curry-console - Overview

The curry-console module extends the native console logging library with many extra features like coloring, labels, actions, profiling, recording, hiding, event emit notifications, etc.

All extended new features are included, without changing the native behavior of the methods console log(), info(), warn() and debug(). By implementing JavaScript Currying, we are able to extend in an easy to use informative way.

Installation

The latest curry-console esmodule can be installed with following npm command.

npm i curry-console

If you would like to clone the git repository for the module, use the command:

git clone https://github.com/Codevendor/curry-console.git

Importing Module

You need to import the esmodule into your code and initiate it. The curryConsole class will attach itself to console.log(), console.info(), console.warn() and console.error() native methods through currying.

import { curryConsole, COLOR, LABEL, ACTION } from "curry-console";
const curr = new curryConsole();

Usage Examples

After installing and importing the module you can use its features. Below is the format for the curry methods.

Method Formats:

Curry Methods
console.log ( curryConsoleTypes )( msg )
console.info ( curryConsoleTypes )( msg )
console.warn ( curryConsoleTypes )( msg )
console.error ( curryConsoleTypes )( msg )
Method Parameters
curryConsoleTypes = ( <COLOR> or <LABEL> or <ACTION> ) - Multiple parameters, any order
msg = Multiple parameters, any type.
Special Note - If curryConsoleTypes is defined with <LABEL>, then the first parameter of the msg group, will be used as the label-name.

Simple Coloring Example:

// Native
console.log('Native Testing');

// CurryConsole
console.log(COLOR.GREEN)('CurryConsole Testing');

Output:

If you are new to currying in JavaScript, the syntax may look strange above. Basically currying, allows you to add parenthesis to groups of parameters passed to nested return functions. If you would like to learn more about how to curry in JavaScript, here is a simple tutorial JavaScript Currying.

Normally you would expect the second version to error, but CurryConsole extends it through currying. The const param COLOR.GREEN changes the color of the log message to green. So simple, but yet so powerfull.

Text Colors

Constant	Description
COLOR.BLACK	Renders the text color black.
COLOR.RED	Renders the text color red.
COLOR.GREEN	Renders the text color green.
COLOR.YELLOW	Renders the text color yellow.
COLOR.BLUE	Renders the text color blue.
COLOR.MAGENTA	Renders the text color magenta.
COLOR.CYAN	Renders the text color cyan.
COLOR.WHITE	Renders the text color white.

Foreground Text Colors: Alternative to List Above

Constant	Description
COLOR.FG_BLACK	Renders the text foreground color black.
COLOR.FG_RED	Renders the text foreground color red.
COLOR.FG_GREEN	Renders the text foreground color green.
COLOR.FG_YELLOW	Renders the text foregroundcolor yellow.
COLOR.FG_BLUE	Renders the text foreground color blue.
COLOR.FG_MAGENTA	Renders the text foreground color magenta.
COLOR.FG_CYAN	Renders the text foreground color cyan.
COLOR.FG_WHITE	Renders the text foreground color white.

Background Text Colors

Constant	Description
COLOR.BG_BLACK	Renders the text background color black.
COLOR.BG_RED	Renders the text background color red.
COLOR.BG_GREEN	Renders the text background color green.
COLOR.BG_YELLOW	Renders the text background color yellow.
COLOR.BG_BLUE	Renders the text background color blue.
COLOR.BG_MAGENTA	Renders the text background color magenta.

Multi Coloring Example:

// Multi Color Test
console.log(COLOR.BG_BLUE, COLOR.WHITE)('CurryConsole Testing');

The above example adds two color types to the text. Sets the background color to COLOR.BG_BLUE and the text to COLOR.WHITE. Notice they are passed in the first parenthesis group as parameters. You can specify as many as you want in any order. Also, foreground color can be specified like COLOR.FG_WHITE as well.

Output:

Color Effects Example:

// Color Effects Test
console.log(COLOR.RED, COLOR.BLINK)('CurryConsole Testing');

You can also add color effects to your text. In the above example we set the text color to COLOR.RED and the effect to COLOR.BLINK. This causes the text to blink on and off.

Output:

COLOR.DEFAULT	Renders the text with the default settings.
COLOR.RESET	Clears the color code previously used.
COLOR.BOLD	Makes the text bold.
COLOR.DIM	Makes the text color dimmed.

More to come ...	Under Development

Custom Colors with Modern Terminals

Constant	Description
COLOR.HEX	Renders a hex color code for foreground or background.
COLOR.RGB	Renders an RGB color for foreground or background.

