Summary
In this chapter, we’ve detailed the basic SharePoint and Teams logical architecture and identified the key elements you need to know before building SPFx solutions. We also covered the APIs available in the Microsoft 365 ecosystem to manipulate these elements, including the legacy SharePoint REST API (v1) and the new v2/Microsoft Graph counterpart. For both APIs, we gave examples of requests to demonstrate their usage.
We also gave you an overview of the authentication process involved for Microsoft cloud solutions through Entra ID and explained the concept of API permissions and the difference between delegated and application access.
In the next chapter, we'll guide you on your first steps with SPFx by configuring your environment and creating your first solution.
