Source: https://context7.com/elian-argentics/complexity/llms.txt

Shows how to initialize the i18n module with lazy-loaded translations to optimize bundle size. Includes examples of advanced formatting for dates, numbers (currency), and lists.

```typescript
import { initI18n, dt } from "@complexity/i18n";

// Lazy-load translations
const { t } = await initI18n({
  locale: navigator.language,
  fallbackLocale: ["en-US", "en"],
  translations: {
    en: () => import("./locales/en.json"),
    es: () => import("./locales/es.json"),
    fr: () => import("./locales/fr.json"),
    "zh-cn": () => import("./locales/zh-CN.json")
  }
});

// Date formatting
const dateTranslation = dt("Last login: {date:date}", {
  date: {
    date: {
      year: "numeric",
      month: "long",
      day: "numeric"
    }
  }
});

console.log(t("lastLogin", { date: new Date("2025-01-15") }));
// Output: "Last login: January 15, 2025"

// Number formatting with currency
const priceTranslation = dt("Price: {amount:number}", {
  number: {
    amount: {
      style: "currency",
      currency: "USD"
    }
  }
});

console.log(t("price", { amount: 1299.99 }));
// Output: "Price: $1,299.99"

// List formatting
const listTranslation = dt("Selected: {items:list}", {
  list: {
    items: {
      type: "conjunction",
      style: "long"
    }
  }
});

console.log(t("selected", { items: ["Apple", "Banana", "Orange"] }));

### Monolithic Zustand Store Example

Source: https://github.com/elian-argentics/complexity/blob/nxt/perplexity/extension/docs/articles/refactor/refactoring-zustand-stores.md

Illustrates a single, large Zustand store before refactoring. It combines user, settings, and modal states and actions within one interface and implementation. This serves as the starting point for the refactoring process.

```typescript
// src/features/some-feature/store.ts
import { create } from "zustand";
import { immer } from "zustand/middleware/immer";

interface StoreState {
  // User state
  user: User | null;
  setUser: (user: User) => void;

  // Settings state
  theme: "dark" | "light";
  toggleTheme: () => void;

  // Modal state
  isModalOpen: boolean;
  openModal: () => void;
  closeModal: () => void;
}

export const useFeatureStore = create<StoreState>()(
  immer((set) => ({
    // User implementation
    user: null,
    setUser: (user) => set({ user }),

    // Settings implementation
    theme: "light",
    toggleTheme: () =>
      set((state) => {
        state.theme = state.theme === "light" ? "dark" : "light";
      }),

    // Modal implementation
    isModalOpen: false,
    openModal: () => set({ isModalOpen: true }),
    closeModal: () => set({ isModalOpen: false }),
  })),
);

```

### AudioPlayback Interface Definition

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/weasound/README.md

Defines the general interface for any audio playback subsystem. It includes methods for playing audio, piping audio from a MessagePort, getting the number of channels, accessing underlying audio nodes (shared or unshared), and closing the playback.

```typescript
/**
 * General interface for any audio playback subsystem, user implementable.
 */
abstract class AudioPlayback extends events.EventEmitter {
    /**
     * Play this audio.
     */
    play(data: Float32Array[]): void;

    /**
     * Pipe audio from this message port. Same format as pipe() in
     * AudioCapture.
     */
    pipeFrom(port: MessagePort): void;

    /**
     * Get the underlying number of channels.
     */
    channels(): number;

    /**
     * Get the underlying AudioNode, *if* there is a unique audio node for this
     * playback.
     */
    unsharedNode(): AudioNode | null;

    /**
     * Get the underlying AudioNode, if it's shared.
     */
    sharedNode(): AudioNode | null;

    /**
     * Stop this audio playback and remove any underlying data.
     */
    close(): void;
}

```

### Handle Settings Subscriptions Typescript

Source: https://github.com/elian-argentics/complexity/blob/nxt/perplexity/extension/docs/articles/refactor/refactoring-zustand-stores.md

Implements side effects for the Settings slice using Zustand's subscribe method. This example demonstrates persisting the theme preference to localStorage whenever the theme changes. It requires the FeatureStoreType to be defined.

