CLI Helpers

Helper functions to build CLI tools.

Installation

This package is built with TypeScript and is meant to be used in TypeScript projects, but a JavaScript version is built so you can use it in node.js environment.

To install it, you need to use yarn or npm:

yarn add @cnamts/cli-helpers
# OR
npm install @cnamts/cli-helpers

Usage

You can import the different helpers from the main file:

import { log, done, getPath } from '@cnamts/cli-helpers';

Or you can import them using their files, like so:

import { log, done } from '@cnamts/cli-helpers/src/logger';
import { getPath } from '@cnamts/cli-helpers/src/getPath';

Helpers

colors

Get an object with standardized colors.

import { colors } from '@cnamts/cli-helpers';

console.log(colors.primary); // Use 'primary' color

getPath

Get path relative to current working directory.

import { getPath } from '@cnamts/cli-helpers';

const myPath = getPath('./file'); // Equivalent to path.join(process.cwd(), './file)

traceLine

Trace a straight line across the terminal using box-drawing character ─, by default it uses the primary color from colors, but you can change it.

import { traceLine } from '@cnamts/cli-helpers';

traceLine(); // Example: ───────────────────────

traceLine('#eee') // With custom color

logger

Log informations to the user such as errors, warnings, events and others.

import { log, cmd, info, done, warn, error, verbose, event } from '@cnamts/cli-helpers';

log('Default log');
cmd('yarn lint');
info('Info log');
done('Success log');
warn('Warning log');
error('Error log');
verbose('Verbose log');
event('Event log');

renderHeader

Display header with Georgia11 font and optionally author and/or version.
