async-revolver v1.1.0

async-revolver

A lightweight , dependency free and promise based library to manage the use of resources asynchronously by minimum interval time throttling and in cycladic manner.

For example, this library can work well with a group of API keys that are limited in calls to the API per minute - the API keys can be taken as bullets and the recourse will only be released once it reached a minimum interval.

Installation:

npm install async-revolver

Usage :

bullets - array or object of assets to be retrieved 
intervalTime - the interval between each bullet or between a full round 
includeFirstRound - skip throttling the first round or not
fullRoundInterval - throttling between full round or each bullet

Example :

• Case 1 ( includeFirstRound = false , groupInterval = true)

    let revolver = new AsyncRevolver([1,2,3],1000, false , true)
  
    let v1 = await revolver.next(); (0 seconds) //..1
    let v2 = await revolver.next(); (0 seconds) //..2
    let v3 = await revolver.next(); (0 seconds) //..3
    let v4 = await revolver.next(); (1 seconds) //..1
    let v5 = await revolver.next(); (1 seconds) //..2
    let v6 = await revolver.next(); (1 seconds) //..3
    let v7 = await revolver.next(); (2 seconds) //..1
    let v8 = await revolver.next(); (2 seconds) //..2
    let v9 = await revolver.next(); (2 seconds) //..3

• Case 2 ( includeFirstRound = true , groupInterval = true)

    let revolver = new AsyncRevolver([1,2,3],1000, true , true)
  
    let v1 = await revolver.next(); (1 seconds) //..1
    let v2 = await revolver.next(); (1 seconds) //..2
    let v3 = await revolver.next(); (1 seconds) //..3
    let v4 = await revolver.next(); (2 seconds) //..1
    let v5 = await revolver.next(); (2 seconds) //..2
    let v6 = await revolver.next(); (2 seconds) //..3
    let v7 = await revolver.next(); (3 seconds) //..1
    let v8 = await revolver.next(); (3 seconds) //..2
    let v9 = await revolver.next(); (3 seconds) //..3

• Case 3 ( includeFirstRound = false , groupInterval = false)

    let revolver = new AsyncRevolver([1,2,3],1000, false , false)
  
    let v1 = await revolver.next(); (0 seconds) //..1
    let v2 = await revolver.next(); (1 seconds) //..2
    let v3 = await revolver.next(); (2 seconds) //..3
    let v4 = await revolver.next(); (3 seconds) //..1
    let v5 = await revolver.next(); (4 seconds) //..2
    let v6 = await revolver.next(); (5 seconds) //..3
    let v7 = await revolver.next(); (6 seconds) //..1
    let v8 = await revolver.next(); (7 seconds) //..2
    let v9 = await revolver.next(); (8 seconds) //..3

• Case 4 ( includeFirstRound = true , groupInterval = false)

    let revolver = new AsyncRevolver([1,2,3],1000, true , false)
  
    let v1 = await revolver.next(); (1 seconds) //..1
    let v2 = await revolver.next(); (2 seconds) //..2
    let v3 = await revolver.next(); (3 seconds) //..3
    let v4 = await revolver.next(); (4 seconds) //..1
    let v5 = await revolver.next(); (5 seconds) //..2
    let v6 = await revolver.next(); (6 seconds) //..3
    let v7 = await revolver.next(); (7 seconds) //..1
    let v8 = await revolver.next(); (8 seconds) //..2
    let v9 = await revolver.next(); (9 seconds) //..3