```typescript
import type { FeatureStoreType } from "../../types";

export const settingsSubscriptions = (store: FeatureStoreType) => {
  store.subscribe(
    (state) => state.theme,
    (theme) => {
      // Side effect: sync theme to localStorage
      console.log("Theme changed to:", theme);
      localStorage.setItem("theme", theme);
    },
  );
};
```

### Background Script CSS Import for HMR

Source: https://github.com/elian-argentics/complexity/blob/nxt/perplexity/extension/docs/hmr.md

Demonstrates the correct way to import CSS files in background scripts to maintain HMR functionality. The example shows that standard imports should be used, avoiding the '?inline' suffix which breaks HMR. It also questions the necessity of importing CSS in background scripts, suggesting a design rethink.

```typescript
// background.ts
import styles from "./some-css-file.css"; // Standard import
```

--------------------------------

### AudioCapture Interface Definition (JavaScript)

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/weasound/README.md

Defines the abstract interface for audio capture subsystems in Weasound. It includes methods for getting sample rate and VAD state, setting VAD state, closing the capture, and piping data to a MessagePort. It also emits 'data' and 'vad' events for audio data and voice activity detection changes, respectively.

```javascript
/**
 * General interface for any audio capture subsystem, user-implementable.
 *
 * Events:
 * * data(Float32Array[]): Audio data event. Each element of the array is a
 *   single channel of audio data.
 * * vad(null): Audio VAD change event. Fired every time the VAD status changes.
 */
abstract class AudioCapture extends events.EventEmitter {
    /**
     * Get the sample rate of this capture. Must never change. Usually *but not
     * always* follows an AudioContext.
     */
    getSampleRate(): number;

    /**
     * Get the current VAD state.
     */
    getVADState(): VADState;

    /**
     * Set the current VAD state. Subclasses may want to block this and do the
     * VAD themselves.
     */
    setVADState(to: VADState);

    /**
     * Stop this audio capture and remove any underlying data.
     */
    close(): void;

    /**
     * Pipe data to this message port, using shared memory if requested (and
     * possible). Message will be either a Float32Array[] (array of channels),
     * or, if using shared memory, a single message of the form
     * {
     *   c: "buffers",
     *   buffers: Float32Array[],
     *   head: Int32Array
     * }
     * In the "buffers" case, the buffers are a shared memory buffer, and head
     * is a write head into each buffer. The writer will update the head with
     * each write, using the buffers as ring buffers. The receiver must be fast
     * enough to read the buffers before the ring wraps around.
     */
    pipe(to: MessagePort, shared = false);
}

### JavaScript Audio Capture and Playback with LibAV Resampling

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/weasound/demo/loopback/loopback.html

This JavaScript code snippet initializes audio capture using Weasound and `navigator.mediaDevices.getUserMedia`. It then sets up an audio playback node and a LibAV filter graph for resampling audio. The `capture.on('data', ...)` callback processes incoming audio data, resamples it using LibAV, and plays it back, logging estimated latency.

```javascript
LibAV = { base: "../../node_modules/libav.js/dist" };
async function go() {
  const ms = await navigator.mediaDevices.getUserMedia({
    audio: {
      echoCancellation: false,
    },
  });
  const ac = new AudioContext();
  const capMethodBox = document.getElementById("cap-method");
  const capMethod = capMethodBox.value;
  const playMethodBox = document.getElementById("play-method");
  const playMethod = playMethodBox.value;

  // Create a capture
  const capture = await Weasound.createAudioCapture(ac, ms, {
    demandedType: capMethod,
  });

  // Create a playback
  const playback = await Weasound.createAudioPlayback(ac, {
    demandedType: playMethod,
  });

  (playback.unsharedNode() || playback.sharedNode()).connect(
    ac.destination,
  );

  // Create the resampler
  const libav = await LibAV.LibAV({ noworker: true });
  const frame = await libav.av_frame_alloc();
  const [filter_graph, buffersrc_ctx, buffersink_ctx] = await libav.ff_init_filter_graph(
    "aresample",
    {
      sample_rate: capture.getSampleRate(),
      sample_fmt: libav.AV_SAMPLE_FMT_FLT,
      channel_layout: 4,
    },
    {
      sample_rate: ac.sampleRate,
      sample_fmt: libav.AV_SAMPLE_FMT_FLT,
      channel_layout: 4,
    },
  );

  // And pipe the data thru
  capture.on("data", async (data) => {
    const filterFrames = await libav.ff_filter_multi(
      buffersrc_ctx,
      buffersink_ctx,
      frame,
      [
        {
          data: data[0],
          channel_layout: 4,
          format: libav.AV_SAMPLE_FMT_FLT,
          sample_rate: capture.getSampleRate(),
        },
      ],
    );

    for (const frame of filterFrames) {
      const latencyIn = capture.getLatency();
      const latencyOut = playback.play([frame.data]);
      console.log(
        `Estimated latency: ${latencyIn} in + ${latencyOut} out`,
      );
    }
  });
}
```

