json.encode and json.decode

Syntax

ue.json.encode(value: any) -> string?, error?
ue.json.decode(text: string) -> any?, error?

Supported values

JSON-compatible nil, booleans, numbers, strings, arrays, and string-keyed tables are supported. Tables may be nested up to 32 levels and cannot contain cycles.

Example

local text = assert(ue.json.encode({
    name = "Rowan",
    stats = { health = 100 },
    tags = { "npc", "merchant" }
}))

local value = assert(ue.json.decode(text))
print(value.name, value.stats.health)

Notes

• Lua strings are binary-safe, but JSON strings must contain valid JSON text when decoding.
• An empty Lua table has no key shape and is encoded as an empty JSON array.
• Unsupported userdata, functions, cyclic tables, invalid JSON, and excessive nesting return nil, error.
