child process ipc

/!\ require nodejs v14 (if you use docker make sure docker have the right version for node) /!\

actually the path in index is './child/child.js' but on alt:v this relative path not work change the path if you need to use in alt

Init

1) init child process

import Fork from './class/Fork.js'
const childProcess = new Fork("./resources/redside/server/fork/child/child.js") //path start in folder of altv exec

Event

1) add event this work in two way

(on main program)

import Fork from './class/Fork.js'
const childProcess = new Fork("./resources/redside/server/fork/child/child.js")
childProcess.on("myEvent", function(data,data2){
    console.log("passe dans my event")
    console.log(data,data2)
})

if you need to send event when you child process is created use ready event

async function test(){
    const rslt = await childProcess.sendAsync("addition", 1,2)
    console.log("result of addition is ", rslt)
    childProcess.send("myEvent")

    const [calc,secondParameter] = await childProcess.sendAsync("twoParameterExemple",10,10)
    console.log(calc)
    console.log(secondParameter)
    childProcess.sendCb("addition", (value)=>{
        console.log("passe dans send cb value = ", value)
    }, 5,5)
}

childProcess.on('ready', async () => {
    test()
})
//if you make test call here he doesn't work use ready
//test()

(on child program)

import Ipc from '../class/Ipc.js'
const ipc = new Ipc(process)

ipc.on("myEvent", ()=>{
    console.log("call de myEvent on child process")
    console.log("call de myEvent on child process 2")
})

ipc.onCallBack("addition", (data1,data2)=>{
    return [data1 + data2]
})

ipc.send('myEvent',5,6)

benchmark

for callback response with ipc

on alt dev branch 1ms

on alt release branch (slow due to event loop problem on release branch) 50ms

on node program (it's very fast on node program) 0.2000 ms
