gulp-auto-reload

Adds (simple) automatic browser reloading to gulp.

The plugin uses WebSocket technology to pass compile events to browser.

Derived from Paul Miller's auto-reload-brunch

Installation

Install the plugin via npm with npm install --save-dev gulp-auto-reload.

Usage

var gulp       = require('gulp');
var concat     = require('gulp-concat');
var autoReload = require('gulp-auto-reload');

// some paths to build from
var paths = {
  html: "src/**/*.html",
  css: "src/**/*.css"
};

// the output
var outapp = "dist";

// this transformer is used to inject <script>
// tags into the html when reloader is enabled
var htmlInject = function() {
  return gutil.noop();
};

gulp.task('html', function() {
  gulp.src(paths.html)
    .pipe(htmlInject())      // inject <script>
    .pipe(gulp.dest(outapp));
});

gulp.task('css', function() {
  gulp.src(paths.css)
    .pipe(concat('ui/app.css'))
    .pipe(gulp.dest(outapp));
});

gulp.task('reloader', function() {
  // start a server for reloading
  var reloader = autoReload();
  // copy the auto-reload.js script to
  // the output
  reloader.script()
    .pipe(gulp.dest(outapp));
  // inject the script into html pages
  htmlInject = reloader.inject;
  // start watching the output for changes
  gulp.watch(outapp + "/**/*", reloader.onChange);
});

// building html/css causes no <script> injection
gulp.task('default', ['html', 'css']);

// 'reloader' sets htmlInject, and 'html' task will
// make injected html page
gulp.task('watch', ['reloader', 'html'], function() {
  // watch all source for rebuild
  gulp.watch('./src/**/*', ['default']);
});

Details

autoReload() starts a server process that listens for websockets on port 9485. On a changed file, the server emits either a 'page' or 'stylesheets' event to all connected clients.

auto-reload.js should be loaded in the client browser. It connects to the server and performs page or stylesheets reload.
