Gulp sass watch create new css folder

Ihave 2 problems with gulp sass watch
1- when i save my sass file gulp create extra css folder and i already have one
2- gulp watch is only watching for my style.scss and not the other files inside the other folders
My project structure
assets
css
style.css
sass
1-basics
_base.scss
_colors.scss
2-layout
_grid.scss
_header.scss
style.scss
index.html
gulp
const gulp = require('gulp');
const watch = require('gulp-watch');
const sass = require('gulp-sass');
const bs = require('browser-sync').create();
gulp.task('browser-sync', ['sass'], function() {
bs.init({
server: {
baseDir: "./"
}
});
});
gulp.task('sass', function () {
return gulp.src('assets/sass/**/*style.scss')
.pipe(sass())
.pipe(gulp.dest('./assets/css'))
.pipe(bs.reload({stream: true}));
});
gulp.task('watch', ['browser-sync'], function () {
gulp.watch("assets/sass/**/*style.scss", ['sass']);
gulp.watch("*.html").on('change', bs.reload);
});

I modified a few parts of your code, see the comments:
const gulp = require('gulp');
// you are not using the following require, gulp.watch is not the watch plugin below
// it is a function of the gulp object required above
// const watch = require('gulp-watch');
const sass = require('gulp-sass');
const bs = require('browser-sync').create();
gulp.task('browser-sync', ['sass'], function() {
bs.init({
server: {
baseDir: "./"
}
});
// note I moved the watch tasks to within the browser-sync task
// and changed the sass watch glob below
// so it watches both the partials and style.scss
gulp.watch("assets/sass/**/*.scss", ['sass']);
gulp.watch("*.html").on('change', bs.reload);
});
gulp.task('sass', function () {
// this appears to be the correct path to your style.scss file
return gulp.src('assets/style.scss')
.pipe(sass())
// with the change to the gulp.src above, now the gulp.dest is correct
// before you had a globstar ** and that effects the base directory
// that will be used below. Without the globstar it is a little easier
.pipe(gulp.dest('./assets/css'))
.pipe(bs.reload({stream: true}));
});
// moving the watch tasks now allows this simple default task
gulp.task('default', ['browser-sync']));
// below not needed now
//gulp.task('watch', ['browser-sync'], function () {
//gulp.watch("assets/sass/**/*style.scss", ['sass']);
//gulp.watch("*.html").on('change', bs.reload);
//});

Node - An #import loop has been found

I'm new with js, node and all things related.
I'm trying to set up a front end development environment from scratch, using gulp, bower, browser sync, and other plugins.
I'm almost done, it's working in some way, except for a couple of details I can't resolve because I'm not sure if it's something in the code syntax or the order of the functions executed in my gulpfile.js file, or because the plugins are not being used correctly. I have already tried to change the order of them, change some path, etc with no results.
Now I'm experiencing the following issues:
The main.scss needs to be saved two times before see the changes reflected in the browser.
When I run gulp in the console this is what I receive (these errors are new and appeared after a minor change proposed by Poeta in his answer, which helped me a lot.

So, could you please point me in the right direction to get this enviroment set in the proper way?
Update about previous problem: The following was resolved thanks to Bruno Poeta's answer.

Note: the line 526 doesn't exist since it is generated by the gulp-inject plugin. These are the last lines in the main.css file, line 520 and 521:
// inject:app
// endinject

The error as you may have noticed is in your styles task. The problem is that you are importing all .scss files, including main.scss itself. That is your loop, right there. Remove main.scss from the files that should be injected, like this:
gulp.task('styles', function(){
var injectAppFiles = gulp.src(['!src/styles/main.scss', 'src/styles/*.scss'], {read: false});
// ...
It should work right now.

