问题 Situation I'm developing a web application that uses Hapi server for REST calls and multi-page Angular2 website client-side. Hapi serves all Angular2 files to the client with: let serverDirPath = path.resolve(__dirname); server.route({ method: "GET", path: "/{param*}", config: { auth: false, handler: { directory: { path: path.join(serverDirPath, "../client"), index: true } } } }); Calling the server root successfully returns "index.html", and after that the Angular2 website works perfectly!

问题 How can I avoid showing both the foreignKey that sequelize creates and the eagerly fetched object through includes? I have the following model structure: FormEntry: owner: User createdBy: User modifiedBy: User formEntryData: [FormEntryData] I modeled it after reading through SequelizeJS docs and came up with the following: const User = sequelize.define('user', { id: { type: Sequelize.BIGINT(20), field: 'user_id', primaryKey: true }, emailAddress: { type: Sequelize.STRING(256), field: 'email

问题 I am developing Chatbot using Azure functions. I want to load the some of the conversations for Chatbot from a file. I am looking for a way to load these conversation data before the function app starts with some function callback.

But this question is asked for C# and I wanted a way to do the same thing in NodeJS 回答1: You can use

问题 I'm trying to run a simple Azure Function that would enter page and generate a PDF depending on what is visible in a browser. I created a NodeJS 12 Azure Function with Linux Consumption Plan (B1). I set PLAYWRIGHT_BROWSERS_PATH to 0 . Function code looks like this: const { chromium } = require("playwright-chromium"); const baseUrl = "http://someurl"; const targetPage = "/action/"; module.exports = async function (context, req) { const browser = await chromium.launch(); const page = await

问题 I just found Sequelize as a good ORM framework to use in my node + MySQL webapp. But when I was designing my database tables, I got so confused about Sequelize associations. Just think about user and system notification in a webapp as a very simple case: The site has many users The site would send notifications to some or every users, and the same notification just save as one record Users could know any notification he/she received is read or not(by a read date) Then I design 3 tables as
