Deprecation

Introduction

Say, you have an async function with only one argument: options, like request-facebook, now you can leverage this package to easily enhance that function with retry, rate limit and parallel limit.

Installation

npm i run-control

Usage

const {compose, withDefaultOptions, withRetry, withRateLimit, withParallelLimit} = require('run-control')
const requestFacebook = require('request-facebook')

// all features are implemented as high order functions
// so you can just compose them
const myRequestFacebook = compose(
  // feed default options
  withDefaultOptions({accessToken: ...}),
  
  // retry if failed
  withRetry({times: 5}),
  
  // limit max task in parallel
  withParallelLimit(1000),
  
  // limit dispatched tasks per second
  withRateLimit(100),
)(requestFacebook)

// now you can call the enhanced function with all the features you added
for (let i = 0; i < 10000; i++) {
  myRequestFacebook({...}).then(...).catch(...)
}
