๐Ÿ” Live Search

Type to filter PHP stdlib functions server-side. Every keystroke is a round-trip โ€” and nobody shipped a line of search logic to the browser.

data-on:input__throttle.100ms.trailing fires at most once every 100 ms while the user types, and always fires one final time at the end โ€” so the last keystroke is never dropped. No setTimeout written by you.
Server-side filtering is intentional. The query parser, category filter, and result ranking all live in PHP. Swap the hardcoded array for a database query and nothing else changes.
$c->sync() re-renders the view for this tab only โ€” no broadcast, no shared state. Other users' searches are completely isolated.
Signals are injected into the context before the action closure runs. By the time the view callable executes, $query->string() already holds the current input value.
Callable views re-run on every sync, computing fresh results. The client receives rendered HTML via SSE โ€” no JSON payload, no client-side fetch() logic.

โšก Signals

query string TAB ""

Current text in the search box. Injected from the browser before the action closure runs.

category string TAB "all"

Active category filter. Set via ?cat= query param when the user clicks a filter pill.

๐ŸŽฏ Actions

search

Reads optional ?cat= param to override category, then calls $c->sync() to re-render the results block.

๐Ÿ‘ Views

live_search.html.twig

Callable view โ€” re-runs on every sync, filtering the PHP stdlib dataset from current signal values. Only the results block is re-rendered on updates.
