nv-data-container

• normal json can ONLY carry data at leaf node
• nv-data-container will creat a Object that can carry data on every Node
• its a simplified version of nv-facutil-cfg,easy to use

install

• npm install nv-data-container

usage

 const {data,load,load_to_sdfs} = require("nv-data-container")

 var rt = data("RRRR")
 rt.a = data('AAAA')
 rt.a.x = data('XXXXXXXX')
 rt.b = data('BBBB')
 rt.c = data('CCCC')
 rt.d = data('DDDD')
 rt.d.e = data('EEEE')
 rt.d.e.f = data('FFFF')
