Gulp Concat no output file

Question

I am trying to concatinate my js files with gulp's concate module.

My projects path to js files is: project/public/js/vendor/.

In vendor are all the plugins I use and I want to concatinate them to a single file

I use the following code to execute my task.

var gulp = require('gulp'),
concat = require('gulp-concat');

gulp.task('scripts',function(){
    return gulp.src('./vendor/*.js')
        .pipe(concat('global.js'))
        .pipe(gulp.dest('concat/'));

});

gulp.task('default', ['scripts']);

I want to export the file to concat folder which is located into /js, but I get no file. The code executes with no error report.

[gulp] Using gulpfile /var/www/vhosts/site.dev/httpdocs/project/gulpfile.js
[gulp] Starting 'scripts'...
[gulp] Finished 'scripts' after 9.2 ms
[gulp] Starting 'default'...
[gulp] Finished 'default' after 8.8 μs

Did I do something wrong?

Edit 1

I tried to log the count as it was suggested and returned:

[gulp] Using gulpfile /var/www/vhosts/site.dev/httpdocs/laravel/gulpfile.js
[gulp] Starting 'scripts'...
[gulp] Finished 'scripts' after 12 ms
[gulp] Starting 'default'...
[gulp] Finished 'default' after 9.37 μs

Does this means that it didn't select any js?

Answer 1

mostly there are not source files being selected, use gulp-count to print the number of files selected

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

gulp.task('scripts',function(){
    return gulp.src('./vendor/*.js')
        .pipe(count('## js-files selected'))
        .pipe(concat('global.js'))
        .pipe(gulp.dest('concat/'));

});

if you get count as 0, given your path is project/public/js/vendor/ change your gulp.src to gulp.src('project/public/js/vendor/**/*.js')