gulpfile.js - task is not in gulp file error

Below is my current Gulpfile.js and when I'm attempting to run gulp minify I'm getting the error, "Task 'minify' is not in your gulpfile". However, I'm able to run gulp sass with no issues. I also have each module installed with npm.
module.exports = function(gulp) {
'use strict'
var sass = require('gulp-sass');
var browserSync = require('browser-sync');
var cssnano = require('gulp-cssnano');
var concat = require('gulp-concat');
var rename = require('gulp-rename');
gulp.task('sass', function() {
return gulp.src('app/scss/**/*.scss')
.pipe(sass())
.pipe(gulp.dest('app/css'))
.pipe(browserSync.reload({
stream: true
}))
});
gulp.task('minify', function() {
return gulp.src('app/css/**/*.css')
.pipe(cssnano())
.pipe(concat('style.min.css'))
.pipe(gulp.dest('app/css/min'))
.pipe(browserSync.reload({
stream: true
}))
});
gulp.task('watch', ['browserSync', 'sass', 'cssnano'], function() {
gulp.watch('app/scss/**/*.scss', ['sass']);
gulp.watch('app/*.html', browserSync.reload);
gulp.watch('app/js/**/*.js', browserSync.reload);
});
gulp.task('browserSync', function() {
browserSync({
server: {
baseDir: 'app/'
},
})
})
}

You should not treat the gulpfile.js as a node module and drop the following part
module.exports = function(gulp) {
(don't forget to remove the closing curly (}) at the end of the gulpfile.js)
Then, you should require gulp
var gulp = require('gulp');
That should make it run smoothly.
Why it does run your gulp sass, I don't know. I just created a simple test file in a fresh directory, and it didn't recognise the sass task for me. Maybe you installedgulp, sass or both globally at some point (e.g. earlier project).

Gulp livereload not working in Chrome

So I am trying to set up the livereload server, however, I never get the message Live reload server listening on: <port_number> like in this video. If I change my files, the console says that the file was reloaded. I have the Chrome extension installed. What am I missing? Thanks.

I use browser-sync to reload the browser when a file has changed.
Try something like this:
var gulp = require('gulp');
var browserSync = require('browser-sync').create();
gulp.task('serve', function() {
gulp.watch("app/**/*.js").on('change', browserSync.reload);
gulp.watch("templates/**/*.html").on('change', browserSync.reload);
gulp.watch("css/**/*.css").on('change', browserSync.reload);
browserSync.init({
server: "./"
});
});
gulp.task('default', ['serve']);

I recommend your attention to the real-time browser page reload tool.

Easy to use. Works independently of the IDE. But you need the IDE to be able to auto-save files. Also works with tools like Gulp, WebPack, Grunt and others.

Gulp-livereload, -webserver and -embedlr. How to use them together?

I try to understand how to use gulp with these useful and popular plugins. There are what I have:
runned go(lang) server on localhost:8000
static/local html files under app folder which are used by server to form pages
scss files under the same directory, which are converted into css and then autoprefixed
Here is my gulpfile.js:
var gulp = require('gulp'),
sass = require('gulp-sass'),
watch = require('gulp-watch'),
autoprefixer = require('gulp-autoprefixer'),
livereload = require('gulp-livereload');
// "./" - it's "app" directory
gulp.task('default', function() {
return gulp.src('./*.scss')
.pipe(watch('./*.scss'))
.pipe(sass())
.pipe(autoprefixer('> 5%'))
.pipe(gulp.dest('./'));
});
So what I need:
watch html, css/scss files for change and make reload on localhost:8000 (chrome's open tab)
it will be great if there is no need to use:
livereload chrome plugin
expressjs framework
reload html pages if it opened directly just like file without server
I've read that it is possible to achieve this by using gulp-embedlr and gulp-webserver. If so, how to do it?

Ok, the best solution that I find is using Gulp + BrowserSync! It's great solution.
Here is the code of my gulpfile.js:
var gulp = require('gulp'),
sourcemaps = require('gulp-sourcemaps'),
sass = require('gulp-sass'),
watch = require('gulp-watch'),
autoprefixer = require('gulp-autoprefixer'),
browserSync = require('browser-sync'),
reload = browserSync.reload;
gulp.task('browserSync', function() {
browserSync({
//logConnections: false,
//logFileChanges: false,
notify: false,
open: false,
server: {
baseDir: "./"
}
});
});
gulp.task('sass', function() {
return gulp.src('./css/*.scss')
.pipe(sourcemaps.init())
.pipe(sass())
.pipe(autoprefixer('> 5%'))
.pipe(sourcemaps.write())
.pipe(gulp.dest('./css'))
.pipe(reload({stream:true}));
});
gulp.task('watch', function() {
gulp.watch('./css/*.scss', ['sass']);
gulp.watch('./*.html', reload);
});
gulp.task('default', ['watch', 'sass', 'browserSync']);
There is no sense to explain the code above. Just read this: http://www.browsersync.io/docs/gulp/
