If you have a Jekyll static site, this plugin may help you automatically generate short links for every page. I'm using this plugin for my blog.

Install it first (you need Ruby 3+ and Jekyll 3+):

$ gem install jekyll-shorts

Then, add this to _config.yml:

plugins:
  - ... your other plugins here ...
  - jekyll-shorts
shorts:
  permalink: :year:month:day:letter.html

Here, every page in the site will get a sibling with the name :year:month:day.html, which will redirect to the page itself. You can use:

• :year - the short form of the year of the post, like 23 or 76
• :month - the month of the post, like 01 or 12
• :day - the day of the post, like 07 or 29
• :letter - a unique English letter for a short URL, like a, b, etc.

If you don't use the :letter, you may end up with duplicated URLs. For example, you have two pages written in 2023-11-23. Their URLs will be the same, if the permalink is :year:month:day.html, as in the example above. With the help of the :letter, two URLs become different.

Inside the Jekyll page, you can use {{ page.short-url }} for the value of the short URL.

Make a fork and then test it locally like this:

$ bundle update
$ bundle exec rake

If it works, make changes, test again, and then submit a pull request.
