# Turborepo — Rust Build System for JS Monorepos

> Turborepo speeds JavaScript and TypeScript monorepos with task graphs, caching, and remote cache support. Use `turbo run` to standardize builds.

## Install

Save as a script file and run:

## Quick Use

1. Install the verified package or repo entrypoint:

```bash
npm install --save-dev turbo
```

2. Run the first local check:

```bash
npx turbo run build test lint
```

3. Add a repeatable verification command:

```bash
npx turbo run build test lint --cache-dir=.turbo
```

---

## Intro

Turborepo is a verified GitHub-backed tool for modern AI and developer workflows, sourced from `vercel/turborepo` with 30,369 stars and a MIT license snapshot. Best for: JS and TS monorepos where repeated lint, test, and build tasks waste time across packages and CI jobs. Works with: package managers, turbo.json, Next.js, pnpm/npm/yarn workspaces, Vercel Remote Cache. Setup time: 10 minutes. Use it when you need a concrete, repeatable path rather than another one-off shell snippet.

## Operating Pattern

### Fit check

| Question | Practical answer |
|---|---|
| What do you install? | `turbo` from `vercel/turborepo` |
| What is the first command? | `npx turbo run build test lint` |
| What proves it works? | `npx turbo run build test lint --cache-dir=.turbo` |
| How long should a pilot take? | 10 minutes for a small repo or sandbox |

### Adoption loop

1. Run the tool on a disposable branch or sandbox project.
2. Capture before/after output so reviewers can see the exact effect.
3. Add the smallest CI or local check that prevents regressions.
4. Document owner, upgrade command, and rollback command in the repo.

### Recommended use

Declare task dependencies in `turbo.json`, then make every package expose the same script names. The cache only pays off when task boundaries are stable.

### Guardrails

Do not hide flaky tests behind caching. Reproduce a clean no-cache CI run before trusting remote cache results.

### Rollout checklist

- Pin the package or release version before using it in CI.
- Keep credentials in environment variables or the platform secret store.
- Add one owner who is responsible for upgrades and breaking-change triage.
- Re-check the GitHub repo before writing docs that mention APIs or install paths.

### FAQ

**Q: Is this production-ready?**
A: The repo exists at `https://github.com/vercel/turborepo` and has 30,369 GitHub stars. Treat the first rollout as a controlled pilot until your team has tested install, rollback, and CI behavior.

**Q: Why use it instead of a generic script?**
A: The value is repeatability: a named package, a documented command, a source repo, and a small verification path that can be reviewed by teammates.

**Q: What should I measure first?**
A: Measure setup time against the 10 minutes target, count how many files or tasks it changes, and record whether the CI command catches the same issue locally.

## 快速使用

1. 安装已验证的包或仓库入口：

```bash
npm install --save-dev turbo
```

2. 跑第一次本地检查：

```bash
npx turbo run build test lint
```

3. 加一个可重复验证命令：

```bash
npx turbo run build test lint --cache-dir=.turbo
```

## 简介

Turborepo 是一个已通过 GitHub 仓库验证的现代 AI / 开发者工具，来源 `vercel/turborepo`，当前星标快照 30,369，许可证 MIT。适合：多个 package 的 lint、test、build 在本地和 CI 重复浪费时间的 JS / TS monorepo。兼容：package manager、turbo.json、Next.js、pnpm/npm/yarn workspace、Vercel Remote Cache。装机时间：10 minutes。当你需要的是可重复落地路径，而不是一次性 shell 片段时，用它。

## 操作模式

### 适配检查

| 问题 | 实用答案 |
|---|---|
| 安装什么？ | 来自 `vercel/turborepo` 的 `turbo` |
| 第一条命令？ | `npx turbo run build test lint` |
| 如何证明可用？ | `npx turbo run build test lint --cache-dir=.turbo` |
| 小范围试点多久？ | 小仓库或 sandbox 约 10 minutes |

### 接入循环

1. 先在一次性分支或 sandbox 项目里跑。
2. 记录 before / after 输出，让 reviewer 看见实际影响。
3. 加最小的 CI 或本地检查，防止同类问题回归。
4. 在仓库文档里写清 owner、升级命令和回滚命令。

### 推荐用法

在 `turbo.json` 里声明任务依赖，然后让每个 package 暴露一致脚本名。只有任务边界稳定，缓存才真正有收益。

### 风险边界

不要用缓存掩盖 flaky tests。信任远程缓存前，先复现一次干净的 no-cache CI。

### 推广检查表

- 进入 CI 前固定包版本或 release 版本。
- 凭据放进环境变量或平台 secret store。
- 指定一个 owner 负责升级和 breaking change 分流。
- 文档里写 API 或安装路径前，重新核验 GitHub 仓库。

### FAQ

**Q: 能直接上生产吗？**
A: 仓库已验证存在：`https://github.com/vercel/turborepo`，GitHub 星标 30,369。第一次上线仍建议控制试点，先验证安装、回滚和 CI 行为。

**Q: 为什么不用普通脚本？**
A: 价值在可重复：有命名包、文档化命令、源仓库和可被团队 review 的最小验证路径。

**Q: 第一步应该量什么？**
A: 先量装机时间是否接近 10 minutes，它改了多少文件或任务，以及 CI 命令是否能在本地抓到同类问题。
