@yetnt/progressbar

progressbar.js

A progress bar creator in javascript!

Installation

npm i @yetnt/progressbar

Usage (examples below this)

const { progressBar, ProgressBar } = require('@yetnt/progressbar')

progressBar(percentage, barWidth, emptyChars, fullChars, returnAr?, firstEdgeOverride?, lastEdgeOverride?)

percentage = 45 // How much of the bar is full. If 100% the whole thing is full. If 0 everything is empty.
barWidth = 10 // Width of the bar. If 10 it's 10 characters long
emptyChars = "□" // Empty character to display for parts of the bar that aren't filled.
fullChars = "■" // Full character to display for parts of the bar that  are filled.
returnAr = false // (optional) Return an array or not
firstEdgeOverride = ["◁", "◀"] // (optional) Overrides the first edge with the elements
lastEdgeOverride = ["▷", "▶"] // (optional) Overrides the last edge with elements

// This is exactly the same for class, but returnAr is not a parameter

let bar = new ProgressBar(percentage, barWidth, emptyChars, fullChars, firstEdgeOverride?, lastEdgeOverride?)

or if you don't want to deconstruct the function (for some reason)

const pb = require("@yetnt/progressbar");
pb.progressBar();
// or
new pb.ProgressBar();

A Simple bar

Function

progressBar(45, 10, "□", "■");

Class

let bar = new ProgressBar(45, 10, "□", "■");
bar.bar;

Output

"■■■■□□□□□□";

Return Array

Function

progressBar(45, 10, "□", "■", true);

Class

let bar = new ProgressBar(45, 10, "□", "■", true);
bar.barArray;

Output

["■", "■", "■", "■", "□", "□", "□", "□", "□", "□"];

Edge overrides

If you'd like you can also change the first bar element and the last bar element so you can edge it with emojis or something else.

Edge Syntax

["emptyChar", "filledChar"];

Edge Use

Function

progressBar(56, 30, "▢", "▧", false, ["◁", "◀"], ["▷", "▶"]);

Class

let bar = new ProgressBar(56, 30, "▢", "▧", ["◁", "◀"], ["▷", "▶"]);
bar.bar;

Output

"◀▧▧▧▧▧▧▧▧▧▧▧▧▧▧▧▢▢▢▢▢▢▢▢▢▢▢▢▢▷";

Differences

The main difference between the function and the class (apart from one being a class and the other a function), is that when you update the barWidth/percentage properties in the class, the bar also updates.

Example

let bar = new ProgressBar(56, 30, "▢", "▧", ["◁", "◀"], ["▷", "▶"]);
bar.bar // ◀▧▧▧▧▧▧▧▧▧▧▧▧▧▧▧▢▢▢▢▢▢▢▢▢▢▢▢▢▷
bar.barWidth = 20
bar.bar // ◀▧▧▧▧▧▧▧▧▧▧▢▢▢▢▢▢▢▢▷
bar.percentage = 80
bar.bar // ◀▧▧▧▧▧▧▧▧▧▧▧▧▧▧▧▢▢▢▷

Warning : Bar may not work properly if you edit any other properties that aren't meant to be edited.
