These web apps are independent from each other, they have separate code repositories, backing services, deployment pipelines, and are ideally owned by different teams. I’ve seen SaaS platforms that ended up becoming a huge but fragile monolithic web application with redundant functions lumped within. Badly written code can cost days to weeks of developer’s time, but bad architectural decisions can cost months to years in comparison. – the piece of code below will be even much nicer: , so you may be sure that you will miss nothing.
