SharedArray

Int32Array with infinite length using SharedArrayBuffer

Installation

Run npm install sharedarray in your project

Require using

const SharedArray = require('sharedarray')

Usage

Example

let array = new SharedArray()

await array.set(10, 500)
let a = await array.get(10) // a = 500

await array.concatenate(0, [1, 2, 3])
let x = await array.get(0) // x = 1
let y = await array.get(1) // y = 2
let z = await array.get(2) // z = 3

let array2

//export array
let exportData = array.export((number, buffer) => {
    array2.sync(number, buffer)
})

//send that exportData to another thread/worker and then re-recreate array object
array2 = new SharedArray(exportData, (number, buffer) => {
    array.sync(number, buffer)
})

let b = await array2.get(10) // b = 500

The two objects need to be able to sync with each other over different threads. You therefore need to pass a sync function upon exporting, you will need to send the two parameters to the other objects sync function. That also needs to happen in reverse, so when creating the second array you need to pass the sync function of the first object.
When using workers you will need to send this data using the postMessage function. The functions give you a the indexNumber and the buffer, this not actual data but rather a pointer.
