you can saw the connect-livereload already contained.

Usage

we get a connect object, it help us to serve static web server. default, the web server root is the location of gulpfile.js.

create a js file, named to gulpfile.js, it is the specification name for gulp.

var  gulp = require('gulp'),
  connect = require('gulp-connect');
 
gulp.task('connect', function() {
  // 
  connect.server();
});
 
gulp.task('default', ['connect']);

open browser that your favorited, locate to http://localhost:8080/

default, it support ditionary browser, so you should saw the dictionary.

LiveReload

you should use watch feature with livereload, so you will create watch task for it.

in watch task, when file changed, watch task trigger specification task, in below, it is html task.

var gulp = require('gulp'),
  connect = require('gulp-connect');
 
gulp.task('connect', function() {
  connect.server({
    root: 'app',
    livereload: true
  });
});
 
gulp.task('html', function () {
  gulp.src('./app/*.html')
    .pipe(connect.reload());
});
 
gulp.task('watch', function () {
  gulp.watch(['./app/*.html'], ['html']);
});
 
gulp.task('default', ['connect', 'watch']);

in html task, we reload target files.

Start and stop server

connect.server start the web server, connect.serverClose to close a web server.

gulp.task('jenkins-tests', function() {
  connect.server({
    port: 8888
  });
  // run some headless tests with phantomjs 
  // when process exits: 
  connect.serverClose();
});

Multiple server

var gulp = require('gulp'),
  stylus = require('gulp-stylus'),
  connect = require('gulp-connect');
 
gulp.task('connectDev', function () {
  connect.server({
    root: ['app', 'tmp'],
    port: 8000,
    livereload: true
  });
});
 
gulp.task('connectDist', function () {
  connect.server({
    root: 'dist',
    port: 8001,
    livereload: true
  });
});
 
gulp.task('html', function () {
  gulp.src('./app/*.html')
    .pipe(connect.reload());
});
 
gulp.task('stylus', function () {
  gulp.src('./app/stylus/*.styl')
    .pipe(stylus())
    .pipe(gulp.dest('./app/css'))
    .pipe(connect.reload());
});
 
gulp.task('watch', function () {
  gulp.watch(['./app/*.html'], ['html']);
  gulp.watch(['./app/stylus/*.styl'], ['stylus']);
});
 
gulp.task('default', ['connectDist', 'connectDev', 'watch']);
