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 🙏

Readme

JSLogger

Javascript console abstraction - Keeps logging to a minimum in a production environment

##Usage

Currently jslogger is intended for web applications only.

Include in html doc

<script src="path/to/libraries/jslogger.js"></script>

In code

jslogger.log('I\'m going to become log output');
jslogger.log('%cI am output with style', 'color: #cccccc');
jslogger.debug('I am a debug message. I will not cause a deprecation warning');
//And so on

In console

jslogger.setLogLevel(3); //This will output everything up to debug level
jslogger.setLogLevel(0); //This will output only errors
jslogger.getLogLevel(); //Outputs log level, currently 0

Supported log levels

Each log level outputs everything from a lower log level and also includes listed functions.

  • 0: Error
  • 1: Warn
  • 2: Info and log
  • 3: Debug
  • 4: Trace

##Roadmap

  • Provide a configuration abstraction to allow for logging in node applications
  • Add expanded console support for modern API support (grouping and other modern functions)

##Update log

###v1.2.0

  • Added debug function which performs the following mapping at log level 3: debug -> console.log
  • Moved trace output to log level 4
  • Refactored code to eliminate unnecessarily repeated function behaviors
  • Pulled multi-parameter logging validation out of consoleCaller
  • Re-organized code for easier identification of critical moving parts
  • Added function mapping to allow for extended function naming and defintions without requiring complex logic
  • Adopted some principles of 'BOT' architecture model to simplify program logic and express expectations in a more declarative way

###v1.1.1

  • Fixed log level check. Regex was failing in a production environment
