SyncFunction

A mutex for synchronization using promises

Usage as in sequence lock

const {SyncFunction} = require('syncfunction') // or SyncQueue

const sync = SyncFunction()
sync(async()=>{
    await [...] // only one at a time
})
await sync(async()=>{
    await [...] // only one at a time
})

Usage as throat

A throat is an asyncronous function that executes work in the background without awaiting on the result. A throat guaruntees no more than n functions will be executed at a time.

const sync = ThroatFunction(2)
await sync(async()=>{
    await [...] // only 2 at a time
})
await sync(async()=>{
    await [...] // only 2 at a time
})
await sync(async()=>{
    await [...] // only 2 at a time
})

// wait until done
await sync(null)

Usage in a throat queue

A throat is an asyncronous function that executes work in the background with each function call returning an awaitable promise for the underlying call. A throat guaruntees no more than n functions will be executed at a time.
