futoin-invoker
Advanced tools
Transparently, efficiently and securely invoke remote or local service methods with strict API definition for Node and Browser
Documentation --> FutoIn Guide.
FutoIn Invoker is request initiating part in FutoIn microservice concept. It invokes a FutoIn interface method as described in FTN3: FutoIn Interface Definition. Invoker is not necessary a client - e.g. server may initiate request for callback to client.
Unlike HTTP REST API, FutoIn perfectly fits for "all-in-one" process model with efficient internal calls. Invoker is heavily optimized to reliably process input and output data checks.
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:
Message coding formats:
BinaryData constraintNote: Invoker and Executor are platform/technology-neutral concepts. The implementation is already available in JS and PHP.

Command line:
$ npm install futoin-invoker --save
or
$ yarn add futoin-invoker
Hint: checkout FutoIn CID for all tools setup.
All public classes can be accessed through module:
const AdvancedCCM = require('futoin-invoker').AdvancedCCM;
or included modular way, e.g.:
const AdvancedCCM = require('futoin-invoker/AdvancedCCM');
Pre-built ES5 CJS modules are available under es5/. These modules
can be used with webpack without transpiler - default "browser" entry point
points to ES5 version.
Webpack dists are also available under dist/ folder, but their usage should be limited
to sites without build process.
Warning: check AsyncSteps and AsyncEvent polyfill for older browsers.
The following globals are available:
