    Semaphore

    Naive resource management / concurrency primitive

    npm i @calebboyd/semaphore

    Example

    import { Semaphore } from '@calebboyd/semaphore'
    import { something } from './somewhere'
    
    function doSomeWork () {
      const lock = new Semaphore(10)
      while(something.isTrue) {
        lock.acquire().then(x => () => {
          something.work().then(lock.release)
        })    
      }
    }

    The semaphore will only allow 10 locks to be aquired at a time. This limits the concurrency of the asyncronous function something.work to 10

    API:

    export class Semaphore {
      constructor (count: number) {}
      acquire(): Promise<void>
      release(): void
    }
