How to Build a Randomized Quiz App in Minutes Using Deplyr and Google Sheets

What is Deplyr?

Deplyr is a low-code/no-code platform that allows rapid app development. It offers:

• Front-end (UI) development
• Back-end actions (code snippets for data interactions)
• AI-assisted code generation
• Seamless integration with popular data sources like Google Sheets and Airtable
• Built-in user authentication for private or public apps

With Deplyr, you can spin up production-ready apps in minutes, customize them extensively, and share them with a single click.

Step 1: Integrate Deplyr with Google Sheets

Connecting Deplyr with Google Sheets is straightforward:

1. Click on the Google Sheets integration button in Deplyr on the Integrations page.
2. Follow the consent flow and authenticate your Google account.

Once connected, Deplyr can read and write to the specified sheet using the sheet ID, eliminating the need to manually handle APIs or complex credentials.

Step 2: Understand the Deplyr App Structure

Every Deplyr app typically comprises two main parts:

1. Frontend (UI): Design and layout elements, including text fields, buttons, forms, etc. You can edit the frontend using simple HTML/JS code or via the AI chat interface.

2. Backend Actions: Code snippets that interact with your data source (e.g., Google Sheets). For instance, actions might read quiz questions from one tab or write a user’s answers to another.

AI Code Builder

Deplyr’s AI can generate most, if not all, of the necessary code:

1. Describe the desired functionality.
2. Let Deplyr’s AI generate the code.
3. Refine the generated code as needed using the built-in AI chat interface.

This feature significantly reduces the time spent writing and debugging code.

Step 3: Create Your Randomized Quiz

In the example featured in the video:

• A Google Sheet contains quiz questions and answers, along with a tab for student answers.
• A prompt is crafted to instruct Deplyr to create the app based on specific requirements.

The Prompt

A well-structured prompt is crucial for optimal results. Here's the prompt used:

Based on the following Google Sheet info, we want to generate a simple quiz app.

Each tab has a header row.

Tab: Quiz Questions
Cols: Question ID, Question, Correct Answer, Wrong Answer 1, Wrong Answer 2, Wrong Answer 3

Tab: Student Answers
Cols: Name, Score, Summary of Answers

Context: “Summary of Answers” can be a lot of text; it should list each Question ID and the corresponding answer on a new line within the cell.

The app should function as follows: Upon starting, the student enters their name. Then, questions are displayed in random order as multiple-choice (options A, B, C, and D), with the correct answer randomly assigned to one of these options. After completing the quiz, the student submits their answers. The app calculates the score and populates the spreadsheet but does not display the score to the student; instead, it thanks them.

Creating the App

In Deplyr's dashboard:

1. Click "Create New App" > "With AI".
2. Name your app.
3. Paste the above prompt.

Deplyr will generate the necessary components:

• Frontend
• Action: getQuizQuestions
• Action: submitQuizAnswers

---

Step 4: Save and Launch

After creating the app with the initial prompt, it's ready to use.
