JKVideo is a cross-platform (Android/iOS/Web) Expo React Native application that acts as an unofficial Bilibili client. It browses Bilibili recommendation feeds, searches videos, plays DASH video via a locally generated MPD consumed by react-native-video/ExoPlayer, streams live rooms over HLS, displays video and live danmaku, loads comments, supports QR-code login, downloads videos, and shares them over a LAN HTTP server. The code is organized into expo-router screens, React hooks, Zustand stores, a single API service module, and utility modules; it uses signed WBI requests and maintains Bilibili cookies/CSRF state. The implementation quality is above average for a community project: the service layer includes request deduplication and network-only retries; the video player uses Animated-driven seek bars with video-shot preview thumbnails and quality fallback chains; DASH MPD generation handles Dolby Vision and segment ranges; the download hook pauses on background and resumes on foreground. However, there are no automated tests, some dead/default code remains (App.tsx is not the real entry), a hardcoded Sentry DSN and an exposed EAS Sentry auth token are present, and the LAN-share QR code relies on an external QR API. Live 'real-time' danmaku is actually 1.5-second REST polling of Bilibili's history endpoint, despite README claims of WebSocket. The repository is explicitly deprecated: the Chinese README states Bilibili sent a legal letter and maintenance/Issues/PRs have ceased, even though the last commit is recent. This code is useful as a reference for Bilibili API integration, DASH MPD construction, danmaku rendering, and React Native video-player architecture, but it should not be selected for new production use.
The LLM identified 5 files worth highlighting for reuse:
Pure TypeScript implementation of Bilibili's WBI request signing, including a dependency-free MD5 and the official mixin-key permutation table. It is self-contained and can be lifted directly into any Bilibili API client.
Builds a local MPD file from Bilibili's DASH play info, selecting the requested video track, highest-bandwidth audio, preserving segment_base ranges, escaping XML, and adding Dolby Vision supplemental properties. Directly applicable to any ExoPlayer-based Bilibili client.
Generic hook for a floating draggable panel: distinguishes tap from drag, hit-tests a close region, snaps to left/right screen edges with spring animation, and keeps latest callbacks in a ref to avoid stale closures. Extractable into any React Native app needing a mini-player or floating action button.
A tiny hook that manages the mount, slide-in, slide-out, and unmount lifecycle of a bottom sheet. It ensures the exit animation completes before unmounting the Modal and tolerates interrupted animations without leaving stale UI state.
Parses Bilibili's danmaku XML into typed items, filters unsupported modes, unescapes HTML entities, converts colors, and sorts by timestamp. Small, self-contained, and reusable for any Bilibili danmaku integration.
