Implement chat monitor for cross-platform keyword detection with shared storage by Copilot · Pull Request #128 · enhancer-app/enhancer

Copilot · 2025-12-31T03:38:39Z

Adds opt-in chat monitoring across Twitch and Kick channels with keyword-based notifications. Users can monitor up to 50 channels and receive real-time alerts when specified keywords appear in chat.

Architecture

Shared Storage

Chat monitor data stored in IndexedDB following PR Refactor shared data architecture and enable cross-platform streamer UI #126 pattern
SharedStorageService class provides typed utility functions for accessing shared storage
Typed methods: getSharedStorageKey<K>(key), updateSharedStorageKey<K>(key, value) with automatic TypeScript inference
Chat monitor configuration stored as chatMonitor key within SharedStorageData
Shared across both Twitch and Kick platforms
Worker API actions: getSharedStorageData, setSharedStorageData
Callback system via onStorageChange() for automatic updates

Background Service

WebSocket IRC connectors for Twitch (TMI) and Kick (Pusher) with automatic reconnection
Keyword matching with case-insensitive detection
Message queue stores last 100 matches
Auto-updates when storage changes via callback system

Settings Integration

Chat monitor settings component in General tab (similar to Watchtime List)
Shared component works across both platforms using SharedStorageService
Toggle, channel list (platform + name), and keyword array
Array field validation enforces 50 channel limit
Real-time updates to background worker on save

UI Components

Monitor button adjacent to settings button on both platforms
Popup menu displays recent matches with highlighted keywords, timestamps, and platform/channel context
Notification badge appears on new matches via background message relay

Background-to-Content Communication

Worker bridge relays background messages to content scripts
Content scripts receive messages via WorkerService.onBackgroundMessage()
Avoids direct chrome.runtime.onMessage usage in page context

Example Usage

User enables monitor in settings:

{
  chatMonitor: {
    enabled: true,
    channels: [
      { platform: "twitch", channel: "xqc" },
      { platform: "kick", channel: "trainwreckstv" }
    ],
    keywords: ["essa", "!drops"]
  }
}

Access via SharedStorageService:

// Get chat monitor data with full typing
const chatMonitor = await sharedStorageService.getSharedStorageKey("chatMonitor");

// Update chat monitor data with type validation
await sharedStorageService.updateSharedStorageKey("chatMonitor", newData);

Background service connects to IRC, detects keywords, sends to content script:

// Background worker
chatMonitorService.start(channels, keywords);

// On match
chrome.runtime.sendMessage({
  action: "chatMonitorPing",
  payload: { 
    platform, 
    channel, 
    username, 
    message, 
    keyword, 
    timestamp
  }
});

// Content script receives via worker bridge
workerService.onBackgroundMessage((message) => {
  if (message.action === "chatMonitorPing") {
    // Show notification
  }
});

Implementation Notes

Feature disabled by default (opt-in)
IRC connections use anonymous authentication (no OAuth required)
Twitch connector sends PING every 60s, Kick every 30s
Exponential backoff for reconnection (max 5 attempts)
Worker API actions: getChatMonitorMatches, clearChatMonitorMatches, getChatMonitorStatus, getSharedStorageData, setSharedStorageData
Storage updates trigger automatic chat monitor refresh via callback system
Background messages relayed through worker bridge to avoid chrome.runtime issues in content scripts
SharedStorageService provides type-safe access pattern matching SettingsService

Original prompt

This section details on the original issue you should resolve

<issue_title>feature: chat monitor</issue_title>
<issue_description>we need to implement a "chat monitor" and it should work like this:

in settings on both platforms we need a component (like the watchtime list) with shared storage. here i can add streamer names and their platforms, for example platform: kick, channel: igorovh (let's set a limit of 50 channels for now)

the whole chat monitor must be opt-in/opt-out (turned off by default)

we need a background script that connects to twitch and kick irc. it should handle error messages if the connection fails.

we also need a keyword list in settings. if someone on the connected chats sends a message containing a keyword (e.g. "essa"), it triggers a ping.

the ping should be sent via our system to transfer events from background to content scripts. we receive the ping on the page (not background) and display it to the user.

create a new component for the ping menu located next to the settings button.</issue_description>

@copilot

dont do it like this, we cant store it in settings, because settings are seperated by platform and it is a shared feature - we have to like create custom component in settings that idk, maybe redirects to extension page and all of this will be here
we also need to create like silent pings, when we've got this scenario: user is watching streamer X then a keyword matches on streamer X then we want to send silent ping, because user sees the chat
i got error that chrome.storage.onChanged.addListener is undefined and i dont like how it is handled
we should create something like shared storage, it is already created in Refactor shared data architecture and enable cross-platform streamer UI #126 can you lookup and take only the shared storage logic from this pull request?

I've addressed all 4 points in commit ddc5429:

Shared storage instead of platform settings - Created ChatMonitorStorageService using the same IndexedDB pattern from PR Refactor shared data architecture and enable cross-platform streamer UI #126. Chat monitor data is now stored in a shared database, not separated by platform.
Silent pings - Background worker tracks active tabs and adds silent: true flag to keyword matches when user is viewing that channel. The flag is included in the chatMonitorPing message payload.
Removed chrome.storage.onChanged - The background worker no longer uses chrome.storage.onChanged.addListener(). Instead, it automatically updates the chat monitor service when setChatMonitorStorageData is called.
Shared storage from PR Refactor shared data architecture and enable cross-platform streamer UI #126 - Adapted the same patterns: ChatMonitorStorageDatabase, ChatMonitorStorageService, handlers, and types following the structure from that PR.

