TypeScript Obfuscation

Question

Are there any tools or forks of TypeScript to support public namespace obfuscation? I.e. to turn:

class MyUtil {
   print(): void { ... }
}

Answer 1

I had the exact same question, and it was instantly deleted by SO.

https://github.com/angular/ts-minify

This is exactly the tool you (and I) are looking for, it seems to work pretty well, I needed to comment out a few parts where the the author was taking precautions I don't think are applicable.

Answer 2

I don't believe there is any reason to do this in TypeScript. You can instead use something like Closure Compiler to do the obfuscation on your JavaScript output. Specifically look into Closure's Advanced Compilation settings.

Answer 3

 Not a direct answer! Js obfuscator

https://github.com/javascript-obfuscator/javascript-obfuscator

Plugins:

Webpack plugin: webpack-obfuscator
Webpack loader: obfuscator-loader
Gulp: gulp-javascript-obfuscator
Grunt: grunt-contrib-obfuscator
Rollup: rollup-plugin-javascript-obfuscator

NOTE:

Only obfuscate the code that belongs to you.

It 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.
