  // Load in your routes
  app.get('/', (req, res) => {
    res.send(`Hello ${opts.message}!`)
  })
})

// Start the app
runApp({
  port: 8080,

  const addr = server.address()
  console.log(`Server started at http://${app.get('host')}:${addr.port}`)
})

What does it do?

这个包设置了在生产中运行 Express 应用程序的通用要求 目标是减少应用程序中的样板文件。 以下是其中一些内容的列表：

• Uses next gen Express (5.0.0-alpha.7 at the time of publishing this)
• See the GitHub PR for 5.0 for details
• New and improved path-to-regex
• Router with basic promise support
• Express app settings
• Remove x-powered-by header
• Sets query string parsing to simple (faster, more secure, planned default for 5.0)
• Set process title (nice for identifying your server process)
• Catch, report and exit on uncaughtException and unhandledRejection
• Handle and report server clientErrors
• Parses JSON bodies
• Parses cookies (off by default, turn on by passing options.parseCookies
