Extracts links from markdown texts and checks whether each link is alive (200 OK) or dead.

To add the module to your project, run:

npm install --save markdown-link-check

To install the command line tool globally, run:

npm install -g markdown-link-check

Given a string containing markdown formatted text and a callback, extract all of the links and check if they're alive or dead. Call the callback with (err, results)

Parameters:

• markdown string containing markdown formatted text.
• callback function which accepts (err, results).
• err an Error object when the operation cannot be completed, otherwise null.
• results an array of objects with the following properties:
• link the link provided as input
• status a string set to either alive or dead.
• statusCode the HTTP status code. Set to 0 if no HTTP status code was returned (e.g. when the server is down).
• err any connection error that occurred, otherwise null.

'use strict';

var markdownLinkCheck = require('markdown-link-check');

markdownLinkCheck('[example](http://example.com)', function (err, results) {
    if (err) {
        console.error('Error', err);
        return;
    }
    results.forEach(function (result) {
        console.log('%s is %s', result.link, result.status);
    });
});

The command line tool optionally takes 1 argument, the file name or http/https URL. If not supplied, the tool reads from standard input.
