---

A tiny JavaScript debugging utility modelled after Node.js core's debugging technique. Works in Node.js and web browsers.debug exposes a function; simply pass this function the name of your module, and it will return a decorated version of console.error for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.

node-bunyan - a simple and fast JSON logging module for node.js services

---

Manifesto: Server logs should be structured. JSON's a good format. Let's do that. A log record is one line of JSON.stringify'd output. Let's also specify some common names for the requisite and common fields for a log record (see below).Stable. I do my best to follow semver: i.e. you should only need to worry about code breaking for a major version bump. Bunyan currently supports node 0.10 and greater. Follow @trentmick for updates to Bunyan.

chalk - 🖍 Terminal string styling done right

---

Chalk comes with an easy to use composable API where you just chain and nest the styles you want.Chain styles and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that chalk.red.yellow.green is equivalent to chalk.green.

node-draftlog - 📜 Create updatable log lines into the terminal, and give life to your logs!

---

It allows you to re-write a line of your log after being written. Just like post 'updating'. This is the building block for any dynamic element such as progress bars, loading status, animations, checkboxes and so on.It does that by keeping track of the current lines of code written through the stream, and moving the cursor up to the line of the LogDraft you created previously, and updating its content.

Rainbow - Delightful console output for Swift developers.

---

Rainbow adds text color, background color and style for console and command line output in Swift. It is born for cross platform software logging in terminals, working in both Apple's platforms and Linux. Thanks to the open source of Swift, developers now could write cross platform programs with the same language. And I believe the command line software would be the next great platform for Swift. Colorful and well organized output always helps us to understand what happens. It is really a necessary utility to create wonderful software.

Timber - A logger with a small, extensible API which provides utility on top of Android's normal Log class

---

This is a logger with a small, extensible API which provides utility on top of Android's normal Log class. Behavior is added through Tree instances. You can install an instance by calling Timber.plant. Installation of Trees should be done as early as possible. The onCreate of your application is the most logical choice. The DebugTree implementation will automatically figure out from which class it's being called and use that class name as its tag. Since the tags vary, it works really well when coupled with a log reader like Pidcat.

gollum - An n:m message multiplexer written in Go

---

Gollum is an n:m multiplexer that gathers messages from different sources and broadcasts them to a set of destinations.Gollum originally started as a tool to MUL-tiplex LOG-files (read it backwards to get the name). It quickly evolved to a one-way router for all kinds of messages, not limited to just logs. Gollum is written in Go to make it scalable and easy to extend without the need to use a scripting language.
