API

meow(options, [minimistOptions])

Returns an Object with:

input (Array) - Non-flag arguments
flags (Object) - Flags converted to camelCase
pkg (Object) - The package.json object
help (string) - The help text used with --help
showHelp([code=2]) (Function) - Show the help text and exit with code
showVersion() (Function) - Show the version text and exit

options

Type: Object Array string

Can either be a string/array that is the help or an options object.

flags

Type: Object

Define argument flags.

The key is the flag name and the value is an object with any of:

type: Type of value. (Possible values: string boolean)
alias: Usually used to define a short flag alias.
default: Default value when the flag is not specified.

Example:

flags: {
unicorn: {
type: 'string',
alias: 'u',
default: 'rainbow'
}
}

description

Type: string boolean
Default: The package.json "description" property

Description to show above the help text.

Set it to false to disable it altogether.

help

Type: string boolean

The help text you want shown.

The input is reindented and starting/ending newlines are trimmed which means you can use a template literal without having to care about using the correct amount of indent.

The description will be shown above your help text automatically.

version

Type: string boolean
Default: The package.json "version" property

Set a custom version output.

autoHelp

Type: boolean
Default: true

Automatically show the help text when the --help flag is present. Useful to set this value to false when a CLI manages child CLIs with their own help text.

autoVersion

Type: boolean
Default: true

Automatically show the version text when the --version flag is present. Useful to set this value to false when a CLI manages child CLIs with their own version text.

pkg

Type: Object
Default: Closest package.json upwards

package.json as an Object.

You most likely don't need this option.

argv

Type: Array
Default: process.argv.slice(2)

Custom arguments object.

inferType

Type: boolean
Default: false

Infer the argument type.

By default, the argument 5 in $ foo 5 becomes a string. Enabling this would infer it as a number.

Promises

Meow will make unhandled rejected promises fail loudly instead of the default silent fail. Meaning you don't have to manually .catch() promises used in your CLI.

Tips

See chalk if you want to colorize the terminal output.

See get-stdin if you want to accept input from stdin.

See conf if you need to persist some data.

See update-notifier if you want update notifications.
