sanp-logger v1.0.1

sanp-logger

Sanp-Logger: A flexible middleware for Node.js that logs HTTP requests and responses in a readable format. Supports console/file logging with customizable details like method, status, duration, IP, and user-agent.

Features

• Customizable Logging: Log incoming requests, response status codes, duration, HTTP methods, paths, IP addresses, and user-agents.
• Color-Coded Console Output: Colorful output for better readability in the terminal.
• Log to File: Optionally log the details to a file (logs.txt by default).
• Easy Integration: Simple middleware that can be integrated into Express.js or similar Node.js frameworks.

Installation

npm install sanp-logger

Usage

Basic Usage

In your Node.js/Express application, you can use sanp-logger as middleware:

const express = require("express");
const loggger = require("sanp-logger"); // Import the sanp-logger package

const app = express();

app.use(loggger());

app.get("/", (req, res) => {
  res.send("Hello World!");
});

app.listen(3000, () => {
  console.log("Server is running on http://localhost:3000");
});

Output

When a request is made to the server, you'll see a log like:

[INFO] GET / 200 0.003s

• Method: GET
• Route: /
• Status Code: 200
• Request Duration: 0.003 seconds (color-coded)

Example with Customization

You can also customize the logger behavior by passing options:

const express = require("express");
const performanceLogger = require("perf-logx");

const app = express();

// Use the logger middleware with customized options
app.use(
  performanceLogger({
    logIncoming: true, // Log incoming requests
    logStatusCode: true, // Log response status codes
    logDuration: true, // Log the request duration
    logMethod: true, // Log the HTTP method
    logPath: true, // Log the request path
    logIP: true, // Log the IP address of the requester
    logUserAgent: true, // Log the User-Agent of the requester
  })
);

// Example route
app.get("/example", (req, res) => {
  res.send("This is an example route.");
});

// Start the server
app.listen(3000, () => {
  console.log("Server is running on http://localhost:3000");
});

Configuration Options

You can customize what gets logged by passing an options object to loggger. The available options are:

Example with File Logging

app.use(
  loggger({
    logToFile: true, // Enable file logging
    //logFilePath: path.join(__dirname, "server_logs.txt")  Optional: Specify the log file path
  })
);

This will log the request details to the file logs.txt in the root of your project.

How It Works

The loggger middleware logs request and response information such as HTTP method, path, status code, duration, client IP, and user-agent. Logs can be color-coded in the console for better readability. If logToFile is enabled, it will append logs to a file (logs.txt by default) without color formatting for easy text-based reading.
