Custom Serializers

import { createSerializer } from "katman/plugins"

const serializer = createSerializer()
  .register("Date", {
    test: (v) => v instanceof Date,
    serialize: (v) => v.toISOString(),
    deserialize: (v) => new Date(v),
  })
  .register("BigInt", {
    test: (v) => typeof v === "bigint",
    serialize: (v) => v.toString(),
    deserialize: (v) => BigInt(v),
  })

// As JSON replacer/reviver
const json = JSON.stringify(data, serializer.replacer)
const parsed = JSON.parse(json, serializer.reviver)

// Or use the convenience methods
const json2 = serializer.stringify(data)
const parsed2 = serializer.parse(json2)
