Serialize ImmutableJS data

Installation

yarn add @redux-devtools/serialize

Usage with ImmutableJS data structures

Just pass the Immutable library to our class:

import Immutable from 'immutable';
import Serialize from '@redux-devtools/serialize';
const { stringify, parse } = Serialize.immutable(Immutable);

const data = Immutable.fromJS({ foo: 'bar', baz: { qux: 42 } });
const serialized = stringify(data);
console.log(serialized);
// {"data":{"foo":"bar","baz":{"data":{"qux":42},"__serializedType__":"ImmutableMap"}},"__serializedType__":"ImmutableMap"}
const parsed = parse(serialized);
console.log(Immutable.is(parsed, data));
// true

See the tests for more examples of usage.

Usage with ImmutableJS Record classes

To parse a Record class back, you need to specify a reference to it:

import Immutable from 'immutable';
import Serialize from '@redux-devtools/serialize';

const ABRecord = Immutable.Record({ a: 1, b: 2 });
const { stringify, parse } = Serialize.immutable(Immutable, [ABRecord]);

const myRecord = new ABRecord({ b: 3 });
const serialized = stringify(myRecord);
console.log(serialized);
// {"data":{"a":1,"b":3},"__serializedType__":"ImmutableRecord","__serializedRef__":0}
const parsed = parse(serialized);
console.log(Immutable.is(parsed, myRecord));
// true

Passing custom serialization functions

You can pass custom replacer and reviver functions to Serialize:

import Immutable from 'immutable';
import Serialize from '@redux-devtools/serialize';

function customReplacer(key, value, defaultReplacer) {
  if (value === 1) {
    return { data: 'one', __serializedType__: 'number' };
  }
  return defaultReplacer(key, value);
}

function customReviver(key, value, defaultReviver) {
  if (
    typeof value === 'object' &&
    value.__serializedType__ === 'number' &&
    value.data === 'one'
  ) {
    return 1;
  }
  return defaultReviver(key, value);
}

const { stringify, parse } = Serialize.immutable(
  Immutable,
  null,
  customReplacer,
  customReviver
);

const map = Immutable.Map({ a: 1, b: 2 });
const serialized = stringify(map);
console.log(serialized);
// {"data":{"a":{"data":"one","__serializedType__":"number"},"b":2},"__serializedType__":"ImmutableMap"}
const parsed = parse(serialized);
console.log(Immutable.is(parsed, map));
// true
