 1 | # How to contribute to my project
 2 | 
 3 | **tldr;**
 4 | 
 5 | - Email me if I forget about you
 6 | - Write unit tests
 7 | - Make small pull requests
 8 | - If you need to recompile, commit those changes separately
 9 | 
10 | I love pull requests, but I'm sometimes bad at replying to pull requests &
11 | emails. Sorry - its not you, its me. Please email me regularly if replying is
12 | important. (I'm me@josephg.com )
13 | 
14 | I get mad if I have to fix bugs in your code later.
15 | As such, all new features introduced in pull requests MUST include tests
16 | for any added functionality. Unless they fix an active bug, I will not accept a
17 | pull request without tests. If they fix an active bug and writing tests sounds
18 | hard, I might add tests myself.
19 | 
20 | Please break pull requests up into small atomic changes. Small changes are easy
21 | to evaluate and merge. Large changes are much harder.
22 | 
23 | Please separate recompilation commits from actual code changes - recompiling
24 | can generate giant diffs and make pull requests hard to read.

/Changelog.md:
--------------------------------------------------------------------------------
 1 | > This document was only added recently. Its missing a lot of the history.
 2 | 
 3 | # 1.2.0 -> 2.0.0
 4 | 
 5 | The client API has better websocket API support.
 6 | 
 7 | - **IMPORTANT API CHANGE** `client.onmessage` now receives an object with a data
 8 | property, instead of the message raw. This better matches the websocket API.
 9 | - I've added a couple of capability flags to the session object, namely
10 | `canSendWhileConnecting` and `canSendJSON`.
11 | - Fixed a bug where options.prev had no effect.
12 | - The client no longer throws if you send messages after the socket is closed.
13 | It silently drops them instead (for better or worse...)
14 | 
15 | If your code previously looked like this:
16 | 
17 | ```javascript
18 | session.onmessage = function(data) {
19 |   window.alert(data.x, data.y);
20 | };
21 | ```
22 | 
23 | it will now look like this:
24 | 
25 | ```javascript
26 | session.onmessage = function(message) {
27 |   window.alert(message.data.x, message.data.y);
28 | };
29 | ```
30 | 
31 | Despite the major version bump, this release actually has very few changes. I
32 | was considering rewriting all of browserchannel in javascript (I'd still like to
33 | at some point), but I worry that doing so will introduce new bugs in the code
34 | that weren't there before. The version bump is necessary because of the change
35 | to the client API.
36 | 
37 | I almost committed a [closure-javascript version of
38 | BCSocket](https://github.com/josephg/node-browserchannel/blob/javascript-
39 | bcsocket/lib/bcsocket.js) but it has new bugs, its bigger, its harder to read
40 | and even with better closure compiler type annotations it compiles to more code.
41 | I decided the transition isn't worth it at the moment. If/when I make that
42 | change, it won't result in any API changes so I can do it without bumping the
43 | major version.
44 | 
45 | I also almost changed the server API around connections. I may still add a
46 | .stream() method to server sessions, but I haven't for now because node's
47 | Writable streams are unusable by browserchannel. I could expose the old node
48 | streams 1 duplex API, but I decided instead to just keep the API we have now.
49 | (its *fine*).

  1 | # A [BrowserChannel](http://closure-library.googlecode.com/svn/trunk/closure/goog/net/browserchannel.js) server.
  2 | 
  3 | [![Build Status](https://travis-ci.org/josephg/node-browserchannel.svg?branch=master)](https://travis-ci.org/josephg/node-browserchannel)
  4 | 
  5 | **tldr;** Its like socket.io, but it scales better and it has fewer bugs. It
  6 | just does long polling. It also doesn't support websockets and doesn't support
  7 | cross-domain requests out of the box.
  8 | 
  9 | > *Note:* [Websocket support](http://caniuse.com/#feat=websockets) is now reasonably universal. Strongly consider using raw websockets for new projects.
 10 | 
 11 | BrowserChannel is google's version of [socket.io](http://socket.io) from when they first put
 12 | chat in gmail. Unlike socket.io, browserchannel guarantees:
 13 | 
 14 | - Messages will arrive in order
 15 | - Messages will never arrive on the server after a connection has closed
 16 | - The mail will always get through on any browser that google talk works on, which is all of them.
 17 | 
 18 | node-browserchannel:
 19 | 
 20 | - Is compatible with the closure library's browserchannel implementation
 21 | - Is super thoroughly tested
 22 | - Works in IE5.5+, iOS, Safari, Chrome, Firefox, etc.
