CDN public library refers to placing commonly used JS inventory on CDN nodes to facilitate direct access by developers. Compared with placing JS inventory on a stand-alone server, CDN public libraries are more stable and fast-paced. Public CDNs provide stable, reliable, and high-speed services for your applications, including all the most popular open-source JavaScript libraries in the world.
A CDN public library will contain all the most popular open source JavaScript libraries in the world, and you can reference these resources directly on your web pages via script tags. Doing so will not only save you traffic, but also get faster access speed with CDN acceleration. There is also a reprint of an article titled "Building a Local CDN to Speed Up the Access Speed of Websites Like StackOverflow." " is to solve the problem that some websites cannot be opened or displayed incompletely because of Google being blocked.
The reason is simple, under the relatively stable service, its JS library is the most complete, many good CDNs are synchronized with its repositories, and the well-known JSLite I wrote are included in it?, which moved me badly?, this directly leads to other big CDN service providers, all have JSLite libraries, it's great.
CDNJS
CDNJS provides a very complete JavaScript library, both popular and unpopular. If you think they are missing some useful libraries, you can also submit them to the website yourself, and after passing the review, CDNJS will split the js files for you! This service is a combination of CloudFlare, Pingdom, and S3Stat, and stability and speed are not a problem. All JavaScript Libraries provided by CDNJS are listed on the homepage of the website, and users can search for them directly. These JS libraries are marked with version numbers, tags, and links to the original maintenance website.

PS: CDNJS should be considered the most complete JS library. Most of the mainstream JS libraries are stored, even CSS, image, and swf, but many excellent domestic open source libraries do not have them. Many foreign avant-garde Js libraries can be found in CDNJS. Even JSLite I wrote myself took the initiative to include it, and I was so moved
Of course, you can also use the CDNJS provided by the Chinese to reference the relevant JS and CSS files.

Ps: CDNJS国内镜像托管在又拍云存储，但是各种JS或者CSS类库比又拍云自己出的JS库丰富很多,而且每天同步更新且支持https协议 (和可惜最近网站提示未备案已经打不开了)。
CDNJS.net
This is a copycat product at first glance, cdnjs.com data, because I wrote a JSLite only this cdnjs.com included, I didn't expect this .net website to be included, it can be seen that it is really a copycat, but it seems to be using Alibaba Cloud CDN acceleration.

BootCDN
BootCDN is a free CDN service for open source projects supported and maintained by Bootstrap Chinese website, committed to providing stable and fast free CDN services for excellent open source projects such as Bootstrap, jQuery, and Angular. The open source projects included in BootCDN are mainly synchronized with the cdnjs repository.

Baidu CDN public database
Baidu Public CDN provides stable, reliable, and high-speed services for webmasters' applications, including all the most popular open-source JavaScript libraries in the world.
Official Website:The hyperlink login is visible.
PS: Baidu's speed should be similar to Sina's at present. However, jQuery has a few fewer versions than SAE, and other libraries should be similar.
Sina Cloud Computing CDN Public Library
Sina Cloud Computing is a department under Sina R&D Center, mainly responsible for Sina's strategic planning, technology research and development and platform operation in the field of cloud computing. The main products include the application cloud platform Sina App Engine (SAE).
SAE's CDN nodes cover multiple (telecom, Unicom, mobile, and education) backbone networks in major cities across the country, enabling developers to easily use high-quality CDN services.
Official Website:The hyperlink login is visible.
PS: There are reviews on the Internet that Sina is faster than Baidu's. I don't feel it. In the middle of the night, there were several slow loading situations (I don't know if other webmasters have encountered it).
It also provides a JS library CDN service
Youpai Cloud Storage is a project of Hangzhou Weiju Network Co., Ltd., established in June 2005, mainly to provide image cloud storage/cloud computing services for Youpai Network and Youpai Picture Manager in the early stage, and was opened to all users in February 2010.
It mainly focuses on the storage and distribution of massive small files and the field of image cloud computing. It provides two core services: static file cloud storage and CDN accelerated processing.

PS: You also said that the js library provides a commonly used JavaScript library CDN service. It is considered an early CDN acceleration service. Speed and stability are also good. However, there are a few js libraries, and some avant-garde js libraries may not be available.
Qiniu Cloud Storage opens static file CDN
Storage of JS libraries that are free on CDNs such as Google Ajax Library, Microsoft ASP.net CDN, SAE, Baidu, Upyun, etc., but they are somewhat limited in use because they only provide some JS libraries. However, Qiniu Cloud Storage provides a warehouse with the most comprehensive collection of excellent open source libraries as possible, and provides CDN acceleration services for free.

PS: At the same time, the Open Static File CDN also provides an entry point for open source library source access, allowing anyone to submit open source libraries, including static files such as JS, CSS, image, and swf. The above ones, my personal test results: Baidu Cloud should be the fastest, and there are too few services, almost no need to consider it. Alibaba Cloud is also said to provide public CDN services, but the official website cannot find a specific service page, so I won't talk about it for the time being
360 Website Guard CDN front-end public database
Hosted on 360 CDN nodes across the country, covering mainstream operator lines such as China Telecom, China Unicom, and China Mobile, you can directly reference these resources through script tags on your own web pages, so that the website access speed can be instantly accelerated!
Just replace a domain name and continue to use Google's front-end public library and free font library, which instantly speeds up website access.

PS: The pace of 360 is getting faster and faster. The speed at which various technologies and services offered are updated is fast. Google is walled, should it be the reason why it was launched?
Google Hosted Libraries
Google products must be high-quality. Although Google's entire product line has been blocked recently, even the basic Google search service is no longer available. However, Google's public CDN public library should be the most powerful, such as the avant-garde code libraries and Google Web Font font libraries, which are almost not supported by several major public CDN services in China.
Official Website:The hyperlink login is visible.
PS: Of course, what if Google can't open it? There is no better way than to use domestic CDN libraries. For example, the JS library that is not provided by domestic CDN uses the CDN acceleration service of Qiniu Cloud Storage, and the Google Fonts Open Sans font library uses the 360CDN public library instead.
Microsoft ASP.net CDN
ASP.NET the development team launched a new Microsoft Ajax CDN (Content Delivery Network) service that provides caching support for AJAX libraries, including jQuery and ASP.NET AJAX. The service is free of charge and does not require any registration and can be used for commercial or non-commercial use.

PS: Produced by Microsoft, it is naturally not too bad. Although in the Celestial Empire, the speed is still not too slow (of course, it is not as good as other CDNs in China).
jsDelivr
MaxCDN is a relatively inexpensive CDN company with many nodes distributed around the world. jsDelivr is a free and open-source CDN solution based on MaxCDN to help developers and webmasters. jsDelivr contains JavaScript libraries, jQuery plugins, CSS frameworks, fonts, and other static resources commonly used on the web.
Official Website:The hyperlink login is visible.
PS: The number of nodes in each CDN is a concern for everyone, and jsDelivr provides a total of 13 nodes. The loading speed is basically similar to that of CDNJS, and domestic users are recommended to use the best domestic CDN service. You can test it yourself.
Sunshine Network commonly uses front-end public databases

CSS.Net
The domestic CDN node sponsor is Zhuji Jiesu Network Technology Co., Ltd., and the foreign CDN node sponsor is VPS. TO

Summary: Most of these CDN public libraries have their own characteristics. You can use it selectively. The speed and stability are the best in Baidu and Sina in China, obviously the feeling of this kind of star factory is very reliable, but Qiniu and Youpaiyun are also very good. Since Google has been blocked, all Google services should be transferred as soon as possible and use the domestic CDN public library service. |
