How to handle 'code generator has deoptimised styling' message from gulp-babel

问题

I've just employed gulp-babel to my gulp file with the following

var babel = require('gulp-babel');

return gulp.src(files.concat.js.myModule)
  .pipe(babel())
  .pipe(concat('myModule.js'))
  .pipe(gulp.dest('path/to/js'));

...and I get the following Note about deoptimising the styling in my gulp output:

NOTE: The code generator has deoptimised the styling ... as it exceeds the max of "100KB"

Is this a problem?
Should I be handling this is some way?

回答1:

Turns out the compact option is set to auto by default which removes "superfluous whitespace characters and line terminators [...] on input sizes >100KB".

If this is not what you want, you can set the compact option to false...

.pipe(babel({compact: false}))
