Teams Message Reactions Bot Node.js Sample

Message the bot and it will respond with an 'Echo: [your message]'. Add a message reaction to the bot's response, and the bot will reply accordingly.

• Interaction with bot

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).

Teams Message Reactions Bot: Manifest

Prerequisites

• Microsoft Teams is installed and you have an account
• NodeJS
• ngrok or equivalent tunnelling solution

Setup

Note these instructions are for running the sample on your local machine, the tunnelling solution is required because the Teams service needs to call into the bot.

1. Run ngrok - point to port 3978

   ngrok http --host-header=rewrite 3978

Setup for bot

In Azure portal, create a Azure Bot resource. - For bot handle, make up a name. - Select "Use existing app registration" (Create the app registration in Azure Active Directory beforehand.) - If you don't have an Azure account create an Azure free account here

In the new Azure Bot resource in the Portal, - Ensure that you've enabled the Teams Channel - In Settings/Configuration/Messaging endpoint, enter the current https URL you were given by running ngrok. Append with the path /api/messages

Setup for code

1. Clone the repository

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

2. In a terminal, navigate to samples/bot-message-reaction/nodejs

3. Install modules

   npm install

4. Update the .env configuration for the bot to use the Microsoft App Id and 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.) MicrosoftAppTenantId will be the id for the tenant where application is registered.

• Also, set MicrosoftAppType in the .env. (Allowed values are: MultiTenant(default), SingleTenant, UserAssignedMSI)

1. Run your bot at the command line:

   npm start

2. This step is specific to Teams.

   • Edit the manifest.json contained in the appPackage folder to replace your Microsoft App Id (that was created when you registered your bot earlier) everywhere you see the place holder string <<YOUR-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 with base Url domain. E.g. if you are using ngrok it would be https://1234.ngrok.io then your domain-name will be 1234.ngrok.io.
   • Zip up the contents of the appPackage 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 Teams Apps/Manage your apps click "Upload an app". Browse to and Open the .zip file. At the next dialog, click the Add button.)
   • Add the app in personal/groupchat/team scope (supported scopes)

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

Running the sample

Message the bot and it will respond with an 'Echo: [your message]'. Add a message reaction to the bots response, and the bot will reply accordingly.
