Common Issues with Port 5173

"Port 5173 is already in use"

This error occurs when another application is already using port 5173. Solutions:

Find and close the application using port 5173
Use a different port:
- Command line: npm run dev -- --port 5174
- In vite.config.js:
```
export default defineConfig({
  server: {
    port: 5174
  }
})
```
On Windows, find and kill the process: netstat -ano | findstr :5173 then taskkill /PID [PID] /F
On Linux/Mac: lsof -i :5173 then kill -9 [PID]

"Hot Module Replacement (HMR) not working"

If changes aren't automatically reflecting in the browser:

Check if your Vite server is running with HMR enabled
Ensure you haven't disabled HMR in your vite.config.js
Check for errors in the browser console
Try restarting the development server
Make sure your file is being processed by Vite (check import paths)

"Cannot access localhost:5173 from other devices"

By default, Vite's development server only listens on localhost:

To make it accessible from other devices: npm run dev -- --host

Or in vite.config.js:

export default defineConfig({
  server: {
    host: '0.0.0.0'
  }
})

Then access it using your computer's IP address: http://YOUR_IP:5173
