Scotty-0.21 just released!

ocramz · December 17, 2023, 4:12pm

Happy to share our latest work on scotty: scotty: Haskell web framework inspired by Ruby's Sinatra, using WAI and Warp

This is a smaller release for consolidating the changes started in 0.20 :

new distinct modules for strict and lazy text parameters (.Trans.Strict and .Trans.Lazy)
the exceptions system and HTTP error reporting has been clarified (e.g. you cannot catch a Redirect)
more standard naming (“capture” → “path parameter”)
a number of fixes and QoL improvements (url-escaped path parameters, query-rewriting middlewares now work properly etc.)
lots of new documentation (doctests!)

## next [????.??.??]


## 0.21 [2023.12.17]
### New
* add `getResponseHeaders`, `getResponseStatus`, `getResponseContent` (#214)
* add `captureParamMaybe`, `formParamMaybe`, `queryParamMaybe` (#322)
* add `Web.Scotty.Trans.Strict` and `Web.Scotty.Trans.Lazy` (#334)
* renamed `captureParam`, `captureParamMaybe`, and `captureParams` to `pathParam`, `pathParamMaybe`, `pathParams` respectively, keeping the old names as their synonyms (#344)

### Deprecated
* deprecate `rescue` and `liftAndCatchIO` (#332)
* Deprecate `StatusError`, `raise` and `raiseStatus` (#351)

### Fixes
* Reverted the `MonadReader` instance of `ActionT` so that it inherits the base monad (#342)
* Scotty's API such as `queryParam` now throws `ScottyException` rather than `StatusException`.
  Uncaught exceptions are handled by `scottyExceptionHandler`, resembling the existing behaviour
