+# Client
+
+This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 21.0.4.
+
+## Development server
+
+To start a local development server, run:
+
+```bash
+ng serve
+```
+
+Once the server is running, open your browser and navigate to `http://localhost:4200/`. The application will automatically reload whenever you modify any of the source files.
+
+## Code scaffolding
+
+Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
+
+```bash
+ng generate component component-name
+```
+
+For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
+
+```bash
+ng generate --help
+```
+
+## Building
+
+To build the project run:
+
+```bash
+ng build
+```
+
+This will compile your project and store the build artifacts in the `dist/` directory. By default, the production build optimizes your application for performance and speed.
+
+## Running unit tests
+
+To execute unit tests with the [Vitest](https://vitest.dev/) test runner, use the following command:
+
+```bash
+ng test
+```
+
+## Running end-to-end tests
+
+For end-to-end (e2e) testing, run:
+
+```bash
+ng e2e
+```
+
+Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
+
+## Additional Resources
+
+For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.

+# User Stories for P2P Chat Application
+
+> **Reference:** [webrtc.org](https://webrtc.org)
+
+The following user stories describe a peer-to-peer chat and voice application (Discord-like) built with **Electron** and **Angular** (using RxJS and NgRx) with a local SQLite store (via SQL.js). A central server only provides a directory of active rooms and users; all message and audio/video data is exchanged directly between peers (no port forwarding needed). Stories are grouped by role and include acceptance criteria and technical notes.
+
+---
+
+## Regular User
+
+### Search and Join Chat Server
+
+**User Story:** As a Regular User, I want to search for available chat servers (rooms) by name or topic so that I can find and join active communities.
+
+**Acceptance Criteria:**
+- A search input allows queries against the central directory of servers.
+- Matching servers are returned and listed with details (name, current user count, etc.).
+- I can select a server from the list and send a join request.
+- If the server exists and is active, I am connected to that server's peer network.
+- Error is shown if the server is not found or unavailable.
+
+**Technical Notes:**
+- Use Angular's `HttpClient` to call the central REST API (e.g. `GET /servers?search={query}`), which returns an Observable.
+- Use RxJS operators (e.g. `debounceTime`) to handle user input.
+- Use Angular components/forms for the search UI and display results. Use `async` pipe in templates for Observables.
+- Store search results and selected server info in an NgRx store or Angular Signals to manage state and reactively update UI.
+
+---
+
+### Create Chatroom (Become Host)
+
+**User Story:** As a Regular User, I want to create a new chatroom so that I can start my own voice/text server; I should automatically become the room's host.
+
+**Acceptance Criteria:**
+- I can create a named room; the central server registers the new room.
+- I join the newly created room and see myself listed as the host/owner.
+- The host can set an optional password or topic for the room.
+- Other users searching for rooms see this new room available.
+- If I disconnect without others online, the room is removed from the server directory.
+
+**Technical Notes:**
+- Use Angular forms to input room details and NgRx actions to handle creation. Dispatch an action that posts to the central server API (e.g. `POST /servers`) and upon success updates the local store.
+- In the NgRx state, mark the creator as `host: true`. Follow NgRx best practices (immutable state, action-driven updates).
+- No code style notes here beyond following lint rules (e.g. `prefer const`, `no var`, 2-space indent).
+- After creation, initiate the P2P mesh: the host opens listening sockets (WebRTC or TCP sockets) and waits for peers (see "P2P Connectivity" story).
+
+---
+
+### Join Existing Chatroom
+
+**User Story:** As a Regular User, I want to join an existing chatroom so that I can participate in it.
+
+**Acceptance Criteria:**
+- I can select an available room and request to join.
+- The host is notified of my request and (if approved) I connect to the room.
+- If no approval step, I immediately join and synchronize chat history and participants.
+- Upon joining, I receive the current chat history (text and possibly voice stream) from one or more peers.
+
+**Technical Notes:**
+- Use Angular Router or services to handle navigation/joining logic.
+- When joining, use a WebRTC signaling channel (via the central server or direct peer signaling) to exchange ICE candidates (STUN/TURN).
+- Once connected, use WebRTC DataChannels for chat data and Streams for audio/video.
+- On the host side, use NgRx Effects to handle incoming join events and broadcast initial state (messages and user list) to new peer.
+
+---
+
+### Send, Edit, Delete, and React to Messages
+
+**User Story:** As a Regular User, I want to send text messages, and edit or delete my own messages (and react to any message), so that I can communicate effectively and correct mistakes.
+
+**Acceptance Criteria:**
+- I can type and send a chat message, which is immediately delivered to all peers.
