Welcome to the world of Google Chat apps! In this article, we’ll demystify the process of developing apps for Google Chat, making it user-friendly for you to understand and implement. This guide will cover different programming languages you can use, sample applications, and important integration points. Let’s dive in!

Understanding the Structure of the Code Samples

• The code samples for developing Google Chat apps are organized by language and platform.
• Java and Python sample apps are typically found in their respective folders.
• JavaScript has several implementations, including client-side, server-side with Node.js, Google Apps Script, and Cloud Functions.

Choosing the Right JavaScript Platform

Your choice of platform in JavaScript depends on the type of app you intend to build:

• Google Apps Script: Best for apps that require tighter integration with Google Workspace data.
• Google Cloud Functions: Ideal for apps looking to leverage Google Cloud Platform services and APIs.
• Mobile Apps: Mobile web apps are generally more inclined to use Cloud Functions for Firebase.

Code Sample Overview: Building Your First App

In each directory, you’ll find language-specific implementations, including the following sample applications:

• Basic App: Designed to receive event announcements and respond synchronously with simple text. It serves as an HTTP endpoint app built on Google App Engine.
• Basic Async App: Similar to the basic app, but this one responds asynchronously in the same thread that triggered the event. This, too, is an HTTP endpoint app on Google App Engine.
• PubSub App: Utilizes Google Cloud PubSub to receive messages and respond asynchronously to Google Chat.
• Card App: Offers synchronized responses in a card format, enhancing user experience by formatting interactions creatively. It is also built on Google App Engine.
• Vote App: Empowers users to vote on topics by updating interactive cards—great for casual decision-making at work!

An Analogy to Clarify Sample Applications

Imagine you’re running a restaurant, and your ‘apps’ are different types of meals you could serve. Your basic app is like your signature dish everyone loves—a simple yet satisfying option. The basic async app is akin to a meal served with a side of sauce that you can add to taste as you eat. The PubSub app functions as the chef’s special, cooked on demand, ensuring it arrives at your table just when you need it. The card app is a beautifully plated dish, enhancing the presentation of the flavors, while the vote app is like a buffet where customers can select their favorite dish based on what others suggest. Each app offers its unique flavor, just like the meals at your restaurant!

Troubleshooting Tips

As you embark on developing your own Google Chat apps, you may encounter some hiccups. Here are a few troubleshooting ideas:

• Ensure you have a Google Workspace account; developer access is not available with an @gmail.com email.
• If you run into issues setting up your development environment, consult the README file included in each sample for step-by-step guidance.
• Double-check your implementation of the APIs; poorly structured code can lead to unexpected behavior.
• If the app isn’t responding as expected, verify that you are receiving the correct event notifications from Google Chat.
