Define typed, module-scoped state and wrap useUrlState in a feature-scoped custom hook so unrelated React components share the same URL-synced state. Covers drawer/modal open-state, tab switching, multi-select toggles, reset/defaults semantics, and the…

Use the URL as a form draft store by pairing useUrlState with react-hook-form (or formik). Share one module-scoped defaults object between both libraries; hydrate useForm.defaultValues from urlState; push form changes back into setUrl via RHF subscribe() (NOT…

Reconcile instant local input feedback with URL write throttling. setState updates internal state synchronously (instant re-render); setUrl is throttled and asynchronous (URL catches up on the next tick). Use this skill for text inputs, search boxes, sliders,…

SSR-safe useUrlState in Next.js App Router. Forward searchParams from server pages (awaiting the Promise in Next.js 15+) rather than calling useSearchParams(), decide between useHistory true/false, keep pages prerenderable, and use a Proxy (formerly…

Set up useUrlState for React Router v7 (state-in-url/react-router), React Router v6 (state-in-url/react-router6 — moved here in 6.0.0), and Remix v2 (state-in-url/remix). The hook API is identical across all three; only the import path and per-call…

Use useSharedState (from state-in-url, NOT a framework subpath) as a framework-agnostic cross-component state primitive when URL sync is explicitly NOT wanted. Same module-scoped default-state-identity rule as useUrlState. A lightweight Context.Provider…

Wire mouse, wheel and touch input for react-horizontal-scrolling-menu: onWheel/onScroll are plain (api, event) => void callbacks, while ALL mouse/touch props (onMouseDown, onMouseUp, onMouseMove, onMouseLeave, onTouchStart, onTouchMove, onTouchEnd) are…

Detect and upgrade pre-v8 react-horizontal-scrolling-menu patterns that agents trained on older data still generate: destructured visibleElements/isFirstItemVisible/isLastItemVisible/initComplete (removed v6), Separator items, separatorClassName and…

Recipes composed on the react-horizontal-scrolling-menu public API — NOT props: autoplay (setInterval + scrollNext gated on menuVisible), infinite loop/carousel (clone head/tail + scrollLeft teleport at seams), center on click (scrollToItem 'center'),…

Imperative scrolling for react-horizontal-scrolling-menu: scrollToItem(getItemById(id), behavior, inline, block), scrollNext/scrollPrev, apiRef for controlling the menu from outside (fire methods, never read data), getItemElementById/getItemElementByIndex for…

Build a working react-horizontal-scrolling-menu: install, the mandatory 'react-horizontal-scrolling-menu/dist/styles.css' import, ScrollMenu with a unique itemId per child, arrow components via VisibilityContext with useLeftArrowVisible/useRightArrowVisible,…

Server rendering and testing for react-horizontal-scrolling-menu: the library is client-only ('use client' required in React Server Components, else "createContext is not a function"), SSR first paint is controlled by the useIsVisible defaultValue argument…

Animate react-horizontal-scrolling-menu scrolling and build right-to-left menus: noPolyfill defaults to true since v8, so transitionDuration (default 500), a custom-easing-function transitionBehavior, and per-call ScrollOptions { duration, boundary } on…

Track which react-horizontal-scrolling-menu items are on screen: useIsVisible(itemId | 'first' | 'last', defaultValue), useLeftArrowVisible/useRightArrowVisible, the options prop (ratio, rootMargin, threshold), items.getVisible()/subscribe/unsubscribe, and…

Tag server-side fetches with the x-test-rcrd-id session header so SSR is recorded under the correct Playwright test session. Lead with registerProxyFetch (patch global fetch in the root layout, any runtime) and registerProxyAxios (per-axios-instance…

Set up test-proxy-recorder for any Playwright project. Covers the proxy CLI (test-proxy-recorder <target> --port --dir), package.json scripts for the three-service architecture (UI app → proxy → backend API), playwright.config.ts webServer block pointing to…

Record and replay TanStack Start SSR with test-proxy-recorder. Tag server-side fetches (route loaders, server functions, server routes) with the x-test-rcrd-id session header so parallel replay stays correct. Lead with registerProxyFetch (patch global fetch…

Decide whether a playwright-soak run actually leaked and which threshold to move. Covers expectNoLeak, checkLeaks, LeakFinding, LeakThresholds (nodes, listeners, documents, typingCost, heapRatio, heapNoise), reading the formatSoak log block, and the…

Soak a form field or text input with playwright-soak without the run failing on Chromium's own bookkeeping. Covers calibrateTypingCost, the TypingGesture signature, the typingCost threshold on expectNoLeak, and passing the measured cost to formatSoak. Load…

Write a Playwright memory-leak soak test with playwright-soak. Covers attachCDP, soak({ client, flow, iterations, warmup, sampleEvery }), getPageMetrics, shaping a flow that survives repetition, and the playwright.config.ts a few-hundred-iteration run needs…
