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 🙏

Google Sheets API Toolkit

Readme

@d-zero/google-sheets

Google Sheets API を型安全にラップしたライブラリ。SheetTable で「ヘッダー定義済みのテーブル」として読み書きする。

Installation

yarn add @d-zero/google-sheets @d-zero/google-auth

Usage

import { authentication } from '@d-zero/google-auth';
import { SheetTable } from '@d-zero/google-sheets';

const auth = await authentication(null, ['https://www.googleapis.com/auth/spreadsheets']);

const table = await SheetTable.create(
	'https://docs.google.com/spreadsheets/d/YOUR_SPREADSHEET_ID/edit',
	'Users',
	auth,
	{
		define: {
			name: '名前',
			email: 'メールアドレス',
			age: '年齢',
			registered: '登録日',
		},
	},
);

await table.addRecords([
	{ name: '田中太郎', email: '[email protected]', age: { value: 25 } },
]);

書式・条件付き書式・読み取り API は src/sheet-table.ts の JSDoc を参照。

重要な制約

  • 大量行のストリーミング送信は 2500 行チャンクで自動分割される(Sheets API のメモリ・タイムアウト制約への対応)
  • 遅延セル({ value: thunk })は flush 中に自動展開される。展開中に新たな遅延セルが見つかった場合は早期 flush を停止して整合性を保つ
  • onProgress コールバック内で addRecords を再入呼びしてはならない — buffer mutation 破壊で行順が壊れる
  • 同一インスタンスへの並列呼び出し禁止 — 行順・送信件数の保証は逐次呼び出し前提

理由・実装は src/sheet-table.ts および src/sheet.ts の JSDoc を参照。
