Time to first byte (TTFB) is how long it takes a server to generate HTML of a requested page. 1-2 seconds is an acceptable TTFB of an uncached page. Anything above it could be a sign of a performance issue.
Replaces the stock Knockout/RequireJS checkout with a single Alpine.js component using native REST calls. Supports guest and customer flows, coupons, shipping/payment methods, and T&C, with a tiny footprint, CSP-safe assets, and a per–store view toggle.
Splits one‑page checkout into islands: an instantly typeable, cache‑friendly shell with deferred window.checkoutConfig and the stock Knockout payment component, so existing gateways keep working. Includes Google Places autocomplete, saved‑address carousel via customer‑data/localStorage, guest‑order linking, inline validation, and a fail‑safe fallback. Beta; tested primarily alongside its sibling performance extension, and requires 2.4.6+ with PHP 8.1+.
Extends the dev:tests:run command to execute static, unit, integration, and integrity test suites in parallel via ParaTest, with --processes and --runner options and full --arguments passthrough. Includes Composer install steps and CLI examples for speeding up local and CI pipelines.
