Building a blog using github issues

I wanted to see if I could write blog posts using github issues, and have them be published on the web. You can!

Create a jekyll site

  cd $(mktemp -d)
  bundle init
  bundle add jekyll
  bundle exec jekyll new issue-blog
  cursor issue-blog

Then inside

  bundle add jekyll-compose
  bundle
  jekyll s

Create the repo

  git init
  git add .
  git commit -m "initial commit"
  gh repo create wschenk/issue-blog --public
  gh repo edit -d "Playground to make posts and comments from github issues"
  git remote add origin https://github.com/wschenk/issue-blog
  git push origin main

Add the secret

  gh auth token | gh secret set AUTH_TOKEN

Issue to Post workflow

When you open or edit and issue, we check out the repo, and then create a file in the _posts directory can fill in the information

Once that's done, we trigger a deploy action using peter-evans/repository-dispatch to trigger the second build action.

Deploy to pages

Here we check out the code and deploy it to github pages. We replace the baseurl with the base_path that we get from configure-pages, so its smart enough to know if you have it on a custom domain or as a subdirectory.