The chat monitor settings are now shown in the General tab (similar to Watchtime List) and work across both Twitch and Kick.

dont do it like this, lets do it as getSharedStorage, and then key chatMonitor

Fixed in 2008585. Now using getSharedStorageData/setSharedStorageData with chatMonitor as a key within SharedStorageData, following the same pattern as PR #126.

+	};
+	getChatMonitorStorageData: {
+		payload: never;
+		response: any; // ChatMonitorStorageData


dont use any

Fixed in 2008585. Replaced all any types with proper types: ChatMonitorKeywordMatch[], Logger, and SharedStorageData.

igorovh · 2026-01-02T04:01:38Z

src/types/shared/worker/worker.types.ts

 export type GetSettingsResponse = PlatformSettings;
 export type UpdateSettingsResponse = { success: true };

+export interface GetChatMonitorMatchesPayload {


make all of the this as SharedStorage and then inside this let it be a chatMonitor

Fixed in 2008585. Created SharedStorageData type with chatMonitor nested inside, following the pattern from PR #126.

igorovh · 2026-01-02T04:02:21Z

src/shared/worker/worker.background.ts

+		const result = await handler.handle(payload);
+
+		// After setting chat monitor storage data, update the chat monitor service
+		if (action === "setChatMonitorStorageData") {


create "webhooks"/"callbacks" system, that when it is refresh it will call callback and then chat monitor logic will know that something changed

Fixed in 2008585. Implemented callback system via SharedStorageService.onStorageChange(). Background worker registers a callback that's automatically invoked when storage changes, eliminating the need to check action names.

igorovh · 2026-01-02T04:03:08Z

src/shared/worker/worker.background.ts

+	private updateTabInfo(tabId: number, url: string) {
+		// Parse URL to detect platform and channel
+		try {
+			const parsedUrl = new URL(url);
+			if (parsedUrl.hostname.includes("twitch.tv")) {
+				const pathParts = parsedUrl.pathname.split("/").filter(Boolean);
+				if (pathParts.length > 0 && pathParts[0] !== "directory" && pathParts[0] !== "videos") {
+					this.currentTabs.set(tabId, {
+						platform: "twitch",
+						channel: pathParts[0],
+					});
+					return;
+				}
+			} else if (parsedUrl.hostname.includes("kick.com")) {
+				const pathParts = parsedUrl.pathname.split("/").filter(Boolean);
+				if (pathParts.length > 0) {
+					this.currentTabs.set(tabId, {
+						platform: "kick",
+						channel: pathParts[0],
+					});
+					return;
+				}
+			}
+		} catch (error) {
+			// Invalid URL, ignore
+		}
+	}


i dont like this, i think the chat monitor module should like be firing event every X seconds and then we will know what tab are active and used

src/shared/worker/chat-monitor/get-chat-monitor-matches.handler.ts

+
+export class GetChatMonitorMatchesHandler extends MessageHandler {
+	constructor(
+		logger: any,


dont use any, we can use Logger type here

Fixed in 2008585. Changed logger parameter type from any to Logger in all chat monitor handlers.

igorovh · 2026-01-02T04:03:56Z

src/shared/worker/chat-monitor-storage/set-chat-monitor-storage-data.handler.ts

+
+export class SetChatMonitorStorageDataHandler extends MessageHandler {
+	constructor(
+		logger: any,


Fixed in 2008585. Handler now uses Logger type instead of any.

+		chrome.runtime.onMessage.addListener((message) => {
+			if (message.action === "chatMonitorPing") {
+				// Show notification or update badge
+				this.showNotificationBadge();
+			}
+		});
+	}


we cannot do this here, content scripts does not have access to chrome.runtime, we need to do it via background bridge (which is already created) i would also like that there be like number of notifcations in the logo

Fixed in 6778295. Added background message relay through worker bridge:

Worker bridge listens for chrome.runtime.onMessage (content script context)

Dispatches enhancer-background-message custom event to page context

Added WorkerService.onBackgroundMessage() for modules to listen

Chat monitor button modules now use worker service instead of chrome.runtime

For the notification count in logo - this will be implemented as part of the module restructuring in the next commit.

maybe move it to the settings-button module and rename this module to navbar-icons-module wdyt, we could also seperate logic in files in this module direcotry for settings and chat monitor

src/shared/components/chat-monitor-settings/chat-monitor-settings.component.tsx

+	const saveData = async (newData: ChatMonitorStorageData) => {
+		setSaving(true);
+		try {
+			// First get the full shared storage
+			const fullStorage = await workerService.send("getSharedStorageData", {});
+			if (fullStorage?.data) {
+				// Update only the chatMonitor portion
+				const updatedStorage: SharedStorageData = {
+					...fullStorage.data,
+					chatMonitor: newData,
+				};
+				await workerService.send("setSharedStorageData", { data: updatedStorage });
+				setData(newData);
+			}
+		} catch (error) {
+			console.error("Failed to save chat monitor data:", error);
+		} finally {
+			setSaving(false);
+		}
+	};


we could create a SharedStorage object like the SettingsService and then create "utils" function that to get this data faster, like getSharedStorageKey('chatMonitor') but it need to be fully typed

Implemented in d8fc45f. Created SharedStorageService with typed utility functions following the SettingsService pattern:

getSharedStorageKey<K>(key) - fully typed key access

updateSharedStorageKey<K>(key, value) - fully typed key updates

Chat monitor settings component now uses:

const data = await sharedStorageService.getSharedStorageKey("chatMonitor"); await sharedStorageService.updateSharedStorageKey("chatMonitor", newData);

TypeScript automatically infers the correct types for each key.
