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 🙏

Simple Logger

Simple Logger is a lightweight and easy-to-use logging library for Node.js applications. It provides a simple and intuitive way to log messages with different severity levels, format log messages, and rotate log files.

Installation

To install Simple Logger, use npm:

npm install simplest-fancy-logger

Usage

First, require the SimpleLogger class in your Node.js application:

import SimpleLogger from "simplest-fancy-logger"

Then, create an instance of the SimpleLogger class with the desired configuration options:

const logger = new SimpleLogger({
  logLevel: "debug",
  logFile: "app.log",
  logFormat: "[{level}] [{timestamp}] - {message} - {emoji}",
  dateFormat: "yyyy-mm-dd HH:MM:ss",
  maxFileSize: 1024 * 1024 * 5, // 5MB
  maxFiles: 3,
})

Now you can use the logger instance to log messages with different severity levels:

logger.info("This is an informational message")
logger.warn("This is a warning message")
logger.error("This is an error message")
logger.debug("This is a debug message")

The log messages will be outputted to the console and written to the specified log file.

Output Examples

Here are some examples of how the log messages will be outputted using Simple Logger:

alt text

The log messages include the following components:

  • Log Level: The severity level of the message, displayed in uppercase and colored based on the level.
  • Timestamp: The timestamp of when the log message was generated, formatted according to the dateFormat configuration option.
  • Message: The actual log message.
  • Emoji: An emoji corresponding to the log level, providing a visual indication of the message severity.

The log messages will be outputted to the console and written to the specified log file (if configured) in the same format.

Configuration Options

The SimpleLogger class accepts the following configuration options:

  • logLevel (string, default: 'info'): The minimum severity level of messages to log. Can be one of 'error', 'warn', 'info', or 'debug'.
  • logFile (string, default: null): The path to the log file. If not specified, logs will only be outputted to the console.
  • logFormat (string, default: '[{level}] [{timestamp}] - {message} - {emoji}'): The format of the log messages. You can use placeholders {level}, {timestamp}, {message}, and {emoji} to customize the format.
  • dateFormat (string, default: 'yyyy-mm-dd HH:MM:ss'): The format of the timestamp in log messages.
  • maxFileSize (number, default: 1024 * 1024 * 10): The maximum size (in bytes) of the log file before it gets rotated.
  • maxFiles (number, default: 5): The maximum number of rotated log files to keep.

Log Levels

Simple Logger supports the following log levels, in decreasing order of severity:

  • error: Error messages.
  • warn: Warning messages.
  • info: Informational messages.
  • debug: Debug messages.

Log File Rotation

Simple Logger automatically rotates the log file when it reaches the specified maximum size. The rotated log files are named with a numbered suffix (e.g., app.log.1, app.log.2, etc.). The number of rotated log files is limited by the maxFiles configuration option.
