How to Build a Simple Web App with Codeium in 2 Hours

Building a web app can feel daunting, especially if you’re a solo founder or indie hacker juggling multiple responsibilities. You might think you need a team of developers or weeks of work to create something functional. But what if I told you that with the right tools, you can whip up a simple web app in just two hours? In 2026, Codeium is one of those tools that can help you do just that.

Prerequisites: What You Need Before You Start

Before diving into the build, make sure you have the following:

• A Codeium account: Sign up for free at Codeium.com. The free tier offers basic features, which are sufficient for this project.
• Node.js installed: You can download it from nodejs.org. This will allow you to run your web app locally.
• Basic understanding of JavaScript: Familiarity with JavaScript will help you customize your app as you go.

Step 1: Setting Up Your Development Environment

1. Install Codeium: After signing up, follow the instructions to install the Codeium plugin for your code editor (VSCode works great).
2. Create a new project: Open your terminal and run:

   npx create-react-app my-simple-app
   cd my-simple-app
   code .
   

   This sets up a basic React app structure.

Step 2: Using Codeium to Generate Code

1. Open your code editor: With Codeium installed, you can start writing code faster.
2. Generate components: Start creating a simple component. For example, type Create a button component and let Codeium generate the code for you.
3. Edit the generated code: Modify the button text and styles as needed. Codeium provides suggestions based on your input, making it easy to iterate.

Expected Output:

You should see a basic button rendered on your app’s homepage that you can click.

Step 3: Adding Functionality

1. Create a simple API call: Use Codeium again to generate code for fetching data from a public API. For example, type Fetch user data from JSONPlaceholder.
2. Display the data: Modify your component to display the fetched data in a list.

Troubleshooting:

• If your API call fails, check the console for errors. Common issues include CORS or incorrect API endpoints. Codeium can help you debug by generating suggested solutions.

Step 4: Styling Your App

1. Add CSS styles: Use Codeium to generate CSS styles for your components by typing Add styles for the button.
2. Make it responsive: Ask Codeium for suggestions on making your app mobile-friendly.

Step 5: Testing Your App

1. Run your app: Use the command npm start to run your app locally.
2. Test functionalities: Click through your app and make sure everything works as expected.

What Could Go Wrong:

• Dependencies issues: If you encounter errors related to missing packages, run npm install to install any dependencies.

Step 6: Deploying Your App

1. Choose a hosting platform: For beginners, platforms like Vercel or Netlify are great options.
2. Deploy your app: Follow the platform’s instructions to connect your GitHub repo and deploy your app with just a few clicks.

What's Next:

• Now that you have a simple web app, consider adding more features or scaling your app. Explore Codeium’s advanced features for more complex functionalities.
