从app.js传递信息的最佳方法是什么？

Question

在下面的代码中，将信息从app.js传递给choices.js的最佳方法是什么？ 目前，我将它们全部放在一个名为answer的变量中。 这是最好的方法吗？ 谢谢。

这些是app.js中的代码：

var express = require("express");
var cors = require("cors");
var bodyParser = require("body-parser");
var app = express();
var sql = require('msnodesqlv8');
:
var choicesTerm = [];
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(function (req, res, next) {
   console.log(`${req.method} request for '${req.url}' -      
   ${JSON.stringify(req.body)}`);
next();
});

var connStr = "Driver={SQL Server Native Client 11.0};....";
sql.open(connStr, function (err, conn) {        
    var pm = conn.procedureMgr();
    pm.callproc('mySP',sessionID, function (err, results) {
    :
        pm.callproc('mySp2', function (err, results) {
        :            
        if (results.length) 
        {
            var row = results[0];
            var Answers = [];
            Answers = row.Answers.split("|");
            for (var i = 0, len = Answers.length; i < len; i++) {
                var answer = {value: Answers[i], description: Answers[i], question: row.text, detail: row.detail};  //--> pass information to choices.js
                choicesTerm[i] = answer;
            }
         }
      })
   });
 });

 app.use(express.static("./public"));
 app.use(cors());
 app.get("/choices-api", function(req, res) {
    res.json(choicesTerm);
 });

这些是choices.js中的代码：

$(document).ready(function () {
   $.getJSON('/choices-api', printTerms);
 });

function printTerms(terms) {
   var question = terms[0].question;  //--> This is passed from app.js
    var detail = terms[0].detail;   //--> This is passed from app.js
 }
