How do you set default `CONNECTION` to `tunnel` with Expo?

Question

When running expo ios, the default connection type is LAN. Via app.json, metro.config.js, or .env, how does one configure type tunnel to be the default?

Did you ever get a solution for this? If so, you should answer your own question for future searchers. — monsto, Feb 12 '21 at 20:18
I didn't :/ I just put up with clicking on 'tunnel' on restarts for the time being. — lovelikelando, Feb 12 '21 at 23:52

It's been a while since you asked this question so I assume you have already figure out the answer. You need to change the "start" script in package.json to "expo start --tunnel".

  "scripts": {
    "start": "expo start --tunnel",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "web": "expo start --web",
    "eject": "expo eject"
  },

I was having the same issue and i tried to change my scripts to:

{
   "scripts": {
    "start": "expo start --tunnel",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "web": "expo start --web"
  }
}

But I didn't work. I then run directly the command:

expo start --tunnel

Then everything worked fine.

Btw, on July 25th, the Expo team announced "Sunsetting the Web UI for Expo CLI".

So, only the commands typed in the terminal stand:

"start": "expo start --tunnel",
"android": "expo start --android",
"ios": "expo start --ios",
"web": "expo start --web",
"eject": "expo eject"

or writing them in the package.jason --> scripts, as @porkupan suggested.
