Our Small Web Apps or SWAPs, in short, are something like the SOA for Front-End. We aim for separate deployable parts of the Front-End we have available for our Plaza partners, suppliers and internal users. In the Front-End we also encountered that we had teams waiting for each other before they could bring functionality to Pro. Basically, because the Front-End became a monolith. Besides that, people realized that we needed to deliver the same functionality in different Front-Ends. For instance content management for our internal product managers and for our external sellers (Plaza…
