gulp watch + sass + browsersync error handing.js

gulp.task('css-browsersync', function() {
    return gulp.src(["*.scss"])
        .pipe(sass().on('error', function(err) {
            console.error(err.message);
            browserSync.notify(err.message, 3000); // Display error in the browser
            this.emit('end'); // Prevent gulp from catching the error and exiting the watch process
        }))
        .pipe(gulp.dest("public/"))
        .pipe(browserSync.stream());
});


gulp.task('watch', ['css-browsersync'], function() {
    browserSync.init({
        server: "./public"
    });

    gulp.watch("*.scss", ['css-browsersync']);
    gulp.watch("public/*.html").on('change', browserSync.reload);
    
    // protip: stop old version of gulp watch from running when you modify the gulpfile
    gulp.watch("gulpfile.js").on("change", () => process.exit(0)); 
});

Thanks bro
