Boot

The boot file, optionally located at ./src/config/boot.js, is a way to "bootstrap" your application before the the application is setup & the server is started. The file must export a method that takes the config & logger:

// ./src/config/boot.js

module.exports = (config, logger) => {
  require('./cache').ensureWarm()
  console.log("All booted up!")
}

This method can be async or plain old synchronous and is run before almost every other part of the application. If you don't need to run logic at startup, you can omit this file.
