Pure-Swift JSON parser & formatter. Fully streamable input and output. Linux & OS X ready. Replacement for NSJSONSerialization.
Jay conforms to the following specifications:
- JSON RFC4627
- Open Swift C7 JSON with the use of Jay-C7
For extra convenience functions when working with the JSON enum, check out Jay-Extras.
We all use JSON. Especially when writing server-side Swift that needs to run on Linux. #0dependencies
This is my take on how a JSON parser should work. This is not another JSON mapping utility library. This is an actual JSON parser and formatter. Check out the code, it was fun to write 😇
- Parsing: data -> JSON object
- Formatting: JSON object -> data
- Pretty printing
- Streaming input and output, low memory footprint
do { //get data from disk/network let data: [UInt8] = ... //ask Jay to parse your data let json = try Jay().jsonFromData(data) // JSON //or let json = try Jay().anyJsonFromData(data) // [String: Any] or [Any] //if it doesn't throw an error, all went well if let tasks = json.dictionary?["today"]?.array { //you have a dictionary root object, with an array under the key "today" print(tasks) //["laundry", "cook dinner for gf"] } } catch { print("Parsing error: \(error)") }do { //get a json object (works for both [String: Any] and typesafe versions - JSON) //ask Jay to generate data let anyContainer = ... // [String: Any] or [Any] let data = try Jay(formatting: .prettified).dataFromJson(any: json) // [UInt8] //or let json: JSON = ... // JSON let data = try Jay(formatting: .prettified).dataFromJson(json: json) // [UInt8] //send data over network, save to disk } catch { print("Formatting error: \(error)") }.Package(url: "https://github.com/czechboy0/Jay.git", majorVersion: 1)Please note that this project is released with a Contributor Code of Conduct.
