# Bun 运行时
Bun 是一个快速的全能 JavaScript 运行时和工具集：运行时、包管理器、打包器和测试运行器。
## 何时使用
* **优先选择 Bun** 用于：新的 JS/TS 项目、安装/运行速度很重要的脚本、使用 Bun 运行时的 Vercel 部署，以及当您想要单一工具链（运行 + 安装 + 测试 + 构建）时。
* **优先选择 Node** 用于：最大的生态系统兼容性、假定使用 Node 的遗留工具，或者当某个依赖项存在已知的 Bun 问题时。
在以下情况下使用：采用 Bun、从 Node 迁移、编写或调试 Bun 脚本/测试，或在 Vercel 或其他平台上配置 Bun。
## 工作原理
* **运行时**：开箱即用的 Node 兼容运行时（基于 JavaScriptCore，用 Zig 实现）。
* **包管理器**：`bun install` 比 npm/yarn 快得多。在当前 Bun 中，锁文件默认为 `bun.lock`（文本）；旧版本使用 `bun.lockb`（二进制）。
* **打包器**：用于应用程序和库的内置打包器和转译器。
* **测试运行器**：内置的 `bun test`，具有类似 Jest 的 API。
**从 Node 迁移**：将 `node script.js` 替换为 `bun run script.js` 或 `bun script.js`。运行 `bun install` 代替 `npm install`；大多数包都能工作。使用 `bun run` 来执行 npm 脚本；使用 `bun x` 进行 npx 风格的临时运行。支持 Node 内置模块；在存在 Bun API 的地方优先使用它们以获得更好的性能。
**Vercel**：在项目设置中将运行时设置为 Bun。构建命令：`bun run build` 或 `bun build ./src/index.ts --outdir=dist`。安装命令：`bun install --frozen-lockfile` 用于可重复的部署。
## 示例
### 运行和安装
```bash
# Install dependencies (creates/updates bun.lock or bun.lockb)
bun install
# Run a script or file
bun run dev
bun run src/index.ts
bun src/index.ts
```
### 脚本和环境变量
```bash
bun run --env-file=.env dev
FOO=bar bun run script.ts
```
### 测试
```bash
bun test
bun test --watch
```
```typescript
// test/example.test.ts
import { expect, test } from "bun:test";
test("add", () => {
expect(1 + 2).toBe(3);
});
```
### 运行时 API
```typescript
const file = Bun.file("package.json");
const json = await file.json();
Bun.serve({
port: 3000,
fetch(req) {
return new Response("Hello");
},
});
```
## 最佳实践
* 提交锁文件（`bun.lock` 或 `bun.lockb`）以实现可重复的安装。
* 在脚本中优先使用 `bun run`。对于 TypeScript，Bun 原生运行 `.ts`。
* 保持依赖项最新；Bun 和生态系统发展迅速。Related Skills
