hello world
var jf = require('json.filed');
jf.filed('./data.json')
.write( { msg: 'hello world.'} )
.read( json => { console.log( json.msg ) } )
.exec();
REPL
Supports REPL feature.
$ sudo npm install -g json.filed$ json.filed> hello = jf.filed('./hello.json')filedExecuter { parent: null, io: [Function], read: [Function], in: [Function], write: [Function], out: [Function], copy: [Function], link: [Function], pass: [Function], filter: [Function], calledback: [Function], httpServe: [Function], parallel: [Function], collect: [Function], exec: [Function], plan: [Function], file: [Function], _events: { error: [Function] }, _eventsCount: 1 }> hello.read( o => { val = o }).exec()rootPlan { _nextPlan: executePlan { _nextPlan: notexecPlan { _nextPlan: null, next: [Function], exec: [Function], runtime: [Object] }, next: [Function], exec: [Function], runtime: runtimeInformation { collect: [Function], addJsonFile: [Function], removeJsonFile: [Function], resetJsonFile: [Function], countInProgress: [Function] } }, next: [Function], exec: [Function], fixedFiles: [ JsonFile { path: [Function] } ], runtime: runtimeInformation { collect: [Function], addJsonFile: [Function], removeJsonFile: [Function], resetJsonFile: [Function], countInProgress: [Function] } }> val{ msg: 'Hello World' }
