A few words about MoscowJS, july 2014 Konstantin Burkalev, @KSDaemon
WAMP ≠ Windows, Apache, MySQL, PHP
WAMP = Application level protocol, " implementing 2 patterns: • Publish/Subscribe (PubSub)" • Remote Procedure Calls (RPC)
Basic components and definitions • Resource identifier • Transport • Serializer • Session • Realm - domain, namespace • Peer • Client • Router • Role
Architecture
Resource identifiers Required for: • Subscriptions • Procedures • Errors are URI-based • system.send.file • chat.message • users.admins.message • user.profile.updated
Serialization and data types Supported serializers: • JSON • MsgPack Supported data types: Required: Additional: • integer • string • bool • list (array) • dict any, depends on serializer
Messages and payload • [HELLO, Realm|uri, Details|dict] " • [PUBLISH, Request|id, Options|dict, Topic|uri] • [PUBLISH, Request|id, Options|dict, Topic|uri, Arguments|list] • [PUBLISH, Request|id, Options|dict, Topic|uri, Arguments|list, ArgumentsKw|dict] " • [CALL, Request|id, Options|dict, Procedure|uri] • [CALL, Request|id, Options|dict, Procedure|uri, Arguments|list] • [CALL, Request|id, Options|dict, Procedure|uri, Arguments|list, ArgumentsKw|dict] " • [RESULT, CALL.Request|id, Details|dict] • [RESULT, CALL.Request|id, Details|dict, YIELD.Arguments|list] • [RESULT, CALL.Request|id, Details|dict, YIELD.Arguments|list, YIELD.ArgumentsKw|dict] Payload may be supplied as: • Array | List • Hash-table | Dictionary
Transport • Based on messages • Messages are ordered • Bidirectional message flow • Websocket • Raw TCP • HTTP long-polling (under dev) • Unix sockets

Profiles Set of features within each pattern (PubSub, RPC) • Basic profile • Advanced profile
Advanced profile • Session Management • Authentication • Heartbeat
Advanced profile • Publish / Subscribe • Black/white lists • Publisher identification • Pattern-based subscriptions • Meta events • Subscriber list • Events list
Advanced profile • Remote Procedure Calls • black/white lists • Caller identification • Pattern-based RPC registration • Canceling calls • Progressive calls

Subscribe to topics Publish events
Usage example WAMP as a platform for SOA solutions • Unified service bus • Asynchronous procedures execution • Standardization of interaction interfaces • Minimal overhead • Flexible infrastructure • Isolation and loose coupling of services • Easy to connect new services
Implementations • JavaScript! • Autobahn|JS (browser, node.js) • Wampy.js (browser) • Java! • Autobahn|Android (soon) • .NET! • WampSharp (under dev) • PHP! • Thurway Clients • Python! • Autobahn|Python • C++! • Autobahn|Cpp • Erlang! • Erwa • Objective-C! • MDWamp • Lua (under dev) Routers • Python! • Autobahn|Python • Crossbar.io • Erlang! • Erwa • PHP! • Thurway • Lua! • Wiola
Conclusion • Simple and open protocol • RPC + PubSub out of the box • Unified routing • Transport and serialization for every taste • Minimal overhead • Native use in web applications • Allows you to build distributed applications with loosely coupled components • Many implementations in different languages • Open source & community
Useful links • http://wamp.ws! • Description • Specification • Implementations • https://groups.google.com/group/wampws • http://autobahn.ws • https://github.com/crossbario/crossbar/wiki • Crossbar.io • Client examples in different languages
That’s all folks!" Any questions ?

  • 4. Basic components and definitions • Resource identifier • Transport • Serializer • Session • Realm - domain, namespace • Peer • Client • Router • Role
  • 6. Resource identifiers Required for: • Subscriptions • Procedures • Errors are URI-based • system.send.file • chat.message • users.admins.message • user.profile.updated
  • 7. Serialization and data types Supported serializers: • JSON • MsgPack Supported data types: Required: Additional: • integer • string • bool • list (array) • dict any, depends on serializer
