mobx-keystone/src/actionMiddlewares/actionSerialization/arraySerializer.ts

A MobX powered state management solution based on data trees with first class support for TypeScript, snapshots, patches and much more

import type { IObservableArray } from "mobx"
import { isArray, namespace } from "../../utils"
import { ActionCallArgumentSerializer, cannotSerialize } from "./core"

export const arraySerializer: ActionCallArgumentSerializer<any[] | IObservableArray<any>, any[]> = {
  id: `${namespace}/array`,

  serialize(value, serialize) {
    if (!isArray(value)) {
      return cannotSerialize
    }

    // this will also transform observable arrays into non-observable ones
    return value.map(serialize)
  },

  deserialize(arr, deserialize) {
    return arr.map(deserialize)
  },
}