+- I can edit or delete any of my own previously sent messages; these edits/deletions update on all peers in real time.
+- I can react (e.g. add emoji) to any message; reactions are displayed next to the message for all users.
+- All message operations (send/edit/delete/react) are performed instantly (optimistic UI) and confirmed or synchronized with peers.
+- Deleted messages are removed from the UI for all users.
+
+**Technical Notes:**
+- Use WebRTC `RTCDataChannel` (via a library like `simple-peer` or native API) for sending JSON-encoded message events between peers. Data channels provide reliable, ordered delivery for text.
+- Maintain a local message store (NgRx store or Signals) that holds all chat messages and reactions. Update the store immutably and broadcast updates to other peers.
+- Persist messages locally using SQL.js: run SQLite in-memory and after significant changes call `db.export()` to save state (or write to a file via Electron). On join, import/export to synchronize history (SQL.js can load an existing `Uint8Array` DB).
+- Implement send/edit/delete/react actions and reducers/effects in NgRx. Ensure all reducers treat state immutably and use NgRx Effects for any asynchronous broadcasts.
+- Follow lint rules for event handlers and functions (`no-unused-vars`, consistent naming).
+
+---
+
+### Voice Chat (Push-to-Talk)
+
+**User Story:** As a Regular User, I want to join a voice channel within the chatroom so that I can talk to other participants (e.g. using push-to-talk or a switch).
+
+**Acceptance Criteria:**
+- I can enable my microphone and connect to the voice channel.
+- Other users hear my voice with low latency, and I hear theirs.
+- Only one person needs to be host; no central server relaying audio.
+- If I mute or leave, others no longer hear me.
+- Voice quality adapts to network (e.g. uses Opus codec).
+
+**Technical Notes:**
+- Use WebRTC MediaStreams for audio: call `navigator.mediaDevices.getUserMedia({ audio: true })` to capture microphone audio. Add this audio track to the peer connection.
+- On receiving side, use a `<audio>` element or Web Audio API to play incoming audio streams.
+- Use an ICE/STUN configuration to establish P2P UDP voice channels. This avoids needing port forwarding.
+- Manage audio tracks in NgRx or a service for mute/unmute state. No messages need SQLite storage.
+- Consider using Electron's `contextIsolation` and secure context for permissions.
+
+---
+
+### Screen Sharing (with Game Capture)
+
+**User Story:** As a Regular User, I want to share my screen or a game window with others so that I can show my gameplay or desktop.
+
+**Acceptance Criteria:**
+- I can start screen sharing (full screen, a window, or browser tab).
+- Other users see a video stream of my screen.
+- Shared video uses hardware-accelerated decoding (GPU) for performance.
+- Sharing a game window is possible (capturing fullscreen games).
+- I can stop sharing and return to voice-only.
+
+**Technical Notes:**
+- Use `navigator.mediaDevices.getDisplayMedia()` to capture the screen or window as a MediaStream. For game capture, Electron's `desktopCapturer` or `getDisplayMedia()` with a game window source can be used.
+- Combine the screen stream with WebRTC peer connections so that peers receive video as part of the call.
+- Configure the WebRTC codec to a hardware-accelerated codec (e.g. VP8/VP9 with GPU decoding) if supported. Electron/Chromium typically handles GPU decode automatically for WebRTC.
+- Ensure to handle multiple video tracks (microphone and screen) in the peer connection.
+- Follow ESLint rules for function naming and spacing in all new components.
+
+---
+
+### Local Chat History (Offline Access)
+
+**User Story:** As a Regular User, I want the chat history to be saved locally in the app's database so that I can scroll through recent messages even after restarting the app or going offline.
+
+**Acceptance Criteria:**
+- All sent/received messages in each room are saved in a local SQLite (via SQL.js) database.
+- When I reopen the app or reconnect to a room, previous messages are loaded from the local DB.
+- The database updates dynamically as new messages arrive or are edited/deleted.
+- The DB file (or exported data) persists between app restarts (using Electron's filesystem).
+
+**Technical Notes:**
+- Initialize sql.js on app startup: load the WASM file (e.g. `sql-wasm.wasm`) by configuring `locateFile` in `initSqlJs`.
+- Create a database (`new SQL.Database()`) to hold tables like `messages` and `users`. Use SQL for durable local storage.
+- On each chat event, insert or update records (`INSERT`/`UPDATE`/`DELETE`). Query the DB to load history.
+- After updates, call `db.export()` and save the byte array to a file in Electron's app data directory. On restart, load that file into SQL.js to restore state.
