crash-test

Demonstrates godom's disconnect overlay, disconnect badge, and panic recovery.

Usage

# Root mode — custom overlay (default)
go run .

# Root mode — built-in godom overlay
go run . -default

# Embedded mode — custom badge
go run . -embed

# Embedded mode — built-in godom badge
go run . -embed -default

What to expect

Root mode (full-page overlay)

Three disconnect scenarios:

• Exit button — clean os.Exit(0) after 5s countdown. Shows "Disconnected" overlay with no error message.
• Crash button — panic via godom.call after 5s countdown. The framework catches the panic, sends the error message to the browser, then exits. Overlay shows the panic message.
• Background crash — a 30s countdown runs in a background goroutine and panics when it hits zero. This panic is not recoverable by the framework (Go can't recover panics across goroutines), so the overlay shows "Disconnected" with no error detail.

Embedded mode (per-island badge)

A static HTML page with two godom islands (clock and controls). Kill the server to see disconnect badges appear next to each island.

Customization

By default this example loads custom HTML from ui/partials/:

• disconnect.html — full-page overlay (root mode)
• disconnect-badge.html — per-island badge (embedded mode)

Use -default to see godom's built-in overlay/badge instead.

To customize in your own app:

eng.DisconnectHTML = `<div>Your custom overlay</div>`
eng.DisconnectBadgeHTML = `<div>Your custom badge</div>`

Include an element with class godom-disconnect-error containing a <pre> tag to display crash error messages in the overlay.
