Import module

const _tool=require('tool-lib');

CEP Import module

const _tool=require('tool-lib/cep');

Use:

• Remove null values from JSON _tool.clearJsonNull(json);

• Determine the incoming data type and return a string _tool.dataType(obj);

• Recursive creation of directories _tool.mkdir(dir)

• CEP version Recursive creation of directories _tool.cep_mkdir(dir)

• Converting Boolean values of strings to Boolean values _tool.strBol(str)

  • const a='true'; console.log(typeof(_tool.strBol(a)));//boolean

• Determine whether the specified position of the array is a number _tool.arrIsNum(data,num)

  • Returns Boolean values

• Returns which array element appears in the string and returns the subscript of the array _tool.arrIsNum(data,num)

  • return JSON

• How many decimal places to take _tool.float(num,n[,option])

  • return num
    • [option]The default is '1'，example：_tool.float(3.25335,2)//3.25
    • If the parameter is'0', then use the following complement'0'；example:_tool.float(3.25,4,0)//3.2500

• Returns the index of the closest value _tool.nearIndex(arr,val)

  • return index
    • example:let arr=[[3.56,4,5,2.25,8]];arr[await _tool.nearIndex(arr,1)]//2.25

• Compare the values in json, and return true if matched _tool.compareJson(json,val)

  • If the match returns true

• Hardware information of this machine _tool.localHardwareInformation const info=_tool.localHardwareInformation

  • info.ipv4 {ip,mac,netmask,cidr}
  • info.ipv6 {ip,mac,netmask,cidr}
