React Vite deployed to Vercel But showing white page?

Posted on

Don’t worry, friend! You’re not alone in this frustrating situation. Many developers have faced this issue, and it’s more common than you think. In this article, we’ll dive into the possible reasons behind this problem and provide you with step-by-step solutions to get your React Vite app up and running on Vercel in no time!

What’s happening behind the scenes?

Before we dive into the solutions, let’s understand what might be causing this issue. When you deploy your React Vite app to Vercel, it’s possible that:

  • There’s a configuration issue with your Vite setup.
  • Vercel is not properly configured to serve your React app.
  • There’s a plugin or dependency conflict in your project.
  • Something went wrong during the deployment process.

Troubleshooting steps

Let’s get started with the troubleshooting process! Follow these steps to identify and fix the issue:

Step 1: Verify your Vite configuration

Open your `vite.config.js` file and ensure that it’s properly configured. Make sure you have the correct settings for your React app:

import { defineConfig } from 'vite';
import reactRefresh from '@vitejs/plugin-react-refresh';

export default defineConfig({
  plugins: [reactRefresh()],
  build: {
    outDir: 'build',
  },
});

In this example, we’re using the `reactRefresh` plugin to enable React Fast Refresh. If you’re using a different configuration, adjust it accordingly.

Step 2: Check your Vercel configuration

Log in to your Vercel dashboard and ensure that your project is properly configured. Check the following settings:

  • Build Command: Make sure it’s set to `npm run build` or the command that builds your React app.
  • Output Directory: Verify that it’s set to the correct directory where your build files are generated (e.g., `build` or `dist`).
  • Index Document: Ensure that it’s set to the correct file (e.g., `index.html`).

If you’re using a custom configuration, review it carefully to ensure that it’s correct.

Step 3: Review your package.json file

Open your `package.json` file and check the following:

  • `scripts` section: Verify that your build script is correct and points to the correct command (e.g., `vite build` or `npm run build`).
  • `dependencies` and `devDependencies` sections: Ensure that you have the correct versions of `vite`, `react`, and other dependencies.

If you find any issues, update your `package.json` file accordingly.

Step 4: Check for plugin conflicts

Sometimes, plugin conflicts can cause issues with your React Vite app. Review your `vite.config.js` file and check if you have any conflicting plugins:

import { defineConfig } from 'vite';
import reactRefresh from '@vitejs/plugin-react-refresh';
import vitePluginReact from '@vitejs/plugin-react';

export default defineConfig({
  plugins: [reactRefresh(), vitePluginReact()],
  build: {
    outDir: 'build',
  },
});

In this example, we’re using both `reactRefresh` and `vitePluginReact`. Remove or adjust plugins as needed to resolve any conflicts.

Step 5: Verify your React app

Open your React app’s `index.js` or `App.js` file and ensure that it’s correctly configured. Check for any syntax errors or incorrect imports:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

If you find any issues, update your React app code accordingly.

Step 6: Check the Vercel deployment logs

Log in to your Vercel dashboard and check the deployment logs for any errors or warnings. You can do this by:

  1. Clicking on the deployment in question.
  2. Scrolling down to the “Logs” section.
  3. Reviewing the logs for any error messages or warnings.

If you find any issues, update your configuration or code accordingly.

Solutions to common issues

Here are some common issues you might encounter and their solutions:

Issue: Vite build fails

Solution:

  • Check your `vite.config.js` file for any syntax errors.
  • Verify that your `package.json` file has the correct versions of `vite` and other dependencies.
  • Try running `vite build` locally to identify any issues.

Issue: Vercel deployment fails

Solution:

  • Check your Vercel configuration for any syntax errors.
  • Verify that your build command is correct and points to the correct directory.
  • Try re-deploying your app to Vercel.

Issue: White page after deployment

Solution:

  • Check your React app’s `index.html` file for any syntax errors.
  • Verify that your React app is correctly configured and importing the correct components.
  • Try checking the browser console for any error messages.

Conclusion

By following these troubleshooting steps and solutions, you should be able to identify and fix the issue causing your React Vite app to show a white page after deployment to Vercel. Remember to double-check your configuration, dependencies, and code to ensure that everything is correct.

If you’re still facing issues, feel free to reach out to the Vercel or Vite communities for further assistance.

Troubleshooting Step Possible Solution
Verify Vite configuration Check `vite.config.js` for syntax errors
Check Vercel configuration Verify build command, output directory, and index document
Review package.json file Check `scripts` section and dependencies
Check for plugin conflicts Review `vite.config.js` for conflicting plugins
Verify React app Check `index.js` or `App.js` for syntax errors
Check Vercel deployment logs Review logs for error messages or warnings

Remember, troubleshooting is an iterative process. Be patient, and don’t be afraid to try different solutions until you find the one that works for you!

Frequently Asked Question

If you’re experiencing a white page after deploying your React app to Vercel using Vite, don’t worry, we’ve got you covered! Here are some frequently asked questions to help you troubleshoot the issue.

Q1: Is my Vite configuration correct?

Double-check your `vite.config.js` file to ensure that it’s configured correctly. Make sure you’ve specified the correct build output directory and that your React app is being served from the correct location.

Q2: Are my environment variables set correctly?

Verify that your environment variables are set correctly in your Vercel deployment settings. Specifically, check that your `NODE_ENV` variable is set to `production` and that your API keys or other sensitive information are not exposed.

Q3: Have I optimized my images and assets?

Ensure that your images and assets are properly optimized for web use. Unoptimized assets can cause your app to fail to load, resulting in a white page. Use tools like ImageOptim or TinyPNG to compress your images.

Q4: Is my React app correctly routed?

Verify that your React app’s routing is correctly configured. Make sure that your routes are defined correctly and that your app is rendering the correct component for the requested URL.

Q5: Have I checked the Vercel deployment logs?

Review the Vercel deployment logs to identify any errors or issues that may be causing the white page. This can help you pinpoint the root cause of the problem and take corrective action.
