ongoing v1.0.2

Ongoing

A simple ascii progress bar renderer. It doesn't take care of printing the progress bar to the terminal, so that has to be done using other tools.

Installation

npm i ongoing

Example

import { ProgressBar } from 'ongoing';

const bar = new ProgressBar(':message :bar :percent');

console.log(bar.update(0.2, { message: 'Hello' }));
console.log(bar.tick(1, { message: 'World' }));

Features

• Custom tokens
• Update the bar to a specific value
• Tick the bar based on a delta

Default tokens

• :current: Displays the current value
• :total: Displays the total value
• :percent: Displays the current percentage
• :bar: Displays the bar (required)

Options

A second argument can be passed when instantiating the bar. The following options are supported:

• total: Indicates the maximum value of the progress bar
• width: Indicates the width in characters of the progress bar
• completedChar: Indicates the character to use to darw the completed section
• incompletedChar: Indicates the character to use to draw the incompleted section
• headChar: Indicates a character to draw as the head of the completed section

Default values

const bar = new ProgressBar(':bar', {
  total: 100,
  width: 30,
  completedChar: '=',
  incompletedChar: '-',
  headChar: '=',
});
