General Troubleshooting Steps

Before diving into specific issues, try these general troubleshooting steps:

Clear cache and node_modules

bash rm -rf node_modules npm cache clean --force

Reinstall dependencies

bash npm install

Update Para-related packages

bash npm update @getpara/react-sdk@alpha

Rebuild the project

bash npm run build

Common Issues and Solutions

Missing Node.js Polyfills

Problem: Vite doesn’t include Node.js polyfills by default, which can cause issues with packages that depend on Node.js built-ins like buffer or crypto.

Solution: Add the necessary polyfills using the vite-plugin-node-polyfills plugin. Adjust the configuration as needed for your specific requirements:

Install the plugin:

npm install --save-dev vite-plugin-node-polyfills

Update your vite.config.js:

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import { nodePolyfills } from "vite-plugin-node-polyfills";

export default defineConfig({
  plugins: [
    react(),
    nodePolyfills({
      include: ["buffer", "crypto", "stream", "util"],
    }),
  ],
  // ... other configurations
});

Environment Variables Not Accessible

Problem: Environment variables not being recognized in your application.

Solution: Ensure you’re prefixing your environment variables with VITE_ and accessing them correctly:

In your .env file:
```
VITE_PARA_API_KEY=your_api_key_here
```

In your code:

const para = new Para(Environment.BETA, import.meta.env.VITE_PARA_API_KEY);

CSS Loading Issues

Problem: Para’s CSS files not loading correctly.

Solution: Import Para’s CSS file in your main App.jsx or index.jsx:

import "@getpara/react-sdk/dist/index.css@alpha";

function App() {
  // Your app code
}

export default App;

Best Practices

Use the Latest Versions: Always use the latest versions of Vite, React, and Para SDK to ensure compatibility and access to the latest features.
Error Handling: Implement error boundaries to gracefully handle any runtime errors related to Para integration.
Development vs Production: Use environment-specific configurations to manage different settings for development and production builds. Para provides environment-specific API keys.

By following these troubleshooting steps and best practices, you should be able to resolve most common issues when integrating Para with your React application using Vite.
