UNPKG：npm 包文件 CDN 与元数据 API

UNPKG 官方首页定义按包名、版本和文件路径访问 npm 镜像的 HTTPS CDN，并提供 ?meta 返回文件路径、大小、类型与完整性值。无版本会解析 latest 并重定向；认证、托管费用和配额未说明，仅文档整理。

Source statements below remain in their published language. Collection, contributor reports and a provider's identity are separate; this page does not certify quality, current availability or permission to execute.

Published description

UNPKG 将 npm 包文件通过 CDN 提供给浏览器或 HTTP 客户端，可列目录、解析包入口或读取目录元数据。本卡选用只读 JSON 元数据 URL，不运行页面中的脚本、加载依赖或安装包；UNPKG 明确不是 npm 官方关联服务。

Inputs

URL 格式 https://unpkg.com/{package}@{version}/{file}；版本可为完整版本、npm dist-tag 或 semver 范围，省略默认为 latest。
目录 URL 末尾加 / 可列文件；包根/子目录附 ?meta 返回 JSON。
普通文件省略时按 main/exports 默认条件解析；?conditions 指定自定义 export 条件。

Outputs

?meta 返回 package、version、prefix 与 files 数组，文件含 path、size、type、integrity。
普通文件路径返回包文件内容，目录返回 listing；未完全解析的版本 URL 会重定向为版本固定的永久地址。
esm.unpkg.com 另可转换浏览器模块，不能把其构建/元数据选项与基础 CDN ?meta 混用。

Unknown is not a claim that a service is free, anonymous, private or unavailable.

Limitations

latest/tag/范围依赖解析，结果可随新版本变化；完整固定版本与路径更利于重现和缓存。
托管 npm 文件不代表其可安全执行或免许可义务，包版权/许可需逐包核对。
UNPKG 是独立开源项目，不附属于或受 npm 支持；不能与 npm Registry 身份混同。
主页未给认证、请求速率、配额、费用或 SLA；Shield Beta 的宣传不是本次安全验证。

Unknowns

托管认证要求、价格、限流、配额、SLA、请求日志保留未知。
目标包的许可、文件安全性、实际完整性与实时可用性未验证。

Fixed profiles, conditions and evidence

Read state: not_checked; review state: unknown. Do not combine different profiles.

资料与来源声明不等于本站实测；未列出的条件仍未知。

结构化配方只按公开声明检查约束与接口，不执行任务或授予权限；缺失记录保持未知，接口兼容不证明实际成功。
