How to protect HTML5 games?

Question

JavaScript

Hello.
The question is: How can you secure HTML5 games? How realistic is this?
For example, if you want to write an online casino with real money, would it be wise to use HTML5/JS/any backend? Or still do it in Flash?
Please describe all the details in detail and with arguments. Thank you.

Answer 1

Flash can be decompiled, so you should not rely on the fact that the source code will be protected.
Code, patent, track and sue infringers.
The main functionality can be transferred to the server so that the client part is useless.
Client code can be made poorly readable, obfuscated.

Answer 2

All logic on the server, wins, getting a list of cards, determining the amount to pay, etc. On the client, only visual operations and sending data to the server.

Answer 3

The client should not perform any function other than displaying information. All logic should be on the backend.

Answer 4

Logic should be on the backend. HTML5 is a simple display, you can't break it.

Answer 5

Or you can just use Jscrambler like this: vempiregame.com/allgemein/our-road-to-alpha-i-secu...
