🚀 Quick Start with HTTPS

Method 1: Start HTTPS Server Directly

  1. Open Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
  2. Run "Live Server Lite: Start HTTPS Server"
  3. Extension automatically generates SSL certificates using node-forge
  4. Your site opens at https://localhost:3443 🔒
  5. Accept browser security warning (expected for self-signed certificates)

Method 2: Toggle HTTPS Mode

  1. Run "Live Server Lite: Toggle HTTPS/HTTP"
  2. Select "🛡️ HTTPS (Secure)" from the dropdown
  3. Start the server normally - it will use HTTPS protocol

Method 3: Enable HTTPS in Settings

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

🛡️ Certificate Management

Automatic Certificate Generation

  • Live Server Lite automatically creates self-signed certificates
  • Perfect for development and testing secure contexts
  • No manual setup required - works out of the box!

Custom Certificates

{
  "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:

  1. Chrome/Edge:

    • Click "Advanced"
    • Click "Proceed to localhost (unsafe)"
    • Browser remembers this choice for the session
  2. Firefox:

    • Click "Advanced"
    • Click "Accept the Risk and Continue"
  3. 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
}

Test secure API endpoints and cross-origin requests.

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:

  1. 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
    
  2. Setup local Certificate Authority:

    # Install local CA (one-time setup)
    mkcert -install
    
    # This creates a local CA trusted by your browser
    
  3. 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)
    
  4. Configure Live Server Lite:

    {
      "liveServerLite.https": true,
      "liveServerLite.https.certPath": "./localhost+2.pem",
      "liveServerLite.https.keyPath": "./localhost+2-key.pem",
      "liveServerLite.https.autoGenerateCert": false
    }
    
  5. Start server: No more browser warnings! 🎉

Custom Domain Development

Test with custom domains like myapp.localhost:

  1. 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
    
  2. Generate domain certificates:

    # Generate certificates for custom domains
    mkcert myapp.localhost "*.myapp.localhost"
    
  3. 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"
    }
    
  4. 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!

❓ FAQ & Troubleshooting

🔧 Common Issues

Q: "Port already in use" error

A: The default port (5500) is being used by another application.

Solutions:

  1. Automatic: Live Server Lite will try the next available port (5501, 5502, etc.)
  2. Manual: Change the port in settings:
    {
      "liveServerLite.port": 3000
    }
    
  3. Find conflicting process:
    • Windows: netstat -ano | findstr :5500
    • macOS/Linux: lsof -i :5500

Q: Browser shows HTTPS security warnings

A: This is normal and expected when using self-signed certificates for development.

Solutions:

  1. Accept the warning: Click "Advanced" → "Proceed to localhost" (this is safe for development)
  2. Use HTTP for basic development: Set "liveServerLite.https": false
  3. Disable warnings for development: Add browser arguments:
    {
      "liveServerLite.browserArgs": [
        "--ignore-certificate-errors",
        "--ignore-ssl-errors",
        "--disable-web-security"
      ]
    }
    
  4. Custom certificates: Use your own trusted certificates:
    {
      "liveServerLite.https.certPath": "./ssl/cert.pem",
      "liveServerLite.https.keyPath": "./ssl/key.pem",
      "liveServerLite.https.autoGenerateCert": false
    }
    

Q: HTTPS server fails to start

A: Certificate generation or server binding issues.

Solutions:

  1. Check port availability: Try a different HTTPS port:
    {
      "liveServerLite.https.port": 8443
    }
    
  2. Certificate generation failed: Regenerate certificates using:
    • Command: Live Server Lite: Generate SSL Certificate
    • Or restart VS Code to reset certificate cache
  3. Permission issues: Ensure VS Code has write access to workspace
  4. Fallback to HTTP: Extension automatically falls back to HTTP if HTTPS fails
  5. Clear certificate cache: Delete .vscode/certificates folder in workspace

Q: Mixed content warnings in HTTPS

A: Loading HTTP resources from HTTPS pages causes security warnings.

