clrlg

Improve the standard console.log output by adding Color Logging, timers and timestamps. High performance and Easy to Setup and Use.

Getting Started

Require the clrlg into your node app, and then use it instead of the standard console.log. Give more meaning to your console output, by adding colors, and timers.

Installing

To use the clrlg module you first need to install it into your app project. We recommend installing it globally (-g)

$ npm install -g clrlg 

To install just for your current project, from the project folder:

npm install --save clrlg 

Using

To use clrlg inside your project app.

In your code include the installed module.

const c = require("clrlg");

//const c = new clrlg(); not longer constructor 'new' required

Now output to the terminal from anywhere in your code using he lg method.

c.lg("default color output");

Output using many different colors with the second parameter.

c.lg("text to output","red|yellow|blue|green|magenta|grey|white(default)|cyan");

For example

c.lg("red","red"); //add second parameter of color

c.lg("yellow","yellow");

c.lg("blue","blue");

c.lg("green","green");

c.lg("magenta","magenta");

c.lg("grey","grey");

c.lg("white","white");

c.lg("cyan","cyan");

c.lg("non color","fishcolor"); //enter a non existent color.

Output timestamp prefix.

c.timestamp = true; //turn on prefix timestamp

c.lg("output some text");

c.lg("red","red"); //add second parameter of color

c.lg("blue","blue");

c.timestamp = false; //turn off prefix timestamp

c.lg("blue without timestamp prefix","blue");

Setup a timer.

c.start("a"); //start timer

setTimeout(() => {
  c.end("a");
},5500); //stop timers - after 5.5 seconds

Pass a callback function, so console output describes the callback function.

c.lg("doing DB lookup of id",() => {
  //retrieve data from db
  //return data
})

Running the tests

Mocha is used to unit test clrlg. Currently this is minimalistic to prove the build is successful. From the command line:

npm test

Built With

• Mocha - JavaScript test framework.
• colors - Color outputs.
