This document summarizes a presentation about building Microsoft Teams apps using the SharePoint Framework (SPFx). It introduces key concepts like Tabs, Bots, Messaging Extensions and how they can be used to build Teams capabilities. It also provides an overview of how to create a Teams tab using an existing SPFx web part and details the process for packaging and deploying the web part to Teams. Several tips are provided around testing in Teams and supporting both SharePoint and Teams contexts. The presentation concludes with a demo of a sample SPFx web part integrated as a Teams tab.

16. Make your Web Part available as a Teams tab
{
// ...
"supportedHosts": ["SharePointWebPart", "TeamsTab"],
// ...
}
HelloWorldWebPart.json

17. Create a teams folder
Add an icon and an outline image for
your app using your web part id
*Only required if you have an existing pre SPFx 1.8 web part
Add the required icons

18. Bundle and package!
gulp bundle
gulp package-solution

19. Syncing it to Microsoft Teams

20. Magic!

21. SharePoint Framewok Teams tabs use a jumpstart page that handles
authentication
/_layouts/teamslogon.aspx?spfx=true&dest={Url}
The web part is hosted on a page that holds “only” a single web part canvas
{Url}/_layouts/15/teamshostedapp.aspx?list={ListId}&id=1&webPartI
nstanceId={WebPartInstanceId}
What’s the trick?

26. Understanding the Teams Context
if (this.context.microsoftTeams) {
this.context.microsoftTeams.getContext(context => {
this._teamsContext = context;
resolve(undefined);
});
} else {
resolve(undefined);
}
HelloWorldWebPart.ts

27. Supporting SP and Teams themes
if(this._isRunningInTeams()) {
import("./HelloWorld.Teams.module.scss");
if(this.props.teamsContext.theme == "dark") {
import("./HelloWorld.Teams.Dark.module.scss");
}
}
HelloWorld.tsx

28. Use Office UI Fabric for anything that
would be consumed through SharePoint
and Teams
Use Fluent UI (Codename Stardust,
codename Semantic UI) if your goal is to
deliver a Teams-only SPFx web part
Making it event prettier

29. Don’t just test in the Workbench, test in
Teams
The web experience is nice, but
sometimes misleading
Test in your production environment
(SSO, Conditional Access, etc.)
Use the Developer preview option
Test with the real thing

30. It can be just about Teams…
{
// ...
"hideFromToolbox": true,
// ...
}
HelloWorldWebPart.json
