I want to add a random article picker to my blog as another way to discover past posts, aside from categories and tags on the right side and making it easier on mobile.
I couldn’t find a simple enough solution that suits my needs after brief Googling. The options I found were either to randomize at build time, which means the article doesn’t change with each click or refresh, or to generate a JSON index, which I had trouble with probably because my lack of understanding of Hugo.
I thought such a simple feature should be achievable with just JS + HTML, so I decided to write my own. Performance shouldn’t be an issue for a blog with a few tens to thousands of articles. Here’s a solution I came up with for reference.
