node-livereload

Build status

An implementation of the LiveReload server in Node.js. It's an alternative to the graphical http://livereload.com/ application, which monitors files for changes and reloads your web browser.

Usage

You can use this by using the official browser extension or by adding JavaScript code to your page.

Method 1: Use Browser Extension

Install the LiveReload browser plugins by visiting http://help.livereload.com/kb/general-use/browser-extensions.

Note: Only Google Chrome supports viewing file:/// URLS, and you have to specifically enable it. If you are using other browsers and want to use file:/// URLs, add the JS code to the page as shown in the next section.

Once you have the plugin installed, start livereload. Then, in the browser, click the LiveReload icon to connect the browser to the server.

Method 2: Add code to page

Add this code:

<script>
  document.write('<script src="http://' + (location.host || 'localhost').split(':')[0] +
  ':35729/livereload.js?snipver=1"></' + 'script>')
</script>

Note: If you are using a different port other than 35729 you will need to change the above script.

Running LiveReload

You can run LiveReload two ways: using the CLI application or by writing your own server using the API.

Method 1: Using the Command line Interface

To use livereload from the command line:

$ npm install -g livereload
$ livereload [path]

The commandline options are

  • -p or --port to specify the listening port
  • -d or --debug to show debug messages when the browser reloads.
  • -e or --exts to specify extentions that you want to observe. Example: -e 'jade,scss'. Removes the default extensions.
  • -ee or --extraExts to include additional extentions that you want to observe. Example: -ee 'jade,scss'.
  • -x or --exclusions to specify additional exclusion patterns. Example: -x html, images/.
  • -u or --usepolling to poll for file system changes. Set this to true to successfully watch files over a network.
  • -w or --wait to add a delay (in miliseconds) between when livereload detects a change to the filesystem and when it notifies the browser.

Specify the path when using the options.

$ livereload . -w 1000 -d

Option 2: From within your own project

To use the api within a project:

$ npm install livereload --save

Then, create a server and fire it up.

var livereload = require('livereload');
var server = livereload.createServer();
server.watch(__dirname + "/public");

You can also use this with a Connect server. Here's an example of a simple server using connect and a few other modules just to give you an idea:

var connect  = require('connect');
var compiler = require('connect-compiler');
var static = require('serve-static');

var server = connect();

server.use(
  compiler({
      enabled : [ 'coffee', 'uglify' ],
      src     : 'src',
      dest    : 'public'
  })
);

server.use(  static(__dirname + '/public'));

server.listen(3000);

var livereload = require('livereload');
var lrserver = livereload.createServer();
lrserver.watch(__dirname + "/public");

You can then start up the server which will listen on port 3000.

Server API

The createServer() method accepts two arguments.

The first are some configuration options, passed as a JavaScript object:

  • https is an optional object of options to be passed to https.createServer (if not provided, http.createServer is used instead)
  • port is the listening port. It defaults to 35729 which is what the LiveReload extensions use currently.
  • exts is an array of extensions you want to observe. This overrides the default extensions of [html, css, js, png, gif, jpg, php, php5, py, rb, erb, coffee].
  • extraExts is an array of extensions you want to observe. The default extensions are [html, css, js, png, gif, jpg, php, php5, py, rb, erb, coffee].
  • applyCSSLive tells LiveReload to reload CSS files in the background instead of refreshing the page. The default for this is true.
  • applyImgLive tells LiveReload to reload image files in the background instead of refreshing the page. The default for this is true. Namely for these extensions: jpg, jpeg, png, gif
  • exclusions lets you specify files to ignore. By default, this includes .git/, .svn/, and .hg/
  • originalPath Set URL you use for development, e.g 'http:/domain.com', then LiveReload will proxy this url to local path.
  • overrideURL lets you specify a different host for CSS files. This lets you edit local CSS files but view a live site. See http://feedback.livereload.com/knowledgebase/articles/86220-preview-css-changes-against-a-live-site-then-uplo for details.
  • usePolling Poll for file system changes. Set this to true to successfully watch files over a network.
  • delay add a delay (in miliseconds) between when livereload detects a change to the filesystem and when it notifies the browser. Useful if the browser is reloading/refreshing before a file has been compiled, for example, by browserify.
  • noListen Pass as true to indicate that the websocket server should not be started automatically. (useful if you want to start it yourself later)

The second argument is an optional callback that will be sent to the LiveReload server and called for the listening event. (ie: when the server is ready to start accepting connections)

Watching multiple paths:

Passing an array of paths or glob patterns will allow you to watch multiple directories. All directories have the same configuration options.

server.watch([__dirname + "/js", __dirname + "/css"]);

Command line:

$ livereload "path1, path2, path3"

Using the originalPath option

You can map local CSS files to a remote URL. If your HTML file specifies live CSS files at example.com like this:

<!-- html -->
<head>
  <link rel="stylesheet" href="http://domain.com/css/style.css">
</head>

Then you can tell livereload to substitute a local CSS file instead:

// server.js
var server = livereload.createServer({
    originalPath: "http://domain.com"
});
server.watch('/User/Workspace/test');

Then run the server:

$ node server.js

When /User/Workspace/test/css/style.css is modified, the stylesheet will be reloaded on the page.

Developing livereload

This library is implemented in CoffeeScript 1.x. It may eventually be converted to JavaScript, but because there are many projects that depend on this library, the conversion isn't a priority.

To build the distributable versions, run npm run build.

Run npm test to run the test suite.

Contributing

Contributions welcome, but remember that this library is meant to be small and serve its intended purpose only. Before submitting a pull request, open a new issue to discuss your feature or bug. Please check all open and closed issues.

When submitting code, please keep commits small, and do not modify the README file. Commit both the Coffee and JS files.

Changelog

  • Deprecating the cake tasks for building the project.

0.9.0

  • Serve Livereload client library from an NPM dependency instead of copying the code into the project - smhg
  • Update Chokidar to 3.3.0 which improves performance and reduces CPU load.

0.8.2

  • Fix regression in 0.8.1 where broadcasting failed due to incompatibility between arrays and sets
  • Add debug message when broadcasting to each socket
  • Add debug message for the input message from clients

  • Updates bundled Livereload.js file to v2.3.0 to fix console error.
  • BREAKING CHANGE: The exts and e options now replace the default extensions.
  • Adds the extraExts and ee options to preserve the old behavior of adding extensions to watch.
