＃为什么jsDelivr？
性能和运行时间导向我们的公共CDN是建立在考虑性能和可靠性。一切都进行了优化，并不断完善，提供所有用户的最大速度和正常运行时间。性能始终处于监控，并且我们一直在寻找新的技术和服务提供者，可能会进一步提高我们的CDN。
停机时间，超时或慢的反应是完全不能接受的。这个想法是不是简单地提供一个公共的CDN，而是要提供最好的体验和坚如磐石的产品。
多CDN不同于竞争，jsDelivr使用多个CDN提供商，造成可能的最佳运行时间和性能。我们目前使用[MaxCDN] 7，[CloudFlare的] 8和[KeyCDN] 14。
上的CDN提供商的顶部，jsDelivr还利用在位置定制的服务器，其中的CDN不必存在的点，以进一步优化的文件下载速度为邻近这些位置的用户。
如果一个CDN或自定义服务器出现故障，使用jsDelivr网站不会有任何问题，因为所有的流量将被立即重定向到剩余的运营商。
智能负载平衡jsDelivr使用[Cedexis] 10与实际用户的性能数据（也称为RUM）作出路由决定。这些指标是从数百个网站收集和使用我们的负载均衡算法，使为服务内容的准确的决策。
所有的供应商（的CDN和自定义服务器）是由真正的用户来自世界各地的测试，每天数百万次。基于该信息，jsDelivr知道提供商是最快的为每个用户。每个用户得到基于他或她的位置，ISP和提供者的实时运行时间的唯一响应。
该系统也立即响应性能下降和供应商的停机时间。如果CDN是一个DDoS攻击下，其业绩下降在一些地方，在几秒钟的事算法将拿起变化，并开始服务于不同的供应商，所有受影响的用户。
SPDY我们所有的持久性有机污染物的支持[SPDY（https://developers.google.com/speed/spdy/）装载，使高性能的传输时可能。
＃【如何提交或更新项目（https://github.com/jsdelivr/jsdelivr/blob/master/CONTRIBUTING.md） 请参阅[CONTRIBUTING.md]（https://github.com/jsdelivr/jsdelivr/blob/master/CONTRIBUTING.md）有关如何将新的项目添加到jsDelivr说明。
自动更新jsDelivr可以自动保持一个项目最多，最新的新版本发布。 配置过程简单快捷：您只需启用此功能的项目 是随着info.ini建立在其根目录中的update.json文件。
＃＃＃＃＃ 例(/files/humane.js/update.json):

＃ 用法
URL结构典型应用： //cdn.jsdelivr.net/{projectName} / {版本} / {文件} 例如：//cdn.jsdelivr.net / jQuery/1.11.0/ jquery.min.js
如果你想在该版本文件夹作为一个压缩包中的所有文件： //cdn.jsdelivr.net/{projectName} / {version)} / {} PROJECTNAME .zip
从他们的最新版本作为一个单一的分页文件下载的三个项目\'mainfile： //cdn.jsdelivr.net/g/{projectName}，{项目名称}，{项目名称}
您可以指定每个文件的特定版本或版本分支： //cdn.jsdelivr.net/g/{projectName} @ {版本}，{} PROJECTNAME @ {versionAlias}，{项目名称}
您也可以从项目中（通常用于插件附带项目）选择多个文件： //cdn.jsdelivr.net/g/{projectName}@{version}({filepath1}+{filepath2}),{projectName}@{versionAlias},{projectName}
版本走样对于最新版本的使用：
//cdn.jsdelivr.net/ {}项目名称/最新/ {文件}
您也可以加载每个分支最新版本：
//cdn.jsdelivr.net/ {} PROJECTNAME {/3.8/{file}最新的3.8分支
//cdn.jsdelivr.net/ {} PROJECTNAME / 3 / {file}最新的3支
自动加载的项目使用的主要文件：
//cdn.jsdelivr.net/{projectName} / latest/ mainfile
根据项目的配置在\'info.ini与正确的MIME HTTP标头，jsDelivr将自动加载主文件。如果没有指定mainfile`参数，请求将导致404错误。
装载有一个HTTP请求多个文件使用加载主文件的最新版本的多个项目：
//cdn.jsdelivr.net /g/ abaaso,ace,alloyui
主文件abaaso和用于其他项目的主文件的最新版本的负载3.8.15版：
//cdn.jsdelivr.net /g/abaaso@3.8.15,ace,alloyui
加载主文件的最新版本的所有文件和abaaso载荷版本分支3.8（例如版本16年8月3日：
//cdn.jsdelivr.net / G / abaaso@3.8.15.ace.alloyui
将多个文件，输入您要加载括号内（）由加+符号分隔的所有文件中的相对路径。支架可被编码为28％和29％无问题。
加载多个项目中的多个文件：
//cdn.jsdelivr.net/g/jquery@2.1.0,angularjs@1.2.14(angular.min.js+angular-resource.min.js+angular-animate.min.js+angular-cookies.min.js+angular-route.min.js+angular-sanitize.min.js)
与往常一样，它支持版本的别名和最新版本：
//cdn.jsdelivr.net/g/jquery,angularjs@1.2(angular.min.js+angular-resource.min.js+angular-animate.min.js+angular-cookies.min.js+angular-route.min.js+angular-sanitize.min.js)
//cdn.jsdelivr.net/g/jquery,angularjs(angular.min.js+angular-resource.min.js+angular-animate.min.js+angular-cookies.min.js+angular-route.min.js+angular-sanitize.min.js)
文/ css头：现在，如果组合中的所有文件都有一个\'.css扩展，则服务器将自动与Content-Type的回应。在其他情况下，服务器响应\'内容类型：应用程序/ javascript头。
//cdn.jsdelivr.net/g/angularui@0.4.0（角ui.min.css），animatecss @ 3.2.0
第一3-4请求将比较慢，因为它们没有被缓存。随后，这些动态文件获取缓存并成为静态文件（同所有其他）。

