I’m working on a mvc application (applies to any website though) and was wondering is it ok to leave exposed jquery and javascript in a view? In other words when i run the program and right click and view source I can see all my jquery and javascript. Is that safe and ok? Is there a way to hide all of that so users can’t see that? Thanks for any tips.
There is no way of hiding javascript completely from the user. JavaScript is a client side technology. It executes in the browser. If the browser can execute the script, it can also show it to the user.
You can use JavaScript obfuscator software to make the code harder to read, but you can never hide it completely. See http://www.javascriptobfuscator.com/default.aspx for an online example of this.
JQuery and other libraries are also publicy available so there is no harm in the user being able to access it. There is nothing secret about them.
If you have secrets in the code that you want to protect, you should think about putting the affected code on the server if possible instead of doing the processing on the client.
