How to protect .js from download

Hi everybody.

I have a .js file in one website, I don't want that this file can be downloaded or be shown in the source code of the file.

I tried to protect the folder by an .htaccess file, with this solution i see that even the website can not use the script.

Someone have an idea ??

Thanks for your reply.
Regards.

 

If a site uses a script, it has to download it; once downloaded it can always be accessed.

 

You can only encode .js-file, because javascript runs on client side but not server side.

 

would it be possible to use something server-side instead of java? php or so?

 

Javasource is a Client Side scripting language. This means that it must be downloaded to the viewers computer to be compiled and run. You can use things such as AJAX to pass data between server side languages such as PHP and javascript, to keep security and interactivity balanced.

 

Try use referer check,but here only forbid direct to download,if the man use tool,here still can't work ok!

 

Try:

it just puts all the lines on the same line, that just slows them down about... 20 seconds

 

Nonsense. It hardly slows it down at all. I use Packer on all of my scripts. If it slows down your script by 20 seconds, then your script needs some serious rewriting - it's not the tool that is to blame.

To answer the OP's question: it cannot be done. Lots of people have tried lots of ridiculous things, but Javascript can only be obfuscated. Obfuscated code can quickly and easily be converted into the original source code.

 

It will only slow down the people trying to get the code about 20 seconds, it will not slow down the scripts.

 

Ah... now I understand, and completely agree.

 

you can encode it instead of hiding

Javascript coders programs are available ,they just make it unreadable
