Duplicate Literals Removal replaces duplicate literals with a single variable name.
"duplicateLiteralsRemoval"
true/false/0-1
Duplicate Literals Removal transforms the code. Try it out by changing the input code and see changes apply in real-time.
// Input.js
var myBool1 = true;
var myBool2 = true;
console.log(myBool1 === myBool2); // true
// Output.js
const uBnisL8 = [!0];
var KbhWCr = uBnisL8[0],
Km734I = uBnisL8[0];
console.log(KbhWCr === Km734I);
input.js and write the output to a file named output.js.
import JSConfuser from "js-confuser";
import {readFileSync, writeFileSync} from "fs";
// Read input code
const sourceCode = readFileSync("input.js", "utf8");
const options = {
target: 'browser',
duplicateLiteralsRemoval: true,
};
JSConfuser.obfuscate(sourceCode, options).then((result)=>{
// Write output code
writeFileSync("output.js", result.code);
}).catch(err=>{
// Error occurred
console.error(err);
});