We offer a stable CDN that can be used in production even on popular websites with huge amounts of traffic. There are no bandwidth limits or premium features and its completely free to use by anybody. All kinds of files are allowed, including JavaScript libraries, jQuery plugins, CSS frameworks, fonts and more. You can use this repo to make your own changes and improve the contents of jsDelivr\'s CDN. Feel free to open issues and pull requests if you think something should be changed. All changes made to this repo are synced to the CDN. It can take a few minutes for the changes to appear on the website. [jsDelivr – The advanced open source public CDN][11] [How jsDelivr works (outdated)][4] [Compare public CDNs][5] [jsDelivr community chat][12] # Why jsDelivr? Performance and Uptime Oriented -------------------- Our public CDN is built with performance and reliability in mind. Everything is optimized and being constantly improved to offer all users maximum speed and uptime. Performance is monitored at all times, and we are always looking into new technologies and providers that may further improve our CDN. Downtime, timeouts or slow responses are simply unacceptable. The idea is not to simply offer a public CDN, but to offer the best possible experience and a rock-solid product. Multi-CDN --------- Unlike the competition, jsDelivr uses multiple CDN providers, resulting in the best possible uptime and performance. We currently use [MaxCDN][7], [CloudFlare][8], and [KeyCDN][14]. On top of CDN providers, jsDelivr also utilizes custom servers in locations where CDNs don\'t have points of presence to further optimize the speed of file downloads for users near those locations. If a CDN or custom server goes down, websites that use jsDelivr won\'t have any issues because all traffic will be instantly redirected to remaining operational providers. Smart Load Balancing -------------------- jsDelivr uses [Cedexis][10] with real user performance data (also known as RUM) to make its routing decisions. These metrics are gathered from hundreds of websites and are used in our load balancing algorithm to make accurate decisions for serving content. All providers (CDNs and custom servers) are tested millions times per day by real users from all over the world. Based on this information, jsDelivr knows what provider is the fastest for each user. Each user gets a unique response based on his or her location, ISP, and the providers\' uptime in real time. This system also responds immediately to performance degradation and downtime of providers. If a CDN is under a DDoS attack, and their performance drops in some locations, in matter of seconds the algorithm will pick up the change and start serving a different provider to all affected users. SPDY ----------------- All of our POPs support [SPDY](https://developers.google.com/speed/spdy/) loading, allowing performant transfers when possible. # [How to submit or update projects](https://github.com/jsdelivr/jsdelivr/blob/master/CONTRIBUTING.md) Refer to [CONTRIBUTING.md](https://github.com/jsdelivr/jsdelivr/blob/master/CONTRIBUTING.md) for instructions on how to add a new project to jsDelivr. Auto-Updating ------------- jsDelivr can automatically keep a project up-to-date as new versions are released. Configuration is fast and easy: All you need to enable this feature for a project is to create an `update.json` file in its root directory along with the `info.ini`. ##### Example ([*/files/humane.js/update.json*](https://github.com/jsdelivr/jsdelivr/blob/master/files/humane.js/update.json)): ```json { \"packageManager\": \"github\", \"name\": \"humane.js\", \"repo\": \"wavded/humane-js\", \"files\": { \"include\": [\"humane.min.js\", \"humane.js\", \"./themes/**/*\"] } } Full documentation is available here.
