Bun

### [阅读文档 →](https://bun.com/docs) ## 什么是 Bun？ Bun 是一个用于 JavaScript 和 TypeScript 应用的多合一工具包。它以名为 `bun` 的单一可执行文件形式发布。 其核心是 _Bun 运行时_，这是一个快速的 JavaScript 运行时，旨在作为 **Node.js 的直接替代品**。它使用 Zig 编写，底层由 JavaScriptCore 提供支持，从而大幅缩短了启动时间并降低了内存使用量。 ``` bun run index.tsx # TS and JSX supported out-of-the-box ``` `bun` 命令行工具还实现了测试运行器、脚本运行器和兼容 Node.js 的包管理器。在开发中，你不再需要 1,000 个 node_modules，只需要 `bun`。Bun 的内置工具比现有选项快得多，并且可以在现有的 Node.js 项目中直接使用，几乎或完全不需要修改。 ``` bun test # run tests bun run start # run the `start` script in `package.json` bun install # install a package bunx cowsay 'Hello, world!' # execute a package ``` ## 安装 Bun 支持 Linux (x64 & arm64)、macOS (x64 & Apple Silicon) 和 Windows (x64 & arm64)。 ``` # 使用 install script（推荐） curl -fsSL https://bun.com/install | bash # 在 windows 上 powershell -c "irm bun.sh/install.ps1 | iex" # 使用 npm npm install -g bun # 使用 Homebrew brew tap oven-sh/bun brew install bun # 使用 Docker docker pull oven/bun docker run --rm --init --ulimit memlock=-1:-1 oven/bun ``` ### 升级 要升级到最新版本的 Bun，请运行： ``` bun upgrade ``` Bun 会在每次向 `main` 分支提交代码时自动发布一个 canary 版本。要升级到最新的 canary 版本，请运行： ``` bun upgrade --canary ``` [查看 canary 版本](https://github.com/oven-sh/bun/releases/tag/canary) ## 快速链接 -
