Key features:
variables renaming
strings extraction and encryption
dead code injection
control flow flattening
various code transformations
and more ...

Huge thanks to all supporters!
NOTE! the README on the master branch might not match that of the latest stable release! FAQ ⚠️ ImportantIt is not recommended to obfuscate vendor scripts and polyfills, since the obfuscated code is 15-80% slower (depends on options) and the files are significantly larger.
Install the package with Yarn or NPM and add it to your dependencies or devDependencies:
$ yarn add --dev javascript-obfuscator or
$ npm install --save-dev javascript-obfuscator From CDN:

*/ obfuscate(sourceCode, options)Returns ObfuscationResult object which contains two public methods:
getObfuscatedCode() - returns string with obfuscated code;getSourceMap() - if sourceMapstring with source map or an empty string if sourceMapModeinline;getIdentifierNamesCache() - returns object with identifier names cache if identifierNamesCache option is enabled, null overwise.
Calling toString() for ObfuscationResult object will return string with obfuscated code.
Method takes two parameters, sourceCode and options – the source code and the options respectively:
sourceCode (string, default: null) – any valid source code, passed as a string;options (Object, default: null) – an object with options.
For available options, see options .
obfuscateMultiple(sourceCodesObject, options)Accepts sourceCodesObject that is a map which keys are identifiers of source codes and values are source codes:
{
foo: 'var foo = 1;',
bar: 'var bar = 2;'
}
Returns a map object which keys are identifiers of source codes and values are ObfuscationResult objects.
getOptionsByPreset(optionsPreset)Returns an options object for the passed options preset name.
See CLI options .
Usage:
javascript-obfuscator input_file_name.js [options]
javascript-obfuscator input_file_name.js --output output_file_name.js [options]
javascript-obfuscator input_file_name.js --output output_folder_name [options]
javascript-obfuscator input_folder_name --output output_folder_name [options] Obfuscation of single input file with .js extension.
If the destination path is not specified with the --output option, the obfuscated file will be saved into the input file directory, with INPUT_FILE_NAME-obfuscated.js name.
Some examples:
javascript-obfuscator samples/sample.js --compact true --self-defending false
// creates a new file samples/sample-obfuscated.js
javascript-obfuscator samples/sample.js --output output/output.js --compact true --self-defending false
// creates a new file output/output.js Usage:
javascript-obfuscator ./dist [options]
// creates a new obfuscated files under ` ./dist` ` obfuscated` ` ./dist/obfuscated` Obfuscation of all .js files under input directory. If this directory contains already obfuscated files with -obfuscated postfix - these files will ignored.
Obfuscated files will saved into the input directory under INPUT_FILE_NAME-obfuscated.js name.
Conditional comments
You can disable and enable obfuscation for specific parts of the code by adding following comments:
disable: // javascript-obfuscator:disable or /* javascript-obfuscator:disable */;
enable: // javascript-obfuscator:enable or /* javascript-obfuscator:enable */.
Example:
// input
var foo = 1 ;
// javascript-obfuscator:disable
var bar = 2 ;
// output
var _0xabc123 = 0x1 ;
var bar = 2 ; Conditional comments affect only direct transformations of AST-tree nodes. All child transformations still will be applied to the AST-tree nodes.
For example:
Obfuscation of the variable's name at its declaration is called direct transformation;
Obfuscation of the variable's name beyond its declaration is called child transformation.
Kind of variables of inserted nodes will auto-detected, based on most prevailing kind of variables of source code.
During obfuscation of the different files, the same names can be generated for the global identifiers between these files.
To prevent this set the unique prefix for all global identifiers for each obfuscated file with identifiersPrefix
When using CLI this prefix will be added automatically.
