Usage

Example for BarrierInterval

const { Barrier, BarrierFactory, BarrierOperator } = require('node-barrier')

// create barrier to block operation count to 10 per second
const barrier = BarrierFactory.makeBarrierInterval({
            cleanIntervalInMills: 1000,
            maxCount: 10
        })

await BarrierOperator.wait(barrier)
barrier.increaseCounter()
// perform you operation

Example for BarrierAnd

const { Barrier, BarrierFactory, BarrierOperator } = require('node-barrier')

// create barrier to block operation count to 10 per second
const barrier1 = BarrierFactory.makeBarrierInterval({
            cleanIntervalInMills: 1000,
            maxCount: 10
        })
const barrier2 = BarrierFactory.makeBarrierInterval({
            cleanIntervalInMills: 2000,
            maxCount: 10
        })
const barrier = BarrierOperator.and(barrier1, barrier2)

const blockTime = barrier.computeBlockTimeInMills()
await BarrierOperator.wait(barrier)
barrier.increaseCounter()
// perform you operation

Example for BarrierOr

const { Barrier, BarrierFactory, BarrierOperator } = require('node-barrier')

// create barrier to block operation count to 10 per second
const barrier1 = BarrierFactory.makeBarrierInterval({
            cleanIntervalInMills: 1000,
            maxCount: 10
        })
const barrier2 = BarrierFactory.makeBarrierInterval({
            cleanIntervalInMills: 2000,
            maxCount: 10
        })
const barrier = BarrierOperator.or(barrier1, barrier2)

await BarrierOperator.wait(barrier)
barrier.increaseCounter()
// perform you operation
