This is a little server (& client library) to allow concurrent editing of any kind of content. The server runs on NodeJS and the client works in NodeJS or a web browser.

At the moment only plain-text is supported, but JSON and rich text should be supported soon.

Check out some cool demos

Installing and running

npm install share

Run the examples with:

# sharejs-exampleserver

From source

# git clone git://
# cd ShareJS

Run the tests:

# cake test

Build the coffeescript into .js:

# cake build
# cake webclient

Run the example server:

# bin/exampleserver

Running a server

There are two ways to run a sharejs server:

  1. Run from a node.js app:

    var connect = require('connect'),
        sharejs = require('share').server;
    var server = connect(connect.logger());
    var options = {db: {type: 'memory'}}; // See docs for options.
    // Attach the sharejs REST and interfaces to the server
    sharejs.attach(server, options);
    console.log('Server running at');
  2. From the command line:

    # sharejs

    Configuration is pulled from a configuration file that can't be easily edited at the moment. For now, I recommend method #1 above.

  3. If you are just mucking around, run:

    # sharejs-exampleserver

    This will run a simple server on port 8000, and host all the example code there. Run it and check out http://localhost:8000/. The server will just store everything in ram, so don't get too attached to your data.

Putting Share.js on your website

If you want to get a simple editor working in your webpage with sharejs, here's what you need to do:

First, get an ace editor on your page:

<div id="editor"></div>

Your web app will need access to the following JS files:

Add these script tags:

<script src=""></script>
<script src="/"></script>
<script src="/share/share.js"></script>
<script src="/share/share-ace.js"></script>

And add this code:

    var editor = ace.edit("editor");'hello', 'text', {host: 'localhost', port: 8000}, function(doc, error) {

Thats about it :)

The hostname and port are not needed if you're hosting your webpage from the same host & port as sharejs.

Have a look at the examples in the repository for demos. If you want to see this examples running, run # sharejs-exampleserver and browse to http://localhost:8000/ .

Writing a client using node.js

The client API is the same whether you're using the web or nodejs.

Here's an example application which opens a document and inserts some text in it. Every time an op is applied to the document, it'll print out the document's version.

Run this from a couple terminal windows when sharejs is running to see it go.

var client = require('share').client;

// Open the 'hello' document, which should have type 'text':'hello', 'text', {host: 'localhost', port: 8000}, function(doc, error) {
    // Insert some text at the start of the document (position 0):
    doc.submitOp({i:"Hi there!\n", p:0});

    // Get the contents of the document for some reason:

    doc.on('change', function(op) {
        console.log('Version: ' + doc.version);

    // Close the doc if you want your node app to exit cleanly
    // doc.close();

See doc/ for full API documentation, and examples/node* for some more example apps.
