How to generate a source map for files included with require?

Question

JavaScript

We have a gulp task:

gulp.task('js', function() {
    gulp.src('*.js')
        .pipe(sourcemaps.init())
        .pipe(browserify())
        .pipe(sourcemaps.write('./maps/', {includeContent: false}))
        .pipe(gulp.dest('./'));
});

And a js file with something like this:

require('foo.js');
require('bar.js');

//some local code

Source map in this case is created for a concatenated common js file, which includes code from foo.js, bar.js and the file in which they are included. And the lines in the generated source map point to line numbers in that file.
It is necessary that the mapping be on specific final files foo.js and bar.js How can this be done? Perhaps using some other plugins.
