Web dependencies, or libraries like Vue and bootstrap, underscore, Dojo and font-awesome have become a standard part of the web. Most developers use services like CDNJS to make it easier to load these assets, libraries, or dependencies on clients’ browsers.
For most developers who have been in the trade for at least a decade, Google has always been the only, and probably, most preferred CDN provider to make loading JS on the web easier and faster. To be fair, there is the added benefit of everything being completely free and very reliable. Google, however, doesn’t consider its CDN service a priority. It can be slow to update and upgrade.
What is CDNJS?
For the longest time, Google has been the most used CDN service by developers to speed up loading frontend libraries like JQUERY. Google has, however, been focusing their CDN service on popular libraries for a long time. They also devote less resources and time to it.
CDNJS is unique because it hosts millions of JS libraries on its servers. This makes it stand out from other services. CDNJS’ source code is also available for free to other developers.
The service offers a variety of libraries, including cdnjs bootstrap and cdnjs jQuery.
