asyncctx

node-async-context

This module allows you to create a asynchronouse execution context for JavaScript or TypeScript

NOTE: This module is based on async-hook, which in turn is based on the undocumented API AsyncWrap

This is the reason why async-hook will show this warning on startup:

WARNING: 'you are using async-hook which is unstable.'

NOTE: Your contribution is highly welcome!

Introduction

To give you an idea of how node-async-context is supposed to be used:

import { ContinuationLocalStorage } from 'asyncctx';

class MyLocalStorage {
  value: number;
}

let cls = new ContinuationLocalStorage<MyLocalStorage>();

process.nextTick(() => {
  cls.setData({ value: 1}); // value should be 1 in the current execution context and below
  process.nextTick(() => {
    let curr1 = cls.getData(); // value is 1
    cls.setData({ value: 2}); // value should be 2 in the current execution context and below
    process.nextTick(() => {
      let curr2 = cls.getData(); // value is 2
    });
  });
  process.nextTick(() => {
    let curr3 = cls.getData(); // value is 1
  });
});
