What’s SharePoint Framework? 🚀

SharePoint Framework is the most widely used extensibility option in Microsoft 365 with tens of millions of end users each month for the custom components built by developers for Microsoft Teams, Microsoft Viva and SharePoint. It’s the easiest way to build developer extensibility for Microsoft 365 and it’s taken advantage by thousands of partners and customers on building custom experiences for end users.

You can build SharePoint Framework powered solutions by using SharePoint Framework Yeoman Generator, Microsoft Teams Toolkit, or with the SharePoint Framework Toolkit. Key advantage is the flexibility of automatic hosting with the option to use the exact same component across the different hosts without any code level changes. This is designed to maximize the value of your development investments regardless of which primary host you are targeting.

Key capabilities of the SharePoint Framework for Microsoft 365 are the following:

• Content Driven Applications – SharePoint Framework can be used to build content driven applications on surfacing information easily from Microsoft 365 with Microsoft Graph or to integrate with externally hosted content.
• Automatic Single Sign On – SharePoint Framework components have automatic and seamless SSO included for all platforms they are hosted. No specific consents needed from Microsoft 365 end users.
• Automatic hosting – SharePoint Framework components are automatically hosted in SharePoint without additional maintenance or operational costs.
• Industry standard tooling – SharePoint Framework is using standard web stack tooling with node, npm, TypeScript and any JavaScript framework of your preference. Just standard web skill to succeed without any proprietary tooling.

SharePoint Framework has also made the permission and token management for accessing the data in Microsoft 365 easy. You will be using the awesome Microsoft Graph APIs for accessing business data and you can further simplify the development of SharePoint Framework components by taking advantage of the Microsoft Graph Toolkit, which provides reusable controls with data connectivity to Microsoft Graph.