### Weasound: Create and Manage Browser Audio Playback (TypeScript)

Source: https://context7.com/elian-argentics/complexity/llms.txt

This snippet demonstrates how to play raw PCM audio using the Weasound library. It covers creating an AudioContext, initializing the playback instance with optional preferred types, connecting the audio node to the system's output, generating and playing a test tone, queuing multiple audio chunks, and piping audio data from a Web Worker. Dependencies include the '@complexity/weasound' library and the `AudioContext` API.

```typescript
import { createAudioPlayback } from "@complexity/weasound";

const audioContext = new AudioContext({ sampleRate: 48000 });

// Create playback instance
const playback = await createAudioPlayback(audioContext, {
  // preferredType: "awp"  // Optional: force specific type
});

console.log(`Channels: ${playback.channels()}`);

// Connect audio node to output
const node = playback.unsharedNode() || playback.sharedNode();
if (node) {
  node.connect(audioContext.destination);
}

// Generate and play test tone (440 Hz sine wave)
const sampleRate = audioContext.sampleRate;
const duration = 1.0; // seconds
const frequency = 440; // Hz
const samples = Math.floor(sampleRate * duration);

const audioData = [new Float32Array(samples)]; // Mono audio

for (let i = 0; i < samples; i++) {
  audioData[0][i] = Math.sin(2 * Math.PI * frequency * i / sampleRate) * 0.3;
}

// Play audio (sample-perfect queueing)
playback.play(audioData);

// Queue multiple audio chunks seamlessly
setTimeout(() => {
  // Play another chunk (will start immediately after first finishes)
  playback.play(audioData);
}, 100);

// Pipe from Web Worker
const worker = new Worker("audio-generator.js");
const channel = new MessageChannel();
playback.pipeFrom(channel.port1);
worker.postMessage({ port: channel.port2 }, [channel.port2]);

// Worker sends: port.postMessage([leftChannel, rightChannel])

// Clean up
setTimeout(() => {
  playback.close();
  audioContext.close();
}, 5000);

### JavaScript Audio Playback with LibAV.js and Weasound

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/weasound/demo/playback/playback.html

This JavaScript code demonstrates how to decode an audio file using LibAV.js and play it back using the Weasound library. It initializes LibAV, opens the selected audio file, decodes its audio stream, applies filtering for format and sample rate conversion, and then plays the audio frames using Weasound's AudioPlayback. It handles potential errors like missing audio tracks and manages playback latency.

```javascript
const Playback demo LibAV = { base: "../../node_modules/libav.js/dist" };
async function go() {
  const fileBox = document.getElementById("file");
  if (!fileBox.files.length) return;
  const file = fileBox.files[0];
  const methodBox = document.getElementById("method");
  const method = methodBox.value;

  // Create a playback
  const ac = new AudioContext();
  const playback = await Weasound.createAudioPlayback(ac, {
    demandedType: method,
  });
  (playback.unsharedNode() || playback.sharedNode()).connect(
    ac.destination,
  );

  const libav = await LibAV.LibAV();
  let filter_graph = -1, buffersrc_ctx, buffersink_ctx;

  // Open the file
  await libav.mkreadaheadfile("in", file);
  const [fmt_ctx, streams] = await libav.ff_init_demuxer_file("in");

  let streamIdx = -1;
  for (let i = 0; i < streams.length; i++) {
    if (streams[i].codec_type === libav.AVMEDIA_TYPE_AUDIO) {
      streamIdx = i;
      break;
    }
  }
  if (streamIdx < 0) {
    alert("Could not find audio track");
    return;
  }
  const stream = streams[streamIdx];

  // Open the decoder
  const [, c, pkt, frame] = await libav.ff_init_decoder(
    streams[streamIdx].codec_id,
    streams[streamIdx].codecpar,
  );

  // Decode and play
  while (true) {
    const [res, packets] = await libav.ff_read_multi(fmt_ctx, pkt, null, { limit: 1 });
    if (!packets || !packets[streamIdx]) continue;

    // Decode them
    const frames = await libav.ff_decode_multi(
      c,
      pkt,
      frame,
      packets[streamIdx],
    );
    if (!frames.length) continue;