+- Keep SQL code tidy and run queries through a service or NgRx effect, in line with TypeScript ESLint rules (`no unused vars`, `semicolons`, etc.).
+
+---
+
+## Admin
+
+### Moderate Users
+
+**User Story:** As an Admin (room moderator), I want to remove or ban disruptive users so that I can keep the chatroom safe.
+
+**Acceptance Criteria:**
+- I see a list of all users in the room and can select a user to kick or ban.
+- If I kick a user, that user is immediately disconnected from the room and cannot rejoin unless invited.
+- If I ban a user, their address/user ID is added to a room-specific ban list; they cannot rejoin even if they try.
+- Kicked or banned users cannot send any messages or voice.
+- A record of the action (who was kicked/banned) is logged in the chat (for transparency).
+
+**Technical Notes:**
+- On the Angular UI, display user list in an admin dashboard component. Use NgRx store for active users.
+- When "kick/ban" is invoked, dispatch an NgRx action. An NgRx Effect can broadcast a "force-disconnect" signal to that peer's client.
+- The target client, upon receiving this signal, shows a message and disconnects. The room's peers update their state to remove that user.
+- Maintain a ban list (in local state/SQL.js); on new join attempts check this list to reject banned users.
+- Implementation parallels Discord's model: admins can ban/remove members. Follow lint rules and ensure any admin actions update state immutably.
+
+---
+
+### Moderate Chat Content
+
+**User Story:** As an Admin, I want to delete inappropriate messages (even if sent by others) so that harmful content is removed immediately.
+
+**Acceptance Criteria:**
+- I see a delete option on any message in the chat history.
+- Deleting a message removes it from the view for all participants in real time.
+- Deleted message history is purged from local DB for all users.
+- A placeholder (e.g. "Message deleted") is shown so others know a message was removed (optional).
+
+**Technical Notes:**
+- In the message list component, show a delete button for admins on every message.
+- On deletion, dispatch an action; use an NgRx Effect to broadcast a "delete-message" event on the data channel to all peers.
+- Each peer then removes that message from its NgRx store and local SQL DB.
+- Ensure the deletion logic updates the state immutably and follows ESLint rules (e.g. no empty interfaces, one statement per line).
+
+---
+
+### Manage Chatroom / Server Info
+
+**User Story:** As an Admin, I want to update room settings (name, description, rules) so that I can keep the room information current.
+
+**Acceptance Criteria:**
+- I can change the room's display name, topic, or description.
+- Changes propagate to all users immediately (they see the new name/topic).
+- If the room is private, I can update the password or invite list.
+- All users see an "updated by admin" notification.
+
+**Technical Notes:**
+- Use an Angular form or settings dialog for editing room info. Update NgRx store and broadcast changes to peers.
+- Store room metadata in NgRx; use a dedicated slice for "room settings."
+- On update, send a "update-room-info" message over the data channel. Peers update their local UI accordingly.
+- Persist settings in SQL.js so that if the host restarts, the settings remain.
+
+---
+
+### Assign / Revoke Moderator Role (Optional)
+
+**User Story:** As an Admin, I want to designate other users as moderators or revoke their privileges so that management can be delegated.
+
+**Acceptance Criteria:**
+- I can promote a user to moderator (grant them admin rights) and demote them.
+- Moderators get the same capabilities as Admin for moderation tasks.
+- The UI reflects their moderator status (e.g., a badge).
+- Role changes are synced to all clients.
+
+**Technical Notes:**
+- Add a "roles" field in user state (e.g. `user = { id, name, role }`).
+- Implement an Admin action to change a user's role; broadcast this over the P2P channel.
+- All clients update their NgRx state so that role-based UI (e.g. delete buttons) appear accordingly.
+- Use NgRx to enforce role logic in reducers, following immutability rules.
+
+---
+
+## System
+
+### Automatic Host Reassignment
+
+**User Story:** As a System, I need to automatically elect a new host if the current host leaves so that the room continues operating smoothly.
+
+**Acceptance Criteria:**
+- If the host disconnects unexpectedly, the system selects another participant as the new host.
+- Selection criteria might be: longest connected, lowest ping, or first joined. (Define one policy.)
+- All clients update to mark the new host (e.g. show a host badge).
+- The new host gains any host privileges (can kick/ban, etc.).
+- The central directory is updated if needed (new host can keep room alive).
+
+**Technical Notes:**
+- Implement a leader-election algorithm in the P2P mesh: e.g., use Lamport timestamps or simply choose the next-in-list user.
+- On host disconnect event (detected via data channel/peerconnection `onclose`), dispatch a "host-left" action. An NgRx Effect can determine new host ID and broadcast a "new-host" event.
