| Meow | JavaScript libraries | 2017-10-30 | -1 | [meow](https://npmjs.com/package/meow) is the easiest way to write command line apps for Node.js. |
Typical settings
const cli = require('meow')(`
Usage: appname [options]
Options:
--lang LANG set the language
Other options:
-h, --help show usage information
-v, --version print version info and exit
`, {
string: ['lang'],
boolean: ['help', 'version'],
alias: { h: 'help', v: 'version' }
})
string and boolean lets meow/minimist know which flags expect arguments (string) and which don't (boolean).
Using the result
cli.flags // { lang: 'en' }
cli.input // []
Yes, flags are automatically camelCased!
Lesser-used settings
meow(`...`, {
// Default values if flags are not specified
default: { lang: 'en' },
// allow using -- to stop processing flags
'--': true,
// Populate `_` with first non-option
stopEarly: true,
// Invoked on unknown param
unknown: function () { ... }
})
