jsonErrors :: Application -> Application Source #
Converts errors from plaintext to json.
Example: a plaintext json parsing error returns a 400 status code and a message: > Error in $: key "firstName" not present
Using this middleware it would look like this: > { > "status": 400, > "error": "Error in $: key "firstName" not present" > }
