified plugins in pipeline.

fix

Add .use(remarkParse) and .use(remarkStringify) before processing.
