obfuscate js using cli

I use javascript-obfuscator package, it works fine if I do operations with files, like: javascript-obfuscator source.js but I need to dynamically change js source content and get output on console in way like javascript-obfuscator "var foo = 'bar'; alert(foo);" Any suggestion how can I get rid from saving content to file and do it like in snippet above?

Not really considering why you'd need to do this, it looks like you'll need to use the programmatic API as described in the library's README.

Let's call this obfuscate.js:

var JavaScriptObfuscator = require('javascript-obfuscator');
var obfuscationResult = JavaScriptObfuscator.obfuscate(
    process.argv[2],
    {
        compact: false,
        controlFlowFlattening: true
    }
);

console.log(obfuscationResult.getObfuscatedCode());

$ node obfuscate.js 'console.log(1)'

will then output (for example)

var _0x2b5a = ['log'];
(function (_0x630038, _0x2944a9) {
    var _0x83df37 = function (_0x2ef1a5) {
        while (--_0x2ef1a5) {
            _0x630038['push'](_0x630038['shift']());
        }
    };
    _0x83df37(++_0x2944a9);
}(_0x2b5a, 0xd7));
var _0x493b = function (_0x2b48eb, _0x33884a) {
    _0x2b48eb = _0x2b48eb - 0x0;
    var _0x41338b = _0x2b5a[_0x2b48eb];
    return _0x41338b;
};
console[_0x493b('0x0')](0x1);
