It’s always frustrating to follow a dead link, so I would like to avoid that on my blog.

I’ve found couple of projects that could help:

These projects looks to be a good fit, however I would have adapt the CI part. If not I would be checking my current online version and not the latest changes, one idea could be to spin up a local web server and test again it. Or I could do deploys on Pull Requests for example.


There is a simpler way: The posts are written in markdown so it will check all the posts, so it’s not checking everything but the most important!
Moreover, it’s super simple to add I just have to copy/paste an already existing github action.

name: Check Markdown links
on: push
    runs-on: ubuntu-latest
    - uses: actions/checkout@master
    - uses: gaurav-nelson/github-action-markdown-link-check@v1

Tada! I now have a broken link checker, well does it work?
I’ve added a broken link in a .md file and the job failed looks good so far :)
