checkout in project svn node / gulp

Hello, could anyone tell me how I can checkout a svn project with node / gulp?

Currently I have this routine that copies my project folder and creates a new one so I can minify the files and then upload to production. I want to change it so it takes the files directly from the svn repository.

    gulp.task('copy', ['clean'], function(){
    return gulp.src([projectName + '//**', 
        '!' + projectName + '/app/{config,config/**}', 
        '!' + projectName + '/app/{storage,storage/**}',
        '!' + projectName + '/{nbproject,nbproject/**}',
        '!' + projectName + '/{Scripts,Scripts/**}'
        ])
        .pipe(gulp.dest('version-client'));
});
