CDN public library refers to the common stock of JS on the CDN node, in order to facilitate the majority of developers called directly. Compared with the JS stock on a stand-alone server, CDN public library is more stable, high-speed. General CDN public library will contain all of the world's most popular open source JavaScript library, you can be on their own web pages directly through the script reference these resources. Not only does this save you traffic, but also through the CDN acceleration, faster access speed.
Currently some of the larger public CDN services:
Baidu CDN Public Library
Baidu public CDN provides for the application owners a stable, reliable, high-speed services, including all of the world's most popular open source JavaScript library.
Official website: http: //developer.baidu.com/wiki/index.php title = docs / cplat / libs?
Ps: Baidu speed now, and Sina should be about the same. But several jQuery version less than SAE, other libraries should be similar.
Sina cloud computing CDN Public Library
Sina Sina cloud computing research and development center under the department, is responsible for strategic planning in Sina cloud computing, technology development and platform operators work. Key products include application cloud platform Sina App Engine (referred to as SAE).
SAE CDN node coverage in major cities nationwide multiplex (Telecom, China Unicom, mobile, education) backbone network, enabling developers to easily use high-quality CDN services.
Official website: http: //lib.sinaapp.com/
Ps: online evaluation of speed, said Sina better than Baidu. Personally I did not feel it. Pro-test middle of the night when there have been several cases loaded slow (do not know the other owners encountered no).
Shoot a cloud JS library CDN service
Cloud storage is they shoot Hangzhou Wei-Network Co., Ltd's project, established in June 2005, mainly for the early network they shoot, they shoot pictures Picture Manager offers cloud storage / cloud computing services, open to all users in February 2010 use.
The main focus on mass storage and distribution of small files and pictures of cloud computing. Providing two core services: static file cloud storage, CDN speed up processing.
Official website: http: //jscdn.upai.com/
Ps: it shoots cloud js library provides commonly used JavaScript libraries CDN service. Cdn be an early start to accelerate the service. Speed and stability is also good. Js library but a little less, some avant-garde js library may not be available.
Seven cattle cloud storage open static files CDN
JS libraries like storage on Google Ajax Library, Microsoft ASP.net CDN, SAE, Baidu, Upyun and other CDN are provided free of charge, but using them but had some limitations, because they only provide some JS library. But seven cattle cloud storage provides a comprehensive collection of excellent open source database as a warehouse, and offer free CDN acceleration service.
Official website: http: //www.staticfile.org/
Ps: At the same time, open static files CDN also provide access to open source library source access, so that everyone can submit open source libraries, including JS, CSS, image and swf and other static files.
Above these, my personal test results: Baidu cloud should be the fastest, shoot too little service, almost without regard to Ali also said to provide a public cloud CDN services, but can not find the official website of the specific service page, temporarily. do not say
360 CDN site guards the front of public library
Hosted on many of the country's 360 CDN nodes, covering telecommunications, China Unicom, mobile operators and other mainstream lines, you can be on their own web pages directly through the script reference these resources to the site access speed instantaneous speed!
Just replace a domain name can continue to use front-end and public libraries offer free Google font library, allowing site access speed instantaneous speed.
Official website: http: //libs.useso.com/
Ps: 360 pace is now faster and faster. A variety of technical and service updates provide the speed is fast. 360CDN service only recently introduced (looks like Google is mainly the reason for the wall). Provides most of the front js library, still above its own server front-end cache Google's free public library and the font library, this be other domestic cdn public library does not have. Speed and stability is also good, of course, but also slightly down compared to Baidu and Sina (pro-test broadband lines in some places will be broken, and perhaps a small part of it). After all, we have not served long. Specific use to see WordPress 360CDN use public libraries to solve Google Open Sans font can not be loaded .
At present, some foreign large public CDN services:
CDNJS
CDNJS provides a very complete JavaScript library, whether it is popular or unpopular readily available. If you feel that what they lack useful libraries, can also submit themselves to the site, the split will be approved after CDNJS js files for you! The service is a combination of CloudFlare, Pingdom and S3Stat, stability and speed can not be overemphasized. JavaScript Libraries CDNJS provided all of the columns in the homepage, users can search. These libraries have marked the version number, the original label and maintain the website link.
Official website: http: //www.cdnjs.com/
Ps: CDNJS should be regarded as the most complete of the JS library. Stores most of the major JS libraries, and even CSS, image and swf, but many excellent domestic open source library is not. Many foreign avant-garde Js libraries can be found in CDNJS large. Although they are not the domestic rate of several other domestic CDN services, but relatively speaking, actually it can be.
Of course, you can also use CDNJS domestic mirror sites provided they shoot people cloud the path to refer to the relevant JS and CSS files.
Domestic Mirror: http: //www.cdnjs.cn/
CDNJS they shoot domestic mirrored hosted cloud storage, but a variety of JS or CSS library cloud than they shoot themselves out of a lot of rich JS libraries, and updated simultaneously and supports https protocol every day.
Google Hosted Libraries
Google produced, it will be a fine. Although the recent Google line of products is the wall, and even basic Google search service can not be used. But Google's public CDN public library should be the most powerful, like the avant-garde in which the various code libraries and Google Web Font font library, several major domestic public almost never provide CDN services support.
Official website: https: //developers.google.com/speed/libraries/
Ps: Of course, Google can not open how to do? In addition to using domestic cdn libraries, there is no good solution. Such as: js library does not provide domestic cdn use seven cattle cdn accelerated cloud storage service, Google Fonts Open Sans font library use 360CDN public library in place and so on.
Microsoft ASP.net CDN
ASP.NET development team launched a new Microsoft Ajax CDN (Content Delivery Network, the content distribution network) service, which provides caching support for AJAX libraries (including jQuery and ASP.NET AJAX) is. The service is free and does not require any registration, can be used for commercial or non-commercial purposes.
Official website: http: //www.asp.net/ajaxlibrary/cdn.ashx
Ps: Microsoft produced, naturally not too bad. Although in the heavenly, the speed is still not too slow (of course inferior to other domestic cdn).
jsDelivr
MaxCDN is a relatively cheap price of CDN companies in the global distribution of a large number of nodes. jsDelivr is based MaxCDN a free open-source CDN solutions to help developers and owners. jsDelivr contains JavaScript library, jQuery plug-ins, CSS frameworks, fonts, etc. commonly used static resources on the Web.
Official website: http: //www.jsdelivr.com/
Ps: the number of nodes per CDN is a concern to everyone, jsDelivr total with 13 nodes. And CDNJS loading speed almost all the same, domestic users recommend the best use of domestic CDN service. You can test yourself and see.
Summary: Most of these public libraries CDN distinctive. You can go selectively own use. Speed and stability to the country Baidu and Sina is the best (of course this is a personal opinion). Given Google has been the wall, all services on the Google still move on as quickly as possible, the use of domestic CDN public library service bar.
