# React Native TV Best Practices

## Overview

TV-specific review guidance for React Native-backed apps on Apple TV, Android TV, Fire TV, Amazon Vega/Kepler, and web-based TV targets such as Tizen or webOS.

Use this skill only for TV deltas: remote input, focus engines, 10-foot layout, platform packaging, playback/DRM, low-memory TV hardware, and TV accessibility. For ordinary React Native performance or architecture issues, use [react-native-best-practices](../react-native-best-practices/SKILL.md).

## Skill Format

Reference files are grouped by topic prefix:

- `focus-*`: focus engines, focus guides, focus event performance
- `nav-*`: D-pad navigation, Back/Menu behavior, keyboard/search input
- `design-*`: 10-foot typography, layout, color, focus visibility
- `perf-*`: startup, memory, lists, animation, and network constraints on TV hardware
- `video-*`: playback architecture, DRM/protocol selection, debugging
- `a11y-*`: TV accessibility implementation and audit checks
- `setup-*`: stack detection, setup, architecture, cross-platform behavior
- `test-*` and `release-*`: test coverage, E2E, and CI/release workflows

## When to Apply

Apply this skill when the app targets a TV platform and the work involves:

- Focus movement, visible focus, focus restoration, or remote/D-pad input
- TV layout readability, overscan/safe areas, or 10-foot UI density
- TV player controls, manifests, DRM, decoder support, or playback errors
- Performance on low-memory TV hardware, especially with video or large carousels
- TV accessibility with screen readers, captions, focus order, or remote-only interaction
- Platform setup for `react-native-tvos`, Expo TV, Amazon Vega/Kepler, Tizen, or webOS

## Before You Start — Identify the TV Stack

This skill covers several TV stacks. **Detect which one the app targets before flagging setup issues** — demanding `react-native-tvos`, a tvOS Podfile, or an Android TV manifest on a Vega/Kepler or web-based TV app produces false positives.

| Stack                                                 | How to detect                                                                                     | Setup expectations                                                                                                             |
| ----------------------------------------------------- | ------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ |
| **react-native-tvos** (Apple TV, Android TV, Fire TV) | `"react-native": "npm:react-native-tvos@…"` in package.json                                       | tvOS Podfile (`platform :tvos`); Android TV `leanback`/`LEANBACK_LAUNCHER` manifest entries; TV emulator/simulator             |
| **Expo + react-native-tvos**                          | above **plus** `@react-native-tvos/config-tv` in app.json                                         | `EXPO_TV=1` prebuild; `react-native-tvos` version must match the Expo SDK; not all Expo features/libraries are available on TV |
| **Amazon Vega / Kepler**                              | Vega/Kepler SDK & tooling (`@amazon-devices/*` deps, Kepler manifest); **no** `react-native-tvos` | Amazon's Vega/Kepler toolchain — `react-native-tvos`, tvOS Podfile, and Android TV manifest do **not** apply                   |
| **Web-based TV** (Tizen, webOS)                       | web bundler (Rsbuild/webpack) + platform packaging; spatial-nav library                           | Platform SDK packaging; `@noriginmedia/norigin-spatial-navigation` for focus                                                   |

The focus, 10-foot design, performance, accessibility, and player guidance applies across all of these — only the **setup/build** expectations are stack-specific.

## Review Rules

- Resolve the target stack before setup advice.
- Prefer natural focus order and focus guides before imperative focus calls or broad `nextFocus*` maps.
- Treat focus loss, invisible focus, and broken Back/Menu behavior as navigation bugs.
- Check readability, safe areas, and focus states at TV distance before tuning visual details.
- Profile on the weakest supported TV device before reporting performance fixes as complete.
- Separate playback failures by layer: manifest request, DRM license exchange, decoder capability, player state, and React UI controls.

## Priority-Ordered Guidelines

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Focus and D-pad navigation | CRITICAL | `focus-*`, `nav-*` |
| 2 | List, animation, and input performance | CRITICAL | `perf-*` |
| 3 | Playback and DRM failures | HIGH | `video-*` |
| 4 | 10-foot readability and layout | HIGH | `design-*` |
| 5 | TV accessibility | HIGH | `a11y-*` |
| 6 | Stack setup, testing, and release | MEDIUM | `setup-*`, `test-*`, `release-*` |

## Quick Reference

1. Detect the TV stack from package files, manifests, native folders, and platform tooling.
2. Reproduce navigation with the remote or D-pad path, not mouse/touch assumptions.
3. Confirm the focused element is always visible, reachable, and restored after modals/routes.
4. Check playback failures from the network/DRM layer upward before changing React controls.
5. Measure list, animation, memory, and startup work on the weakest supported TV target.

## Security (TV-Specific)

General dependency/input hygiene applies as in any RN app; the TV-specific deltas worth calling out:

- Never embed FairPlay/Widevine/PlayReady keys in client code — treat the license server as the trust boundary and keep DRM tokens server-issued.
