Use when building, debugging, or reviewing react-native-tvos, Expo TV, Amazon Vega/Kepler, or React Native web TV targets where the issue depends on remote input, TV focus, TV packaging, TV hardware, or TV playback constraints. license: MIT

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.

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.

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

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.
