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.

Fastest JavaScript CDN

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.

In light of this, a new entrant into the JavaScript CDN service aimed to provide a more robust and FOSS frontend JS library hosting service for website owners relying on JQUERY for their websites’ functionality and visual interaction through libraries.

What is CDNJS and how can it help your website or web applications in JavaScript? What makes CDNJS different from other JavaScript and general-purpose CDN services? This ultimate CDNJS guide will answer these and other questions.

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 was the brainchild of Ryan Kirkman and Thomas Davis, two startup founders. It aims to increase the number of libraries that can be loaded through a CDN and make it more reliable and up-to-date than existing services. CDNJS hosts many JavaScript libraries and is an open-source CDN service. These libraries are not available on any other CDN, whether free or proprietary. This means that they must have been hosted by CDNJS in the past.

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.

  • Tween.js
  • Tweetnacl
  • Take a sip
  • Between.js
  • Embetty
  • Kalendae
  • Bootcards
  • Three.js is one of many smaller libraries.

According to CDNJS data, more than 3,900 JS libraries are currently stored on CDNJS servers. The small project has also grown in support and community. CDNJS had more than eight hundred contributors to its community at the time this guide was published. Since its inception, the service has attracted a population of five million users. This is 9.2% of all websites today.

Here are some things CDNJS stands for:

  • CDNJS, an alternative JavaScript content delivery system, is able to deliver important JavaScript libraries and other assets. It rivals Google. This free CDN offers more libraries than other services and includes small libraries that are often overlooked by other CDNs.
  • CDNJS is an open-source, free content delivery network that has its code base derived from more than eight hundred contributors around the world. CDNJS is also completely free, and will likely remain so for the foreseeable future.

How CDNJS works

Many developers are familiar with content delivery networks and may already be aware of it.How to Use CDNJSIt might work

In a nutshell, CDNJS is a free distributed JS library delivery service that you can use to host your JS dependencies/libraries outside of your server. It is robust. cloud CDN CDNJS is a storage service that will provide all JS libraries used on your web sites or web applications to your users.

CDNJS makes websites load faster and more accessible to visitors, regardless of where they are located and their internet connection. Developers can benefit from this free service because most frontend JavaScript library can be too heavy to be delivered via individual servers. Instead of downloading and hosting the library on their own web server, they can point to the CDNJS-hosted CD.

Then, you can reference it in your code. CDNJS has excellent documentation that provides detailed instructions for how to use the service for any JS library you may be using at any time.

These are some practical examples of code How to Use CDNJS For frontend JavaScript libraries, please see the following:

JavaScript: Why you need a CDN

JavaScript dependencies represent the most complex components of the web today. One website or web application could contain five or more JS libraries. This can impact the site’s performance, speed, and appearance to users. There are many benefits to hosting your JS libraries on a CDN such as CDNJS.

Rapid loading

CDN hosted JS library will load quicker than those on your web server. This will improve your website’s performance, user experience and overall performance regardless of where they are located or the power of their browsing devices.

Available

No matter what happens to the storage on your web server, your JavaScript libraries will still be available for use on your website.

Distributed servers

Many CDNs that host JS libraries have a distributed server structure. This means that JS libraries can be retrieved from the closest servers to your users. This makes it easier to load heavy JS libraries.

Cost-saving

Many JS CDN services, such as CDNJS, are free. This saves you money on extra storage for your web server.

Security

The JS library that is being loaded onto your website is guaranteed to be secure. It has not been altered or stolen without your permission.

Browser caching

Chrome, a modern browser, will recognize a CDNJS URL quickly and download the library into a user’s cache. The library will be available to the next person who visits your website. The browser will not use the cached library, however, if the CDN address is already present on your website.
