Is the local server required when using Parse?

[CrabDude]

After "Setup" with the following /src/lib/config.js:

module.exports = {
  PARSE: {
    APP_ID: '...',
    REST_API_KEY: '...',
    SESSION_TOKEN_KEY: 'SESSION_TOKEN_KEY'
  },
  backend: {
    parse: true,
    hapiLocal: false,
    hapiRemote: false
  }
}

Running the iOS app in Xcode fails with the following error:

Could not connect to development server.

Ensure the following:
- Node Server is running and available on the same network - run 'npm start' from react-native root
- Node server URL is correctly set in AppDelegate

URL: http://localhosts/index.ios.bundle?platform=ios&dev=true

So, 4 things (EDIT: 5 things):

1. Obviously it's not running, because I thought / it seemed it was possible to run the app using only Parse for the backend.
2. I didn't see anything in "Setup" about updating AppDelegate; I do see mention of it in the "Continuous Integration" steps.
3. The default / original value used in AppDelegate is localhosts. Is that a typo?
4. Is it possibly to run this without the local server using only Parse?
5. Also, switching to the automatically generated "pre-bundled file on disk" results in a successful build, with no error, but a blank (black) screen.

EDIT: Added 5th point above.
EDIT 2: Working just fine with local server AND Parse using localhost:8081 URL in AppDelegate instead of localhosts (assuming the latter is a typo).

It seems the answer is, "Obviously, yes." and that this isn't really the issue I ran into, since the server is started automatically in the Build/Run steps. It's also obviously not mentioned in "Setup" because you don't have to run it manually.

It seems the issue I ran into was just due to the default localhosts instead of localhost:8081 typo, which generated an error message that lead me to believe the server hadn't been started and needed to be started manually.

Closing & opening separate issue for typo.
