Using Schema for Message Encoding/Decoding with Different Naming Conventions

const CallMessage = S.struct({
  actionType: S.string,
  action: S.string
})
export type CallMessage = S.To<typeof CallMessage>
export const parseCallMessage = S.parse(CallMessage)
export const encodeCallMessage = S.encode(CallMessage)

{
  "action_type": "hello",
  "action": "world"
}
