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 client for form-based data collection

Readme

@moonhr/sheets-client

English | 한국어


English

A lightweight Google Sheets client that eliminates the authentication and CRUD boilerplate when using Sheets as a form data store.
Includes service account auth, row append/query/update, and phone number cell formatting.

Installation

npm install @moonhr/sheets-client

Prerequisites

  1. Create a service account in Google Cloud Console and download the JSON key.
  2. Share the target spreadsheet with the service account email as an Editor.
  3. Set the following environment variables.
GOOGLE_SERVICE_ACCOUNT_KEY={"client_email":"...","private_key":"..."}
GOOGLE_SHEETS_SPREADSHEET_ID=1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgVE2upms
GOOGLE_SHEETS_SHEET_NAME=Sheet1

Basic Usage

import { createSheetsClient } from '@moonhr/sheets-client'

const client = createSheetsClient({
  serviceAccountKey: process.env.GOOGLE_SERVICE_ACCOUNT_KEY,
  spreadsheetId: process.env.GOOGLE_SHEETS_SPREADSHEET_ID,
  sheetName: process.env.GOOGLE_SHEETS_SHEET_NAME,
})

API

appendRow(values, range?)

Appends data to the last row of the sheet.

await client.appendRow(['2024-01-01', 'John Doe', 'Acme Corp', '01012345678'])

| Parameter | Type | Default | Description | |---|---|---|---| | values | string[] | — | Array of cell values | | range | string | 'A:Z' | Target range |


getRows(range?)

Returns all rows in the specified range. Each cell is a trimmed string.

const rows = await client.getRows('A:E')
// [['Header1', 'Header2', ...], ['Value1', 'Value2', ...], ...]

findRow(matcher, options?)

Returns the first row matching the condition, or null if not found.

Match by column index (0-based)

const result = await client.findRow({ 1: 'John Doe', 2: 'Acme Corp' })

Performs a trim + lowercase comparison on both sides.

Match with a custom function

Use this when you need numeric comparison, e.g. for phone numbers.

import { digitsOnly } from '@moonhr/sheets-client'

const result = await client.findRow((row) => {
  return row[1].trim().toLowerCase() === 'john doe' &&
         digitsOnly(row[3]) === digitsOnly('010-1234-5678')
})

Return value

{
  rowIndex: number   // 1-based sheet row number — pass directly to updateRow
  values: string[]   // Array of cell values in that row
}

options

| Option | Type | Default | Description | |---|---|---|---| | range | string | 'A:Z' | Search range | | skipHeader | boolean | true | Whether to skip the first (header) row |


updateRow(rowIndex, values, startCol?)

Updates cells in a specific row.

// Use the rowIndex returned by findRow directly
await client.updateRow(result.rowIndex, ['John Doe', 'New Corp', '01099998888'], 'B')
// → Updates range B{rowIndex}:D{rowIndex}

| Parameter | Type | Default | Description | |---|---|---|---| | rowIndex | number | — | Sheet row number (2 or greater) | | values | string[] | — | Array of replacement cell values | | startCol | string | 'A' | Starting column letter |


Utilities

import { toTextCell, digitsOnly, stripQuotes } from '@moonhr/sheets-client'

| Function | Description | Example | |---|---|---| | toTextCell(value) | Forces a phone number to be saved as text in Sheets (prevents auto-conversion to number) | '01012345678'"'01012345678" | | digitsOnly(value) | Extracts digits only (for phone number comparison) | '010-1234-5678''01012345678' | | stripQuotes(value) | Removes wrapping quotes from environment variable values | '"Sheet1"''Sheet1' |

Real-world Example — RSVP Form

import { createSheetsClient, toTextCell, digitsOnly } from '@moonhr/sheets-client'

const client = createSheetsClient({
  serviceAccountKey: process.env.GOOGLE_SERVICE_ACCOUNT_KEY,
  spreadsheetId: process.env.GOOGLE_SHEETS_SPREADSHEET_ID,
  sheetName: process.env.GOOGLE_SHEETS_SHEET_NAME,
})

// Submit registration
await client.appendRow([
  new Date().toISOString(),
  'John Doe',
  'Acme Corp',
  toTextCell('01012345678'),
  '[email protected]',
  'Agreed',
])

// Look up registration
const found = await client.findRow((row) =>
  row[1].trim() === 'John Doe' &&
  digitsOnly(row[3]) === '01012345678'
)

// Update registration
if (found) {
  await client.updateRow(
    found.rowIndex,
    ['John Doe', 'New Corp', toTextCell('01099998888'), '[email protected]'],
    'B'
  )
}

Google Sheets를 폼 데이터 저장소로 사용할 때 필요한 인증·CRUD 보일러플레이트를 제거해주는 경량 클라이언트입니다.
서비스 계정 인증, 행 추가/조회/수정, 전화번호 셀 포맷 처리를 포함합니다.