 23 | - Works in any network environment (incl. behind buffering proxies)
 24 | 
 25 | ---
 26 | 
 27 | # Use it
 28 | 
 29 |     # npm install browserchannel
 30 | 
 31 | Browserchannel is implemented as connect middleware. Here's an echo server:
 32 | 
 33 | ```javascript
 34 | var browserChannel = require('browserchannel').server;
 35 | var connect = require('connect');
 36 | 
 37 | var server = connect(
 38 |   connect.static("#{__dirname}/public"),
 39 |   browserChannel(function(session) {
 40 |     console.log('New session: ' + session.id +
 41 |       ' from ' + session.address +
 42 |       ' with cookies ' + session.headers.cookie);
 43 | 
 44 |     session.on('message', function(data) {
 45 |       console.log(session.id + ' sent ' + JSON.stringify(data));
 46 |       session.send(data);
 47 |     });
 48 | 
 49 |     session.on('close', function(reason) {
 50 |       console.log(session.id + ' disconnected (' + reason + ')');
 51 |     });
 52 |       
 53 |     // This tells the session to disconnect and don't reconnect
 54 |     //session.stop();
 55 |     
 56 |     // This kills the session.
 57 |     //session.close();
 58 |   })
 59 | );
 60 | 
 61 | server.listen(4444);
 62 | 
 63 | console.log('Echo server listening on localhost:4444');
 64 | ```
 65 | 
 66 | The client emulates the [websocket API](http://dev.w3.org/html5/websockets/). Here is a simple client:
 67 | 
 68 | ```javascript
 69 | var BCSocket = require('browserchannel').BCSocket;
 70 | 
 71 | var socket = new BCSocket('http://localhost:4321/channel');
 72 | socket.onopen = function() {
 73 |   socket.send({hi:'there'});
 74 | };
 75 | socket.onmessage = function(message) {
 76 |   console.log('got message', message);
 77 | };
 78 | 
 79 | // later...
 80 | socket.close()
 81 | ```
 82 | 
 83 | ... Or from a website:
 84 | 
 85 | ```html
 86 | <html><head>
 87 | <script src='/channel/bcsocket.js'></script>
 88 | <script>
 89 | socket = new BCSocket('/channel');
 90 | socket.onopen = function() {
 91 |   socket.send({hi:'there'});
 92 |   socket.close();
 93 | };
 94 | socket.onmessage = function(message) {
 95 |   // ...
 96 | };
 97 | </script>
 98 | ```
 99 | 
100 | You can also ask the client to automatically reconnect whenever its been disconnected. - Which is
101 | super useful.
102 | 
103 | ```javascript
104 | var BCSocket = require('browserchannel').BCSocket;
105 | socket = new BCSocket('http://localhost:4321/channel', reconnect:true);
106 | socket.onopen = function() {
107 |   socket.send("I just connected!");
108 | };
109 | ```
110 | 
111 | ---
112 | 
113 | # Differences from Websocket
114 | 
115 | - You can send messages before the client has connected. This is recommended,
116 |   as any messages sent synchronously with the connection's creation will be
117 |   sent during the initial request. This removes an extra round-trip.
118 | - The send method can pass a callback which will be called when the message has
119 |   been received. **NOTE**: If the client closes, it is not guaranteed that this
120 |   method will ever be called.
121 | - Send uses google's JSON encoder. Its almost the same as the browser one, but
122 |   `{x:undefined}` turns in to `{x:null}` not `{}`.
123 | 
124 | # API
125 | 
126 | ## Server API
127 | 
128 | The server is created as connect / express middleware. You create the middleware by calling
129 | 
130 | ```javascript
131 | var browserChannel = require('browserchannel').server;
132 | 
133 | var middleware = browserChannel(options, function(session) {
134 |   ...
135 | });
136 |  
137 | // Express
138 | app.use(middleware);
139 | ```
140 | 
141 | The options object is optional. The following server options are supported:
142 | 
143 | - **hostPrefixes**: Array of extra subdomain prefixes on which clients can
144 | connect. Even modern browsers impose per-domain connection limits, which means
145 | that when you have a few tabs open with browserchannel requests your
146 | connections might stop woroking. Use subdomains to get around this limit.
147 | For example, if you're listening for connections on *example.com*, you can
148 | specify `hostPrefixes: ['a', 'b', 'c']` to make clients send requests to
149 | *a.example.com*, *b.example.com* and *c.example.com*.
