This documents outlines the steps required to add your changes to Microsoft Teams Test App and run the app in your local environment.

Code Setup and contribution

Github Link

microsoft-teams-test-tab on github

Fork

It is recommended to fork the repo into your github account. This will be handy when you are contributing back to the repo.

Click here to fork

Clone

Clone the repo from your fork

$ git clone git@github.com:<username>/microsoft-teams-test-tab.git

You can now create a branch in your forked version and start writing code for adding the missing SDK event.

Add your module

The only file you need to change is under src > app.js

Just add a code block identical to the one shown below

addModule({
      name: "navigateToTab",
      initializedRequired: true,
      hasOutput: true,
      inputs: [{
        type: "object",
        name: "tabInstance",
      }],
      action: (tabInstance: microsoftTeams.TabInstance, output) => {
        microsoftTeams.navigateToTab(tabInstance, (status: boolean, reason?: string) => {
          if (reason) {
            output(reason);
            return;
          }
          output(status);
      });
      } 
    });

Running in local

To be able to finally build, deploy and side load the app in Teams you need to

1. Install dependencies
2. Run the code in local
3. Create a tunnel to the localhost using ngrok
4. Update the manifest file to point to newly started ngrok server.
5. Bundle the manifest with icons
6. Sideload the bundle to Teams.

Pre requisites

• Microsoft Teams is installed and you have an account

• ngrok or equivalent tunnelling solution

ngrok setup

# Install homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install ngrok
brew install ngrok/ngrok/ngrok

# Signup on ngrok website to get an auth token
# Then Setup ngrok in your machine
ngrok config add-authtoken <token>

Install nvm, node, npm, webpack

NOTE: Add -g in case you want these installation to happen across your system and not just in this project scope.

# Install nvm
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

# Install Node
$ nvm install node

# Install npm
$ nvm install-latest-npm

#Install Express
$ npm install express

# Install webpack
$ npm install --save-dev webpack 

Install dependencies

$ cd microsoft-teams-test-tab 
$ yarn link

Run the code in local

# Start server
$ npm run start

Debugger attached.

> microsoft-teams-test-tab@1.0.0 start
> node server.js

Debugger attached.
Listening on http://localhost:3000

Create a tunnel to the localhost using ngrok

1. Open a new terminal window and
2. Start ngrok and preserve the url

$ ngrok http --host-header=rewrite 3000

Update the manifest file to point to newly started ngrok server.

Under Package. manifest.json Temporarily Replace url https://teams-test-tab.azurewebsites.net with ngrok url (https://{uuid}.ngrok-free.app )

Bundle the manifest with icons

• Select manifest.json, color.png, outline.png
• create a zip file

Sideload the bundle to Teams.

• Sideload this zip file into Teams.
• From App tray select "Teams Test Tab"

Contribute

You can now push the changes and eventually create a PR for main project.

• Ensure that you remove the temporary changes made to manifest.json before pushing your module.
• Ensure that only app.ts is modified at the time of push. You will need to add the html files and the *.js and *.js.map files that are rteferenced from the html files