설치

npm install @moonhr/sheets-client

사전 준비

  1. Google Cloud Console에서 서비스 계정을 생성하고 JSON 키를 발급합니다.
  2. 해당 서비스 계정 이메일을 대상 스프레드시트에 편집자 권한으로 공유합니다.
  3. 환경변수를 설정합니다.
GOOGLE_SERVICE_ACCOUNT_KEY={"client_email":"...","private_key":"..."}
GOOGLE_SHEETS_SPREADSHEET_ID=1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgVE2upms
GOOGLE_SHEETS_SHEET_NAME=Sheet1

기본 사용법

import { createSheetsClient } from '@moonhr/sheets-client'

const client = createSheetsClient({
  serviceAccountKey: process.env.GOOGLE_SERVICE_ACCOUNT_KEY,
  spreadsheetId: process.env.GOOGLE_SHEETS_SPREADSHEET_ID,
  sheetName: process.env.GOOGLE_SHEETS_SHEET_NAME,
})

API

appendRow(values, range?)

시트 마지막 행에 데이터를 추가합니다.

await client.appendRow(['2024-01-01', '홍길동', '회사명', '01012345678'])

| 파라미터 | 타입 | 기본값 | 설명 | |---|---|---|---| | values | string[] | — | 셀 값 배열 | | range | string | 'A:Z' | 추가 범위 |


getRows(range?)

지정 범위의 모든 행을 반환합니다. 각 셀은 trim된 문자열입니다.

const rows = await client.getRows('A:E')
// [['헤더1', '헤더2', ...], ['값1', '값2', ...], ...]

findRow(matcher, options?)

조건에 맞는 첫 번째 행을 반환합니다. 없으면 null.

컬럼 인덱스로 매칭 (0-based)

const result = await client.findRow({ 1: '홍길동', 2: '회사명' })

양쪽 trim + 소문자 비교를 수행합니다.

커스텀 함수로 매칭

전화번호처럼 숫자 비교가 필요한 경우에 사용합니다.

import { digitsOnly } from '@moonhr/sheets-client'

const result = await client.findRow((row) => {
  return row[1].trim().toLowerCase() === '홍길동' &&
         digitsOnly(row[3]) === digitsOnly('010-1234-5678')
})

반환값

{
  rowIndex: number   // 시트 행 번호 (1-based) — updateRow에 그대로 사용
  values: string[]   // 해당 행의 셀 값 배열
}

options

| 옵션 | 타입 | 기본값 | 설명 | |---|---|---|---| | range | string | 'A:Z' | 검색 범위 | | skipHeader | boolean | true | 첫 번째 행(헤더) 건너뜀 여부 |


updateRow(rowIndex, values, startCol?)

특정 행의 셀을 업데이트합니다.

// findRow가 반환한 rowIndex를 그대로 사용
await client.updateRow(result.rowIndex, ['홍길동', '새회사', '01099998888'], 'B')
// → B{rowIndex}:D{rowIndex} 범위를 업데이트

| 파라미터 | 타입 | 기본값 | 설명 | |---|---|---|---| | rowIndex | number | — | 시트 행 번호 (2 이상) | | values | string[] | — | 교체할 셀 값 배열 | | startCol | string | 'A' | 시작 열 문자 |


유틸리티

import { toTextCell, digitsOnly, stripQuotes } from '@moonhr/sheets-client'

| 함수 | 설명 | 예시 | |---|---|---| | toTextCell(value) | 전화번호를 시트에 텍스트로 강제 저장 (숫자 자동변환 방지) | '01012345678'"'01012345678" | | digitsOnly(value) | 숫자만 추출 (전화번호 비교용) | '010-1234-5678''01012345678' | | stripQuotes(value) | 환경변수 래핑 따옴표 제거 | '"Sheet1"''Sheet1' |

실사용 예시 — RSVP 폼

  await client.updateRow(
    found.rowIndex,
    ['홍길동', '새회사', toTextCell('01099998888'), '[email protected]'],
    'B'
  )
}
