Where to find express.js settings

I'm almost ashamed to ask this, but where can I find information about the settings for express.js? According to the documentation I can use app.set(name, setting) to assign setting name to setting, however I can't find anywhere which settings there are and how they work.

You can find it here:

http://expressjs.com/api.html#app-settings

settings

The following settings are provided to alter how Express will behave:

  • env Environment mode, defaults to process.env.NODE_ENV or "development"
  • trust proxy Enables reverse proxy support, disabled by default
  • jsonp callback name Changes the default callback name of ?callback=
  • json replacer JSON replacer callback, null by default
  • json spaces JSON response spaces for formatting, defaults to 2 in development, 0 in production
  • case sensitive routing Enable case sensitivity, disabled by default, treating "/Foo" and "/foo" as the same
  • strict routing Enable strict routing, by default "/foo" and "/foo/" are treated the same by the router
  • view cache Enables view template compilation caching, enabled in production by default
  • view engine The default engine extension to use when omitted
  • views The view directory path
