我发现我经常对https://www.npmjs.com/上的搜索顺序和表现力不满意。我想应该有一种方法可以使用https://api.npmjs.org/或http://registry.npmjs.org/以编程方式查询服务器。但是怎么样？文件在哪里？
（或者是否有节点包来促进这一点？我知道SO不是关于工具或包装推荐的，所以也许我也不应该问这个问题，但如果有一些工具，我可能也可以从中读取API。）
答案 0 :(得分：19)
当然，至少有一个工具可以与该注册表进行通信，这就是npm命令行工具本身。例如，它的search首先更新索引的本地缓存副本，然后对其进行过滤。在update-index中，可以看到以/-/all结尾的网址显然是特殊的。事实上，将其附加到registry.npmjs.org（故意不格式化为链接）将获取125M文件，这可能对您的浏览器来说太多了。幸运的是，缓存版本存储在~/.npm/registry.npmjs.org/-/all/.cache.json中。从那里可以读取所有已知包的列表。然后，可以继续更详细地查询每个这样的包。
npm search显然没有使用更复杂的方案这一事实表明这里没有太多的服务器端api。
在网页上搜索提到api.npmjs.org的网页时，我发现可以从那里检索download counts。我找到的所有其他文件都使用了这一单一设施。
寻找替代方案，我偶然发现npmsearch.com提供了一些更多功能的搜索工具，并a somewhat documented API。
答案 1 :(得分：12)
您始终可以使用NPM注册表客户端：https://github.com/npm/npm-registry-client。
如果仔细观察，可以获得API的端点。 例如，为了得到包的dist-tag，你可以去/ - / package / packageName / dist-tags'
因此，要获得babel-core dist标记，您需要转到http://registry.npmjs.org/-/package/babel-core/dist-tags
答案 2 :(得分：11)
最近发现了一个非常好的npm查询网站https://npms.io。 他们还根据各种数据为每个包装提供质量点系统。
他们还将使用收集的有关项目的信息为每个包提供评分系统。最终得分是根据质量，维护，受欢迎程度和个性的四个不同方面计算的。
API文档：https://api-docs.npms.io

https://skimdb.npmjs.com/registry/_all_docs
这是拉取所有包名的当前方法。
网址搜索为http://registry.npmjs.com/-/v1/search?text=<searchstring>&size=20

看看sinopia注册表界面：https://github.com/rlidwka/sinopia/blob/master/lib/index-api.js。 npm客户端的默认注册表是https://registry.npmjs.org（在控制台上试用：npm config ls -l）。因此，您可以尝试以下（引用sinopia API）来获取有关react 15.0.2的数据
答案 5 :(得分：3)
我知道这个答案很旧，但是有些人仍然可以找到它的相关性，
经过大量搜索，我终于找到了一些东西，该解决方案不使用NPM API，因为它的文档不好，而且有很多缺点
（这对搜索以外的其他用途很有帮助，例如搜索流行的软件包列表（我需要））
解决方案是使用Libraries.io
Libraries.io为来自36个程序包管理器的4,273,741个程序包中的数据建立索引。 （包括NPM） 来自Libraries.io page
它具有出色的API和良好的文档，还提供了几种语言的API包装器
您可以看一下使用该库here的CLI程序
答案 6 :(得分：3)
您可以在以下GitHub存储库中找到官方NPM注册表API的官方文档：https://github.com/npm/registry
搜索端点的文档可以在这里找到：https://github.com/npm/registry/blob/master/docs/REGISTRY-API.md#get-v1search
可接受以下查询参数：文本，大小，质量，受欢迎程度，维护
curl -sL 'https://registry.npmjs.org/-/v1/search?text=react-native&size=5' | jq
在这里，我们使用curl发出API请求，并使用jq格式化JSON响应。返回以下输出：

答案 7 :(得分：2)
如果找不到软件包，或者只是一起破解shell脚本，则注册表Registry API Docs中的git repository包含有关Search API和搜索限定符的详细信息。
如果要在公共注册表中查找最流行的不安全软件包，请运行：
wget -qO - "http://registry.npmjs.com/-/v1/search?text=is:insecure&popularity=1.0&size=1"
上面的代码使用is:insecure搜索限定符，没有任何其他文本条件，并在size=1（最受欢迎的位置）中获取popularity=1.0的结果。
