DJON is a UTF8 only relaxed superset of JSON. DJON supports round trip comments, numbers are explicitly 64bit floats and strings can contain raw binary data.

This is implimented as a c module using wasm so must be imported rather than required as it needs async to load the wasm.

A valid utf8 json file is always a valid djon file.

Djon is half man half machine:

Pretty djon makes for more human readable and editable json style configuration files and compact djon is a machine readable format that can store binary data.

import djon from "@xriss/djon"

let data = djon.load_file("filename.json") // load in djon/json format

djon.save_file("filename.json",data) // pretty json
djon.save_file("filename.compact.json",data,"compact") // compact json
djon.save_file("filename.djon",data,"djon") // pretty djon
djon.save_file("filename.compact.djon",data,"djon","compact") // compact djon

let text = djon.save(data,"djon") // save to string

let datb = djon.load(text) // load from string

// resave a djon file, pre-existing comments will be preserved
// can be used to round trip comments in config files
djon.save_comments("filename.djon",data)

if you are stuck in cjs then you may also use the nodejs import

let djon=(await import("@xriss/djon")).default
