fproxy

==========

generic javascript functional lazy proxy abstraction

Functional generic lazy proxy, provides functions to access stored values, arguments, objects, files or documents.

examples

//using local file system text file reader with watcher sync/assync modes
var fProxy=require("fproxy");
var textFile=fProxy(fProxy.mediaDescriptors.file,o=>o.toString());
var text=textFile("test/resources/test.txt");
text(o=>console.log("Text:",o));//get updated & parsed document
//do some external changes to the text file
text(o=>console.log("Text:",o));//get updated & parsed document
console.log(text());//get file content in sync mode (no callback provided)
text((e,o)=>console.log(e||o));//assync mode
//es6 promises using node-swear
var swear=require("node-swear");
var fProxy=require("fproxy");
var textFile=fProxy(fProxy.mediaDescriptors.file,o=>o.toString());
var text=swear(textFile("test/resources/test.txt"));
text().then(o=>log(o)).catch(e=>log(e));

fproxy must be initialized with a media descriptor. The media descriptor has the option to be sync or assync, the resulting access function can be then turned into a promise with node-swear.

A set o media descriptors is available at:

require("fproxy").mediaDescriptors

media descriptors are ES6 classes

mem: Mem, memory storage of single values args: Params, storing passed params obj: Obj, creates new objects where parser is then a constructor file: File, sync/assync file system (use node-swear for ES6 promises)

#media descriptor#

a media descriptor is a class with:

constructor: define parser

load: sync/assync read and parse the data with specific implementation parameters

#inocuous#

  • result document is not polluted with any property of this module.
  • client receives no information/access about other proxy items.
