pnpm install --save xstream-backoff

Creates an xstream Stream that emits numbers in exponential backoff periods of time.

Description

Creates a stream that periodically emits incremental numbers, where the interval of time varies exponentially.

Marble diagram:

           backoff(500, 2, 6000)
-0---1-------2---------------3-----------------------4----...
 
intervals:
500ms
    1s
            2s
                            4s
                                                    6s

Arguments:

• interval: initial interval of time expressed in milliseconds
• factor: (optional, default 2) how much to multiply the previous interval each time the stream emits
• maximum: (optional, default Infinity) the maximum interval at which to limit the interval calculation

Usage

import backoff from 'xstream-backoff'
 
const source = backoff(500, 2, 6000).take(5)
 
source.addListener({
  next: i => console.log(i),
  error: err => console.error(err),
  complete: () => console.log('completed')
})