150 | - **base**: The base URL on which to listen for connections. (Defaults to
151 | `"/channel"`). Think of the base URL as a URL passed into `app.use(url,
152 | middleware)`.
153 | - **headers**: Map of additional response headers to send with requests.
154 | - **cors**: Set `Access-Control-Allow-Origin` header. This allows you to
155 | specify a domain which is allowed to access the browserchannel server. See
156 | [mozilla documentation](https://developer.mozilla.org/en/http_access_control)
157 | for more information. You can set this to `'*'` to allow your server to be
158 | accessed from clients on any domain, but this may open up security
159 | vulnerabilities in your application as malicious sites could get users to
160 | connect to your server and send arbitrary messages.
161 | - **corsAllowCredentials**: (Default *false*) Sets the
162 | `Access-Control-Allow-Credentials` header in responses. This allows
163 | cross-domain requests to send their cookies. You cannot do this if you set
164 | `cors:'*'`. To make this work you must also add the `{crossDomainXhr:true}`
165 | option in the client. See [mozilla
166 | documentation](https://developer.mozilla.org/en-US/docs/HTTP/Access_control_CORS#Requests_with_credentials)
167 | for more information. Setting this is equivalent to setting
168 | `headers:{'Access-Control-Allow-Credentials':true}`.
169 | - **keepAliveInterval**: (Default *20000 = 20 seconds*). Keepalives
170 | are sent periodically to make sure http connections aren't closed by eager
171 | clients. The standard timeout is 30 seconds, so sending keepalives every 20
172 | seconds keeps the connection healthy. Time is specified in milliseconds
173 | - **sessionTimeoutInterval**: (Default *30 seconds*). Amount of time we wait
174 | before evicting a client connection. Setting this lower will make the server
175 | notice disconnected clients more quickly. Setting it higher will make
176 | connections more resiliant to temporary network disconnection. Time specified
177 | in milliseconds.
178 | 
179 | Note that by default, CORS support is disabled. This follows the lead of
180 | browsers. Be very careful when enabling CORS & CORS credentials. You should
181 | explicitly whitelist sites from which your users will connect.
182 | 
183 | Setting hostPrefixes in production is important - if you don't enable host
184 | prefixes, browserchannel will stop working for a user once they have more than
185 | a couple of tabs open. Set DNS rules to make the extra prefixes all point to
186 | the same server / cluster.
187 | 
188 | ### Client sessions
189 | 
190 | Whenever a client connects, your middleware's method is called with the new
191 | session. The session is a nodejs event emitter with the following properties:
192 | 
193 | - **id**: An ID that is unique to the session.
194 | - **address**: A string containing the IP address of the connecting client.
195 | - **query**: An object containing the parsed HTTP query of the initial
196 | connection. Any custom query parameters will be exposed on this object.
197 | - **state**: The current state of the connection. One of `'init'`, `'ok'` and
198 | `'closed'`. When the state is changed, the client will emit a *state changed*
199 | event with the new state and old state as event parameters.
200 | - **appVersion**: The client's reported application version, or null. You can
201 | use this to reject clients which are connecting from old versions of your
202 | client.
203 | 
204 | #### Sending messages
205 | 
206 | You can **send messages** to the client using `client.send(data, callback)`. The
207 | data parameter will be automatically JSON.stringified. If specified, the
208 | callback will be called once the message has been acknowledged by the client.
209 | 
210 | > Note: If you wrap a browserchannel connection in a nodejs stream, don't use
211 | > the callback. Node streams will only allow one message to be in flight at a
212 | > time. As a result, you'll get much lower message throughput than you
213 | > otherwise should.
214 | 
215 | 
216 | #### Receiving messages
217 | 
218 | Receive messages through the `message` event.
219 | 
220 | ```javascript
221 | session.on('message', function(data) {
222 |   // ...
223 | });
224 | ```
225 | 
226 | The message will be a javascript object if you sent a javascript object using
227 | the client API.
228 | 
229 | #### Stopping and closing connections
230 | 
231 | Browserchannel has two different methods for closing client connections, *session.stop*
232 | and *session.close*. Both methods disconnect the client. The difference is that
233 | stop also tells the client not to reconnect. You should use close when a
234 | recoverable server error occurs, and stop when the client is in an
235 | unrecoverable invalid state.
236 | 
237 | For example, if an exception occurs handling a message from a client, you may
238 | want to call close() to force the client to reconnect. On the other hand, if a
239 | browser is trying to connect using an old version of your app, you should call
240 | stop(). In the browser, you can handle the stop message with a notice to
241 | refresh the browser tab.
