yargs with command

require('yargs')
    .usage('Usage: $0 <command> [arguments]')
    .help('h')
    .alias('h', 'help')
    .version(require(__dirname+'/package.json').version)
    .strict()
    .wrap(null)
    .demandCommand(1, 'Please choose a command')
    .command(
        'create',
        "create something",
        (yargs) => {
            yargs.example('$0 create');
            yargs.option('verbose', {
                alias: 'v',
                describe: 'print progress informations',
            })
        },
        function(argv) {
            console.log('success')
        }
    )
    .argv;

yargs with command in directory

create a file named : cli.js

    #!/usr/bin/env node
    require('yargs')
        .commandDir('commands')
        .demandCommand()
        .help()
        .argv

create a file : commands/init.js

    exports.command = 'init [dir]'
    exports.desc = 'Create an empty repo'
    exports.builder = {
        dir: {
            default: '.'
        }
    }
    exports.handler = function (argv) {
        console.log('init called for dir', argv.dir)
    }
