Wampy.js is javascript library, that runs both in browser and node.js enviroments, and even in react native enviroment. It implements WAMP v2 specification on top of WebSocket object, also provides additional features like autoreconnecting and use of Chaining Pattern. It has no external dependencies (by default) and is easy to use.
Wampy.js supports next WAMP roles and features:
- Challenge Response Authentication (wampcra method)
- publisher:
- subscriber blackwhite listing
- publisher exclusion
- publisher identification
- subscriber:
- pattern-based subscription
- publication trust levels
- caller:
- caller identification
- progressive call results
- call canceling
- call timeout
- callee:
- caller identification
- call trust levels
- pattern-based registration
- shared registration
Wampy default serializer is JSON, but it also supports msgpack as serializer. In that case you need to include msgpack5.js as dependency. See msgpack5 for more info.
For WAMP v1 implementation, please see tag v0.1.0.
const ws = new Wampy('/ws/', { realm: 'AppRealm' });
ws.subscribe('system.monitor.update', function (dataArr, dataObj) { console.log('Received system.monitor.update event!'); })
.subscribe('client.message', function (dataArr, dataObj) { console.log('Received client.message event!'); })
ws.call('get.server.time', null, {
onSuccess: function (dataArr, dataObj) {
console.log('RPC successfully called');
console.log('Server time is ' + dataArr[0]);
},
onError: function (err, detailsObj) {
console.log('RPC call failed with error ' + err);
}
});
// Somewhere else for example
ws.publish('system.monitor.update');
ws.publish('client.message', 'Hi guys!');Wampy.js can be installed using npm or just by file-copy :)
> npm install wampyFor simple browser usage just download latest browser.zip archive and add wampy-all.min.js file to your page. It contains msgpack encoder plus wampy itself.
<script src="browser/wampy-all.min.js"></script>In case, you don't plan to use msgpack, just include clean wampy.min.js.
<script src="browser/wampy.min.js"></script>In case you are using any kind of build tools and bundlers, like grunt/gulp/webpack/rollup/etc, your entry point can be src/wampy.js if you transpile you code somehow, or dist/wampy.js (default package entry point) which is already transpiled to "env" preset, so it is working out of the box, just bundle modules.
Please refer to Migrating.md for instructions on upgrading major versions.
Below is a description of exposed public API. Btw, wampy has a type definitions, available at DefinitelyTyped.org.
Wampy constructor can take 2 parameters:
- url to wamp server - optional. URL can be specified in next forms:
- Undefined/null. In browser environment page-scheme://page-server:page-port/ws will be used in this case.
- String, begins with '/', meaning some path on current scheme://host:port.
- Full qualified URL, starting with scheme 'ws' or 'wss'.
- Host/domain with possible path, but without scheme. In browser environment page-scheme will be used.
- options hash-table. The only required field is
realm. For node.js environment also necessary to specifyws- websocket module. See description below.
// in browser
ws = new Wampy();
ws = new Wampy('/my-socket-path');
ws = new Wampy('ws://socket.server.com:5000/ws', { autoReconnect: false });
ws = new Wampy({ reconnectInterval: 1*1000 });
// in node.js
w3cws = require('websocket').w3cwebsocket;
ws = new Wampy(null, { ws: w3cws });
ws = new Wampy('/my-socket-path', { ws: w3cws });
ws = new Wampy('ws://socket.server.com:5000/ws', { autoReconnect: false, ws: w3cws });
ws = new Wampy({ reconnectInterval: 1*1000, ws: w3cws });Json serializer will be used by default. If you want to use msgpack serializer, pass it through options. Also, you can use your own serializer. Just be sure, it is supported on WAMP router side!
// in browser
ws = new Wampy('ws://socket.server.com:5000/ws', {
serializer: new MsgpackSerializer(msgpack5)
});
ws = new Wampy({
serializer: new MsgpackSerializer(msgpack5)
});
// in node.js
import {Wampy} from 'wampy';
import {MsgpackSerializer} from 'wampy/dist/serializers';
import {w3cws} from 'websocket';
const msgpack5 = require('msgpack5');
ws = new Wampy('ws://socket.server.com:5000/ws', {
ws: w3cws,
serializer: new MsgpackSerializer(msgpack5())
});
ws = new Wampy({
ws: w3cws,
serializer: new MsgpackSerializer(msgpack5())
});.options() method can be called in two forms:
- without parameters it will return current options
- with one parameter as hash-table it will set new options. Support chaining.
Options attributes description:
- autoReconnect. Default value: true. Enable autoreconnecting. In case of connection failure, Wampy will try to reconnect to WAMP server, and if you were subscribed to any topics, or had registered some procedures, Wampy will resubscribe to that topics and reregister procedures.
- reconnectInterval. Default value: 2000 (ms). Reconnection Interval in ms.
