print

A lightweight logger with automatic timestamps, smart data type detection, and timer management.

Features

• Named exports: Clean import { log, success, error } syntax
• Auto-formatting: Detects data types and formats appropriately
• Timer management: Built-in timing with automatic duration logging
• Environment awareness: Debug logs skip in production
• Timestamps: Optional timestamps on all logs
• TypeScript support: Full TypeScript definitions included
• ES Module support: Works in React/Next.js and Node.js

Installation

npm install @bitterbyter/print

Quick Start

ES Modules (React/Next.js)

import {
  log,
  success,
  error,
  info,
  warn,
  debug,
  startTimer,
  endTimer,
  configure,
} from "@bitterbyter/print";

// Configure
configure({
  environment: "development",
  timestamps: true,
});

// Basic logging
success("Operation completed!");
error("Something went wrong");
info("Here is some information");
warn("This might be an issue");
debug("Debug information"); // Only logs in development

// Auto-formatting
log("Hello World"); // Simple string
info({ name: "John" }); // Auto-formats as JSON
debug([1, 2, 3]); // Auto-formats as array
error(new Error("Oops")); // Auto-formats with stack trace

// Timer usage
startTimer("api-call");
// ... API call
endTimer("api-call"); // Auto-prints duration

CommonJS (Node.js)

const {
  log,
  success,
  error,
  info,
  warn,
  debug,
  startTimer,
  endTimer,
  configure,
} = require("@bitterbyter/print");

// Same usage as ES modules
configure({ environment: "development", timestamps: true });
success("Hello from Node.js!");

• debug(data) - Debug messages (development only)

Data Formatting

• table(data) - Display data as table
• count(label) - Count occurrences
• countReset(label) - Reset counter
• dir(data) - Display object properties
• dirxml(data) - Display XML/HTML structure

Timing

• startTimer(label) - Start timer
• endTimer(label) - End timer and log duration

Configuration

• configure(options) - Configure logger settings

Configuration Options

configure({
  environment: "development", // 'development' | 'production'
  timestamps: true, // Add timestamps to all logs
});

Auto-Formatting Examples

// Strings
log("Hello World");
// Output: [2024-01-15T10:30:45.123Z] Hello World

// Objects
info({ name: "John", age: 30 });
// Output: [2024-01-15T10:30:45.123Z] INFO: {
//   "name": "John",
//   "age": 30
// }

// Arrays
debug([1, 2, 3]);
// Output: [2024-01-15T10:30:45.123Z] DEBUG: Array(3): [1, 2, 3]

// Errors
error(new Error("Something went wrong"));
// Output: [2024-01-15T10:30:45.123Z] ERROR: Something went wrong
// Stack: Error: Something went wrong
//     at ...

// Timers
startTimer("operation");
// ... process
endTimer("operation");
// Output: [2024-01-15T10:30:45.123Z] INFO: Timer "operation" completed in 245ms
