memoryshare is a module allow Node.js developers share memory between different process

It's high performance when share data is huge than transfer data by IPC

• High performance ✨
• Simple api interface 💗

$ yarn bench

ipc:
  34 ops/s, ±55.24%       | slowest, 99.73% slower

sharememory:
  12 412 ops/s, ±44.21%   | fastest

Finished 2 cases!
Fastest: sharememory
Slowest: ipc
✨  Done in 28.89s.

$ npm i memoryshare # or yarn add memoryshare

Note: You need to make sure that the compilation environment of the dynamic library is the same as the installation and runtime environment of the memoryshare call.

memoryshare support for data that can be serialized as string

Here is an example to guide how to share string data between different process

// main.js
import { fork } from 'child_process'
import { init, setString, getString, clear } from 'memoryshare'

const memId = "string.link"

init(memId, 4096) // init share memory block with max size,each memId should be called only once

function generateBigString() {
  let bigStr = '';
  for (let i = 0; i < 1; i++) {
    bigStr += 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. ';
  }
  return bigStr;
}

setString(memId, generateBigString())

fork('./child')

// child.js
const memId = "string.link"
const data = getString(memId)