- maxRetries. Default value: 25. Max reconnection attempts. After reaching this value .disconnect() will be called
- realm. Default value: null. WAMP Realm to join on server. See WAMP spec for additional info.
- helloCustomDetails. Default value: null. Custom attributes to send to router on hello.
- authid. Default value: null. Authentication (user) id to use in challenge.
- authmethods. Default value: []. Array of strings of supported authentication methods.
- onChallenge. Default value: null. Callback function. Is fired when wamp server requests authentication during session establishment. This function receives two arguments: auth method and challenge details. Function should return computed signature, based on challenge details. See Challenge Response Authentication section and WAMP Spec CRA for more info.
- onConnect. Default value: null. Callback function. Fired when connection to wamp server is established.
- onClose. Default value: null. Callback function. Fired on closing connection to wamp server.
- onError. Default value: null. Callback function. Fired on error in websocket communication.
- onReconnect. Default value: null. Callback function. Fired every time on reconnection attempt.
- onReconnectSuccess. Default value: null. Callback function. Fired every time when reconnection succeeded.
- ws. Default value: null. User provided WebSocket class. Useful in node enviroment.
- serializer. Default value: JsonSerializer. User provided serializer class. Useful if you plan to use msgpack encoder instead of default json. In practice, msgpack5 tested and works well with Wiola, msgpack-lite doesn't work as expected. Feel free to research other variants.
ws.options();
ws.options({
reconnectInterval: 1000,
maxRetries: 999,
onConnect: function () { console.log('Yahoo! We are online!'); },
onClose: function () { console.log('See you next time!'); },
onError: function () { console.log('Breakdown happened'); },
onReconnect: function () { console.log('Reconnecting...'); },
onReconnectSuccess: function () { console.log('Reconnection succeeded...'); }
});Returns the status of last operation. Wampy is developed in a such way, that every operation returns this even in case of error to suport chaining. But if you want to know status of last operation, you can call .getOpStatus(). This method returns an object with 2 or 3 attributes: code and description and possible request ID. Code is integer, and value > 0 means error. Description is a description of code. Request ID is integer and may be useful in some cases (call canceling for example).
ws.publish('system.monitor.update');
ws.getOpStatus();
// may return { code: 1, description: "Topic URI doesn't meet requirements!" }
// or { code: 2, description: "Server doesn't provide broker role!" }
// or { code: 0, description: "Success!", reqId: 1565723572 }Returns the WAMP Session ID.
ws.getSessionId();Connects to wamp server. url parameter is the same as specified in Constructor. Supports chaining.
ws.connect();
ws.connect('/my-socket-path');
ws.connect('wss://socket.server.com:5000/ws');Disconnects from wamp server. Clears all queues, subscription, calls. Supports chaining.
ws.disconnect();Aborts WAMP session and closes a websocket connection. Supports chaining. If it is called on handshake stage - it sends a abort message to wamp server (as described in spec). Also clears all queues, subscription, calls. Supports chaining.
ws.abort();Wampy.js supports challenge response authentication. To use it you need to provide authid and onChallenge callback as wampy instance options. Also Wampy.js supports "wampcra" authentication method with a little helper plugin "wampy-cra". Just add "wampy-cra" package and use provided methods as shown below.

- argsDict: object payload (may be omitted)
- details: some invocation options object. One attribute of interest in options is "receive_progress" (boolean), which indicates, that caller is willing to receive progressive results, if possible. Another one is "trustlevel", which indicates the call trust level, assigned by dealer (of course if it is configured accordingly).
- result_handler: result handler for case when you want to send progressive results. Just call it with one parameter, same as you return from simple invocation. Also do not forget to set options: { progress: true } for intermediate results.
- error_handler: error handler for case when you want to send progressive results and cought some exception or error.
RPC can return no result (undefined), or it must return an object with next attributes:
- argsList: array result or single value, (may be omitted)
- argsDict: object result payload (may be omitted)
- options: some result options object. Possible attribute of options is "progress": true, which indicates, that it's a progressive result, so there will be more results in future. Be sure to unset "progress" on last result message.
const sqrt_f = function (data) { return { argsList: data.argsList[0]*data.argsList[0] } };
ws.register('sqrt.value', sqrt_f);
ws.register('sqrt.value', {
rpc: sqrt_f,
onSuccess: function (data) {
console.log('RPC successfully registered');
},
onError: function (err) {
console.log('RPC registration failed!', err.error);
}
});Also wampy supports rpc with asynchronous code, such as some user interactions or xhr, using promises. For using this functionality in old browsers you should use polyfills, like es6-promise. Check brower support at can i use site.
const getUserName = function () {
return new Promise(function (resolve, reject) {
/* Ask user to input his username somehow,
and resolve promise with user input at the end */
resolve({ argsList: userInput });
});
};
ws.register('get.user.name', getUserName);Also it is possible to abort rpc processing and throw error with custom application specific data. This data will be passed to caller onError callback.
