Functionality

Pattern Testing Flow

1. User enters regex pattern and optional flags
2. User enters text string to test
3. Click "Test Regex" button
4. Component creates RegExp with pattern and flags
5. Calls .match() on test string
6. Displays results or error message

Error Handling

• Try/catch wrapping regex compilation
• User-friendly error messages
• Error prevents match display

Results Display

• Match count with proper pluralization
• Indexed match items with monospace font
• Sky-blue highlight for match labels
• Scrollable container (max-height: 16rem)

Dependencies

• react (useState hook)
• @/app/components/AdUnit (existing project component)
• tailwindcss (styling)
• TypeScript (type safety)

Code Quality

• Type-safe match results handling
• Proper error boundaries
• Accessible form labels
• Responsive design
• Consistent styling with project theme

Deployment Steps

1. SCP component to target location:

   scp RegexTesterClient.tsx [email protected]:/home/websites1/webtools/src/app/components/tools/
   

2. Create page wrapper in /home/websites1/webtools/src/app/tools/regex-tester/:

   import RegexTesterClient from "@/app/components/tools/RegexTesterClient";
   export default function RegexTesterPage() {
     return <RegexTesterClient />;
   }
   

3. Restart Next.js application on server

Testing Checklist

• Component renders without errors
• Default pattern (\d+) finds numbers in test string
• Test string contains "Hello 123 World 456" by default
• Default flags are "g" (global)
• Results display shows "2 matches"
• Changing pattern updates results in real-time
• Invalid regex patterns show error message
• Ad unit renders properly
• Responsive on mobile/tablet/desktop

Pre-Deployment Notes

• This is the final (8th) task component
• All 8 tasks now have code staged and ready