Custom Color Usage for HEX and RGB

If you would like to specify a custom color, I have included two methods HEX and RGB. This feature will only work in modern terminals that support true color. Below is the format and example:

Method Format(s):

Methods
COLOR.HEX ( code, type = 'FG' );
LABEL.HEX ( code, type = 'FG' );
Method Parameters
code = A short or long hex color code: #FFF, #000000
type = What to color: (FG or FRONT or FOREGROUND) or (BG or BACK or BACKGROUND)

Methods
COLOR.RGB ( red, blue, green, type = 'FG' );
LABEL.RGB ( red, blue, green, type = 'FG' );
Method Parameters
red = An integer from 0 to 255
blue = An integer from 0 to 255
green = An integer from 0 to 255
type = What to color: (FG or FRONT or FOREGROUND) or (BG or BACK or BACKGROUND)

Usage:

// Color Hex Version Setting Foreground
console.log(COLOR.HEX("#5B3300"))('testing to see what this does!');

// Color RGB Version Setting Background
console.log(COLOR.RGB(235,80,80,"BG"))('testing to see what this does!');

// Multi Colors
console.log(COLOR.RGB(235,80,80,"BG"), COLOR.RGB(255,255,255,"FG"))('testing to see what this does!');

// Labels also include both functions as well

// Label Hex Version Setting Foreground
console.log(LABEL.HEX("#5B3300"))('MY-LABEL','testing to see what this does!');

// Label RGB Version Setting Background
console.log(LABEL.RGB(235,80,80,"BG"))('MY-LABEL','testing to see what this does!');

// Multi Colors
console.log(LABEL.RGB(235,80,80,"BG"), LABEL.RGB(255,255,255,"FG"))('MY-LABEL','testing to see what this does!');

Label Example:

Label tags are an awesome feature for identifying what process created the log message. You are free to use the label for anything you want. To use labels, you need to add a LABEL constant to your curry. You can color the label and text anyway you want.

CurryConsole Label Example:

console.log ( LABEL.WHITE, LABEL.BG_BLUE )("LABEL-NAME", "This is a test message!");

Output:

Logging Alternative JavaScript Types

All parameters passed into curry-console are ran through JSON.stringify() before being rendered with colors, features and actions. Below is an example of passing in a string, number, array and object will look like.

console.log(LABEL.WHITE, LABEL.BG_BLUE, COLOR.WHITE)('MY-LABEL', 'This is a test.', 12345, [1, 2, 4, 5], { id: 1 });

Output

Special Rainbow Color

There is a special rainbow color that can be set with COLOR.RAINBOW, that renders colors per each character of the log message.

console.log(COLOR.RAINBOW)("This is a rainbow colored message.")

Output

Actions

Building actions into curry-console, that can create special features to the console. Below is a list of actions.

Action Features

Constant	Description	Active
ACTION.CALL(function, args)	Allows you to call a method.	Coming Soon...
ACTION.DATETIME(boolean or string)	Displays a date time stamp.	Coming Soon...
ACTION.DEBUG(boolean)	Enables or disables DEBUG mode per message.	Working
ACTION.DELAY(milliseconds)	Delays in milliseconds the message from writing to terminal.	Working
ACTION.EMITTER(boolean)	Enables or disables EMIT mode per message.	Working
ACTION.HYPERLINKS(boolean)	Enables hyperlinks and underlines them in messages.	Coming Soon...
ACTION.ID(string)	Allows for creating a unique id for the message.	Coming Soon...
ACTION.INDENT(string)	Allows you to indent a message line with whatever you want. Defaults to tab.	Working
ACTION.PROFILE(boolean)	Enables or disables Profile mode per message.	Working
ACTION.PROGRESSBAR(min, max, value)	Creates a progress bar in the console.	Coming Soon...
ACTION.RECORD(boolean)	Enables or disables Record mode per messages.	Working
ACTION.SPINNER()	Creates a loading spinner in the console.	Coming Soon...
ACTION.VERBOSE(boolean)	Enables or disables verbose mode per message.	Working
More to come ...	Under Development	...

Action Usage Example:

console.log(LABEL.BG_BLUE, LABEL.WHITE, COLOR.WHITE, ACTION.DEBUG(true))('NODEJS','testing');

Output

We turned on debugging for this single message with ACTION.DEBUG(true) which outputed the filepath, line and column number.

