Developing solutions for SharePoint Online

By now, you should have a basic understanding of what SharePoint Online is, how information is structured within SPO, and how you can provision your own developer site that can be used as a playground for your upcoming custom deployments.

Next, we'll look at what kind of solutions developers can build for SPO. We'll start with the classic and oldest models and move up the ladder to the add-in approach. This excludes the latest addition to the family, the SharePoint Framework (SPFx), which the book will cover in deep detail in the following chapters.

We feel it's crucial to understand how things were built for previous (and sometimes current) versions of SharePoint, even if at a pretty high level, in order to respect and understand the decision and options we have at our disposal today.
