It's an easy to use library which make it simple for developers to integrate with JavaScript frameworks like Angular/ React etc. The support of nodejs is good enough in this product. I had used Sajax system in my projects. But its performance was not very good. Sometimes it took time to load the page and sometimes we got some problems while running nodejs server in production mode. If your looking for a robust library with high performance then go ahead. I am using this in one of my current project and i can say that it has helped me a lot. I have made several web applications using this. We need to integrate our third party APIs with the website. It helps us to handle the data from both backend and frontend side using Sajax system.
