Getting Started

Installing

As usual, you need to install from npm/yarn:

$ npm install cli-badges

Usage

This is a simple example, using badges to display test results:

const { badge } = require('cli-badges');

const failedBadge  = badge('failed', '2', { theme: 'red' });
const skippedBadge = badge.yellow('skipped', '2');
const successBadge = badge.green('success', '2');

console.log(failedBadge, successBadge, skippedBadge);

The above would output something similar to the terminal:

You could also create a donate badge with a link (if supported):

const donateBadge = badge.blue('❤️ donate', 'ko-fi', {
  link: 'https://ko-fi.com/logginjs',
});

console.log(donateBadge);

You can also only show the label:

const onlyLabel = badge('❤️ donate', '', { labelColor: 169 });

console.log(onlyLabel);
Example output is a mock, console output will vary slightly from terminal to terminal.

Badge Structure

A badge is conformed of a label and a message <label>:<message>. Each segment can be customized, by changing bg color, text color and style.

API

cli-badges exports a method called badge.

export function badge(
  label?: string,
  message?: string,
  options?: {
    labelBg?: string | number;
    messageBg?: string | number;
    labelColor?: string | number;
    messageColor?: string | number;
    labelStyle?: string;
    messageStyle?: string;
    labelWidth?: number;
    messageWidth?: number;
    link?: string;
    forceLink?: boolean;
    theme?: string;
    swapTheme?: boolean;
  }
): string;

Available Options

Option Description Type Default
messageBg Background color for the label string or number blue
labelBg Background color for the message string or number blackBright
messageColor Text color for the message string or number white
labelColor Text color for the label string or number white
labelWidth Width of the label number label length + 2
messageWidth Width of the message number label length + 2
labelStyle Style for the label text string null
messageStyle Style for the label text string null
link Add a link when a badge is clicked (only works in some terminals, see this) URL null
forceLink Force adding link even if not supported boolean false
theme Theme to be used, see all themes string blue
swapTheme Swap the theme, this means properties from label will be aplied to message and vice versa boolean false

Colors

cli-badges uses cli-color internally for managing colors, you can check the list of available colors there. Take into account that when setting a color you don't need to pass the prefix bg, it's handled for you. ie: blackBright instead of bgBlackBright

Xterm colors

There are more colors available using xterm colors, see cli-color xterm colors for the complete list of available colors.

Not supported on Windows and some terminals. However if used in not supported environment, the closest color from basic (16 colors) palette is chosen.

Styles

cli-badges uses cli-color internally for managing styles, you can check the list of available styles there.

Styles will display correctly if font used in your console supports them.

Links

You can output badges with a link attached to it, that can be clicked in some terminals.

⚠︎ cli-badges will only output link if its supported by your terminal.

See this for information on supported terminals

badge('with', 'link', { link: 'https://link.com' });

Themes

Themes are a way to store badge configuration for repeated use. All the options (except for the theme option, obviously) that are needed by the badge can be stored by making a theme.

The library comes with a set of inbuilt themes:

Inbuilt Themes

  • red : Red Message Background
  • green : Green Message Background
  • blue : Blue Message Background
  • yellow : Black Colored Message on Yellow Background
  • cyan : Black Colored Message on Cyan Background
  • magenta : Black Colored Message on Magenta Background
  • success : ('Success') Message on Green Background
  • failed : ('Failed') Message on Red Background

Using Themes

You can use the themes in various ways, passing an option theme to badge:

badge('label', 'green', { theme: 'green' });
badge('label', 'magenta', { theme: 'magenta', swapTheme: true });

Or there are helper methods for ease of use:

badge.green('label', 'green');
badge.failed('theme', 'red');

Options present in the theme will override options passed. Missing options will have default values.

Adding a theme

You can also add you own themes:

badge.addTheme('donate', {
  label: '❤️ donate',
});

badge('', 'ko-fi', { theme: 'donate' });
badge.donate('', 'ko-fi');

You can also send in a PR and suggest a new inbuilt theme :)

Swap Properties

You can also swap all themes, this means properties from label will be aplied to message and vice versa.

badge.failed('theme', 'red');
badge.failed.swap('theme', 'red');

You can check the complete list of themes here.
