Gulp image-min - How to continue after an error?

Question

I am trying to run an image optimisation task on a folder with 1000s of images, unfortunately some of them are corrupted so the task keeps failing

I have tried to capture the error and continue, but its not working once it hits a corrupted image the task then aborts. Is there a way for this to continue running?

gulp.task('imgCompress', (done) => {
  gulp.src(imgMedia)
    .pipe(imagemin([
       mozjpeg({
         quality: 75
       }),

       pngquant({
         quality: [0.65, 0.80]
       })
    ]))

    .on('error', gutil.log)

    .pipe(gulp.dest(imgMediaDest))
    done();
});

Error:

{ Error: write EPIPE
    at WriteWrap.afterWrite [as oncomplete] (net.js:789:14)
  errno: 'EPIPE',
  code: 'EPIPE',

You should be fine with gulp-plumber, which lets the stream continue after an error and even has an option to log error messages automatically without handling error events.

Also note that you should not call done after creating a stream, but after the stream has terminated (you could for example listen to finish events). But it's easier to simply return the stream from the task function.

const plumber = require('gulp-plumber');

gulp.task('imgCompress', () => {
  return gulp.src(imgMedia)
    .pipe(plumber({ errorHandler: true }))
    .pipe(imagemin([
       mozjpeg({
         quality: 75
       }),

       pngquant({
         quality: [0.65, 0.80]
       })
    ]))
    .pipe(gulp.dest(imgMediaDest))
});
