javascript - 有没有一种巧妙的方法来组织 Node.js Alexa 代码

Question

有没有一种巧妙的方法来组织 Node.js Alexa 代码。随着我在交互模型中的意图增加，lambda 的 index.js 中的代码行数增加到无法管理的程度。是否有一个如何构建 Alexa Node.js 代码的示例。

Answer 1

我通常将所有状态处理程序放入它们自己的文件中，然后将它们导出。我还将常用的数据/配置放入“资源文件”并导出。

资源.js

const ACCESS_TOKEN = 'sometoken';
const GAME_STATES = {
    TRIVIA: "_TRIVIAMODE", // Asking trivia questions.
    START: "_STARTMODE", // Entry point, start the game.
    HELP: "_HELPMODE", // The user is asking for help.
   };
const APP_ID = 'appid';
const HOST = 'http://localhost:8000';
const API_ROUTES = {
    QUIZZES: HOST + '/api/quizzes/', //all quizzes
    CATEGORIES: HOST + '/api/categories/' //all categories
};
const API_OPTIONS = {
    url: '',
    headers: {
        'Accept': 'application/json',
        "Authorization" : "Bearer " + ACCESS_TOKEN
    }
};

module.exports = {
    ACCESS_TOKEN: ACCESS_TOKEN,
    GAME_STATES: GAME_STATES,
    APP_ID: APP_ID,
    API_OPTIONS: API_OPTIONS,
    API_ROUTES: API_ROUTES
};

我的 index.js 只需要这些文件，并且是应用程序的简单入口点。

index.js

'use strict';

const Alexa = require('alexa-sdk');
const helpers = require('./helpers');
const resources = require('./resources');
const newsessionhandlers = require('./newsessionhandlers');
const helpstatehandlers = require('./helpstatehandlers');
const triviastatehandlers = require('./triviastatehandlers');
const startstatehandlers = require('./startstatehandlers');

const APP_ID = resources.APP_ID;

exports.handler = function (event, context) {
    const alexa = Alexa.handler(event, context);
    alexa.appId = APP_ID;
    alexa.resources = resources.languageString;
    alexa.registerHandlers(newsessionhandlers.newSessionHandlers, startstatehandlers.startStateHandlers, triviastatehandlers.triviaStateHandlers, helpstatehandlers.helpStateHandlers);
    alexa.execute();
};
