  5. its not just api key or whatever . what about changing the code? if you make a front page game and you dont wanna put the code in the server what if the client change the rules of the game? for example change the time clock. if you have thousands of users playing simultaneously you dont wanna calculate the time and every movements and the rules in your server

  12. if you want to store this client-side why would you not just set the keys as an environment variable so they accessible to the dev but they are not rendered to the DOM for client-side viewing? Can someone help me understand where my logic is wrong here so that I can improve this in the future? -Thank you

  13. this video has everything to do with the title. i got an answer to something that was bothering a lot on watching this the 3rd time. i dont know why i didn't get it before. i think people who are into spa will find that the title of the video goes well with the content (since i noticed some comments about title and content )

  18. So essentially run a server-side app and use environmental variables. Then create an api for your js frontend to interface with. You can configure your own permissions on the user by coding them yourself since its your api. Mern stack + typescript it is.

  22. Here's my tip:
    a) search for a web site that ulgify js code.
    b) back up all your js files

    c) ulgify all your js files
    d) deploy the uglified version of your files, .gitignore your jsFilesBackup
    Be happy.

  23. You almost answered my exact question! I have a Vue front end, with a Django backend (all running off the same host & port (proxied), using sessions). As it stands, a user can get full access to the front-end of the system by faking a login on the client-side, i.e. flipping a 'loggedIn' boolean. They will not get any data, but they will see the full UI, and I don't think I want this. How can that be prevented?

  37. If JavaScript was hidden or even encrypted at client browsers, there would be hardly any websites today. If you wanna hide stuff, hide it in your backend service layer where you can put your business logic. If you're a frontend developer and frustrated, then you can't do anything about it. Just let it go or work with your backend teammate on a solution. If you're a fullstack developer or freelancer or hobbyist, it's all in your hands. You're the commander of what to show and what not to show.