    // Filter them to get the correct format and framerate
    if (filter_graph < 0) {
      [filter_graph, buffersrc_ctx, buffersink_ctx] = await libav.ff_init_filter_graph(
        "aresample",
        {
          sample_rate: frames[0].sample_rate,
          sample_fmt: frames[0].format,
          channel_layout: frames[0].channel_layout,
        },
        {
          sample_rate: ac.sampleRate,
          sample_fmt: libav.AV_SAMPLE_FMT_FLT,
          channel_layout: 4,
        },
      );
    }

    const filterFrames = await libav.ff_filter_multi(
      buffersrc_ctx,
      buffersink_ctx,
      frame,
      frames,
    );

    for (const frame of filterFrames) {
      const latency = playback.play([frame.data]);
      console.log(`Estimated latency: ${latency}`);
      // Don't get too far ahead!
      if (latency > 200) await new Promise((res) => setTimeout(res, 100));
    }

    if (res === 0 || res === libav.AVERROR_EOF) break;
  }
}
```

### Load All Dependencies with AsyncDependencyRegistry in TypeScript

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/async-dep-manager/README.md

Shows how to load all registered dependencies simultaneously using the `loadAll` method of AsyncDependencyRegistry. The result is a typed object containing all available dependencies.

```typescript
const allDeps = await asyncDependencyRegistry.loadAll();
// allDeps contains all loaded dependencies with proper types
const { myConfig, myService, myConstant, myUtil } = allDeps;
```

--------------------------------

### Create Audio Capture (JavaScript)

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/weasound/README.md

Asynchronously creates an audio capture object using the provided AudioContext and MediaStream or AudioNode. This function selects the most appropriate capture mechanism for the browser. It requires an initialized AudioContext and returns a Promise that resolves to an AudioCapture instance.

```javascript
/**
 * Create an appropriate audio capture from an AudioContext and a MediaStream.
 * @param ac  The AudioContext for the nodes.
 * @param ms  The MediaStream or AudioNode from which to create a capture.
 */
export async function createAudioCapture(
    ac: AudioContext, ms: MediaStream | AudioNode,
    opts: AudioCaptureOptions = {} 
): Promise<AudioCapture>;
```

### AsyncDependencyRegistry: Create and Configure Registry (TypeScript)

Source: https://context7.com/elian-argentics/complexity/llms.txt

Demonstrates the creation and configuration of a type-safe distributed dependency registry using AsyncDependencyRegistry. It covers registering dependencies, handling prerequisites, loading dependencies individually or all at once, and accessing them synchronously. This pattern is useful for managing complex application states and asynchronous operations.

```typescript
// registry.ts
import { AsyncDependencyRegistry } from "@complexity/async-dep-registry";
import { DependencyRegistry } from "@complexity/async-dep-registry.types";

// Define your registry interface
export interface AppRegistry extends DependencyRegistry {
  config: { apiKey: string; endpoint: string };
  database: { query: (sql: string) => Promise<any> };
  auth: { login: (user: string) => Promise<boolean> };
}

// Create a singleton registry instance
export function createRegistry() {
  return AsyncDependencyRegistry.create<AppRegistry>({
    verbose: true,  // Enable detailed logging
    auto: false     // Manual dependency loading
  });
}

const registry = createRegistry();

// Register dependencies with automatic type inference
registry.register({
  id: "config",
  dependencies: [],
  loader: () => ({
    apiKey: process.env.API_KEY || "default",
    endpoint: "https://api.example.com"
  })
});

registry.register({
  id: "database",
  dependencies: ["config"],
  loader: async (deps) => ({
    query: async (sql: string) => {
      console.log(`Querying ${deps.config.endpoint}: ${sql}`);
      return { rows: [] };
    }
  })
});

registry.register({
  id: "auth",
  dependencies: ["config", "database"],
  loader: async (deps) => ({
    login: async (user: string) => {
      await deps.database.query(`SELECT * FROM users WHERE name='${user}'`);
      return true;
    }
  })
});

// Load single dependency with prerequisites
const auth = await registry.load("auth");
await auth.login("john");

// Load all dependencies in optimal parallel order
const allDeps = await registry.loadAll();
console.log(allDeps.config, allDeps.database, allDeps.auth);

// Synchronous access after loading
const config = registry.getSync("config");
console.log(config.apiKey);

// Performance analysis
registry.summary();

```

### Weasound: Create and Manage Browser Audio Capture (TypeScript)

Source: https://context7.com/elian-argentics/complexity/llms.txt

This snippet demonstrates how to create and manage audio capture from the browser's microphone using the Weasound library. It includes requesting microphone access, setting up an AudioContext, initializing the capture with automatic technology selection, listening for audio data events, handling Voice Activity Detection (VAD), and piping data to a Web Worker for efficient processing. Dependencies include the '@complexity/weasound' library and browser APIs like `navigator.mediaDevices.getUserMedia` and `AudioContext`.

