Hosting Web Apps

The App class lets you host web apps in the agent. This can be used for an efficient inner loop when building a complex app using Microsoft 365 Agents Toolkit, as it lets you build, deploy, and sideload both an agent and a Tab app inside of Teams in a single step. It's also useful in production scenarios, as it makes it straight-forward to host a simple experience such as an agent configuration page or a Dialog.

To host a static tab web app, call the app.AddTab() function and provide an app name and a path to a folder containing an index.html file to be served up.

app.AddTab("myApp", "Web/bin");

This registers a route that is hosted at http://localhost:{PORT}/tabs/myApp or https://{BOT_DOMAIN}/tabs/myApp.
