jest-serializer

DEPRECATED: Use v8 APIs directly: https://nodejs.org/api/v8.html#serialization-api

Module for serializing and deserializing object into memory and disk. The Node core v8 implementations are used. This seriializer have the advantage of being able to serialize Map, Set, undefined, NaN, etc..

Install

1$ yarn add jest-serializer

API

Three kinds of API groups are exposed:

In-memory serialization: `serialize` and `deserialize`

This set of functions take or return a Buffer. All the process happens in memory. This is useful when willing to transfer over HTTP, TCP or via UNIX pipes.

1import {deserialize, serialize} from 'jest-serializer';
2
3const myObject = {
4  foo: 'bar',
5  baz: [0, true, '2', [], {}],
6};
7
8const buffer = serialize(myObject);
9const myCopyObject = deserialize(buffer);

Synchronous persistent filesystem: `readFileSync` and `writeFileSync`

This set of functions allow to send to disk a serialization result and retrieve it back, in a synchronous way. It mimics the fs API so it looks familiar.

1import {readFileSync, writeFileSync} from 'jest-serializer';
2
3const myObject = {
4  foo: 'bar',
5  baz: [0, true, '2', [], {}],
6};
7
8const myFile = '/tmp/obj';
9
10writeFileSync(myFile, myObject);
11const myCopyObject = readFileSync(myFile);
