Prevent errors from breaking / crashing gulp watch

Question

I\'m running gulp 3.6.2 and have the following task that was set up from a sample online

gulp.task(\'watch\', [\'default\'], function () {
  gulp.watch([
            


        

Answer 1

A simple solution to this is to put gulp watch in an infinite loop within a Bash (or sh) shell.

while true; do gulp; gulp watch; sleep 1; done

Keep the output of this command in a visible area on your screen as you edit your JavaScript. When your edits result in an error, Gulp will crash, print its stack trace, wait for a second, and resume watching your source files. You can then correct the syntax error, and Gulp will indicate whether or not the edit was a success by either printing out it's normal output, or crashing (then resuming) again.

This will work in a Linux or Mac terminal. If you are using Windows, use Cygwin or Ubuntu Bash (Windows 10).

Answer 2

The above examples didn't work for me. The following did though:

var plumber = require('gulp-plumber');
var liveReload = require('gulp-livereload');
var gutil = require('gulp-util');
var plumber = require('gulp-plumber');
var compass = require('gulp-compass');
var rename = require('gulp-rename');
var minifycss = require('gulp-minify-css');
var notify = require('gulp-notify');

gulp.task('styles', function () {
    //only process main.scss which imports all other required styles - including vendor files.
    return gulp.src('./assets/scss/main.scss')
            .pipe(plumber(function (error) {
                gutil.log(error.message);
                this.emit('end');
            }))
            .pipe(compass({
                config_file: './config.rb',
                css: './css'
                , sass: './assets/scss'
            }))
            //minify files
            .pipe(rename({suffix: '.min'}))
            .pipe(minifycss())

            //output
            .pipe(gulp.dest('./css'))
            .pipe(notify({message: 'Styles task complete'}));
});

gulp.task('watch', function () {
    liveReload.listen();
    gulp.watch('assets/scss/**/*.scss', ['styles']);
});
