Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

LogSwift

LogSwift is a simple and customizable logger for Node.js applications that logs messages to the console with timestamp, process ID, and location information (file, line number, and function name). It supports different log levels and colorized output.

Features

  • Basic Logging Levels: Log, Info, Debug, Warn, Error, Fatal.
  • Color-Coded Output: Enhance readability with color-coded log levels.
  • Readability: Logs messages with timestamp, process ID, file name, line number, and function name.

Installation

To install LogSwift, you need to have Node.js and npm installed. You can then install it via npm or yarn: Using NPM:

$ npm install log-swift

Using YARN:

$ yarn add log-swift

Usage

First, require the LogSwift module in your application:

const LogSwift = require('log-swift');
const logger = new LogSwift();

You can then use the logger to log messages at different levels:

logger.generic('This is a generic log message.');
logger.debug('This is a debug message.');
logger.info('This is an info message.');
logger.warn('This is a warning message.');
logger.error('This is an error message.');
logger.fatal('This is a fatal error message.');

Example

Here's a simple example demonstrating the usage of LogSwift:

const LogSwift = require('log-swift');
const logger = new LogSwift();

logger.info('Application has started.');

Output:

[05/26/2024, 12:47:00 GMT+5:30] [PID:28520] [INFO]
Message  : Application has started.
Location : example/logger-example.js: 4 (someFunctionName)

Configuration

LogSwift relies on two additional modules for log levels and log colors:

  • LogLevels: Define the log levels.
  • LogColors: Define the colors for each log level.