Exception object with custom data may have next attributes:
- error. String with custom error uri. Must meet a WAMP Spec URI requirements.
- details. Custom details dictionary object. The details object is used for the future extensibility, and used by the WAMP router. This object not passed to the client. For details see WAMP specification 6.1
- argsList. Custom arguments array, this will be forwarded to the caller by the WAMP router's dealer role. Most cases this attribute is used to pass the human readable message to the client.
- argsDict. Custom arguments object, this will be forwarded to the caller by the WAMP router's dealer role.
For more details see WAMP specification 9.2.5.
Note: Any other type of errors (like built in Javascript runtime TypeErrors, ReferenceErrors) and exceptions are catched by wampy and sent back to the client's side, not just this type of custom errors. In this case the details of the error can be lost.
const getSystemInfo = function () {
// Application logic
// for example, you need to get data from db
// and at this time you can't connect to db
// you can throw exception with some details for client application
const UserException = function () {
this.error = 'app.error.no_database_connection';
this.details = {
errorCode: 'ECONNREFUSED'
errorMessage: 'Connection refused by a remote host.',
database: 'db',
host: '1.2.3.4',
port: 5432,
dbtype: 'postgres'
};
this.argsList = ['Not able to connect to the database.'];
this.argsDict = {};
};
throw new UserException();
};
ws.register('get.system.info', getSystemInfo);RPC unregistration from invocations. Supports chaining.
Parameters:
- topicURI. Required. A string that identifies the remote procedure to be unregistered. Must meet a WAMP Spec URI requirements.
- callbacks. Optional. If it is a function - it will be called on successful unregistration
or it can be hash table of callbacks:
- onSuccess: will be called on successful unregistration
- onError: will be called if unregistration would be aborted with one hash-table parameter with following attributes:
- error: string error description
- details: hash-table with some error details
ws.unregister('sqrt.value');
ws.unregister('sqrt.value', {
onSuccess: function (data) {
console.log('RPC successfully unregistered');
},
onError: function (err) {
console.log('RPC unregistration failed!', err.error);
}
});From v5.0 version there is option to provide custom serializer.
Custom serializer instance must meet a few requirements:
- Have a
encode (data)method, that returns encoded data - Have a
decode (data)method, that returns decoded data - Have a
protocolstring property, that contains a protocol name. This name is concatenated with "wamp.2." string and is then passed as websocket subprotocol http header. - Have a
isBinaryboolean property, that indicates, is this a binary protocol or not.
Take a look at JsonSerializer.js or MsgpackSerializer.js as examples.
| Topic | Wampy.js | AutobahnJS |
|---|---|---|
| Runs on | browser | browser and NodeJS |
| Dependencies | msgpack5.js (optional) | when.js, CryptoJS (optional) |
| Creating connection | var connection = new Wampy('ws://127.0.0.1:9000/', { realm: 'realm1' }); | var connection = new autobahn.Connection({url: 'ws://127.0.0.1:9000/', realm: 'realm1'}); |
| Opening a connection | connection opens on creating an instance, or can be opened by: connection.connect() | connection.open(); |
| Connection Callbacks | Wampy supports next callbacks: onConnect, onClose, onError, onReconnect. Callbacks can be specified via options object passed to constructor, or via .options() method. | AutobahnJS provides two callbacks: connection.onopen = function (session) { } and connection.onclose = function (reason/string, details/dict) { } |
| WAMP API methods with parameters | While using Wampy you don't have to explicitly specify the payload type (single value, array, object), just pass it to api method. For example: ws.publish('chat.message.received', 'user message'); ws.publish('chat.message.received', ['user message1', 'user message2']); ws.publish('chat.message.received', { message: 'user message'}); Also Wampy is clever enough to understand some specific options, for example, if you specify a success or error callback to publish method, Wampy will automatically set acknowledge flag to true. |
In AutobahnJS you need to use only arrays and objects, as it's specified in WAMP, and also choose right argument position. For example: session.publish('com.myapp.hello', ['Hello, world!']); session.publish('com.myapp.hello', [], {message: 'Hello, world!'}); Also you need to explicitly provide additional options, like {acknowledge: true} |
| Method callbacks | Most of the API methods take a callbacks parameter, which is hash-table of posible callbacks | AutobahnJS make use of Deffered object, and most of API methods return a deferred object, so you can specify callbacks using .then() method |
| Chaining support | Wampy supports methods chaining. connection.subscribe(...).publish(...).call(...) |
|
| Transport encoders | json, msgpack (optional) | json |
Which one library to use - choice is yours!
Wampy.js uses mocha and chai for tests and istanbul for code coverage. You can run both from cli
# run tests with mocha (use your own favorite reporter)
> mocha -R spec
# or use standart npm test command
> npm test
# for code coverage report run
> npm run-script cover
# and then open coverage/lcov-report/index.html
