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 🙏

@ongkir-sdk/cache-memory

v0.2.1

Published

In-memory cache wrapper untuk provider ongkir-sdk — cache hasil getRates agar tidak membebani API cek ongkir.

Readme

@ongkir-sdk/cache-memory

Paket tidak resmi — tidak berafiliasi dengan atau didukung secara resmi oleh Biteship, Komerce, RajaOngkir, Shipper, atau penyedia logistik mana pun.

Wrapper caching in-memory untuk ShippingProvider apa pun di @ongkir-sdk/core. Berguna kalau kamu memanggil getRates() berulang kali untuk request yang sama (mis. saat user mengetik kota tujuan di form checkout) dan tidak mau membebani API provider — terutama provider yang menghitung biaya secara real-time.

Instalasi

bun add @ongkir-sdk/cache-memory

Penggunaan

import { MemoryCacheProvider } from '@ongkir-sdk/cache-memory'
import { ShipperProvider } from '@ongkir-sdk/shipper'

const shipper = new ShipperProvider({ apiKey: 'YOUR_API_KEY' })
const provider = new MemoryCacheProvider({ provider: shipper })

const rates = await provider.getRates({
  origin: { postalCode: '10110' },
  destination: { postalCode: '40111' },
  items: [{ weightGrams: 1000, quantity: 1 }],
})

Yang di-cache

Hanya getRates() yang di-cache. trackShipment(), createShipment(), dan parseWebhook() selalu diteruskan langsung ke provider — hasilnya tidak pernah di-cache.

Kunci cache dibuat dari request ternormalisasi (origin, destination, dan items). Request yang sama akan memakai entri yang sama.

Konfigurasi

| Opsi | Default | Deskripsi | | --- | --- | --- | | provider | — | Instance ShippingProvider yang dibungkus. Wajib. | | ttlMs | 300_000 (5 menit) | Umur cache dalam ms. Set 0 untuk mematikan caching. | | now | Date.now | Supplier waktu, untuk testing. |

API

  • getRates(params) — hasil di-cache selama TTL; hasil yang dikembalikan adalah salinan, jadi mutasi oleh caller tidak mencemari cache. Entri di-evict otomatis dari memori setelah TTL lewat.
  • trackShipment(id, options?) — delegasi langsung.
  • parseWebhook(payload, headers) — delegasi langsung.
  • createShipment(params) — delegasi langsung.
  • clear() — kosongkan seluruh cache secara manual.

FAQ

Apa yang di-cache? Hanya hasil getRates(). trackShipment(), createShipment(), dan parseWebhook() selalu diteruskan langsung ke provider.

Berapa lama hasil cache disimpan? TTL default 5 menit (ttlMs); set 0 untuk mematikan caching. Entri di-evict otomatis setelah TTL lewat.

Runtime apa yang didukung? Node ≥18, Bun, Deno, dan Cloudflare Workers — murni Web-standard API, tanpa dependency eksternal.

Tests

bun run test
