Browser-sync (under gulp) doesn't refresh browser

My config does everything it's supposed to, but it never refreshes the browser. Once I refresh it manually, changes are there. I am connecting to the default localhost:3000. Any ideas why is it so or how to debug it?

gulpfile.js:

var gulp = require('gulp');
var sass = require('gulp-sass');
var sourcemaps = require('gulp-sourcemaps');
var browserSync = require('browser-sync');

gulp.task('html', function () {
    browserSync.reload();
});

gulp.task('sass', function() {
  return gulp.src('./app/scss/style.scss')
    .pipe(sass())
    .pipe(gulp.dest('./app/css'))
    .pipe(browserSync.reload({ stream:true }));
});

gulp.task('serve', function() {
  browserSync({
    server: {
      baseDir: 'app'
    }
  });
});

gulp.task('default', ['serve'], function () {
    gulp.watch('./app/scss/*.scss', ['sass', browserSync.reload]);
    gulp.watch('./app/*.html', ['html', browserSync.reload]);

});

example of a console output: 

[BS] Local URL: http://localhost:3000
[BS] External URL: http://192.168.1.3:3000

Solution

  • I figured it out: browser-sync doesn't like implicit html tags, so this (although valid HTML5) will not work: 

    <!doctype html>
<title>implicit</title>

    but this will: 

    <!doctype html>
<html>
    <head>  
        <title>full doc</title>
    </head>
    <body></body>
</html>
