@emit-js/wait

emit async wait

Install

npm install @emit-js/emit @emit-js/wait

Setup

const emit = require("@emit-js/emit")()
require("@emit-js/wait")(emit)

Usage

Wait for two async processes to call emit.wait:

async function test() {
  await emit.wait({ count: 2 })
}

await test() // never finishes

await Promise.all([test(), test()]) // finishes

Why?

Sometimes you want to call the same function multiple times asynchronously, and you want each call to wait for certain "checkpoints" across all calls.

As long as you know how many total calls there are (count), you can wait for each call to reach emit.wait before continuing.

Each emit.wait must receive a unique prop to begin a new counter.