242 | 
243 | #### Events
244 | 
245 | The client is an event emitter. It fires the following events:
246 | 
247 | - **close (reason)**: The client connection was closed. This will happen for a variety
248 | of reasons (timeouts, explicit disconnection from the client, disconnection
249 | from the server, etc). Once a client has closed, it is gone forever. If the
250 | client reconnects, it will do so by establishing a new session.
251 | - **message (data)**: The server received a message from the client. The data
252 | object will be a javascript object.
253 | - **state changed (newstate, oldstate)**: The client's state changed. Clients
254 | start in the 'init' state. They move to the 'ok' state when the session is
255 | established then go to the 'closed' state. If a client reconnects, they will
256 | create an entirely new session. init -> ok -> closed are the only three valid
257 | state transitions.
258 | 
259 | 
260 | ## Client API
261 | 
262 | For the most part, the client API is identical to websockets.
263 | 
264 | ```javascript
265 | var socket = new BCSocket(hostname, opts);
266 | ```
267 | 
268 | opts is optional, and if it exists it should be an object which can contain the
269 | following properties:
270 | 
271 | - **appVersion**: Your application's protocol version. This is passed to the server-side
272 |   browserchannel code, in through your session handler as `session.appVersion`
273 | - **prev**: The previous BCSocket object, if one exists. When the socket is established,
274 |   the previous bcsocket session will be disconnected as we reconnect.
275 | - **reconnect**: Tell the socket to automatically reconnect when its been disconnected.
276 | - **failFast**: Make the socket report errors immediately, rather than trying a
277 |   few times first.
278 | - **crossDomainXhr**: Set to true to enable the cross-origin credential
279 |   flags in XHR requests. The server must send the
280 |   Access-Control-Allow-Credentials header and can't use wildcard access
281 |   control hostnames. See:
282 |     http://www.html5rocks.com/en/tutorials/cors/#toc-withcredentials
283 | - **affinity**: Set to null to disable session affinity token passing.
284 | - **affinityParam**: Session affinity tokens are sent in the query string as
285 |   the GET parameter `a` by default. Your application may override the
286 |   variable name if there is a query string conflict.
287 | 
288 | There are a couple of differences from the websocket API:
289 | 
290 | - You can (and are encouraged to) call `send()` using JSON objects instead of
291 | mere strings. JSON serialization is handled by the library, and works in all
292 | browsers.
293 | - You can send messages immediately before the session is established. This
294 | removes a roundtrip before client messages can arrive on the server.
295 | - Browserchannel sessions have reconnect support. You should register
296 | `socket.onconnecting = function() {...}` to send any messages which need to be
297 | sent as the session is established. This will be called both when the socket is
298 | first established *and* when the session reconnects.
299 | 
300 | 
301 | ---
302 | 
303 | # Caveats
304 | 
305 | - It doesn't do RPC.
306 | - Currently there's no websocket support. So, its higher bandwidth on modern
307 | browsers. On iOS you'll sometimes see a perpetual loading spinner in the top
308 | black bar.
309 |

311 | 
312 | # How to rebuild the client
313 | 
314 | The client uses google's [closure library](https://developers.google.com/closure/library/)
315 | & [compiler](https://developers.google.com/closure/compiler/). There's a couple small bugs that google
316 | still hasn't fixed in their library (and probably never will), so I have a patch file kicking around.
317 | 
318 | Rebuilding the client library is annoying, so I keep an up to date compiled copy in `dist/`.
319 | 
320 | 1. Download the closure library as a sibling of this repository
321 | 
322 |     ```
323 |     cd ..
324 |     git clone https://code.google.com/p/closure-library/
325 |     git checkout -q df47692b1bacd494548a3b00b150d9f6a428d58a
326 |     cd closure-library
327 |     ```
328 | 
329 | 2. Download the closure compiler
330 | 
331 |     ```
332 |     curl http://dl.google.com/closure-compiler/compiler-latest.tar.gz > compiler-latest.tar.gz
333 |     tar -xvf compiler-latest.tar.gz
334 |     mv compiler-latest/compiler.jar .
335 |     ```
336 | 
337 | 3. Patch the library
338 | 
339 |     ```
340 |     cd closure/
341 |     patch -p0 < ../../node-browserchannel/closure-*.patch
342 |     ```
343 | 
344 | 4. Build
345 | 
346 |     ```
347 |     cd ../../node-browserchannel
348 |     make
349 |     ```
350 | 
351 | ## Caveats
352 | 
353 | ### Java ~1.7 is a hard requirement.
