Defined in:

Overview

Serializes messages to and from JSON-native structures — Hashes, Arrays, Strings, numbers, booleans, nil — ready for JSON.dump. The codec never writes bytes itself, so the transport decides how they are stored or framed.

codec = Sourced::Message::JSONCodec.default.compile!
codec.encode(message)  # => JSON-native Hash
codec.decode(attrs)    # => the message

Plumb::Codec::JSON is a process-wide global, so an encoder registered on it teaches every JSON codec in the process at once:

Plumb::Codec::JSON.encoder(MoneyEncoder)

Register at load time — a codec compiled before an encoder arrives never sees it.

See Codec for the machinery, and for the seams a subclass overrides.
