# Development Server Failing to Start with Multiple Linting Errors

[kunal-10-cloud]

Problem Description

The npm run dev command fails to start the development server properly. Vite hangs during startup and doesn't display the typical server URL or startup messages. Additionally, multiple ESLint errors are preventing a proper development workflow.

🔍 Current Behavior

• Running npm run dev shows no output or hangs indefinitely
• Vite configuration loads but the server doesn't start
• Multiple ESLint errors and warnings in the codebase
• Development workflow is blocked

🎯 Expected Behavior

• npm run dev should start the development server successfully
• Vite should display startup messages with local server URL
• No ESLint errors should be present
• Development server should be accessible at http://localhost:5173

📋 Error Details

# ESLint errors (35+ errors, 3 warnings):
- 'require' is not defined in tailwind.config.js
- '__dirname' is not defined in vite.config.js
- 'process' is not defined in vite.config.js
- Duplicate React imports in Home.jsx
- Import statements not at top level in Navbar.jsx
- Undefined variables in RecipeCard.jsx
- Multiple unused variable warnings

🔍 Root Cause Analysis

1. ES Module Configuration Issues: Tailwind config using require() in ES module environment
2. Vite Configuration Problems: Using Node.js globals not available in ES modules
3. React Import Conflicts: Duplicate imports and incorrect placement
4. Missing Dependencies: tailwindcss-animate not properly installed
5. Conflicting Packages: @tailwindcss/vite conflicting with traditional setup

📝 Steps to Reproduce

1. Clone the repository
2. Run npm install
3. Run npm run dev
4. Observe that server doesn't start or show proper output
5. Run npm run lint to see ESLint errors

📎 Additional Context

This issue prevents developers from running the application locally and blocks the development workflow. The fix involves updating configuration files to use proper ES module syntax and resolving code quality issues.
