Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

DSH plugin: query package metadata from the npm and PyPI registries (pkg_info).

Readme

dsh-pkg-info

DSH 包信息查询工具插件。注册一个 pkg_info 工具,查询 npmPyPI 两个 registry 的包元数据,把结果规范化为一个结构化 JSON 对象,供模型与 Code Mode 程序化调用。零依赖、纯 ESM、无构建

简介

  • 工具名:pkg_info
  • 能力:查询 npm 包(registry.npmjs.org)与 PyPI 包(pypi.org)的名称、版本、描述、许可证、作者、主页、仓库、版本数、依赖等信息。
  • 行为:永不抛异常。404、网络错误、超时、JSON 解析失败都折叠为 { ok: false, error: { stage, message?, status? } };成功返回 { ok: true, registry, name, version, ... }

安装

dsh plugin --profile <name> add file:./plugins/dsh-pkg-info
# 或发布后:
dsh plugin --profile <name> add dsh-pkg-info

参数

| 参数 | 类型 | 必填 | 默认 | 说明 | |---|---|---|---|---| | registry | enum | — | npm | npm / pypi,选择要查询的 registry | | name | string | ✅ | — | 包名。npm 作用域包写 @scope/name;PyPI 项目名大小写不敏感 | | version | string | — | latest | 指定版本(npm 也支持 dist-tag 如 latest/next);缺省查最新版 |

返回字段

npm(registry: "npm"

| 字段 | 类型 | 说明 | |---|---|---| | ok / registry / name / version | boolean/string | 状态、registry、规范包名、解析到的版本 | | description | string | null | 包描述 | | license | string | null | SPDX 许可证(对象/数组会被规范成字符串) | | author | string | null | 作者,规范为 "name <email>" | | homepage | string | null | 主页 URL | | repository | string | null | 仓库 URL | | distTags | object | dist-tags 映射(如 { latest: "2.7.0", ... }) | | created / modified | string | null | time 字段的创建/修改时间(ISO 8601) | | versionsCount | integer | 已发布版本数 | | dependencies | object | null | 该版本的 dependencies | | peerDependencies | object | null | 该版本的 peerDependencies |

PyPI(registry: "pypi"

| 字段 | 类型 | 说明 | |---|---|---| | ok / registry / name / version | boolean/string | 状态、registry、规范项目名、解析到的版本 | | summary | string | null | 项目摘要(info.summary) | | license | string | null | 许可证(info.license,空串归一为 null) | | author | string | null | 作者(info.author) | | home_page | string | null | 主页 URL(info.home_page) | | releasesCount | integer | 发布版本数(releases 键数) | | requiresDist | string[] | null | 该版本的 requires_dist 依赖列表 |

失败(ok: false

{ ok: false, registry, name, error: { stage: 'http'|'request'|'parse', message?, status? } }

  • 404:{ stage: 'http', status: 404 }
  • 网络/超时(10s):{ stage: 'request', message }
  • JSON 解析失败:{ stage: 'parse', message }

示例

// 查 npm 最新版
{ "registry": "npm", "name": "yaml" }
// 查 npm 指定版本
{ "registry": "npm", "name": "yaml", "version": "2.5.0" }
// 查 PyPI 最新版
{ "registry": "pypi", "name": "requests" }
// 查 PyPI 指定版本
{ "registry": "pypi", "name": "requests", "version": "2.28.1" }
