How to Disable Browser Developer Tools

How to disable browser developer tools?

No you cannot do this.

The developer menu is on the client side and is provided by the user's browser.

Also the browser developer should have nothing to do with your server side database code, and if it does, you need some maaaaaajor restructuring.

How does Facebook disable the browser's integrated Developer Tools?

I'm a security engineer at Facebook and this is my fault. We're testing this for some users to see if it can slow down some attacks where users are tricked into pasting (malicious) JavaScript code into the browser console.

Just to be clear: trying to block hackers client-side is a bad idea in general;
this is to protect against a specific social engineering attack.

If you ended up in the test group and are annoyed by this, sorry.
I tried to make the old opt-out page (now help page) as simple as possible while still being scary enough to stop at least some of the victims.

The actual code is pretty similar to @joeldixon66's link; ours is a little more complicated for no good reason.

Chrome wraps all console code in

with ((console && console._commandLineAPI) || {}) {
  <code goes here>
}

... so the site redefines console._commandLineAPI to throw:

Object.defineProperty(console, '_commandLineAPI',
   { get : function() { throw 'Nooo!' } })

This is not quite enough (try it!), but that's the
main trick.

Epilogue: The Chrome team decided that defeating the console from user-side JS was a bug and fixed the issue, rendering this technique invalid. Afterwards, additional protection was added to protect users from self-xss.

How do I disable opening DevTools in the browser when running expo start?

It's odd that it tells you to use the command before you're actually able to use it.
