hexo-broken-links-checker Publish on NPM

hexo-broken-links-checker is a plugin for Hexo static site generator that checks broken links.

  • Scans all links in the post's content and frontmatter part.
  • Able to use either HTTP HEAD or GET methods. It can use the HTTP HEAD method to speed up the link checking. If it fails, it will double-check with HTTP GET request.
  • No more broken links on your website. Be sure that all links on your website are up to date.

How it works

  1. Once the plugin installed, new check-links console command appears.
  2. Running npx hexo check-links the plugin will scan all posts (and their frontmatter, if it is configured) and extract all links to external resources (http:// and https:// only).
  3. Finally, the plugin checks all links one by one via HTTP GET/HEAD method. If any links are broken (HTTP status code is other than 2xx), the console error will appear 👌.

Requirements

  • Hexo: 5.x
  • Node 12+

Usage

  1. Install the plugin using npm:
$ npm install hexo-broken-links-checker --save-dev
  1. Run the plugin:
$ npx hexo check-links
  1. Drink some tea ☕️ while the plugin checking the links.
  2. See if there are any broken links on the website.

It's useful to integrate the command running into CI workflow.

    head: true
    frontmatter:

    exclude:

        - https://website2.com/page2.html
    timeout: 1000
    useragent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 11_0_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36'
