exit gulp when build is finished

问题

I'm using gulp to minify CSS and JS files.

When I run the gulp command gulp build:website1:desktop from a terminal, it finishes successfully but it does not return to the shell prompt, I have to run Ctrl+C to return to the command prompt

Here is a what I'm using

gulp.task('build:website1:desktop', function () {
runSequence(
    'website1:desktop:scripts',
    'website1:desktop:css');
  })

Any ideas How to exit and return to the command prompt without typing Ctrl+C every time?

Thank you in advance.

回答1:

First thing is to make sure that your scripts and css tasks return a stream or a promise, so that runSequence knows when these tasks are finished. For most gulp tasks, using the return statement with gulp.src(…) will do just that:

gulp.task('website1:desktop:scripts', function() {
  return gulp.src(…)
    .pipe(doSomething())
    .pipe(gulp.dest(…));
});

Next thing is to provide a callback for runSequence:

gulp.task('build:website1:desktop', function (callback) {
  runSequence(
    'website1:desktop:scripts',
    'website1:desktop:css',
    callback);
});

This should do the trick.
