@exodus/serialization

Serialize and deserialize data, e.g. for sending over the wire. Supports arrays, Date, Buffer, Uint8Array, BigInt out of the box, as well as the ability to extend with custom types.

Install

``sh
yarn add @exodus/serialization
`

Usage

$3

`js
import createSerializeDeserialize from '@exodus/serialization'

const { serialize, deserialize } = createSerializeDeserialize()

const original = { hello: Buffer.from('world') }
const fromOverTheWire = deserialize(serialize(original))
expect(fromOverTheWire).toEqual(original)
`

To add your own types, provide a type definition consisting of

- type: a unique string identifier for the type
- test: a function that returns true if the value is an instance of the type
- serialize: a function that serializes a value of the type
- deserialize: a function that deserializes a value of the type

For example, if BigInt serialization wasn't built-in, you could add support as follows:

`js
const { serialize, deserialize } = createSerializeDeserialize([
{
type: 'bigint',
test: (v) => typeof v === 'bigint',
serialize: (v) => v.toString(),
deserialize: (v) => BigInt(v),
},
])

const original = {
question: 'what is the biggest number in the universe?',
answer: BigInt(42),
}

const fromOverTheWire = deserialize(serialize(original))
expect(fromOverTheWire).toEqual(original)
