Using SharePoint Framework you can extend portals on Microsoft 365 and expose your apps where people work. Here are some resources to get you started.
What is SharePoint Framework and why should you care
SharePoint Framework is a development model for building apps on Microsoft 365. Originally, it started as a way to extend SharePoint portals. Nowadays, it allows you to also build apps for Microsoft Teams.
When you use SharePoint Framework to build your apps, you don't need to worry about hosting and auth. You can build your app using any client-side framework you want and easily deploy your app to your users.