Solutions:

  1. Use relative URLs: src="./script.js" instead of src="http://..."
  2. Protocol-relative URLs: src="//cdn.example.com/lib.js"
  3. Update resource URLs: Change HTTP URLs to HTTPS
  4. Configure build tools: Update webpack/parcel to use HTTPS URLs
  5. Development mode: Use --disable-web-security browser flag (development only)

Q: Service workers not working in development

A: Service workers require HTTPS or localhost for registration.

Solutions:

  1. Enable HTTPS:
    {
      "liveServerLite.https": true
    }
    
  2. Use localhost: Ensure you're accessing via https://localhost:PORT
  3. Accept certificate: Click through browser security warnings
  4. Check console: Look for service worker registration errors
  5. Clear browser cache: Hard refresh with Ctrl+Shift+R

Q: Custom domain certificates not working

A: Certificate domain doesn't match the access URL.

Solutions:

  1. Generate certificate for correct domain:
    {
      "liveServerLite.https.domain": "myapp.localhost"
    }
    
  2. Update hosts file (requires admin privileges):
    # Add to /etc/hosts (macOS/Linux) or C:\Windows\System32\drivers\etc\hosts (Windows)
    127.0.0.1 myapp.localhost
    
  3. Access via correct URL: Use https://myapp.localhost:3443
  4. Regenerate certificate: Run Live Server Lite: Generate SSL Certificate

Q: "File permission denied" errors

A: The extension can't access certain files or directories.

Solutions:

  1. Check VS Code permissions: Ensure VS Code has file system access
  2. Workspace permissions: Verify you have read/write access to project folder
  3. Exclude restricted folders:
    {
      "liveServerLite.ignoreFiles": [
        "node_modules/**",
        ".git/**",
        "**/restricted/**"
      ]
    }
    
  4. Run as administrator (Windows) or sudo (macOS/Linux) if necessary

Q: Live reload not working

A: Browser isn't receiving WebSocket updates.

Solutions:

  1. Check WebSocket connection: Open browser DevTools → Network → WS tab
  2. Firewall settings: Allow VS Code and the port through firewall
  3. Browser compatibility: Ensure WebSocket support (all modern browsers)
  4. Restart server: Stop and start Live Server Lite
  5. Manual refresh: Use Ctrl+F5 / Cmd+F5 for hard refresh

Q: Network access not working from other devices

A: Other devices can't reach your development server.

Solutions:

  1. Check network settings:
    {
      "liveServerLite.host": "0.0.0.0",
      "liveServerLite.useNetworkInterface": true
    }
    
  2. Firewall configuration: Allow the port through your system firewall
  3. Network connectivity: Ensure devices are on the same network
  4. IP address: Use the network IP shown in VS Code status bar
  5. Router settings: Check if router blocks inter-device communication

Q: Memory warning notifications - are they annoying?

A: No! v1.1.0 introduced smart memory warnings that respect your workflow.

Smart Warning Behavior:

  • Only warns when server is running - No warnings when you're not using Live Server
  • Grace period - Waits 30 seconds after server start before monitoring
  • Smart throttling - Maximum 3 warnings per session with 5-minute cooldowns
  • Auto-reset - Warning system resets when memory normalizes or server stops
  • Higher threshold - 500MB default (vs 200MB before) for fewer false alarms

If you see a warning:

  1. Click "Optimize Settings" for one-click optimization
  2. Click "Restart Extension" to clear memory immediately
  3. Click "Dismiss" to increase warning frequency (learns from your preference)

Disable warnings completely:

{
  "liveServerLite.performance.monitoring": false
}

Q: High CPU usage or slow performance

A: File watching is consuming too many resources.

Solutions:

  1. 🆕 Enable large project optimization (enabled by default):

    {
      "liveServerLite.watcher.largeProjectOptimization": true,
      "liveServerLite.watcher.batchEvents": true,
      "liveServerLite.watcher.batchDelay": 250,
      "liveServerLite.watcher.useNativeWatcher": true
    }
    
  2. Exclude large directories:

    {
      "liveServerLite.ignoreFiles": [
        "node_modules/**",
        "dist/**",
        "build/**",
        "**/*.log",
        "**/cache/**"
      ]
    }
    
  3. Increase debounce delay:

    {
      "liveServerLite.debounceDelay": 1000
    }
    
  4. Close unused files: Reduce VS Code's file watching overhead

  5. Project size: Consider splitting very large projects
