const {
  expHandlers,
  validators,
  arrObj,
  dateUtil,
  excelUtils,
  expUtil,
  htmlUtil,
  ipInfo,
  jsEncrypt,

console.log("This time:", arrObj.getTimestamp());

Set req.functionCode for validate Right of Api

// 
const { setFunctionFromPath } = require("cng-node-js-utils").expHandlers;
// if (req.isFullPath) then req.functionCode = req.pathName; 
// return req.functionCode = subpath;

Send Gmail by API very easy:

  const { sendGmail } = require("cng-node-js-utils");
  sendGmail((receiver, subject, content, senderGmail, passGmail, fromEmail, host = 'smtp.gmail.com', port = 465, secure = true)
  .then(ok=>console.log(ok))
  .catch(err=>console.log(err))

Use LDAP following:

// define your config to your ldap server
const ldapCfg = {
    ldapServerUrl: 'ldap://<host ip or host name>:389'
    , domainNameEmail: '@<your domain name>'
    , connectTimeout: `<timeout when ldap server not response>`
};
// init your connection
const ldapLogin = new LDAPLogin(ldapCfg.ldapServerUrl, ldapCfg.domainNameEmail, ldapCfg.connectTimeout);
// for verify LDAP
let user = await ldapLogin.login(user.username, passHash);
// if error no user return;

Use Router following:

// in this library,  FROM 0.0.5  for auto web API with req.error and req.finalJson in Router
const { postHandler, Router } = require("cng-node-js-utils");

// user custom class or functions:
const { serverHandler } = require("../../handlers/server")

const functionPaths = {
   // for POST method
    POST: {
        "/test": [
            postHandler.jsonProcess        
            , serverHandler.getUserDevice   
            // ... in the Router, auto include 2 function:
            // , checkErrorBeforeResource     // return res(435, {error}) for req.error
            // , sendFinnalJson               // return res(200, req.finalJson or {})
            // ... so you do not add more function for response if you want
        ],
        //...
    },
    // for GET method:
    GET: {
        "/test": [
            postHandler.getToken              // return reg.token
            , serverHandler.verifyToken       // return req.user or req.error
            , serverHandler.getResource       // web response => return req.finalJson for user api and next()
            // ... in the Router, auto include 2 function:
            // , checkErrorBeforeResource     // return res(435, {error}) for req.error
            // , sendFinnalJson               // return res(200, req.finalJson or {})
            // ... so you do not add more function for response if you want
        ],
        //...
    },
}
// export router of Express the same old version
module.exports = (new Router(functionPaths)).getExpressRouter();
