How to Fix the Blank Page While Deploying Your Project on Vercel

Are you tired of staring at a blank page after deploying your project on Vercel? You’re not alone! Many developers have faced this frustrating issue, but fear not, dear reader, for we’re about to embark on a journey to solve this problem once and for all.

Understanding the Issue

Before we dive into the solution, let’s take a step back and understand what might be causing this issue. When you deploy your project on Vercel, it’s likely that your application is not configured correctly, leading to a blank page. This can be due to a variety of reasons, including:

• Misconfigured environment variables
• Incorrectly set up routing
• Missing or incorrect dependencies
• Invalid HTML or CSS code
• Incompatible browser or device

Step 1: Check Your Environment Variables

One of the most common causes of a blank page is misconfigured environment variables. To fix this, follow these steps:

1. Login to your Vercel dashboard and navigate to your project settings
2. Click on the “Environment Variables” tab
3. Verify that all required environment variables are set correctly
4. Check for any typos or incorrect values
5. Save your changes and redeploy your project

Common Environment Variables to Check

Variable	Description
NODE_ENV	Node.js environment variable, set to “production” for production environments
BASE_URL	Base URL of your application, used for routing and API calls
API_KEY	API key for external services, such as authentication or payment gateways

Step 2: Review Your Routing Configuration

Another common cause of a blank page is incorrectly set up routing. To fix this, follow these steps:

1. Review your routing configuration in your project’s code
2. Verify that all routes are correctly defined and configured
3. Check for any typos or incorrect route names
4. Save your changes and redeploy your project

Popular Routing Libraries to Check

• React Router
• Next.js
• Express.js
• Gatsby

Step 3: Verify Your Dependencies

Missing or incorrect dependencies can also cause a blank page. To fix this, follow these steps:

1. Review your project’s dependencies in your package.json file
2. Verify that all required dependencies are installed and up-to-date
3. Check for any typos or incorrect dependency versions
4. Run npm install or yarn install to reinstall dependencies
5. Save your changes and redeploy your project

Common Dependencies to Check

• React
• React Dom
• Webpack
• Babel

Step 4: Inspect Your HTML and CSS Code

Invalid HTML or CSS code can also cause a blank page. To fix this, follow these steps:

1. Review your HTML and CSS code for any syntax errors
2. Verify that all HTML elements are correctly closed and nested
3. Check for any CSS styling issues, such as invalid selectors or properties
4. Use the browser’s developer tools to inspect your code and identify any errors
5. Save your changes and redeploy your project

Common HTML and CSS Issues to Check

• Unclosed HTML tags, such as <div> without a corresponding </div>
• Invalid CSS selectors, such as .class:invalid
• Missing or incorrect CSS properties, such as display: none;

Step 5: Test on Different Browsers and Devices

Finally, it’s possible that the blank page is due to an incompatible browser or device. To fix this, follow these steps:

1. Test your application on different browsers, such as Google Chrome, Mozilla Firefox, and Microsoft Edge
2. Test your application on different devices, such as desktop, laptop, tablet, and mobile
3. Verify that your application works correctly on each browser and device
4. Identify and fix any browser-specific or device-specific issues

Common Browser and Device Issues to Check

• Internet Explorer compatibility issues
• Mobile device responsiveness issues, such as incorrect layouts or touch events
• Buggy browser extensions or add-ons