```typescript
import { createAudioCapture } from "@complexity/weasound";

// Request microphone access
const stream = await navigator.mediaDevices.getUserMedia({
  audio: {
    echoCancellation: true,
    noiseSuppression: true,
    autoGainControl: true
  }
});

// Create audio context
const audioContext = new AudioContext({ sampleRate: 48000 });

// Create capture (automatically selects best available method)
const capture = await createAudioCapture(audioContext, stream, {
  // Optional: force specific capture type
  // preferredType: "awp"  // awp, mstp, mr, mropus, sp
});

console.log(`Sample rate: ${capture.getSampleRate()} Hz`);
console.log(`Latency: ${capture.getLatency()} ms`);

// Listen for audio data (Float32Array per channel)
capture.on("data", (audioData) => {
  // audioData is Float32Array[] - one array per channel
  console.log(`Received ${audioData.length} channels`);
  console.log(`Samples per channel: ${audioData[0].length}`);

  // Process audio data
  for (let channel = 0; channel < audioData.length; channel++) {
    const samples = audioData[channel];
    // Calculate RMS level for visualization
    const rms = Math.sqrt(

Source: https://github.com/elian-argentics/complexity/blob/nxt/perplexity/extension/docs/articles/refactor/refactoring-zustand-stores.md

Creates the Settings slice using Zustand's StateCreator. It initializes the theme to 'light' and provides a toggleTheme function to switch between 'dark' and 'light' modes. This slice also re-exports settings subscriptions.

```typescript
import type { StateCreator } from "zustand";
import type { FeatureStoreType } from "../../types";
import type { SettingsSlice } from "./types";

export const createSettingsSlice: StateCreator<
  FeatureStoreType,
  [],
  [],
  SettingsSlice
> = (set) => ({
  theme: "light",
  toggleTheme: () =>
    set((state) => {
      state.theme = state.theme === "light" ? "dark" : "light";
    }),
});

// Re-export subscriptions for easy import in the main index
export { settingsSubscriptions } from "./subs";
```

### BrowserRuntimeAdapter: Cross-Context Communication in Browser Extensions

Source: https://context7.com/elian-argentics/complexity/llms.txt

Enables communication between different parts of a browser extension (background scripts, content scripts, popup pages) using a pub/sub pattern. It handles message passing and asynchronous responses. Dependencies include `@comctx-adapters/core` and `comctx`.

```typescript
import { BrowserRuntimeAdapter } from "@comctx-adapters/core";
import { Context } from "comctx";

// Background script (service worker)
const bgContext = new Context("background", new BrowserRuntimeAdapter());

bgContext.on("getData", async (message, meta) => {
  console.log(`Request from tab ${meta.sender.tabId}, frame ${meta.sender.frameId}`);

  // Perform background work
  const data = await fetch("https://api.example.com/data");
  return data.json();
});

bgContext.on("updateBadge", (count) => {
  chrome.action.setBadgeText({ text: String(count) });
});

// Content script
const contentContext = new Context("content", new BrowserRuntimeAdapter());

async function fetchData() {
  try {
    const result = await contentContext.send("getData", { query: "test" });
    console.log("Received from background:", result);
    return result;
  } catch (error) {
    console.error("Failed to communicate:", error);
  }
}

// Send message without waiting for response
contentContext.send("updateBadge", 5);

// Listen for messages from background
contentContext.on("notification", (message) => {
  console.log("Background sent notification:", message);

  // Display in-page notification
  const div = document.createElement("div");
  div.textContent = message.text;
  document.body.appendChild(div);
});

// Popup script
const popupContext = new Context("popup", new BrowserRuntimeAdapter());

document.getElementById("btn").addEventListener("click", async () => {
  const data = await popupContext.send("getData", {});
  displayData(data);
});
```

