MagicJSON
A compiletime JSON parser generator for Crystal.
The main purpose that MagicJSON is supposed to fulfill is to make working with payloads that need external Crystal data (i.e. objects not in the payload that need to be passed all the way from from_json
to an instance variable) painless, or at least much less painful than with the builtin JSON.mapping
.
MagicJSON also supports inheritance and mixins naturally. You can, for example, have a class that defines a field, a module that defines another field and another module that defines yet another field. If you extend that class and include both modules in another class you will have 3 fields.
Installation
Add this to your application's shard.yml
:
dependencies:
magicjson:
gitlab: zatherz/magicjson
Usage
require "magicjson"
Define a User with a username and a bot?
field:
require "magicjson"
struct User
include MagicJSON
json_defaults getter: true # MagicJSON supports customizable defaults!
field username : String
field bot? : Bool = true, key: "bot" # As opposed to JSON.mapping, you can also easily define fields ending in question marks or exclamation marks.
end
Examples
A couple of examples are available in the examples/
directory.
