Sublime 3: Is there a way to remove tabs/spaces from empty lines?

Question

I am looking for a way to force Sublime 3 to remove all spaces and tabs from any indented line that is empty in my code, either when I save the file or as I am typing.

Is there a way?

    |
    some code
    |
}

if (...) {
|
    some code
|
}

Add this to your preferences (Preferences > Settings):

"trim_trailing_white_space_on_save": true

This will remove whitespaces from the end of all lines, even empty ones, when you save the file.

Quoting the default settings file:

// Set to true to removing trailing white space on save
"trim_trailing_white_space_on_save": false,
