React 19 standards — TypeScript strict, feature-based components, hooks-first composition, TanStack Query for server state, zustand for cross-tree client state, Suspense + ErrorBoundary at every async boundary, Radix for a11y. Use when writing or reviewing React components, hooks, or client-side state.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# React Architecture
Targets **React 19** with **TypeScript strict**. Component library defaults to Radix primitives + Tailwind (covered deeply in [ui-ux-architect](../../frontend/ui-ux-architect/SKILL.md)). When this skill applies to Next.js apps, server-side concerns live in [nextjs-architect](../nextjs-architect/SKILL.md). See [STACK.md](STACK.md) for pinned dependencies.
## 1. TypeScript posture — strict, always
`tsconfig.json` baseline in [RECIPES.md § `tsconfig.json` — strict baseline](RECIPES.md#tsconfigjson--strict-baseline).
- **No `any`.** Use `unknown` for truly untyped boundaries, then narrow.
- **No type assertions (`as`)** except at validated I/O boundaries (after a Zod parse, etc.).
- **`noUncheckedIndexedAccess`** is on — `arr[0]` is `T | undefined`, you handle the undefined. Catches a whole class of runtime crashes.
- **`exactOptionalPropertyTypes`** distinguishes `{x?: string}` from `{x: string | undefined}`. Pick the right one per use case.
- **Discriminated unions over enum + cast.** `type Status = {kind: "loading"} | {kind: "ok"; data: T} | {kind: "err"; msg: string}`.
## 2. Project structure — feature-based

How to install
mdr add ralvarez-ai/ralvaskills/react-architect@sha256:ea37b6d91534faceThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
