asyncforge

asyncforge allows you to remove singletons from your codebase with the
use of AsyncLocalStorage.

It provides helpers to build Next.js-style helpers to access "singletons".

Install

``sh
npm i asyncforge
`

Usage

`js
import { create, memo } from 'asyncforge.js'

const a = memo()
const b = memo()

const store = create()

store.run(() => {
a.set(42)
b.set(123)

// simulate an event loop turn
setImmediate(() => {
console.log('-- first event loop turn --')
console.log('a', a())
console.log('b', b())
})
})

create(() => {
a.set(43)
b.set(321)

// simulate an event loop turn
setImmediate(() => {
console.log('-- second event loop turn --')
console.log('a', a())
console.log('b', b())

store.run(() => {
setImmediate(() => {
console.log('-- third event loop turn --')
console.log('a', a())
console.log('b', b())
})
})

setImmediate(() => {
store.enterWith()
console.log('-- fourth event loop turn --')
console.log('a', a())
console.log('b', b())
})
})
})
`

TypeScript

You can call the asyncforge functions in a type-safe way:

`ts
import { create, memo } from "asyncforge";
const memoNum = memo();
const test = memo();

const store = create()

store.run(() => {
// This is okay for TypeScript, since you're passing a number
memoNum.set(123);


// This will not build
memoNum.set('wrong');
})

store.run(() => {
// The result var will be of type number
const result = memoNum()
})
``