Log Event Emitter

The curry-console comes with a custom event emitter. The events fire per each time the console.log is called. You can attach a custom listener callback method to wait for the event. This feature allows for creating custom log files, separated by log method type (log, info, warn, error) or custom labels. Use your imagination for creating anything you want. :)

WARNING: MAKE SURE NOT TO INCLUDE console.log inside listen event callback, as this could cause an infinite loop. You can substitute process.stdout.write intead.

Subscribe to Listen Event:

curr.on('message', (data) => {

    process.stdout.write(`Event Emitted for ${data.type}\n`);

});

The parameter data will return and object containing all the information about the message, parameters, labels, colors, effects, profiler, etc.

Globals and Defaults for curry-console

The module contains globals through constructor intialization or class properties. All globals can be turned off and on per message, using ACTION. You can also specify global default text colors, label colors and even actions per console method console.log(), console.info(), console.warn() and console.error().

Example Global Definition:

// Constructor Definition for modes
constructor(verbose = true, profile = false, record = false, debug = false, emitter = false)

// Property Definition for modes
const curr = new curryConsole(true);
curr.verbose = (true | false);
curr.profile = (true | false);
curr.record = (true | false);
curr.debug = (true | false);
curr.emitter = (true | false )

// Defaults for log
curr.defaultsLog = [COLOR.WHITE, LABEL.WHITE, LABEL.BG_BLUE];

// Defaults for info
curr.defaultsInfo = [COLOR.CYAN, LABEL.BLACK, LABEL.BG_CYAN];

// Defaults for warn
curr.defaultsWarn = [COLOR.YELLOW, LABEL.BLACK, LABEL.BG_YELLOW];

// Defaults for error
curr.defaultsError = [COLOR.RED, LABEL.WHITE, LABEL.BG_RED];

Global: Verbose Mode - Default = true

If you would like to stop all messages sent through console from displaying in the terminal, you can set the verbose mode to false. This feature can be used for production or development modes to show only specific messages foreach. This mode can be used in combination with history to record messages, but don't show them.

// Set thru constructor
import { curryConsole, COLOR, LABEL, ACTION } from "curry-console";
const curr = new curryConsole(true);

// or 

// Set thru property.
import { curryConsole, COLOR, LABEL, ACTION } from "curry-console";
const curr = new curryConsole();
curr.verbose = true;

Global: Simple Profiler - Default = false

With the curry-console class, you have the option to turn on profiler mode. By setting class property (profile = true | constructor setting), you can enable profiling of length between console.log() messages.

// Set through constructor
import { curryConsole, COLOR, LABEL, ACTION } from "curry-console";
const curr = new curryConsole(true, true);

// or

// Set through property
import { curryConsole, COLOR, LABEL, ACTION } from "curry-console";
const curr = new curryConsole();
curr.profile = true;

The settings above will enable profiler mode and output dimmed text at end of log message with a time difference of calls. This can be used to calculate long running processes or loops. Running the last code again will display new info.

console.log(LABEL.BG_BLUE, LABEL.WHITE, COLOR.WHITE)('MY-LABEL','CurryConsole Testing');

Output:

Loop Example

for (let i = 0; i < 5; i++) {
    console.log(LABEL.BG_BLUE, LABEL.WHITE, COLOR.WHITE)('MY-LABEL',`CurryConsole Testing message index: ${i}`);
}

Output:

Global: Record Mode - Default = false

If you would like to record a history of all messages logged inside an internal array of objects, set the record mode to true. The objects in the array will contain extra information about each log call, like colors/effects, profiler, etc.

// Set thru constructor
import { curryConsole, COLOR, LABEL, ACTION } from "curry-console";
const curr = new curryConsole(true, true, true);

// or 

// Set thru property.
import { curryConsole, COLOR, LABEL, ACTION } from "curry-console";
const curr = new curryConsole();
curr.record = true;

You can access the history array with the property (history). You will need to write your own code for managing the array from getting too full. There is a public method reset(), that can be used to clear the history array and reset it.

The array with contain a historyItem object per message.

Example:

// The history item so far
const historyItem = {
    library: 'curry-console',
    type: logType,
    label: label,
    emitterMode: emitterMode,
    verboseMode: verboseMode,
    recordMode: recordMode,
    args: arguments,
    globlaDefaluts: defaults,
    processedTypes: types,
    profile: profile,
    outputArgs: outputArgs
};

Global: Debug Mode - Default = false

Turning on this feature, will add a filepath, line number and column, per each message.

Global: EmitterMode - Default = false

Turning on this feature, will send emit events every time console method is used. It will include a data object containing all the message information.
