What is nandokujs

nandokujs is an obfuscation tool for obfuscating javascript files to be published on the Web and making it difficult to analyze the contents.

You can make your keycode mandatory for running javascript files, with your own tally code.

In this way, javascript files are obfuscated, so important logic is not exposed to the Web in plain text.

Installation

※ It is assumed that nodejs is installed and npm can be used.

$ npm install -g nandokujs

How to use

The usage can be confirmed by executing the command.

Files obfuscated by nandokujs are output as [js file name].nan.js.

$ nandokujs [js file name] [tally code]
  [js file name]  Set the js file name to be converted.
  [tally code]  Set tally code.
                html side js call (<script src='target js'></script>)に
                  <script> var _$tallyCode = 'tally code'; </script>
                Define.
                If you do not use it, please do not set it.

 Files obfuscated by nandokujs are output as [js file name] .nan.js.

Set the javascript file to be converted to the first argument.

The second argument is optional, but you can set it to a tally code.

In that case, it is necessary to code as follows for the javascript caller to publish on the web.

<script>
  var _$tallyCode = "tally code";
</script>
<script src="target javascript.nan.js"></script>

exsample

Obfuscation with command.

$ nandokujs cbox-min.js test

The following call is described in html using js file.

<script>
  var _$tallyCode = "test";
</script>
<script src="cbox-min.js.nan.js"></script>

Finally

With this tool, I hope to be a good deal for web development.
