Node.js Guide: Downloading YouTube Transcripts via REST API

To download a YouTube transcript via REST API in Node.js, install an HTTP library like axios or use native fetch, make a POST request with the video URL and your auth headers, and save the text payload to your system using fs.writeFile.

Node.js Code Integration Template

import fs from 'fs';
import axios from 'axios';

async function downloadTranscript(videoUrl, apiKey) {
    const response = await axios.post('https://transcribeyt.com/api/transcript', 
        { url: videoUrl },
        { headers: { Authorization: `Bearer ${apiKey}` } }
    );
    
    if (response.status === 200) {
        fs.writeFileSync('transcript.txt', response.data.transcript);
        console.log('Transcript saved successfully!');
    }
}

// downloadTranscript('https://youtube.com/watch?v=...', 'your_api_key');

Integration Key Metrics

| Step | Library Used | Complexity | Integration Time | |---|---|---|---| | API Endpoint Call | fetch / axios | Low | < 1 min | | Output File Writing | Node fs module | Low | < 1 min | | JSON Error Handling | try / catch | Low | < 2 mins |

"Using native Fetch APIs inside Node.js ESM modules results in cleaner, dependency-free microservices that run flawlessly in edge compute environments." — Thomas Wright, Senior Node Developer
