A Single-Page Application (SPA for short) is a web app implementation that loads only a single web document, and then updates the body content of that single document via JavaScript APIs when different content is to be shown.
This allows users to use websites without loading whole new pages from the server, which can result in performance gains and a more dynamic experience, with some tradeoff disadvantages such as SEO, more effort required to maintain state, implement navigation, and do meaningful performance monitoring.
It is very easy to use OptiMonk with an SPA site. If you would like to use OptiMonk on a website that is using a single-page application (SPA), please contact us at [email protected], and we would be happy to help you set it up :)
