Sequential workflow adaptive cards Node.js

Preview Image

Try it yourself - experience the App in your Microsoft Teams client

Please find below demo manifest which is deployed on Microsoft Azure and you can try it yourself by uploading the app package (.zip file link below) to your teams and/or as a personal app. (Sideloading must be enabled for your tenant, see steps here).

Sequential workflow adaptive cards: Manifest

This App talks about the Teams Bot User Specific Views and Sequential Workflows in adaptive card with Node JS

This bot has been created using Bot Framework v4, it shows how to create a simple bot that accepts food order using Adaptive Cards V1.4

This is a sample app that provides an experience of managing incidents. This sample makes use of Teams platform capabilities like Universal Bots with below mentioned capabilities. User Specific Views Sequential Workflows Up to date cards

Key features

  • Incident Creation
    • Choose Category
    • Choose Sub Category
    • Create Incident
    • Edit/ Approve/ Reject Incident
  • List Incidents

Prerequisites

  • Office 365 tenant. You can get a free tenant for development use by signing up for the Office 365 Developer Program.

  • To test locally, NodeJS must be installed on your development machine (version 10.14 or higher).

    # determine node version
node --version

  • dev tunnel or ngrok latest version or equivalent tunnelling solution

  • If you are using Ngrok to test locally, you'll need Ngrok installed on your development machine. Make sure you've downloaded and installed Ngrok on your local machine. ngrok will tunnel requests from the Internet to your local computer and terminate the SSL connection from Teams.

NOTE: The free ngrok plan will generate a new URL every time you run it, which requires you to update your Azure AD registration, the Teams app manifest, and the project configuration. A paid account with a permanent ngrok URL is recommended.

Run the app (Using Teams Toolkit for Visual Studio Code)

The simplest way to run this sample in Teams is to use Teams Toolkit for Visual Studio Code.

  1. Ensure you have downloaded and installed Visual Studio Code
  2. Install the Teams Toolkit extension
  3. Select File > Open Folder in VS Code and choose this samples directory from the repo
  4. Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps
  5. Select Debug > Start Debugging or F5 to run the app in a Teams web client.
  6. In the browser that launches, select the Add button to install the app to Teams.

If you do not have permission to upload custom apps (sideloading), Teams Toolkit will recommend creating and using a Microsoft 365 Developer Program account - a free program to get your own dev environment sandbox that includes Teams.

Setup

  1. Register a new application in the Microsoft Entra ID – App Registrations portal.

  2. Setup for Bot

    • Register a Microsoft Entra ID aap registration in Azure portal.
    • Also, register a bot with Azure Bot Service, following the instructions here.
    • Ensure that you've enabled the Teams Channel
    • While registering the bot, use https://<your_tunnel_domain>/api/messages as the messaging endpoint.

    NOTE: When you create your app registration, you will create an App ID and App password - make sure you keep these for later.

  3. Setup NGROK

  • Run ngrok - point to port 3978

    ngrok http 3978 --host-header="localhost:3978"

    Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

    devtunnel host -p 3978 --allow-anonymous
  1. Setup for code

  • Clone the repository

    git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

  • In a console, navigate to samples/bot-sequential-flow-adaptive-cards/nodejs

    cd samples/bot-sequential-flow-adaptive-cards/nodejs

  • Update the .env configuration for the bot to use the MicrosoftAppId (Microsoft App Id) and MicrosoftAppPassword (App Password) from the Bot Framework registration.

NOTE: the App Password is referred to as the client secret in the azure portal and you can always create a new client secret anytime.

  • Install modules & Run the NodeJS Server

    • Server will run on PORT: 3978
    • Open a terminal and navigate to project root directory
    npm run server

    This command is equivalent to: npm install > npm start

  1. Setup Manifest for Teams

  • This step is specific to Teams.

    • Edit the manifest.json contained in the ./appManifest folder to replace your Microsoft App Id (that was created when you registered your app registration earlier) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
    • Edit the manifest.json for validDomains and replace {{domain-name}} with base Url of your domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
    • Zip up the contents of the appManifest folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)

  • Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

    • Go to Microsoft Teams. From the lower left corner, select Apps
    • From the lower left corner, choose Upload a custom App
    • Go to your project directory, the ./appManifest folder, select the zip folder, and choose Open.
    • Select Add in the pop-up dialog box. Your app is uploaded to Teams.

Note: If you are facing any issue in your app, please uncomment this line and put your debugger for local debug.
