Val Town Search

Search for vals using the Github API.

Either use the provided UI, or the query param:

https://val-town-search.pomdtr.me/search?q=fetchJSON

How does it work ?

I've wrote about it!

Todos

  • Embed the results in the UI
  • Refresh the vals on a cron using a github action
  • Improve layout on small screens
  • Support json Accept header
  • Add pagination params
  • Allow to filter by authors
