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 🙏

distribute-group-to-array

將分組資料均匀分發到多個陣列中,適用於負載均衡和任務分配場景。

Distribute grouped data evenly into multiple arrays, suitable for load balancing and task distribution scenarios.

功能說明 / Features

  • distributeGroupToArrayCore: 將群組分發到多個二維陣列
  • distributeGroupToArray: 將群組分發並扁平化為單一陣列
  • mapToRecord: 將 Map 轉換為 Record

安裝 / Install

yarn add distribute-group-to-array
yarn-tool add distribute-group-to-array
yt add distribute-group-to-array

使用範例 / Usage Examples

基本使用 / Basic Usage

import distributeGroupToArray from 'distribute-group-to-array';

// 將兩個群組的資料交替分發
const result = distributeGroupToArray({
  groupA: ['a1', 'a2', 'a3'],
  groupB: ['b1', 'b2']
});

console.log(result); // => ['a1', 'b1', 'a2', 'b2', 'a3']

分發到多個陣列 / Distribute to Multiple Arrays

import { distributeGroupToArrayCore } from 'distribute-group-to-array';

// 分發到 3 個陣列
const result = distributeGroupToArrayCore({
  groupA: ['a1', 'a2', 'a3', 'a4'],
  groupB: ['b1', 'b2'],
  groupC: ['c1']
}, { groupArraySize: 3 });

console.log(result);
// => [['a1', 'b1', 'c1'], ['a2', 'b2'], ['a3', 'a4']]

自訂初始化 / Custom Initialization

import { distributeGroupToArrayCore } from 'distribute-group-to-array';

// 自訂初始化的陣列數量
const result = distributeGroupToArrayCore({
  users: ['u1', 'u2', 'u3', 'u4', 'u5', 'u6']
}, {
  init: () => [[], [], []],
});

console.log(result);
// => [['u1', 'u4'], ['u2', 'u5'], ['u3', 'u6']]

使用 Map 輸入 / Using Map Input

import distributeGroupToArray from 'distribute-group-to-array';

const map = new Map([
  ['groupA', ['a1', 'a2']],
  ['groupB', ['b1', 'b2']]
]);

const result = distributeGroupToArray(map);
console.log(result); // => ['a1', 'b1', 'a2', 'b2']

應用情境 / Application Scenarios

  1. 負載均衡: 將任務均匀分配到多個 worker 處理
  2. 資料分頁: 將大型資料集分發到多個頁面顯示
  3. 輪詢分發: 實現簡單的輪詢調度和请求分发
  4. 批次處理: 將資料均匀分成多個批次處理
