  "liveServerLite.https.certPath": "/path/to/your/cert.pem",
  "liveServerLite.https.keyPath": "/path/to/your/key.pem"
}

Generate New Certificates

Command: "Live Server Lite: Generate SSL Certificate"
Specify custom domain (default: localhost)
View certificate location and update settings

⚙️ HTTPS Configuration

Add these settings to your settings.json for HTTPS customization:

{
  // Enable HTTPS by default
  "liveServerLite.https": true,
  
  // HTTPS-specific settings
  "liveServerLite.https.port": 3443,
  "liveServerLite.https.domain": "localhost",
  "liveServerLite.https.autoGenerateCert": true,
  "liveServerLite.https.warnOnSelfSigned": true,
  "liveServerLite.https.certPath": "",  // Leave empty for auto-generation
  "liveServerLite.https.keyPath": ""    // Leave empty for auto-generation
}

🔧 Handling Browser Security Warnings

When you access https://localhost:3443, browsers will show security warnings like:

Chrome/Edge: "Your connection is not private" with NET::ERR_CERT_AUTHORITY_INVALID
Firefox: "Warning: Potential Security Risk Ahead"
Safari: "This Connection Is Not Private"

This is completely normal and expected for self-signed certificates in development!

How to Proceed Safely:

Chrome/Edge:
- Click "Advanced"
- Click "Proceed to localhost (unsafe)"
- Browser remembers this choice for the session
Firefox:
- Click "Advanced"
- Click "Accept the Risk and Continue"
Safari:
- Click "Show Details"
- Click "Visit this website"
- Confirm "Visit Website"

Pro Tips:

✅ These warnings are safe to ignore for localhost development
✅ The connection is actually encrypted between browser and server
✅ Only the certificate authority is not recognized (self-signed)
✅ Your data remains protected during development

For Production: Use certificates from trusted Certificate Authorities (Let's Encrypt, etc.)

Progressive Web Apps (PWAs)

{
  "liveServerLite.https": true,
  "liveServerLite.https.domain": "localhost"
}

Perfect for testing service workers, push notifications, and offline functionality.

API Development & Testing

{
  "liveServerLite.https": true,
  "liveServerLite.https.port": 3443,
  "liveServerLite.cors": true
}

Custom Domain Testing

{
  "liveServerLite.https": true,
  "liveServerLite.https.domain": "myapp.localhost",
  "liveServerLite.https.port": 443
}

Test with custom domains (requires hosts file modification).

🚨 Security Warnings & Browser Setup

Expected Browser Warnings When using self-signed certificates, browsers will show security warnings. This is normal for development!

Chrome/Edge: Click "Advanced" → "Proceed to localhost (unsafe)" Firefox: Click "Advanced" → "Accept the Risk and Continue"
Safari: Click "Show Details" → "Visit this website"

Disable Warnings (Development Only)

Chrome: Launch with --ignore-certificate-errors-spki-list --ignore-certificate-errors --ignore-ssl-errors-spki-list --ignore-ssl-errors
Add to VS Code settings:

{
  "liveServerLite.browserArgs": [
    "--ignore-certificate-errors",
    "--ignore-ssl-errors"
  ]
}

🔍 HTTPS Troubleshooting

Issue: "Certificate not trusted"

Solution: This is expected for self-signed certificates
Action: Click through browser warning or use custom certificates

Issue: "HTTPS server failed to start"

Solution: Check port availability and certificate paths
Action: Try different port or regenerate certificates

Issue: "Mixed content warnings"

Solution: Ensure all resources (CSS, JS, images) use HTTPS URLs
Action: Use relative URLs or configure your build process

Issue: "Service worker not registering"

Solution: Service workers require HTTPS or localhost
Action: Use HTTPS server instead of HTTP for PWA development

🛠️ Advanced HTTPS Setup

Creating Trusted Local Certificates with mkcert

For a seamless development experience without browser warnings:

Install mkcert:

# macOS (Homebrew)
brew install mkcert

# Windows (Chocolatey)
choco install mkcert

# Windows (Scoop)
scoop bucket add extras
scoop install mkcert

# Linux (Ubuntu/Debian)
sudo apt install mkcert

Setup local Certificate Authority:

# Install local CA (one-time setup)
mkcert -install

# This creates a local CA trusted by your browser

Generate trusted certificates:

# Navigate to your project directory
cd /path/to/your/project

# Generate certificates for localhost
mkcert localhost 127.0.0.1 ::1

# This creates:
# - localhost+2.pem (certificate)
# - localhost+2-key.pem (private key)

Configure Live Server Lite:

{
  "liveServerLite.https": true,
  "liveServerLite.https.certPath": "./localhost+2.pem",
  "liveServerLite.https.keyPath": "./localhost+2-key.pem",
  "liveServerLite.https.autoGenerateCert": false
}

Start server: No more browser warnings! 🎉

Custom Domain Development

Test with custom domains like myapp.localhost:

Update hosts file (requires admin/sudo privileges):

# macOS/Linux
echo "127.0.0.1 myapp.localhost" | sudo tee -a /etc/hosts

# Windows (run as Administrator)
echo 127.0.0.1 myapp.localhost >> C:\Windows\System32\drivers\etc\hosts

Generate domain certificates:

# Generate certificates for custom domains
mkcert myapp.localhost "*.myapp.localhost"

Configure settings:

{
  "liveServerLite.https": true,
  "liveServerLite.https.domain": "myapp.localhost",
  "liveServerLite.https.certPath": "./myapp.localhost+1.pem",
  "liveServerLite.https.keyPath": "./myapp.localhost+1-key.pem"
}

Access your app: Visit https://myapp.localhost:3443 with no warnings!

Alternative: Disable Browser Security (Development Only)

For quick testing without certificate setup:

{
  "liveServerLite.browserArgs": [
    "--ignore-certificate-errors",
    "--ignore-ssl-errors",
    "--disable-web-security",
    "--allow-running-insecure-content"
  ]
}

⚠️ Warning: Only use these flags for development. Never use in production!
