Zoom Apps JavaScript Sample

This Zoom App Sample uses Node.js + Express to build a simple Hello World Zoom App.

Prerequisites

1. Node JS
2. Ngrok
3. Zoom Account
4. Zoom App Credentials (Instructions below)
   1. Client ID
   2. Client Secret
   3. Redirect URI

Getting started

Open your terminal:

# Clone down this repository
git clone git@github.com:zoom/zoomapps-sample-js.git

# navigate into the cloned project directory
cd zoomapps-sample-js

# run NPM to install the app dependencies
npm install

# initialize your ngrok session
ngrok http 3000

Create your Zoom App

In your web browser, navigate to Zoom Developer Portal and register/log into your developer account.

Click the "Build App" button at the top and choose to "Zoom Apps" application.

1. Name your app
2. Choose whether to list your app on the marketplace or not
3. Click "Create"

For more information, you can follow this guide check out this video series on how to create and configure these sample Zoom Apps.

Config: App Credentials

In your terminal where you launched ngrok, find the Forwarding value and copy/paste that into the "Home URL" and " Redirect URL for OAuth" fields.

Home URL:               https://xxxxx.ngrok.io
Redirect URL for OAuth: https://xxxxx.ngrok.io/auth

NOTE: ngrok URLs under ngrok's Free plan are ephemeral, meaning they will only live for up to a couple hours at most, and will change every time you reinitialize the application. This will require you to update these fields every time you restart your ngrok service.

OAuth allow list

• https://example.ngrok.io

Domain allow list

• appssdk.zoom.us
• ngrok.io

Config: Information

The following information is required to activate your application:

• Basic Information
  • App name
  • Short description
  • Long description (entering a short message here is fine for now)
• Developer Contact Information
  • Name
  • Email address

NOTE: if you intend to publish your application on the Zoom Apps Marketplace, more information will be required in this section before submitting.

Config: App Features

Under the Zoom App SDK section, click the + Add APIs button and enable the following options from their respective sections:

APIs

• shareApp

Scopes

Ensure that the following scope is selected on the Scopes tab:

• zoomapp:inmeeting

Config .env

When building for Development, open the .env file in your text editor and enter the following information from the App Credentials section you just configured:

# Client ID for your Zoom App
ZM_CLIENT_ID=[app_client_id]

# Client Secret for your Zoom app
ZM_CLIENT_SECRET=[app_client_secret]

# Redirect URI set for your app in the Zoom Marketplace
ZM_REDIRECT_URL=https://[xxxx-xx-xx-xxx-x].ngrok.io/auth

Zoom for Government

If you are a Zoom for Government (ZfG) customer you can use the ZM_HOST variable to change the base URL used for Zoom. This will allow you to adjust to the different Marketplace and API Base URLs used by ZfG customers.

Marketplace URL: marketplace.zoomgov.com

API Base URL: api.zoomgov.com

Start the App

Development

Run the dev npm script to start in development mode using a Docker container.

npm run dev

The dev script will:

1. Watch JS files and built to the dist/ folder
2. Watch Server files and build to the dist/ folder
3. Start the application

Production

When running your application in production no logs are sent to the console by default and the server is not restarted on file changes.

We use the NODE_ENV environment variable here to tell the application to start in prodcution mode.

# Mac/Linux
NODE_ENV=production npm start

# Windows
set NODE_ENV=production && npm start

Usage

To install the Zoom App, Navigate to the Home URL that you set in your browser and click the link to install.

After you authorize the app, Zoom will automatically open the app within the client.

Keeping secrets secret

This application makes use of your Zoom App Client ID and Client Secret as well as a custom secret for signing session cookies. During development, the application will read from the .env file. ;

In order to align with security best practices, this application does not read from the .env file in production mode.

This means you'll want to set environment variables on the hosting platform that you' re using instead of within the .env file. This might include using a secret manager or a CI/CD pipeline.

⚠️ Never commit your .env file to version control: The file likely contains Zoom App Credentials and Session Secrets

Code Style

This project uses prettier and eslint to enforce style and protect against coding errors along with a pre-commit git hook(s) via husky to ensure files pass checks prior to commit.

Testing

At this time there are no e2e or unit tests.
