# `JSONCodec`
[🔗](https://github.com/dannote/json_codec/blob/main/lib/json_codec.ex#L1)

Compile-time generated codecs for JSON-shaped Elixir structs.

`JSONCodec` is not a JSON parser. It uses `Jason` for JSON parsing and focuses on
the part application code usually repeats by hand: turning decoded string-keyed maps
into nested structs with defaults, aliases, computed fields, explicit atom policy, and
schema export.
