App features

App features are settings that slightly modify app behavior.

Toggle app features​

You can enable, disable and toggle different app features with LunaticServer methods app.enable(), app.disable() and app.toggle() respectively.

import { LunaticServer } from '@shelepuginivan/lunatic'

const app = new LunaticServer()

app.disable('x-powered-by') // disables X-Powered-By header which is set by default

List of app features:​

If you are using TypeScript, you can import type ApplicationFeature:

import { ApplicationFeature } from '@shelepuginivan/lunatic'

Currently, these features are available:

  • 500-on-error - send 500 Internal Server Error status if error occurred during request handling. Enabled by default
  • auto-head-handler - automatically respond to HEAD requests with same headers, but without body and status code 204 No Content. Enabled by default
  • x-powered-by - set response header X-Powered-By: Lunatic. Enabled by default
