2.1 JavaScript API

mdLinks(path, options)

Arguments

• path: Absolute or relative path to the file or directory. If the path passed is relative, it should resolve to relative to the directory where node is invoked from - current working directory).
• options: An object with only the following properties:
  • validar: Boolean that determines if you want to validate the links found.
  • stats: Boolean that determines if you want to get an output with general statistical information.

Return value

The function must return a promise (Promise) that resolves to an array (Array) of objects (Object), where each object represents a link and contains the properties.

2.2 CLI (Command Line Interface)

To run md-links in the terminal, it must be entered as follows: md-links <path-to-file> [options]

The Md-links program receives a relative or absolute path as the first parameter and allows the following options as input.

• Validate
• Stats

When entering only the path, the result will be the path, the link and the link text.

For example: With validate: false:

• href: URL found.
• text: Text that appears inside the link (<a>).
• file: Path of the file where the link was found.

Options

--validate

If you enter the --validate option, the module must make an HTTP request to find out if the link works or not. If the link results in a redirect to a URL that responds ok or fail. ( Validate:true )

With validate:true :

• href: URL found.
• text: Text that appears inside the link (<a>).
• file: Path of the file where the link was found.
• status: HTTP response code.
• ok: Message fail on failure or ok on success.

For example:

$ md-links ./some/example.md --validate
./some/example.md http://algo.com/2/3/ ok 200 Link a algo
./some/example.md https://otra-cosa.net/algun-doc.html fail 404 algún doc
./some/example.md http://google.com/ ok 301 Google

--stats

If you enter the --stats option the output will be a text with basic statistics about the links.

$ md-links ./some/example.md --stats
Total: 3
Unique: 3

Also if you enter --stats and --validate you can get statistics that need the validation results. you need from the validation results.

$ md-links ./some/example.md --stats --validate
Total: 3
Unique: 3
Broken: 1
