raj-logger

A colorful Node.js logger with emojis, timestamps, pretty-printed JSON, and optional boxed output for enhanced terminal readability.

✨ Features

• 🎨 Colorful console logs with different styles per log level
• 😄 Emojis for quick visual recognition of log types
• ⏱ ISO-like timestamps on each log line
• 📜 Pretty print for objects and arrays with indentation
• 📦 Optional boxed output around JSON or text for emphasis
• 🌐 Global functions available everywhere (info(), err(), succ(), dbg(), etc.)
• ⚡ Zero dependencies — pure Node.js, no external packages

📦 Installation

npm install raj-logger

🚀 Usage

Require once to enable global log functions:

require("raj-logger");

Available functions:

| Function | Description | Emoji | Color | |------------|-----------------------------|-------|------------------| | info() | Informational messages | ℹ️ | Blue | | dbg() | Debugging details | 🐞 | Cyan (dimmed) | | warn() | Warnings | ⚠️ | Yellow | | fatal() | Fatal errors | 💀 | Bold Red | | succ() | Success messages | ✅ | Green | | err() | Error messages | ❌ | Red | | load() | Loading indicators | ⏳ | Magenta (dimmed) | | done() | Completed tasks | 🎯 | Bold Green | | upd() | Updates / Refreshes | 🔄 | Cyan | | event() | Special events | 🎉 | Magenta | | net() | Network-related logs | 🌐 | Blue | | sec() | Security alerts | 🔒 | Yellow/Magenta |

💡 Examples

Basic logging

info("Starting server..."); succ("Server started successfully"); warn("Memory usage high"); err("Failed to connect to database"); dbg({ user: "raj", status: "active" });

Logging with boxed output

dbg({ user: "raj", status: "active" }, { box: true }); err("Critical failure!", { box: true });

Logging arrays or complex objects

dbg(["apple", "banana", "cherry"], { box: true }); info({ server: "localhost", port: 3000, ssl: false });

Using in a real app

require("raj-logger");

succ("Application started"); warn("Deprecated API usage detected"); err("Unhandled exception"); load("Loading data from API..."); done("Data loaded successfully");

⚙️ How it Works

• Adds a timestamp and tag [raj-log] to each message
• Each log type has a unique emoji and color style
• If the message is an object or array, it is pretty-printed with indentation
• Optionally wraps the output in a neat ASCII box
• Registers global functions so you can call them anywhere without imports
