Add progress bar

[fuzzbuck]

Add 'progress' to Options, which displays a visual progress bar of the obfuscation process in STDOUT

Example:

JsConfuser.obfuscate(contents, {
    target: "browser",
    progress: true,
    preset: "high"
})

[MichaelXF]

This could be implemented using the JsConfuser.debugObfuscation, the same method the js-confuser.com uses to display a progress bar. This way you can avoid the extra dependency. Here's an example:

var outputObject = await JsConfuser.debugObfuscation(
  CODE,
  {
    target: "node",
    preset: "high"
  },
  (transformName, index, totalTransforms) => {
    console.log(transformName + " is done!", index, "/", totalTransforms);
  },
  require("perf_hooks").performance
);

var output: string = outputObject.obfuscated; // The obfuscated code

console.log(outputObject.transformationTimes); // Object of transformation times

cli-progress is a very small library and providers helpers for repeatedly updating stdout, I think there is no need to reinvent the wheel here

[MichaelXF]

This is not planned. You must interface with the custom callback option and feed that into the progress bar library. This is because JS-Confuser.com cannot use system packages.
