• slightly faster than nv-facutil-duplex-worker-bw

install

• npm install nv-facutil-duplex-worker-nd

usage

  # in main
  const creat   = require("nv-facutil-duplex-worker-nd").main;

  ReqFunc:  async(data:Any)->Any

  var worker = await creat(worker_script_path:String, handle: async(data:Any, req_func:ReqFunc)=>Any)  
      
      await worker.req(data) 
   

  # in worker
  const creat   = require("nv-facutil-duplex-worker-nd").worker;

      creat(handle: async(data:Any, req_func:ReqFunc)=>Any)
