Optimize Toolset

Iโ€™ve always been into building performant and accessible sites, but lately Iโ€™ve been taking it extremely seriously. So much so that Iโ€™ve been building a tool to help me optimize and monitor the sites that I build to make sure that Iโ€™m making an attempt to offer the best experience to those who visit them. If youโ€™re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, ๐Ÿ‘‹, Iโ€™m Ryan Hefnerย  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If youโ€™re interested in other things Iโ€™m working on, follow me on Twitter or check out the open source projects Iโ€™ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soonโ€“ish.

Open Software & Tools

This site wouldnโ€™t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you ๐Ÿ™

๐Ÿ”ฎ Use Cases

Real-time Voice Chat Applications

// Process voice messages as they arrive
conversational: {
  onChunk: (chunk) => {
    // Send to WebSocket, store in chat, trigger AI response
    sendVoiceMessage(chunk.audioUrl, chunk.transcript)
  }
}

Voice-to-Text Transcription Services

// Batch process audio files with real-time feedback
conversational: {
  onChunk: (chunk) => {
    updateTranscriptionProgress(chunk.startTime, chunk.transcript)
  }
}

AI Voice Assistants

// Build ChatGPT-style voice interfaces
conversational: {
  onChunk: async (chunk) => {
    const aiResponse = await openai.chat.completions.create({
      messages: [{ role: 'user', content: chunk.transcript }]
    })
    speakResponse(aiResponse.choices[0].message.content)
  }
}

๐Ÿ”ง Extension Points & Middleware

Susurro provides a powerful middleware system for extending chunk processing capabilities:

Chunk Middleware Pipeline

import { ChunkMiddlewarePipeline, translationMiddleware, sentimentMiddleware } from 'susurro'

function MyApp() {
  const { middlewarePipeline, startRecording } = useSusurro({
    conversational: {
      onChunk: (chunk) => {
        // Chunk has been processed through middleware pipeline
        console.log('Enhanced chunk:', chunk.metadata)
      }
    }
  })

  // Enable built-in middlewares
  useEffect(() => {
    middlewarePipeline.enable('translation')
    middlewarePipeline.enable('sentiment')
    middlewarePipeline.enable('intent')
  }, [])

  return <VoiceInterface />
}

Built-in Middlewares

1. Translation Middleware

middlewarePipeline.enable('translation')

// Chunks will include:
chunk.metadata = {
  originalLanguage: 'en',
  translatedText: 'Hola mundo',
  translationConfidence: 0.95
}

2. Sentiment Analysis Middleware

middlewarePipeline.enable('sentiment')

// Chunks will include:
chunk.metadata = {
  sentiment: 'positive',
  sentimentScore: 0.87,
  emotion: 'happy'
}

3. Intent Detection Middleware

middlewarePipeline.enable('intent')

// Chunks will include:
chunk.metadata = {
  intent: 'question',
  intentConfidence: 0.82,
  entities: ['weather', 'today']
}

4. Quality Enhancement Middleware (Always Enabled)

// Automatically applied to all chunks:
chunk.metadata = {
  audioQuality: 0.92,
  noiseLevel: 0.05,
  clarity: 0.96,
  enhancement: ['neural_denoising', 'voice_enhancement']
}

Creating Custom Middleware

import { ChunkMiddleware, SusurroChunk } from 'susurro'

const customMiddleware: ChunkMiddleware = {
  name: 'keyword-detection',
  enabled: true,
  priority: 5,
  async process(chunk: SusurroChunk): Promise<SusurroChunk> {
    const keywords = detectKeywords(chunk.transcript)
    
    return {
      ...chunk,
      metadata: {
        ...chunk.metadata,
        keywords,
        hasActionKeywords: keywords.some(k => k.type === 'action'),
        urgencyLevel: calculateUrgency(keywords)
      }
    }
  }
}

// Register your custom middleware
middlewarePipeline.register(customMiddleware)

function detectKeywords(text: string) {
  // Your custom keyword detection logic
  return [
    { word: 'urgent', type: 'urgency', confidence: 0.9 },
    { word: 'schedule', type: 'action', confidence: 0.8 }
  ]
}

Advanced Hooks & Callbacks

1. Chunk Processing Hooks

const { conversationalChunks } = useSusurro({
  conversational: {
    onChunk: (chunk) => {
      // Real-time processing as chunks arrive
      handleNewMessage(chunk)
    },
    enableInstantTranscription: true,
    chunkTimeout: 3000,
    enableChunkEnrichment: true, // Enables middleware processing
  }
})

2. Recording State Hooks

const { 
  isRecording,
  isProcessing,
  averageVad,
  processingStatus 
} = useSusurro()

// Monitor recording state changes
useEffect(() => {
  if (isRecording) {
    console.log('Recording started')
  }
}, [isRecording])

// Track processing progress
useEffect(() => {
  console.log('VAD Score:', averageVad)
  console.log('Processing Stage:', processingStatus.stage)
}, [averageVad, processingStatus])

3. Whisper Integration Hooks

const { 
  whisperReady,
  whisperProgress,
  whisperError,
  transcribeWithWhisper 
} = useSusurro({
  whisperConfig: {
    language: 'en',
    model: 'whisper-1',
    temperature: 0.2
  }
})

// Custom transcription with direct Whisper access
const handleCustomTranscription = async (audioBlob: Blob) => {
  const result = await transcribeWithWhisper(audioBlob)
  console.log('Custom transcription:', result)
}

Middleware Management API

const { middlewarePipeline } = useSusurro()

// Enable/disable middlewares dynamically
middlewarePipeline.enable('sentiment')
middlewarePipeline.disable('translation')

// Check middleware status
const status = middlewarePipeline.getStatus()
console.log('Active middlewares:', status)

// Register custom middleware
middlewarePipeline.register(myCustomMiddleware)

// Remove middleware
middlewarePipeline.unregister('sentiment')

WebSocket Integration Example

import { useSusurro } from 'susurro'
import { useWebSocket } from 'ws'

function CollaborativeVoiceChat() {
  const ws = useWebSocket('wss://my-server.com/voice-chat')
  
  const { startRecording, stopRecording } = useSusurro({
    conversational: {
      onChunk: (chunk) => {
        // Send chunk to other participants
        ws.send(JSON.stringify({
          type: 'voice-chunk',
          data: {
            audioUrl: chunk.audioUrl,
            transcript: chunk.transcript,
            metadata: chunk.metadata,
            userId: 'current-user-id'
          }
        }))
      },
      enableInstantTranscription: true
    }
  })

  // Handle incoming chunks from other users
  useEffect(() => {
    ws.onmessage = (event) => {
      const message = JSON.parse(event.data)
      if (message.type === 'voice-chunk') {
        displayRemoteChunk(message.data)
      }
    }
  }, [ws])

  return <VoiceInterface />
}
