Hexo-broken-links-checker NPM

hexo-broken-links-checker

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

Once the plugin installed, new check-links console command appears.
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).
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

Install the plugin using npm:

$ npm install hexo-broken-links-checker --save-dev

Run the plugin:

$ npx hexo check-links

Drink some tea ☕️ while the plugin checking the links.
See if there are any broken links on the website.

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