Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

waitly

waitly alat ringan untuk menangani delay berbasis promise

Dilengkapi dengan fitur tambahan seperti pembatalan delay, penjadwalan tugas, dan validasi parameter. Mendukung penggunaan AbortController untuk membatalkan delay secara asinkron.

Instalasi

npm install waitly

API

waitly(milliseconds, options)

Fungsi utama untuk membuat delay berbasis promise.

Parameter:

  • milliseconds (Number): Durasi delay dalam milidetik (wajib, harus bernilai non-negatif).
  • options (Object) (Opsional):
    • returnValue (Any): Nilai yang akan dikembalikan setelah delay selesai.
    • abortSignal (AbortSignal): Objek AbortSignal untuk membatalkan delay menggunakan AbortController.

Kembalian:

  • (Promise): Sebuah promise yang selesai setelah delay. Jika abortSignal digunakan untuk membatalkan delay, promise akan gagal dengan error 'Delay dibatalkan'.
import { waitly } from 'waitly' // ESM
const { waitly } = require('waitly') // CommonJS

function runExample() {
  console.log('Start')
  waitly(2000, { returnValue: 'Selesai' }).then(() => {
    console.log('End') // Dicetak setelah 2 detik
  })
}

runExample()

waitly.cancelDelay(promise, controller)

Membatalkan delay secara manual menggunakan AbortController.

Parameter:

  • promise (Promise): Promise yang dibuat oleh waitly.
  • controller (AbortController): Objek AbortController yang terkait dengan promise tersebut.
function cancelExample() {
  const controller = new AbortController()

  const promise = waitly(5000, { abortSignal: controller.signal })

  setTimeout(() => {
    waitly.cancelDelay(promise, controller) // Membatalkan delay setelah 1 detik
  }, 1000)

  promise.catch((error) => {
    console.log(error.message) //=> 'Delay dibatalkan'
  })
}

cancelExample()

waitly.scheduleTask(task, milliseconds)

Menjadwalkan sebuah fungsi atau tugas asinkron untuk dijalankan setelah delay tertentu.

Parameter:

  • task (Function): Fungsi atau tugas yang akan dijalankan setelah delay.
  • milliseconds (Number): Waktu delay sebelum tugas dijalankan (harus bernilai non-negatif).

Kembalian:

  • (Promise): Promise yang selesai setelah tugas dijalankan.
function exampleTask() {
  console.log('Tugas dijalankan!')
}

function scheduleExample() {
  waitly.scheduleTask(exampleTask, 3000).then(() => {
    console.log('Selesai') // 'Tugas dijalankan!' akan dicetak setelah 3 detik
  })
}
