What does it do?

This package sets up common requirements for running an Express app in production with the goal of reducing boilerplate in your applications. Here is a list of some of those things:

• 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
