Package contains the following modules:
Decodes any Json onto a generic model:
type Json
= JString String
| JBool Bool
| JInt Int
| JFloat Float
| JNull
| JObj (Dict String Json)
| JArr (List Json)
The usual approach in Elm is to write Json.Decode
logic that decodes onto a specific user defined type (or type alias).
This is a stronger approach and leads to nicely typed data models and better programs, and this approach should not
generally be abandoned in favor of using this generic decoder.
There are a couple of situations where a generic decoder can be useful:
If you wanted to validate an arbitrary json against an arbitrary json-schema - which of course has its own fixed schema, that you would decode and write a program around.
If you wanted to write a UI to help a user understand and work with arbitrary JSON. Say to visualise it or search it.
Programs that take JSON and try to infer its schema, or automatically map it to a data model.
If you wanted to write a JSON diff program, that can handle any JSON inputs.
