Leveraging the SPFx for Microsoft Teams

There are several advantages of using SPFx with Teams tabs or Teams apps, as mentioned here:

• Hosted with SharePoint: You have the actual code hosted on a SharePoint site that relates to Teams, so you do not need to worry about seeing where you can host the code on Teams customizations. Also, it simplifies your deployment operations by deploying them in a SharePoint Online App Catalog and synchronizing to the Teams store from there.
• Graph API support: You can consume the Graph API easily with a web part using GraphHTTPClient or ADAL.JS and get the code running.
• Reuse implementation: You can quickly implement the same customization on SharePoint and Microsoft Teams, saving a lot of development time.
• Seamless collaboration: Combining the collaborative features of Microsoft Teams with the content management features of SharePoint, SPFx solutions enable seamless collaboration and communication among team members.
