Expected or Desired Behavior

I believe this is a bug... as I can't find a mention of this in the release notes for 1.8.1.

In SPFx v1.8.1, when you create new SPFx project, you should be able to access the MSFT Teams context via this.context.microsoftTeams.... This worked in v1.8.0, but in 1.8.1, the microsoftTeams property is not defined.

Digging deeper, the BaseClientSideWebPart WebPartContext object appears to have changed from v1.8.0 => v1.8.1:

/* Excluded from this release type: microsoftTeams */

Whereas in SPFx 1.8.0 it was:

readonly microsoftTeams?: typeof teamsJs;

Observed Behavior

This code triggers a build error in an SPFx v1.8.1 web part project:

protected onInit(): Promise<void> {
  return new Promise<void>((resolve, reject) => {
    if (this.context.microsoftTeams) {
      this.context.microsoftTeams.getContext(context => {
        console.log('got teams context');
        resolve();
      });
    } else {
      resolve();
    }
  });
}

Steps to Reproduce

• ensure install SPFx v1.8.1 is installed
• create new SFPx web part

• add the following code to the web part

  protected onInit(): Promise<void> {
    return new Promise<void>((resolve, reject) => {
      if (this.context.microsoftTeams) {
        this.context.microsoftTeams.getContext(context => {
          console.log('teams context', context);
          resolve();
        });
      } else {
        resolve();
      }
    });
  }
  

• run gulp build & observe errors

• repeat the same process above, but with SPFx v1.8.0 installed... observe it builds without error

So, bit of background. The public typings generation process went squirelly when we released 1.8.0, and it was fixed for 1.8.1. However, it looks like the microsoftTeams property didn't get moved from beta -> public, so when the typings cleanup process ran, it removed it from the public typings. For now, you can work around this by including the beta packages. We will fix this in the next drop. Thanks for the heads up.

Fixed with the 1.8.2 release, so closing this from here. Thanks for reporting this and sorry for the inconvenience caused by this regression.
