execute batches of HTTP requests in parallel

Parallel HTTP request execution

  • Takes values from a text file and converts them into HTTP requests (against an echo service with a request execution time of 150ms - 200ms).
  • splits the text file into chunks of $CHUNKS number of items which get executed in sequence by a single curl invocation that reuses the connection (reducing TCP and TLS overhead)
  • $PARALLEL number of chunks are executed concurrently by sem (of GNU parallel)


The demo generates 100 requests. Each request's response is stored to disk (because why not).

Looking to find low powered devices to disable animations and stuff
View browser.js
import platform from 'platform'
export const OS = ( || '').toLowerCase()
export const ANDROID = OS === 'android'
export const IOS = OS === 'ios'
export const VERSION = parseFloat(platform.version)
export const MAJOR_VERSION = Math.floor(VERSION)

How best to encapsulate data retrieval and conversion stuff as shown in the gustav.mixin.js demo, so that it can be easily used in multiple components like gustav.vue?

The problem here is that from the component's perspective we're only interested in providing ottoId and receiving gustav. All other properties from data, computed, methods are at best irrelevant to the component - at worst may cause conflicts.

Is there any sane way I can stay in the "how a mixin would do it" kind of code, but achieve only the export of computed.gustav, watch.ottoId and created?
