FutoIn Invoker - Reference Implementation. Transparently and efficiently invoke remote or local service methods with strict API definition for Node and Browser
Reference implementation of:
FTN7: FutoIn Invoker Concept
Version: 1.5
FTN3: FutoIn Interface Definition
Version: 1.3
FTN5: FutoIn HTTP integration
Version: 1.2
FTN9: FutoIn Interface - AuditLog
Version: 1.0 (client)
FTN14: FutoIn Cache
Version: 1.0 (client)
FutoIn Invoker is a peer which initiates a request - invokes a FutoIn interface method as described in FTN3: FutoIn Interface Definition. It is not necessary a client - e.g. server may initiate request for event delivery to client.
The method can be implemented locally or remotely - it is transparent to invoking code. A similar concept can be found in CORBA and other more heavy request brokers.
Strict FutoIn interface (iface) definition and transport protocol is defined in FTN3 spec mentioned above. As it is based on JSON, both client and server can be implemented in a few minutes almost in any technology. However, Invoker and Executor concept provide significant benefits for efficiency, reliability and error control.
The core of invoker is CCM - Connection and Credentials Manager. It has the following advantages:
The primary communication channel is WebSockets. Large raw data upload and download is also supported through automatic fallback to HTTP(S).
SimpleCCM - a light version without heavy processing of iface definition (ideal for browser) AdvancedCCM - full featured CCM (extends SimpleCCM)
Communication methods:
Note: Invoker and Executor are platform/technology-neutral concepts. The implementation is already available in JS and PHP. Hopefully, others are upcoming
Command line:
$ npm install futoin-invoker --save
All public classes can be accessed through module:
var AdvancedCCM = require('futoin-invoker').AdvancedCCM;
or included modular way, e.g.:
var AdvancedCCM = require('futoin-invoker/AdvancedCCM');
$ bower install futoin-invoker --save
Please note that browser build is available under in dist/ folder in sources generated with pure-sjc. It includes modular parts of lodash.
Note: there are the following globals available:
NOTE: more complex examples should be found in futoin-executor