### AudioCapture Interface

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/weasound/README.md

The general interface for any audio capture subsystem, including methods for sample rate, VAD state, closing the capture, and piping data.

```APIDOC
## AudioCapture Interface

### Description
The AudioCapture interface represents a general audio capture subsystem. It provides methods for accessing capture properties, managing voice activity detection (VAD), and handling audio data output.

### Methods
- **getSampleRate()**: Returns the sample rate of the capture.
- **getVADState()**: Returns the current Voice Activity Detection state.
- **setVADState(to: VADState)**: Sets the current Voice Activity Detection state. Subclasses may override this.
- **close()**: Stops the audio capture and releases resources.
- **pipe(to: MessagePort, shared = false)**: Pipes audio data to a MessagePort. Supports shared memory for performance.

### Events
- **data(Float32Array[])**: Fired when new audio data is available. Each element in the array represents a single channel.
- **vad(null)**: Fired when the VAD status changes.

### Usage Example (Data Event)
```javascript
audioCapture.on('data', (channelData) => {
  console.log('Received audio data:', channelData);
});
```

### Usage Example (Piping with Shared Memory)
```javascript
const messageChannel = new MessageChannel();
audioCapture.pipe(messageChannel.port1, true);
messageChannel.port2.onmessage = (event) => {
  if (event.data.c === 'buffers') {
    console.log('Received shared audio buffers:', event.data.buffers);
    console.log('Current head position:', event.data.head);
  }
};
```
```

### JavaScript Audio Playback with Weasound

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/weasound/demo/tone/tone.html

This JavaScript code creates and controls audio playback using the Weasound library. It initializes an AudioContext, allows selection of playback types (e.g., Shared ScriptProcessor, AudioWorkletProcessor), and plays audio frames with dynamic sample generation. It also estimates and logs playback latency, providing a mechanism to avoid falling too far behind.

```javascript
let ac, playback, playbackType, workers;
async function go() {
    const btn = document.getElementById("go");
    btn.onclick = void 0;
    const methodBox = document.getElementById("method");
    const method = methodBox.value;

    // Create a playback
    if (!ac) ac = new AudioContext();
    if (!playback || playbackType !== method) {
        playbackType = method;
        playback = await Weasound.createAudioPlayback(ac, {
            demandedType: method,
        });
        (playback.unsharedNode() || playback.sharedNode()).connect(ac.destination);
    }

    let stop = false;
    btn.innerText = "Stop";
    btn.onclick = () => {
        stop = true;
        btn.innerText = "Play";
        btn.onclick = go;
    };

    // Play
    let si = 0;
    while (!stop) {
        // Create a frame
        const samples = new Float32Array(
            Math.floor(Math.random() * 1000) + 100
        );
        for (let i = 0; i < samples.length; i++) {
            samples[i] = Math.sin((si / ac.sampleRate) * 600 * Math.PI);
            si++;
        }

        const latency = playback.play([samples]);
        console.log(`Estimated latency: ${latency}`);

        // Don't get too far ahead!
        if (latency > 200) await new Promise((res) => setTimeout(res, 100));
    }
}

// Playback type: Default Shared AudioWorkletProcessor Shared ScriptProcessor AudioBuffers Private AudioWorkletProcessor Private ScriptProcessor
document.getElementById("go").onclick = go;
```

### Slice-based Zustand Store: Assembling Slices

Source: https://github.com/elian-argentics/complexity/blob/nxt/perplexity/extension/docs/articles/refactor/refactoring-zustand-stores.md

Demonstrates how to create a slice-based Zustand store by assembling individual slice functions. It utilizes middleware like `immer` and `subscribeWithSelector` for optimized state management and subscriptions. The `createWithEqualityFn` is used for efficient store updates.

```typescript
// src/plugins/some-feature/store/index.ts
import { subscribeWithSelector } from "zustand/middleware";
import { immer } from "zustand/middleware/immer";
import { createWithEqualityFn } from "zustand/traditional";

import { createModalSlice } from "./slices/modal";
import { createSettingsSlice, settingsSubscriptions } from "./slices/settings";
import { createUserSlice } from "./slices/user";
import type { FeatureStoreType } from "./types";

export const featureStore = createWithEqualityFn<FeatureStoreType>()(
  subscribeWithSelector(
    immer((set, get, ...props) => ({
      ...createUserSlice(set, get, ...props),
      ...createSettingsSlice(set, get, ...props),
      ...createModalSlice(set, get, ...props),
    })),
  ),
);

// Initialize any centralized subscriptions
(() => {
  settingsSubscriptions(featureStore);
})();

export const useFeatureStore = featureStore;

```

### Load Multiple Dependencies with AsyncDependencyRegistry in TypeScript

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/async-dep-manager/README.md

Explains how to use `loadMultiple` to ensure several specified dependencies, along with their prerequisites, are loaded into the AsyncDependencyRegistry. This is useful for pre-loading necessary components.

```typescript
await asyncDependencyRegistry.loadMultiple(["myConfig", "myService"]);
// This ensures that 'myConfig' and 'myService' (and their prerequisites) are loaded.
// You can then access them individually using `load` if needed, or rely on them being available for other dependencies.

