My first Haskell web app: a GroupMe bot which could, hypothetically, be used to deliver on-demand random tomato images to a GroupMe chat, but which should, of course, only be used when adapted to follow the terms of service of the Unsplash API
Best practices meet a best-effort development cycle: I wrote this in one day, following best practices when I knew about them and when it wasn't too much work.
I structured the app with the ReaderT design pattern, and, as always, adhered to the tenets of type-driven design.
Things to do differently next time:
- Use Servant instead of WAI + Warp
- Don't commit hardcoded access tokens (they are no longer valid)
- Don't give up so early on error handling
