Building Your First Todo App with Rork: A Step-by-Step Tutorial

Learning to build mobile applications doesn't have to be overwhelming. With Rork, you can create a fully functional Todo app in minutes without needing extensive coding experience. This tutorial will guide you through every step of the process.

What You'll Build

By the end of this tutorial, you'll have a complete Todo application that allows you to:

• Create new tasks
• Mark tasks as complete
• Delete tasks
• Persist data across sessions
• Deploy to mobile platforms

Prerequisites

Before starting, make sure you have:

• Rork Max installed on your system
• A text editor or IDE
• Basic familiarity with mobile app concepts
• 30-60 minutes of your time

Step 1: Initialize Your Rork Project

Let's start by creating a new Rork project. Open your terminal and run:

rork create todo-app
cd todo-app

Rork will scaffold a new project with all the essential files. Your project structure will include:

• /src - Where your app code lives
• rork.config.js - Project configuration
• package.json - Dependencies

Next, install the required dependencies:

npm install

This installs React Native, Rork components, and other necessary libraries.

Step 2: Design Your UI with Rork Prompts

One of Rork's superpowers is generating UI components through natural language prompts. Let's create a beautiful todo app interface by telling Rork exactly what we want.

Open the Rork UI builder and use this prompt:

Create a clean todo app interface with:
- A header showing "My Tasks"
- An input field to add new tasks
- A submit button labeled "Add Task"
- A list displaying all tasks
- Each task should have a checkbox to mark complete
- Each task should have a delete button (trash icon)
- Use a light blue color scheme with rounded corners
- Add some padding and spacing for a modern look

Rork will generate a beautiful, responsive UI component automatically. You can preview it instantly and make adjustments using follow-up prompts:

Make the task items have a subtle shadow and add a smooth animation when tasks are added

The generated component will be placed in your /src/components directory.

Step 3: Add CRUD Functionality

Now let's make your app functional. You'll handle four essential operations:

Create (Add Tasks)

First, set up state management. Ask Rork to create a task service:

Create a task management service that:
- Stores tasks in an array with unique IDs
- Each task has: id, title, completed status, and timestamp
- Has functions to add, get, update, and delete tasks
- Uses AsyncStorage for persistence
- Exports functions: addTask, getAllTasks, updateTask, deleteTask

Read (Display Tasks)

Rork will generate a component that displays your tasks. Use this prompt:

Create a task list component that:
- Fetches all tasks when it mounts
- Displays tasks in order (incomplete first, then complete)
- Shows the number of remaining tasks
- Refreshes when tasks are updated
- Handles empty state with a friendly message

Update (Mark Complete)

Handle task completion:

Create a function that:
- Toggles a task's completed status
- Updates the visual appearance (strikethrough text for completed tasks)
- Updates the data in AsyncStorage
- Animates the transition smoothly

Delete (Remove Tasks)

Finally, add the ability to delete tasks:

Create a delete function that:
- Removes a task by ID
- Shows a confirmation dialog before deletion
- Updates the task list immediately
- Removes the task from AsyncStorage

Step 4: Style Your Application

Let's make your todo app visually appealing. Use Rork's styling prompt:

Apply professional styling to the todo app:
- Use a gradient background from light blue to white
- Color completed tasks with a subtle gray tone
- Add a floating action button for adding tasks
- Use clear typography hierarchy
- Make buttons have hover effects and smooth transitions
- Ensure everything is responsive and works on different screen sizes

You can adjust colors and styling by providing feedback:

Change the primary blue to a teal color and make the task boxes slightly larger

Step 5: Test Your Application

Before deployment, let's ensure everything works correctly. Run:

npm run dev

This starts the development server. Test each feature:

1. Add a task - Type something and press "Add Task"
2. Complete a task - Click the checkbox next to a task
3. Delete a task - Click the delete button
4. Reload the app - Verify tasks persist (thanks to AsyncStorage)
5. Try empty state - Delete all tasks and check the UI

Use Rork's testing feature by asking:

Create unit tests for the todo app that verify:
- Adding a task increases the task count
- Completing a task updates its status
- Deleting a task removes it from the list
- Tasks persist after app restart

Step 6: Deploy Your App

Once you're happy with your todo app, it's time to deploy. Rork supports multiple platforms.

For iOS:

rork build ios
rork deploy ios

For Android:

rork build android
rork deploy android

Ask Rork for guidance on your target platform:

Walk me through deploying this todo app to iOS TestFlight so I can share it with beta testers

Rork will provide platform-specific instructions and handle the complex build configuration automatically.

Tips for Success

• Start simple - Add features incrementally rather than all at once
• Use descriptive prompts - The more detail you provide to Rork, the better the results
• Test frequently - Don't wait until the end to test functionality
• Ask for help - Rork can debug issues and optimize performance
• Iterate - Use feedback to refine your app design and functionality

Next Steps

Congratulations! You've built your first mobile app with Rork. Now that you understand the basics, you can:

• Add categories to organize tasks better
• Implement due dates and reminders
• Create priority levels for tasks
• Add collaboration features so users can share task lists
• Build dark mode support
• Add notifications for task reminders

The beauty of Rork is that each enhancement follows the same pattern: describe what you want, Rork builds it, you test it.

Wrapping up

Building a Todo app with Rork demonstrates the power of AI-assisted development. What might take weeks with traditional development took only hours. You've learned how to:

• Create and configure a Rork project
• Design UIs using natural language
• Implement CRUD operations
• Style applications professionally
• Test and deploy to mobile platforms

Rork makes mobile app development accessible to everyone, regardless of coding experience. Your todo app is now running on real devices and ready to use!

Happy building with Rork!
