gitbook-plugin-link-checker

This plugin checks two things:

• If links to documents within the book are not with a domain (i. e. don't start with http:// or https://)
• If links to documents are not pointing to non-existing files

You can either set the plugin to break the build or flush warnings. It works only for markdown link syntax [text](url), it doesn't work for plain HTML.

Options:

• fqdn - List of domains that the checker should check. If any of those occur in a link, it's bad.
• dieOnError - If set to true, the build will stop, otherwise the plugin will flush only warnings

To add this plugin, enter the following in the book.json file:

{
    "plugins": [ "link-checker" ],
    "pluginsConfig": {
        "link-checker": {
            "fqdn": [
              "developers.windingtree.com"
            ],
            "dieOnError": false
        }
    }
}
