<!-- family-agnostic: per-platform-by-design — this reference IS the per-platform Stream inventory + target-family table; one row per platform by design. -->
# Stream (GetStream) inventory — what to find, and where it goes

Search case-insensitively. Skip `node_modules/`, `Pods/`, `build/`, `.dart_tool/`, `.gradle/` and `.git/`. "Stream" is also a common English word, so match the **package and type names below**, never the bare word `stream`. A package hit tells you Stream is present. The **import/API hits** tell you *what the app does with it*, and each one becomes a ledger row (`file:line → purpose`).

## Target family (where each platform lands)
| App platform (detect `framework`) | Stream packages you'll see | CometChat family (`peers.yaml`) | UI SDK mode → | Client mode (own UI) → |
|---|---|---|---|---|
| React / Next / Vite / CRA / Astro / React Router | `stream-chat-react`, `stream-chat`, `@stream-io/stream-chat-css`, `@stream-io/video-react-sdk` | `react-v7` | `cometchat-react-v7-core` + `-components`/`-placement` | the core's SDK fallback (`@cometchat/chat-sdk-javascript`, docs-map → SDK docs) |
| Angular | `stream-chat-angular`, `stream-chat`, `@ngx-translate/core` (Stream i18n) | `angular-v5` | `cometchat-angular-v5-core` | the core's SDK fallback (JS Chat SDK) |
| React Native / Expo | `stream-chat-react-native`, `stream-chat-expo`, `stream-chat`, `@stream-io/video-react-native-sdk` | `react-native` | `cometchat-react-native-core` | `cometchat-react-native-sdk` |
| iOS (Swift) | SPM `stream-chat-swift` (`StreamChat`, `StreamChatUI`), `stream-chat-swiftui` (`StreamChatSwiftUI`), `stream-video-swift`; pods `StreamChat`, `StreamChatUI`, `StreamChatSwiftUI` | `ios` | `cometchat-ios-core` (UIKit; host SwiftUI screens via a representable) | the iOS core's SDK fallback (`CometChatSDK`) |
| Android | `io.getstream:stream-chat-android-client`, `-offline`, `-state`, `-ui-components` (Views), `-compose`, `io.getstream:stream-video-android-*` | `android-v6` (cohort from `android_variant`: Compose → `compose-*`, Views → `kotlin-*`) | `cometchat-android-v6-core` | `cometchat-android-v5-sdk` |
| Flutter | `stream_chat_flutter`, `stream_chat_flutter_core`, `stream_chat`, `stream_chat_persistence`, `stream_chat_localizations`, `stream_video_flutter` | `flutter-v6` | `cometchat-flutter-v6-core` | the Flutter core's SDK fallback (`cometchat_sdk`, re-exported by the kit) |
| Video only (no chat) | `@stream-io/video-react-sdk`, `@stream-io/video-client`, `@stream-io/video-react-native-sdk`, `stream-video-swift`, `io.getstream:stream-video-android-*`, `stream_video_flutter` | the matching headless calls peer (`js-calls`, `react-native-calls`, `ios-calls`, `android-calls`, `flutter-calls`) | — | `cometchat-js-v5-sdk` / `cometchat-react-native-v5-sdk` / `cometchat-ios-v5-sdk` / `cometchat-android-v5-calls-sdk` / `cometchat-flutter-v5-sdk` |
| Server | `stream-chat` (Node, with the API secret), `@stream-io/node-sdk`, Python `stream-chat`/`getstream`, `stream-chat-go`, `stream-chat-ruby`, `get-stream/stream-chat` (PHP), `io.getstream:stream-chat-java`, `stream-chat-net` | — (REST, no UI Kit) | — | CometChat REST (`/rest-api/…`) |

A platform that isn't in this table (Vue, Svelte, Unity, .NET MAUI…) has no family in this pack → STOP (2): report only.

### React Native is a native platform for the build, not a web one
The migration is not done when Metro bundles: `cd ios && pod install` (the kit's Podfile needs the
`modular_headers` lines the family `-core` lists, or `pod install` itself fails), then BUILD **and
RUN** both platforms. Three failures never appear in CI — only when a person uses the app:

| Trap | What you see |
|---|---|
| React Native >= 0.87 on iOS | the kit's composer calls `InteractionManager`, removed from RN core in 0.87 — tapping send throws (`InteractionManager has been removed from react-native core`); Android is unaffected. Shim: the family `-troubleshooting` |
| a missing native peer | fails at MOUNT, and the error names the peer (`gesture-handler`, `svg`, `video`), never CometChat |
| `tsc --noEmit` | reports errors from inside the kit's own shipped source (it ships raw `src/*.tsx`), so gate on the Metro bundle — see the family `-core` -> Verify it works, which also carries the run recipe for a machine where port 8081 is taken |
