.nuxt directory is generated in development
Nuxt uses the .nuxt/ directory in development to generate your Vue application. The whole directory will be re-created when running `nuxt dev`, so you should not manually edit any files inside it.
Server plugins execute once when Nitro starts
Nitro plugins are executed only once when the server starts from the /server/plugins directory. In a serverless environment, the server boots on each incoming request, and so do the Nitro plugins, but they are not awaited.
Server plugins capabilities
Nitro plugins can capture and handle application-wide errors, register hooks that execute when Nitro shuts down, and register hooks for request lifecycle events such as modifying responses.
