Microsoft Teams Custom Apps: From Idea to Production

Microsoft Teams has become the operating system of modern work. Developing applications for Teams means placing your tools at the center of company collaboration.

Types of Teams Apps

Teams offers several extension surfaces:

• Tabs: Embedded web pages (similar to iframes) that can be contextual to a channel or chat.
• Bots: Conversational interfaces to automate tasks and answer questions.
• Message Extensions: Allow searching and sharing information from external systems directly in the message composition box.
• Meeting Extensions: Apps that enrich the experience during meetings.

Teams Toolkit

Microsoft has greatly facilitated development with the Teams Toolkit for VS Code. This plugin offers templates, automatic resource configuration in Azure and Microsoft 365, and a simplified debugging experience.

Design for Collaboration

Creating an app for Teams is not just porting a web app. You need to think about collaboration scenarios:

• How does my app help a team make decisions?
• How can notifications (Adaptive Cards) be actionable?
• How can I use user context (Graph API) to pre-fill information?

At Avantit, we create solutions that transform Teams from a simple chat tool into a productivity hub integrated with the company's business processes.