```

--------------------------------

### AsyncDependencyRegistry: Modular Registration Pattern (TypeScript)

Source: https://context7.com/elian-argentics/complexity/llms.txt

Illustrates a modular registration pattern for AsyncDependencyRegistry, allowing dependency definitions to be spread across different files and feature modules. It uses TypeScript's module augmentation to extend the main registry interface, enabling a scalable and organized approach to managing dependencies in larger applications.

```typescript
// features/analytics.ts
import { createRegistry } from "./registry";

// Extend registry interface in feature file
declare module "./registry" {
  interface AppRegistry {
    analytics: { track: (event: string) => void };
  }
}

const registry = createRegistry();

registry.register({
  id: "analytics",
  dependencies: ["config"],
  loader: (deps) => ({
    track: (event: string) => {
      console.log(`[${deps.config.endpoint}] Event: ${event}`);
    }
  })
});

// features/notifications.ts
import { createRegistry } from "./registry";

declare module "./registry" {
  interface AppRegistry {
    notifications: { send: (msg: string) => Promise<void> };
  }
}

const registry = createRegistry();

registry.register({
  id: "notifications",
  dependencies: ["config", "analytics"],
  loader: async (deps) => ({
    send: async (msg: string) => {
      deps.analytics.track("notification_sent");
      console.log(`Sending: ${msg}`);
    }
  })
});

// app.ts - Import all features
import "./features/analytics";
import "./features/notifications";
import { createRegistry } from "./registry";

async function main() {
  const registry = createRegistry();

  // Load specific dependency (auto-loads prerequisites)
  const notif = await registry.load("notifications");
  await notif.send("Hello World");

  // Or load everything
  await registry.loadMultiple(["analytics", "notifications"]);
}

```

--------------------------------

### Load Single Dependency with AsyncDependencyRegistry in TypeScript

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/async-dep-manager/README.md

Demonstrates the process of loading a single dependency using the `load` method of AsyncDependencyRegistry. The loaded dependency is fully typed based on the application's registry definition.

```typescript
const myService = await asyncDependencyRegistry.load("myService");
// myService is fully typed based on YourAppRegistry definition
const data = await myService.getData();
```

--------------------------------

### New Query Key Definition Pattern (TypeScript)

Source: https://github.com/elian-argentics/complexity/blob/nxt/perplexity/extension/docs/articles/refactor/drop-@lukemorales-query-key-factory/index.md

This snippet illustrates the new pattern for defining query keys, emphasizing the use of `as const` for literal type inference and `queryOptions` for query configuration. This pattern aims to improve type safety and reduce the need for manual type assertions.

```typescript
export const queries = {
  all: () => ["scope"] as const,
  endpoint: {
    all: () => [...queries.all(), "endpoint"] as const,
    detail: (params) =>
      queryOptions({
        queryKey: [...queries.endpoint.all(), params],
        queryFn: () => fetchData(params),
      }),
  },
};
```

--------------------------------

### Create Multiple AsyncDependencyRegistry Instances in TypeScript

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/async-dep-manager/README.md

Illustrates how to create distinct instances of AsyncDependencyRegistry for different application subsystems. Each instance manages its dependencies independently, allowing for isolated scopes and configurable options like verbosity.

```typescript
// Create separate dependency managers for different subsystems
const authAsyncDependencyRegistry = AsyncDependencyRegistry.create<AuthRegistry>({
  verbose: true,
});

const dataAsyncDependencyRegistry = AsyncDependencyRegistry.create<DataRegistry>({
  verbose: false,
});

// Each instance manages its own dependencies independently

