Kaja
Kaja is a type-safe JSON parser/decoder for Kotlin inspired by Argo and SwiftyJSON.
val json: Result<Json, JsonException>
= Json.parse(jsonString)
val person: Result<Person, JsonException>
= curry(::Person) mp
json["firstName"].string ap
json["middleName"].string.optional ap
json["lastName"].string ap
json["age"].int ap
json["knownFor"].list(Json::string)
The code above is one to parse JSONs formatted like the following
{
"firstName": "Albert",
"lastName": "Einstein",
"age": 76,
"knownFor": [
"General relativity",
"Special relativity",
"Photoelectric effect",
"Mass-energy equivalence",
"Theory of Brownian motion"
]
}
and decode it to a Person
.
data class Person(
val firstName: String,
val middleName: String?,
val lastName: String,
val age: Int,
val knownFor: List<String>
)
Naming
Kaja is derived from caja (box) in Spanish. Kaja's K and j stand for Kotlin and JSON respectively.