Usage URL StructureTypical usage:
//cdn.jsdelivr.net/{projectName}/{version}/{file}
Example: //cdn.jsdelivr.net/jquery/1.11.0/jquery.min.js
When you want all the files in that version folder as a single compressed archive:
//cdn.jsdelivr.net/{projectName}/{version}/{projectName}.zip
Downloads the three projects\' mainfile from their latest versions as a single collated file:
//cdn.jsdelivr.net/g/{projectName},{projectName},{projectName}
You may specify a specific version or version-branch per file:
//cdn.jsdelivr.net/g/{projectName}@{version},{projectName}@{versionAlias},{projectName}
You may also select more than one file from a project (typically for plug-ins that ship with the project):
//cdn.jsdelivr.net/g/{projectName}@{version}({filepath1}+{filepath2}),{projectName}@{versionAlias},{projectName}
For latest version use:
//cdn.jsdelivr.net/{projectName}/latest/{file}
You can also load latest versions per branch:
//cdn.jsdelivr.net/{projectName}/3.8/{file} Latest in 3.8 branch
//cdn.jsdelivr.net/{projectName}/3/{file} Latest in 3 branch
To automatically load the main file of a project use:
//cdn.jsdelivr.net/{projectName}/{version}/mainfile
Depending on the project, jsDelivr will automatically load the main file as configured in info.ini with correct MIME HTTP headers. If no mainfile parameter was specified, the request will result in 404 error.
Load multiple files with single HTTP requestLoad multiple projects using the lastest version of the main file:
//cdn.jsdelivr.net/g/abaaso,ace,alloyui
Load version 3.8.15 of the main file for abaaso and the latest version of the main file for the other projects:
//cdn.jsdelivr.net/g/abaaso@3.8.15,ace,alloyui
Load the latest version of the main file for all files and for abaaso loads version branch 3.8 (e.g. version 3.8.16):
//cdn.jsdelivr.net/g/abaaso@3.8,ace,alloyui
To combine multiple files enter the relative paths to all files you want to load inside brackets () separated by a plus + symbol. Brackets can be encoded as %28 and %29 without issues.
Load multiple files from multiple projects:
//cdn.jsdelivr.net/g/jquery@2.1.0,angularjs@1.2.14(angular.min.js+angular-resource.min.js+angular-animate.min.js+angular-cookies.min.js+angular-route.min.js+angular-sanitize.min.js)
As always it supports version aliasing and latest versions:
//cdn.jsdelivr.net/g/jquery,angularjs@1.2(angular.min.js+angular-resource.min.js+angular-animate.min.js+angular-cookies.min.js+angular-route.min.js+angular-sanitize.min.js)
//cdn.jsdelivr.net/g/jquery,angularjs(angular.min.js+angular-resource.min.js+angular-animate.min.js+angular-cookies.min.js+angular-route.min.js+angular-sanitize.min.js)
Now if all files in the combination have a .css extension then the server will automatically respond with Content-Type: text/css header. In all other cases the server responds with Content-Type: application/javascript header.
//cdn.jsdelivr.net/g/angularui@0.4.0(angular-ui.min.css),animatecss@3.2.0
The first 3-4 requests will be slower, as they are not yet cached. Afterwards, these dynamic files get cached and become static files (same as all others).

Custom CDN HostingIf your project does not qualify to be hosted in GitHub or you need direct access to your files, it\'s not a problem! We can work together and setup a custom configuration for your project. This way, you can have full control over your files, without the restrictions of GitHub, and the ability to utilize the full power of jsDelivr.
This kind of custom hosting can be suitable for:
Binary hosting. Windows executable files and zips. Frequently updated files. Projects that can\'t follow jsDelivr file structure. Some other use that will blow all of our minds.Simply send an email to jimaek with a request or for more information.
jsDelivr is here to help and not to limit. Even if what you need is not listed above, feel free to contact us.
Contribute Performance DatajsDelivr uses real user performance data (also known as RUM) to make its routing decisions. This data is gathered from hundreds of websites and is used in our load balancing algorithm to make accurate decisions based on real time performance metrics.
This is why we offer the ability to all users to help us out. This data is very important and we encourage all users to participate.
All you have to do is include the following JavaScript code in your website before /body . This code is then executed each time a user visits your website. It uses their browser to test the latency to our CDN providers and gather performance and availability metrics.
These benchmarks are completely transparent to the user and do not impact on browsing in any way. We store the following information:
Performance metrics to each of our providers. Availability metrics to each of our providers. Browser’s User-Agent First three octets of the user’s IP addressOur JS code is executed with a 2 second delay and tests all of our providers unless interrupted. This testing does not impact on your website performance or user browsing experience.
