JsonEncoder

Configuration-bound encoder bundles.

Provides extension methods for encoding values.

Summons an encoder instance for type A.

val stringEnc = JsonEncoder[String]

Derives an encoder for type A using Scala 3 mirrors.

Supports both product types (case classes) and sum types (sealed traits). Enabled via derives JsonEncoder clause.

case class Point(x: Int, y: Int) derives JsonEncoder
sealed trait Color derives JsonEncoder
case object Red  extends Color
case object Blue extends Color

Encodes BigDecimal as JString or JNumber depending on config.

Encodes BigInt as JString or JNumber depending on config.

Encodes Boolean as JBool.

Derives an encoder for product types (case classes) by encoding each field into a JObject.

Derives an encoder for sum types (sealed traits/enums) using wrapped-by-type-key discriminator.

Encodes Double as JNumber.

Encodes Instant as ISO-8601 string truncated to milliseconds.

Encodes Int as JNumber.

Encodes List as JArray.

Encodes Long as JNumber.

Encodes Map as JObject by converting keys with JsonKeyCodec to field names.

Encodes Option as the encoded inner value or JNull for None.

Encodes String as JString.

Encodes Vector as JArray.
