Scripts

매 한 줄

"매 scripts는 package.json 의 entry point 인 명령어 alias". npm run <name> 으로 실행되며, dev/build/test/lint/deploy 등의 lifecycle automation 을 정의. 2026 기준 npm/pnpm/bun/yarn 호환, 매 monorepo 에서는 turbo/nx 가 orchestration.

매 핵심

매 lifecycle

• pre/post: prebuild → build → postbuild 자동 실행
• special names: start, test, install, prepare
• arbitrary: 매 다른 이름 은 npm run <name>

매 cross-platform

• cross-env, rimraf, mkdirp 등으로 OS 차이 흡수
• 매 modern 대안: zx, execa, tsx-based scripts

매 응용

1. Local dev: dev, build, test, lint.
2. CI: ci:test, ci:build, ci:deploy.
3. Tooling: typecheck, format, analyze.
4. Release: release, publish:dry.

💻 패턴

Modern package.json scripts

{
  "scripts": {
    "dev": "next dev --turbo",
    "build": "next build",
    "start": "next start",
    "lint": "biome check .",
    "lint:fix": "biome check --write .",
    "typecheck": "tsc --noEmit",
    "test": "vitest",
    "test:e2e": "playwright test",
    "test:coverage": "vitest run --coverage",
    "format": "biome format --write .",
    "clean": "rimraf .next dist coverage",
    "prepare": "husky",
    "release": "changeset publish"
  }
}

Pre/post hooks

{
  "scripts": {
    "prebuild": "npm run typecheck && npm run lint",
    "build": "tsc -p tsconfig.build.json",
    "postbuild": "node scripts/copy-assets.mjs"
  }
}

Composing with npm-run-all or concurrently

{
  "scripts": {
    "dev": "concurrently -n web,api -c blue,green \"npm:dev:web\" \"npm:dev:api\"",
    "dev:web": "next dev",
    "dev:api": "tsx watch server/index.ts",
    "verify": "run-p typecheck lint test"
  }
}

TypeScript script with tsx

// scripts/seed.ts
import { db } from "../src/lib/db";
import { users } from "../src/lib/db/schema";

await db.insert(users).values([
  { email: "alice@example.com" },
  { email: "bob@example.com" },
]);
console.log("매 seed complete");

{ "scripts": { "db:seed": "tsx scripts/seed.ts" } }

zx automation

#!/usr/bin/env zx
import "zx/globals";

const branches = (await $`git branch --merged main`).stdout
  .split("\n")
  .map((b) => b.trim())
  .filter((b) => b && !b.startsWith("*") && b !== "main");

for (const b of branches) {
  await $`git branch -d ${b}`;
}
echo`매 deleted ${branches.length} merged branches`;

Cross-platform env

{
  "scripts": {
    "build:prod": "cross-env NODE_ENV=production webpack",
    "test:debug": "cross-env DEBUG=app:* vitest"
  }
}

Monorepo with pnpm + turbo

// root package.json
{
  "scripts": {
    "build": "turbo run build",
    "dev": "turbo run dev --parallel",
    "test": "turbo run test --filter=...[origin/main]"
  }
}

Bun-native scripts (faster startup)

{
  "scripts": {
    "dev": "bun --hot src/index.ts",
    "test": "bun test",
    "build": "bun build src/index.ts --outdir dist --target node"
  }
}

CI matrix script

{
  "scripts": {
    "ci:lint": "biome ci .",
    "ci:typecheck": "tsc --noEmit",
    "ci:test": "vitest run --coverage --reporter=verbose",
    "ci:build": "next build",
    "ci": "run-s ci:lint ci:typecheck ci:test ci:build"
  }
}

매 결정 기준

상황	Approach
매 simple alias	npm script directly
매 multi-step orchestration	npm-run-all / concurrently
Complex shell scripting	zx / bash file
TS logic	tsx / bun + TS file
Monorepo	turbo / nx

기본값: npm scripts + tsx for TS + concurrently for parallel. 매 monorepo 면 turbo.

🔗 Graph

• 부모: Node.js
• 변형: Task · Turbo · Nx
• 응용: Husky Git Hooks
• Adjacent: tsx · bun

🤖 LLM 활용

언제: package.json 의 standard automation, dev/build/test/lint pipeline. 언제 X: 매 100+ lines of bash logic — 매 standalone script file 로 추출.

❌ 안티패턴

• Inline complex shell: && if [[ ... ]]; then ... fi in JSON → 매 unreadable. zx / bash file.
• No clean script: 매 stale build artifact debug 어려움. clean 필수.
• OS-specific commands: rm -rf Windows 실패 → cross-platform 도구.
• Hidden side effects in postinstall: 매 supply-chain risk. 신중.
• Duplicate scripts across packages: 매 monorepo 면 turbo / shared config.

🧪 검증 / 중복

• Verified (npm docs, package.json spec).
• 신뢰도 A.
