## 📜 About
|
|
|
|
**markdownlint-rule-relative-links** is a [markdownlint](https://github.com/DavidAnson/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](https://github.com/DavidAnson/markdownlint).
|
|
|
|
### Example
|
|
|
|
File structure:
|
|
|
|
```txt
|
|
├── abc.txt
|
|
└── awesome.md
|
|
```
|
|
|
|
With `awesome.md` content:
|
|
|
|
```md
|
|
[abc](./abc.txt)
|
|
|
|
[Invalid link](./invalid.txt)
|
|
```
|
|
|
|
Running [markdownlint-cli2](https://github.com/DavidAnson/markdownlint-cli2) with `markdownlint-rule-relative-links` will output:
|
|
|
|
```sh
|
|
awesome.md:3 relative-links Relative links should be valid ["./invalid.txt" should exist in the file system]
|
|
```
|
|
|
|
### Additional features
|
|
|
|
- Support images (e.g: ``).
|
|
- Support links fragments similar to the [built-in `markdownlint` rule - MD051](https://github.com/DavidAnson/markdownlint/blob/main/doc/md051.md) (e.g: `[Link](./awesome.md#heading)`).
|
|
- Ignore external links and absolute paths as it only checks relative links (e.g: `https://example.com/` or `/absolute/path.png`).
|
|
|
|
### Limitations
|
|
|
|
- Only images and links defined using markdown syntax are validated, html syntax is ignored (e.g: `<a href="./link.txt" />` or `<img src="./image.png" />`).
|
|
|
|
Contributions are welcome to improve the rule, and to alleviate these limitations. See [CONTRIBUTING.md](./CONTRIBUTING.md) for more information.

## Prerequisites
|
|
|
|
[Node.js](https://nodejs.org/) >= 16.0.0
|
|
|
|
## Installation
|
|
|
|
```sh
|
|
npm install --save-dev markdownlint-rule-relative-links
|
|
```
|
|
|
|
## Configuration
|
|
|
|
There are various ways [markdownlint](https://github.com/DavidAnson/markdownlint) can be configured using objects, config files etc. For more information on configuration refer to [options.config](https://github.com/DavidAnson/markdownlint#optionsconfig).
|
|
|
|
We recommend configuring [markdownlint-cli2](https://github.com/DavidAnson/markdownlint-cli2) over [markdownlint-cli](https://github.com/igorshubovych/markdownlint-cli) for compatibility with the [vscode-markdownlint](https://github.com/DavidAnson/vscode-markdownlint) extension.
