Tools

Teams platform brings you different tools to build and develop your Teams apps. The following tools are available to build your app:

Tools Why do you need? Environment Test and debug
Teams Toolkit Teams Toolkit makes it simple to get started with app development for Teams. You can begin with a project template for common custom app built for your org (LOB app) scenarios or start from a sample. Save time on setup through automated app registration and configuration using Visual Studio Code and Visual Studio. Visual Studio Code: JavaScript and TypeScript
Visual Studio: .NET and Blazor		 In Visual Studio Code and Visual Studio
Yeoman generator for Teams Yeoman generator or YoTeams allows you to create Teams apps using TypeScript and JavaScript on your terms, in your preferred editor, and without any external or online dependencies. TypeScript and JavaScript NA
Teams Toolkit CLI TeamsFx CLI is a text-based command line interface (CLI) that accelerates Teams application development. It aims to provide keyboard centric experience when building Teams applications. JavaScript and .NET Use command prompt
Developer Portal for Teams Developer Portal for Teams is the primary tool for configuring, distributing, and managing your Teams apps. With Developer Portal, you can create a basic app manifest (previously known as Teams app manifest) and distribute the app to Teams. Supports all languages Developer Portal for Teams

SDKs and libraries

Teams Platform brings you different SDKs, libraries, and APIs to build and develop your Teams apps.

The following flow diagram explains the different SDKs, libraries, and its relations:

Screenshot shows you the list of all tools and SDKs that are available for you to build Teams apps.

Library that requires another library to build apps. Your project automatically pulls into another library.
Library that passes your app a reference to another library.
Library often used with another library, but there's no formal dependency.
Library that's underlying service or API.

TeamsFx SDK TeamsFx simplifies your tasks by using Teams single sign-on (SSO) and accessing cloud resources into single-line statements with zero configuration. Depends on Bot Framework SDK, Teams JavaScript client library, and Microsoft Graph SDK.
You can use it with Teams AI Library and Adaptive Cards.
Teams JavaScript client library The Teams JavaScript client library (TeamsJS) enables you to create hosted experiences within Teams, Microsoft 365 app, and Outlook. These experiences involve hosting your app content in an iFrame. You can pass the reference to SharePoint Framework (SPFx).
You can use it with Microsoft Graph SDK, Adaptive Cards, and Fluent UI React components.
SharePoint Framework (SPFx) The SharePoint Framework (SPFx) offers a page and web part model that fully supports client-side SharePoint development, seamlessly integrates with SharePoint data, and extends Microsoft Teams and Microsoft Viva. You can use it with Microsoft Graph SDK, Adaptive Cards, and Fluent UI React components.
Based on SharePoint REST API.
Live Share SDK Live Share is an SDK created to turn Teams apps into collaborative multi-user experiences without requiring dedicated back-end code to be written. You can use it with Microsoft Graph SDK, Adaptive Cards, and Fluent UI React components.
You can pass the reference to Teams JavaScript client library.

Core SDKs and libraries to build Teams app

SDKs and libraries Why do you need? Related SDKs and libraries
Bot Framework SDK Microsoft Bot Framework and Azure AI Bot Service are a collection of libraries, tools, and services that enable you to build, test, deploy, and manage intelligent bots. The Bot Framework includes a modular and extensible SDK for building bots and connecting to AI services. Based on Azure Bot Service.
Microsoft Graph SDKs The Microsoft Graph SDKs are designed to simplify the creation of high-quality, efficient, and resilient applications that access Microsoft Graph. The SDKs include two components such as service library and core library. Based on Microsoft Graph.
Teams AI library Teams AI library is a Teams-centric interface to GPT-based common language models and user intent engines. This reduces the requirement for you to handle on complex and expensive tasks of writing and maintaining conversational bot logic to integrate with large language models (LLMs). Depends on Bot Framework SDK.
Based on Azure OpenAI.

Additional libraries and UI utilities to build Teams apps

Adaptive cards An Adaptive Card is a customizable card that can contain any combination of text, speech, images, buttons, and input fields. You can use it with TeamsFx SDK, Teams JavaScript client library, and SharePoint Framework (SPFx).
Fluent UI React components Fluent UI React components are a collection of UI elements and tools that come from combining various React-based component libraries used in production, like @fluentui/react and @fluentui/react-northstar. You can use it with Teams JavaScript client library and SharePoint Framework (SPFx).
Fluid Framework Fluid Framework consists of client libraries that help distribute and synchronize shared state. These libraries enable multiple clients to simultaneously create and operate on shared data structures using coding patterns similar to those used to work with local data. You can pass the reference to Live Share SDK.
Based on Azure Fluid Relay.
