# Voice Message Integration Module
## Overview
This module provides functionality for recording and sending audio messages within a messaging system. It includes endpoints for uploading voice messages, a React UI component for recording, and data schema validation.
## Components
### 1. FastAPI Endpoint (Voice Message Upload)
```python
from fastapi import APIRouter, Depends, HTTPException
from fastapi.responses import JSONResponse
import os
from typing import Optional
from pydantic import BaseModel
router = APIRouter()
class VoiceMessage(BaseModel):
user_id: str
message_text: str
audio_file_path: Optional[str] = None
@router.post("/voice-messages")
async def upload_voice_message(
file: bytes = File(...),
user_id: str = Form(...),
message_text: str = Form(...)
):
try:
# Create directory if not exists
os.makedirs("uploads", exist_ok=True)
audio_path = f"uploads/{user_id}/message_{datetime.now().isoformat()}.wav"
with open(audio_path, "wb") as f:
f.write(file)
return JSONResponse(
content={"status": "success", "message": "Voice message uploaded successfully"},
status_code=201
)
except Exception as e:
raise HTTPException(status_code=500, detail=str(e))
2. React UI Component (Voice Recording)
import React, { useState, useEffect } from 'react';
import { useAudioContext } from 'use-audio';
export default function VoiceRecorder() {
const [isRecording, setIsRecording] = useState(false);
const [audioBlob, setAudioBlob] = useState(null);
const [{ audioContext }, initAudioContext] = useAudioContext();
useEffect(() => {
return () => {
if (audioContext) {
audioContext.close();
}
};
}, [audioContext]);
const startRecording = async () => {
try {
await initAudioContext();
setIsRecording(true);
setAudioBlob(null);
} catch (error) {
console.error('Error initializing audio context:', error);
}
};
const stopRecording = async () => {
if (!audioContext) return;
const track = audioContext.activeTrack;
if (track) {
const buffer = await track.getSamples();
const blob = new Blob([buffer], { type: 'audio/wav' });
setAudioBlob(blob);
setIsRecording(false);
}
};
const handleSubmit = async () => {
if (!audioBlob) return;
// Implement your API call here
try {
const response = await fetch('/api/voice-messages', {
method: 'POST',
body: new FormData({
file: audioBlob,
user_id: 'user_123',
message_text: 'This is a voice message.'
})
});
if (!response.ok) throw new Error('Failed to upload');
console.log('Voice message uploaded successfully');
} catch (error) {
console.error('Error:', error);
}
};
return (
<div className="voice-recorder">
{!isRecording ? (
<button onClick={startRecording}>Start Recording</button>
) : (
<button onClick={stopRecording}>Stop Recording</button>
)}
{audioBlob && (
<div>
<p>Recorded audio ready to send.</p>
<button onClick={handleSubmit}>Send Message</button>
</div>
)}
</div>
);
}
3. Pydantic Data Schema (VoiceMessage)
from pydantic import BaseModel, Field
import uuid
from datetime import datetime
class VoiceMessage(BaseModel):
id: str = Field(
default_factory=lambda: str(uuid.uuid4()),
description="Unique identifier for the voice message",
example="550e8400-2693-4d4a-adb7-5c1d3c62f566"
)
user_id: str = Field(
...,
min_length=1,
description="ID of the user who sent the message",
example="user_123"
)
message_text: str = Field(
default="Voice message",
description="Text representation of the voice message",
example="Hello, this is a test message."
)
audio_file_path: Optional[str] = Field(
None,
description="Path to the stored audio file",
example="/uploads/user_123/2024-01-20T15:30:45.123.wav"
)
created_at: datetime = Field(
default_factory=lambda: datetime.now(),
description="Timestamp when message was created",
example="2024-01-20T15:30:45.123456Z"
)
class Config:
arbitrary_types_allowed = True
json_schema_extra = {
"example": {
"id": "550e8400-2693-4d4a-adb7-5c1d3c62f566",
"user_id": "user_123",
"message_text": "Hello, this is a test message.",
"audio_file_path": "/uploads/user_123/2024-01-20T15:30:45.123.wav",
"created_at": "2024-01-20T15:30:45.123456Z"
}
}
Usage
FastAPI Endpoint
- Send a POST request to
/voice-messageswith:file: Audio file in bytes (required)user_id: User ID as string (required)message_text: Message text as string (optional)
React Component
- Use the component to record audio:
- Click “Start Recording”
- Speak into your microphone
- Click “Stop Recording”
- Click “Send Message” to upload
Data Schema Validation
- Validate voice message data using Pydantic schema before sending to the backend.
Example
# Using FastAPI endpoint:
import requests
response = requests.post(
'http://localhost:8000/voice-messages',
files={'file': open('message.wav', 'rb')},
data={
'user_id': 'user_123',
'message_text': 'Hello, this is a test message.'
}
)
print(response.status_code) # Should be 201 Created
Notes
- Ensure microphone permissions are enabled in the browser for React component.
- Audio files will be saved to
/uploads/{user_id}directory.