```

### Initialize and Use Translations with @complexity/i18n

Source: https://context7.com/elian-argentics/complexity/llms.txt

Demonstrates how to initialize the i18n module with static translations and use the 't' function for type-safe access to translated strings. Supports parameter substitution, pluralization, enum substitution, and nested key paths.

```typescript
import { initI18n, dt } from "@complexity/i18n";

// Define base translations
const enTranslations = {
  greeting: "Hello, {name}!",
  items: dt("You have {count:plural} items.", {
    plural: {
      count: {
        type: "cardinal",
        zero: "no {?}",
        one: "{?} item",
        other: "{?} items"
      }
    }
  }),
  status: dt("Status: {state:enum}", {
    enum: {
      state: {
        active: "Active",
        inactive: "Inactive",
        pending: "Pending"
      }
    }
  }),
  nested: {
    profile: {
      title: "User Profile"
    }
  }
};

const esTranslations = {
  greeting: "Hola, {name}!",
  items: dt("Tienes {count:plural} artículos.", {
    plural: {
      count: {
        type: "cardinal",
        zero: "ningún {?}",
        one: "{?} artículo",
        other: "{?} artículos"
      }
    }
  }),
  status: dt("Estado: {state:enum}", {
    enum: {
      state: {
        active: "Activo",
        inactive: "Inactivo",
        pending: "Pendiente"
      }
    }
  }),
  nested: {
    profile: {
      title: "Perfil de Usuario"
    }
  }
};

// Initialize i18n
const { t } = await initI18n({
  locale: "en-US",
  fallbackLocale: "en",
  translations: {
    en: enTranslations,
    es: esTranslations
  }
});

// Type-safe translation with parameters
console.log(t("greeting", { name: "Alice" }));
// Output: "Hello, Alice!"

// Pluralization with automatic number formatting
console.log(t("items", { count: 0 }));  // "You have no items."
console.log(t("items", { count: 1 }));  // "You have 1 item."
console.log(t("items", { count: 5 }));  // "You have 5 items."

// Enum substitution
console.log(t("status", { state: "active" }));
// Output: "Status: Active"

// Nested key access with dot notation
console.log(t("nested.profile.title"));
// Output: "User Profile"

```

--------------------------------

### Define Settings Slice Typescript

Source: https://github.com/elian-argentics/complexity/blob/nxt/perplexity/extension/docs/articles/refactor/refactoring-zustand-stores.md

Defines the TypeScript interface for the Settings slice, including the current theme ('dark' or 'light') and a function to toggle the theme. This provides a clear contract for theme management.

```typescript
export interface SettingsSlice {
  theme: "dark" | "light";
  toggleTheme: () => void;
}
```

--------------------------------

### Register Feature Dependencies in TypeScript

Source: https://github.com/elian-argentics/complexity/blob/nxt/packages/async-dep-manager/README.md

Demonstrates how to extend the AsyncDependencyRegistry with feature-specific dependencies in separate TypeScript files. It shows defining types and registering loader functions for configuration and services, including cross-feature dependencies.

```typescript
// feature-a-dependencies.ts
import { createAsyncDependencyRegistry } from "./registry";

// Extend the registry with this feature's dependencies
declare module "./registry" {
  interface YourAppRegistry {
    featureAConfig: { apiKey: string };
    featureAService: { getData: () => Promise<unknown> };
  }
}

// Get the dependency manager instance
const asyncDependencyRegistry = createAsyncDependencyRegistry();

// Register this feature's dependencies
asyncDependencyRegistry.register({
  id: "featureAConfig",
  dependencies: [],
  loader: () => ({ apiKey: "feature-a-api-key" }),
});

asyncDependencyRegistry.register({
  id: "featureAService",
  dependencies: ["featureAConfig"],
  loader: (deps) => ({
    getData: async () => {
      console.log(`Using API key: ${deps.featureAConfig.apiKey}`);
      return { result: "Feature A data" };
    },
  }),
});

// feature-b-dependencies.ts
import { createAsyncDependencyRegistry } from "./registry";

// Extend the registry with this feature's dependencies
declare module "./registry" {
  interface YourAppRegistry {
    featureBUtils: { formatData: (data: unknown) => string };
    featureBService: { processData: (input: string) => Promise<string> };
  }
}

// Get the dependency manager instance
const asyncDependencyRegistry = createAsyncDependencyRegistry();

// Register this feature's dependencies
asyncDependencyRegistry.register({
  id: "featureBUtils",
  dependencies: [],
  loader: () => ({
    formatData: (data) => JSON.stringify(data, null, 2),
  }),
});

asyncDependencyRegistry.register({
  id: "featureBService",
  dependencies: ["featureBUtils", "featureAService"], // Dependencies can cross features
  loader: async (deps) => ({
    processData: async (input) => {
      const data = await deps.featureAService.getData();
      return deps.featureBUtils.formatData({ input, data });
    },
  }),
});
