express-slowpoke-logger

A lightweight Express.js middleware that tracks API response times and logs slow requests using Winston. It helps identify performance bottlenecks in your application.

🚀 Features

• Logs all request response times.
• Highlights slow requests (default: 500ms threshold).
• Integrates seamlessly with Winston for customizable logging.
• Lightweight and easy to use.

📦 Installation

Install via npm:

npm install express-slowpoke-logger

🔧 Usage

Integrate the middleware into your Express.js app:

const express = require('express');
const slowpokeLogger = require('express-slowpoke-logger');

const app = express();
const PORT = process.env.PORT || 3000;

// Add the middleware
app.use(slowpokeLogger());

app.get('/', (req, res) => {
  setTimeout(() => {
    res.send('Hello World!');
  }, Math.random() * 1000); // Simulate variable response times
});

app.listen(PORT, () => {
  console.log(`Server running on http://localhost:${PORT}`);
});

⚙️ Configuration

You can customize the slow request threshold and logging level:

app.use(slowpokeLogger({ threshold: 300, level: 'warn' }));

Option	Type	Default	Description
threshold	Number	500	Time in milliseconds to log as slow.
level	String	'info'	Logging level for slow requests.
