Serialize ImmutableJS data

Installation

npm install --save remotedev-serialize

Usage with ImmutableJS data structures

Just pass the Immutable library to our class:

import Immutable from 'immutable';
import Serialize from 'remotedev-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 'remotedev-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 'remotedev-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
