Why is Gulp watch constantly processing files?

Question

Node.js

Good day to all! Does gulp watch keep updating files on startup? After all, he should only update and shut up when saving the file?

var gulp   = require('gulp'),
    watch  = require('gulp-watch')
    config = require('../../config');

/*
 * Смотрим за изменениями
 */

gulp.task('watch', function(){
    watch([config.watch.html], function(event, cb) {
        gulp.start('html');
    });
    watch([config.watch.less], function(event, cb) {
        gulp.start('less');
    });
    watch(config.watch.jsInternal, function(event, cb) {
        gulp.start('js-internal');
    });
    watch([config.watch.jsExternal], function(event, cb) {
        gulp.start('js-external');
    });
    watch([config.watch.images], function(event, cb) {
        gulp.start('images');
    });
    watch([config.watch.sprites], function(event, cb) {
        gulp.start('sprites');
    });
    watch([config.watch.fonts], function(event, cb) {
        gulp.start('fonts');
    });
});

Answer 1

I will assume that you save the files in the same place from where you take

var src = '*/**';
gulp.src(src)
  .pipe(somePlugin)
  .pipe(gulp.dest(src));

post gulpfile.js code

But could you publish the task itself in order to more accurately determine the cause?

Answer 3

Show the work of your tasks, what are you calling ('html', 'less', etc.) The jamb lies there.
Example of a work task + watch

gulp.task('default', ['run-beats']);

gulp.task('run-beats', () => {
  gulp.start('clean-css');
  gulp.start('beats-watch-sass');
});

gulp.task('clean-css', () => {
  console.log('Чистим папку app/css/*');
  del(['app/css/**', '!app/css']);
});

gulp.task('beats-sass',  () => {
  console.log('Работы с css файлами в app/css/*');

  return gulp.src('./beats/styles/**/*.scss')           // Какие файлы выбрать
      .pipe(plumber({                                   // обработка ошибок
        errorHandler:  (error) => {
          console.log('Error: ' + error.message);
          this.emit('end');
        }
      }))
      .pipe(sass())                                     // Перевод файлов в sass
      .pipe(autoprefixer({                              // автопрефикс
        browsers: ['> 1%', 'last 10 versions', 'Firefox 5', 'Opera 12', 'ie 8', 'ie 9', 'ie 7']
      }))
      .pipe(gulp.dest('./app/css'))                     // Куда файлы вставить
});

gulp.task('beats-watch-sass', () => {
  console.log('Запускаем отслеживание изменений sass файлов ...');
  gulp.watch('./beats/styles/**/*.scss')
    .on('all', function (event, path) {
      if(event == 'unlink'){
        gulp.start('clean-css');
      }

      gulp.start('beats-sass');
    })
});
