Marshalling

Serializing and deserializing data

Handling arbitrary data

Since everything sent over the wire is converted to JSON we can't send anything and get it returned the same. For example Date will lose it's structure once converted to string.

middleware
  .call(() => new Date) 

To handle returning/sending any data we can use devalue.

Devalue option

Fortunately devalue already takes care of Date, but here's how we can do it ourselves in a shared options file.

kavi/options.ts
import { createOptions, devalueOption } from 'kavi'

export const options = createOptions({
  devalue: {
    Date: devalueOption
      .stringify((value) => {
        if (value instanceof Date) {
          return date.toString()
        }
      })
      .parse((value) => new Date(value))
  }
})
