Mangle all variables except one with gulp-uglify

Question

Is there a way to mangle all variables except a specific one with gulp-uglify?

Answer 1

There definitely is, I couldn't find any documentation for gulp-uglify regarding these sub-options, so relied on grunt-uglify & wrote it the gulp way.

.pipe( uglify({ mangle: {except: ['jQuery']} }) ) // for gulp-uglify ^2.0.1

The above code will mangle every variable except jQuery

Hopefully this will still be useful for you. ;)

NB: If you are using gulp-uglify ^3.0.0 please replace except with reserved eg:

.pipe( uglify({ mangle: {reserved: ['jQuery']} }) ) // for gulp-uglify ^3.0.0
