Background windows stopped updating because the reaper suspended contexts
after ContextSuspendAfter and fully reaped them after ContextTTL. Suspended
contexts had to re-run the page init function from scratch on reconnect,
losing the live-updating experience.
Contexts now live until the browser tab closes (beforeunload beacon) or
the server shuts down. The context map grows indefinitely — no background
reaper.
Removes: startReaper, reapOrphanedContexts, suspend/resume logic,
ContextSuspendAfter/ContextTTL config fields, lastSeenAt/suspended
context fields, and all associated tests.
Add 30s keepalive pings to prevent proxy/CDN idle timeouts from killing
SSE connections silently. Track lastSeenAt on each SSE connect attempt
so Datastar's retry signals keep contexts alive through the reaper.
Unify event attribute construction through buildAttrKey() so debounce,
throttle, and window modifiers compose cleanly. OnChange no longer
hardcodes a 200ms debounce — callers opt in explicitly.
Contexts that lose their SSE connection now pass through a suspended
state before being fully reaped. Suspended contexts keep their shell
(ID, route, CSRF token) but free page resources. On reconnect, the
page init function is re-run for a seamless resume. Contexts past
the TTL trigger a client-side reload instead of a silent dead page.
Configurable via ContextSuspendAfter (default 15m) and ContextTTL
(default 1h).
Add window-scoped keydown dispatching with per-key signal and
preventDefault options. Use comma operator instead of semicolons
in generated ternary expressions to produce valid JavaScript.
Flatten DatastarConfig struct into Options (DatastarContent, DatastarPath)
and replace datastarHandlerRegistered bool with sync.Once for thread safety.
Allow users to provide their own Datastar.js script (e.g., Datastar Pro
or custom builds) via Via's Options configuration. Adds DatastarConfig
struct with Content ([]byte) and Path (string) fields.