354 | Building this project with Java ~1.6 will fail, and may even fail silently.
355 | 
356 | ### Known issue with latest closure-library.
357 | Until [the bug][34] introduced in `closure-library#83c6a0b9`
358 | is resolved upstream, use `closure-library#df47692`

/lib/bcsocket.coffee:
--------------------------------------------------------------------------------
  1 | # This is a little wrapper around browserchannels which exposes something thats compatible
  2 | # with the websocket API. It also supports automatic reconnecting, and some other goodies.
  3 | #
  4 | # You can use it just like websockets:
  5 | #
  6 | #     var socket = new BCSocket '/foo'
  7 | #     socket.onopen = ->
  8 | #       socket.send 'hi mum!'
  9 | #     socket.onmessage = (message) ->
 10 | #       console.log 'got message', message
 11 | # 
 12 | # ... etc. See here for specs:
 13 | # http://dev.w3.org/html5/websockets/
 14 | #
 15 | # I've also added:
 16 | #
 17 | # - You can reconnect a disconnected socket using .open().
 18 | # - .send() transparently works with JSON objects.
 19 | # - .sendMap() works as a lower level sending mechanism.
 20 | # - The second argument can be an options argument. Valid options:
 21 | #   - **appVersion**: Your application's protocol version. This is passed to the server-side
 22 | #     browserchannel code, in through your session handler as `session.appVersion`
 23 | #   - **prev**: The previous BCSocket object, if one exists. When the socket is established,
 24 | #     the previous bcsocket session will be disconnected as we reconnect.
 25 | #   - **reconnect**: Tell the socket to automatically reconnect when its been disconnected.
 26 | #   - **failFast**: Make the socket report errors immediately, rather than trying a few times
 27 | #     first.
 28 | #   - **crossDomainXhr**: Set to true to enable the cross-origin credential
 29 | #     flags in XHR requests. The server must send the
 30 | #     Access-Control-Allow-Credentials header and can't use wildcard access
 31 | #     control hostnames. This is needed if you're using host prefixes. See:
 32 | #       http://www.html5rocks.com/en/tutorials/cors/#toc-withcredentials
 33 | #   - **extraParams**: Extra query parameters to be sent with requests. If
 34 | #     present, this should be a map of query parameter / value pairs. Note that
 35 | #     these parameters are resent with every request, so you might want to think
 36 | #     twice before putting a lot of stuff in here.
 37 | #   - **extraHeaders**: Extra headers to add to requests. Be advised that not
 38 | #     all headers are allowed by the XHR spec. Headers from NodeJS clients are
 39 | #     unrestricted.

--------------------------------------------------------------------------------
  1 | # # Tests for the bare BrowserChannel client.
  2 | #
  3 | # Run them by first launching
  4 | #
  5 | #     % coffee test/support/runserver.coffee
  6 | #
  7 | # ... Then browsing to localhost:4321 in your browser or running:
  8 | #
  9 | #     % mocha test/bcsocket.coffee
 10 | #
 11 | # from the command line. You should do both kinds of testing before pushing.
 12 | #
 13 | #
 14 | # These tests are pretty simple and primitive. The reality is, google's browserchannel
 15 | # client library is pretty bloody well tested. (I'm not interested in rewriting that test suite)
 16 | #
 17 | # However, its important to do some sanity checks on the exported browserchannel bits to
 18 | # make sure closure isn't doing anything wacky. Also this acts as a nice little integration
 19 | # test for the server, _and_ its useful to make sure that all the browsers node-browserchannel
 20 | # supports are behaving themselves.
 21 | #
 22 | # Oh yeah, and these tests will be run on the nodejs version of browserchannel, which has
 23 | # a lot of silly little parts.
 24 | #
 25 | # These tests will also be useful if the browserchannel protocol ever changes.
 26 | #
 27 | # Interestingly, most of the benefits of this test suite come from a single test (really, any
 28 | # test). If any test passes, they'll all probably pass.
 29 | #
 30 | #
 31 | # ## Known Issues
 32 | #
 33 | # There's three weird issues with this test suite:
 34 | #
 35 | # - Sometimes (maybe, 1 in 10) times the test is run from nodejs, it dies in a weird inconsistant
 36 | #   state.
 37 | # - After a test run, 4 sessions are allowed to time out by the server. (Its odd because I'm calling
 38 | #   disconnect() in tearDown).
