uglify not working in gulp for js files

Question

I used for the js file but it didn't work. I used same scenario for the minimize css file. It works properly. How can I overcome that problem?

gulp.task('buildApp',['copyAll'],function(){ //concatenate js files to buildApp
    return gulp.src(paths.js)
        .pipe(depsOrder())
        .pipe(concat('app.js'))
        .pipe(uglify())
        .pipe(rename('app.min.js'))
        .pipe(gulp.dest(paths.buildAppconcat))

});

Any error message? What output do you get in your destination directory? — Scott M.

Did you try to output the concatenated file before uglifying it? — DavidDomain

It's seems that you want to save two files app.js and app.min.js. For this scenario you could do the following:

gulp.task('buildApp',['copyAll'],function(){ //concatenate js files to buildApp
return gulp.src(paths.js)
    .pipe(depsOrder())
    .pipe(concat('app.js'))
    .pipe(gulp.dest(paths.buildAppconcat))
    .pipe(rename('app.min.js'))
    .pipe(uglify())
    .pipe(gulp.dest(paths.buildAppconcat))

});
