Error handling in Gulp using `gulp-plumber` and `gulp-notify`

gulpfile.js

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

const plumber_notifier = plumber({
    errorHandler: notify.onError({
        title: "Oops!",
        message: "<%= error.message %>",
    }),
});

// usage
gulp.task('sausage', [], function () {
    return gulp.src('pork/*.part')
        .pipe(plumber_notifier)
        .pipe(make_the_sausage())
        .pipe(gulp.dest('fridge/sausagefile.pack'))
    ;
});
