@emit-js/wait v0.0.9
@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.
