With Klevu’s brand new SDK library, you can pull the power of AI product discovery into any JavaScript ecosystem. It simplifies development giving you more time for innovation. Our SDK brings you the data from search, smart categories and recommendations as JSON. Then you can decide how to render this information.

Another important part it does for you is analytical data sending. Making sure that everything is correct for Klevu AI to improve results. But it doesn't end just there. Our SDK library also provides you with helpers to manage filters, cache requests, simplifying pagination, etc

This library has been built for all browser based frameworks and the Node.js environment. This means that the library is agnostic and is available to use with most of the JavaScript libraries in both traditional and headless implementations.

In headless you decouple the back-end systems from the presentation or display layer i.e. frontend. Simply to say, this CMS does have a front-end layer and only the back-end is there.

Traditional web applications combine the frontend with the back-end, so when a user requests a page, the browser makes the request, the web server then requests data from the data base, processes the data, adds the data to a page template, then sends the entire page back to the browser. This leads to a complete unloading of the previous page (blank screen) and reloading of the new page. During the reloading of the new page, common elements such as fancy navigations must be reloaded and activated. The entire process takes time and is especially noticable on mobile devices with slower internet connections.

With a headless web application, the back-end and frontend are separated. The back-end exposes an API to connect to the content, while the frontend makes requests to the API and then loads the content into the page dynamically. This method although a little more complex, provides huge performance gains by only needing to partially load portions of site that are actually changing from one page request to another. In other words, the fancy navigation we mentioned previously only needs to load once. And the partially loaded portions of the page only need to request the data which is much smaller than having to also load the code necessary to display the data.

Performance is only one benefit to going headless. As previously mentioned, going headless also allows for a new level of freedom when it comes to the display of multiple data-sources which are very typical with traditional web applications. This limitation by traditional web applications is understandable. Each website is unique, like a fingerprint, and each website's requirements are also unique. Trying to make a website builder that supports every possible combination of data-sources is imposible to manage so traditional websites can only support a limited number of integrations with 3rd parties.

With headless you have the freedom to build your website the way you want and there are many frontend frameworks out there with amazing features to make it possible.
