@mhkeller/notify

Install

npm install --save @mhkeller/notify

Usage

Pass an object to the notify function with the following options:

• m — {String} The message.
• v — {String} The value.
• d — {String|String[]|Object} Display options. The display style. Can be a chalk style name, array of chalk styles, the name of a built-in display or a display config.
• k — {Boolean} [false] Whether to show a desktop notification using node-notifier
• error — {Error} Pass an error object to get printed out with console.error for reference.
• x — {Object} An object that will extend the display. This is useful if you're setting a string or an array of string colors in d and you want to extend the display in a quick way.

All of these are optional. If you omit either the message or the value, that part of the notification won't appear. If you omit a display, it will use the default which bolds the value portion.

import notify from '@mhkeller/notify'

notify({ m: 'A notification...', v: 'hello', d: 'magenta' });

Built-in displays

The chalk styles passed to d can be a single string, an array of strings or the name of one of the built-in display styles:

// String
notify({ m: 'A notification...', v: 'hello', d: 'cyan' });

// Array of strings
notify({ m: 'A notification...', v: 'hello', d: ['magenta', 'bold', 'italic', 'underline'] });

// Display name
notify({ m: 'A notification...', v: 'hello', d: 'header' });

Here's the full list of built-in display names:

{
  header: ['blue', 'bold'],
  group: ['magenta', 'bold'],
  task: ['cyan', 'bold'],
  note: ['gray', 'italic'],
  error: {
    messageStyle: 'red',
    desktop: true,
    level: 'error'
  },
  warn: {
    messageStyle: ['yellow', 'bold'],
    level: 'warn'
  },
  change: {
    preString: '\n',
    messageStyle: 'cyan'
  },
  success: ['green', 'bold']
}

Advanced styling

You can also pass a display config object to the d key. Any keys you don't set will be filled in with the default values:

{
  messageStyle: '',
  valueStyle: 'bold',
  preString: '', // A string that goes before the timestamp. Useful if you want to put a line break character '\n'
  postString: '', // Same as pre-string but it gets added to the end
  skipPrefix: false, // Skip the bracketed timestamp + project name portion, called the prefix
  prefixStyle: { // Styling for the prefix
    open: '[',
    close: ']',
    sep: '|',
    timestampStyle: 'gray',
    projectNameStyle: ['blue', 'bold']
  },
  projectName: null, // By default, this is the name of your project directory but you can manually set it to something else here
  time: null, // By default, this is the current time, but you can manually set it to something else here
  desktop: false, // Show a desktop notification
  level: 'log' // Can be 'log', 'warn' or 'error'. Whether the notification gets called through `console.log`, `console.warn` or `console.error`.
