配图 - DevDash 是基于 Terminal 的仪表板

示例 - slash

const path = require('path');
const slash = require('slash');

const string = path.join('foo', 'bar');
// Unix    => foo/bar
// Windows => foo\\bar

slash(string);
// Unix    => foo/bar
// Windows => foo/bar

示例 - commander

const program = require('commander');

program
  .option('-d, --debug', 'output extra debugging')
  .option('-s, --small', 'small pizza size')
  .option('-p, --pizza-type <type>', 'flavour of pizza');

program.parse(process.argv);

if (program.debug) console.log(program.opts());
console.log('pizza details:');
if (program.small) console.log('- small pizza size');
if (program.pizzaType) console.log(`- ${program.pizzaType}`);
