yargs is an easy way to write a command line parser

Example:

yargs(hideBin(process.argv))
  .command('serve [port]', 'start the server', (yargs) => {
    return yargs
      .positional('port', {
        describe: 'port to bind on',
        default: 5000
      })
  }, (argv) => {
    if (argv.verbose) console.info(`start server on :${argv.port}`)
    serve(argv.port)
  })
  .option('verbose', {
    alias: 'v',
    type: 'boolean',
    description: 'Run with verbose logging'
  })
  .parse()

Schedule a meeting with me to agree on some consistency for arg parsing

AC:

• Move all scripts to yargs instead of (pass-by-env + handwritten enforcement)
