Lab: Final Polish,
Deploy, and Rehearse

If time is short, work top to bottom. Never skip #1 for #3.

With our Enterprise CI/CD pipeline in place, your app is automatically deployed to GitHub Pages when you push to main. This is your final check to verify the live URL.

1. Push your latest code to the main branch. This triggers your GitHub Action pipeline.
2. Go to the Actions tab in your repository. Ensure both your tests/linting jobs and deployment job pass successfully.
3. Fix any pipeline failures. If your build fails because of a security vulnerability or linting error, you must fix it and push again.
4. Open the live URL in an incognito/private window. This tests what a fresh visitor sees, not your cached version.
5. Test every feature from the live URL. Click every button. Submit every form. Load every map layer.

Go through every item. Check them off as you complete each one.

• API keys are working (Sentinel Hub, OpenAI, Mapbox, etc.)
• Test on phone (responsive layout, touch interactions)
• Test on tablet (medium breakpoint, map sizing)
• Test on laptop (Chrome, Firefox, or Safari)
• Remove debug code (console.log, alert, test data)
• Update README.md with project name, description, and usage
• Add a favicon (16x16 or 32x32 PNG in the root folder)
• Set a proper <title> tag (not "Untitled" or "React App")
• All image paths resolve (no broken images, no 404s)
• No hardcoded localhost URLs remaining in the code

Before your final commit, do a search-and-destroy pass through your codebase. Here is what to look for:

// ============================================
// FINAL DEPLOYMENT CLEANUP CHECKLIST
// ============================================

// 1. Set DEBUG flag to false
const DEBUG = false;  // Was: true

// 2. Remove unused console.log() calls
//    Search your project: Ctrl+Shift+F → "console.log"

// 3. Verify all API endpoints are correct
const API_BASE = "https://services.sentinel-hub.com";
// NOT: "http://localhost:3000/api"

// 4. Check all image paths resolve
//    Relative paths: "./images/logo.png"
//    NOT: "C:\\Users\\you\\Desktop\\logo.png"

// 5. Test offline behavior gracefully
if (!navigator.onLine) {
  showMessage("Please check your internet connection.");
}

Lighthouse is a free tool built into Chrome DevTools that audits your app for performance, accessibility, best practices, and SEO. Running it takes 30 seconds and can reveal issues you would otherwise miss.

1. Open your live GitHub Pages URL in Chrome.
2. Press F12 to open DevTools, then click the Lighthouse tab.
3. Select categories: Performance, Accessibility, Best Practices.
4. Click "Analyze page load" and wait ~15 seconds.
5. Review the scores and fix any critical issues (red items).

Your project will be featured on the AS26 Project Showcase page. This is your public portfolio entry: future employers, ISU alumni, and the broader space community will see it.

1. Navigate to the showcase portal link above.
2. Log in with your ISU Google account.
3. Click "Submit Project" and fill in all required fields (see next slide).
4. Review your entry before submitting. You can edit until the deadline.

Fill in every field. Incomplete submissions will lose points. Here is what you need to prepare:

Your YouTube "commercial" should follow a tight Problem → Solution → Demo format. Here is a breakdown:

Recording Tools

• OBS Studio (free, open source): Screen + webcam recording with full control.
• Loom (free tier): One-click screen recording, auto-uploads to the cloud.
• Zoom: Share screen and record locally. Quick and familiar.

Production Tips

• Record in a quiet room. Background noise kills credibility.
• Use a script. Read it aloud twice before recording.
• Show the app doing something. Static screenshots are not a demo.
• Upload as Unlisted on YouTube if you prefer privacy.

You have roughly 60 minutes for rehearsal. Use this structured three-round approach:

What to Rehearse

• Your opening: The first 30 seconds set the tone. Nail it.
• The live demo: Practice the exact click sequence. Have a backup plan if the API is slow.
• Your closing: End with impact, not "um, that's it." Prepare a strong final sentence.

These are the issues that trip students up every year. Check each one now, not tomorrow morning.

Friday, June 19, 2026 is presentation day. Here is the format:

Evaluation Criteria

Take a moment to appreciate how far you have come. Nine days ago, most of you had never touched satellite data or built an AI-powered application.