+- Update NgRx state `hostId` and any UI accordingly. This follows NgRx unidirectional flow and immutability.
+- Ensure any pending room changes (like last chat state) transfer seamlessly. The local SQLite DB is already consistent across peers, so no data is lost.
+
+---
+
+### Peer-to-Peer Connectivity & NAT Traversal
+
+**User Story:** As a System, I want all peers to connect directly (audio/data) without requiring users to configure port forwarding.
+
+**Acceptance Criteria:**
+- Peers automatically discover routes to each other (using STUN/TURN) and establish direct connections.
+- No manual network configuration is needed by users.
+- Voice and data streams work across typical home/office NATs.
+- If a direct path fails, relay via TURN.
+
+**Technical Notes:**
+- Use WebRTC's ICE framework: supply STUN (and optionally TURN) servers in the `RTCPeerConnection` configuration.
+- Exchange ICE candidates via the central server signaling (or existing peer connections).
+- The WebRTC API inherently avoids port forwarding by NAT traversal.
+- If TURN is needed, use a public TURN (or self-hosted) relay. This ensures compliance with "no port forwarding" requirement.
+- Manage connections in NgRx/Services; create Effects to handle ICE candidate events and re-dispatch as needed.
+
+---
+
+### Central Server Directory Endpoints
+
+**User Story:** As a System, I will provide REST endpoints so that clients can search for servers and get lists of active users.
+
+**Acceptance Criteria:**
+- A `GET /servers` endpoint returns current active rooms with metadata (name, user count, host).
+- A `GET /users` endpoint returns currently online users for a room.
+- Clients can `POST /join-request` to signal intent to join (if such a flow is needed).
+- Data is updated in real time as rooms/users come and go (clients may poll or use WebSocket if implemented).
+
+**Technical Notes:**
+- Implement server APIs (e.g., with Node.js/Express) that track room and user registrations in memory or a lightweight DB.
+- The Angular app uses `HttpClient` to call these endpoints.
+- Use RxJS on the frontend to poll or listen (via WebSocket or Server-Sent Events) for updates, updating the NgRx store on arrival.
+- Adhere to API error handling best practices in Angular (interceptors, error messages).
+
+---
+
+### Initiate P2P Signaling
+
+**User Story:** As a System, I need to facilitate the initial WebRTC handshake between peers so that they can establish direct connections.
+
+**Acceptance Criteria:**
+- The host and new peers exchange session descriptions (SDP) and ICE candidates via a signaling channel.
+- Signaling can be done over the existing P2P network or via the central server (just for metadata exchange, not media).
+- Once ICE handshake is complete, direct peer connections are established for chat.
+
+**Technical Notes:**
+- Use the central server or a temporary WebSocket channel for exchanging SDP offers/answers (as per WebRTC spec).
+- Implement an NgRx Effect that listens for signaling messages (e.g. via a WebSocket service) and creates/sets local/remote descriptions on `RTCPeerConnection`.
+- All signaling messages (offer, answer, ICE candidates) should be sent as JSON over a lightweight channel.
+- Once WebRTC `onicecandidate` fires, send each candidate to the peer.
+
+---
+
+### Data Synchronization
+
+**User Story:** As a System, I need to keep each peer's local database in sync so that all users see the same chat history and user list.
+
+**Acceptance Criteria:**
+- When a new user joins, they receive the full current chat history and user list from an existing peer.
+- All peers agree on the same final state for edits/deletions; conflicts (rare) are resolved consistently (e.g. last-write-wins).
+- The local SQL databases converge to the same data for the same room.
+- After reconnections or partitioning, peers resynchronize missing events.
+
+**Technical Notes:**
+- On join, the host (or longest-staying peer) can send a "state dump" (all messages and user list) to the newcomer via the data channel, then replay new events.
+- Use timestamps or message IDs to order events. Ensure RxJS streams or NgRx Effects handle out-of-order gracefully.
+- Persist full chat log and user list in SQLite; on conflict (e.g., duplicate message IDs) merge by timestamp.
+- Leverage NgRx selectors to produce sorted message lists, ensuring UI consistency across clients.
+
+---
+
+## Code Quality Guidelines
+
+> **Note:** All code should follow the project's TypeScript and Angular style guidelines.
+
+The ESLint flat config enforces rules like:
+- `no-var`
+- `prefer-const`
+- 2-space indentation
+- Angular ESLint for templates
+
+Use these lint rules and Prettier formatting (as noted in config) to maintain code quality. Each component, service, and NgRx element should comply with the attached ESLint configuration.
