markdownlint-rule-relative-links

Custom rule for markdownlint to validate relative links.

📜 About

markdownlint-rule-relative-links is a markdownlint custom rule to validate relative links.

It ensures that relative links (using file: protocol) are working and exists in the file system of the project that uses markdownlint.

Example

File structure:

├── abc.txt
└── awesome.md

With awesome.md content:

[abc](./abc.txt)

[Invalid link](./invalid.txt)

Running markdownlint-cli2 with markdownlint-rule-relative-links will output:

awesome.md:3 relative-links Relative links should be valid [Link "./invalid.txt" should exist in the file system]

Prerequisites

Node.js >= 16.0.0

Installation

npm install --save-dev markdownlint-rule-relative-links

Configuration

There are various ways markdownlint can be configured using objects, config files etc. For more information on configuration refer to options.config.
