express

问题 I'm trying to create a NodeJS app. Below is code that is supposed to be called when an admin creates a new product. Most of the code works, but I'm having trouble rendering the view only after the rest of the code has executed (the DB functions are asynchronous). I've wrapped much of the code in promises (to make certain blocks execute in the right order) and console logs (to pinpoint problems). I'd like to point out that the console.dir(rejProducts) just below console.log(111) logs and empty

问题 I have problem with stacking socket event handler when hitting express route. I need to reconnect in route then sending emit to specific room. At first I connect (socket.io) at page X, then connection is lost cause I move to page Y (with use of router.post) and then in router when I reconnect I add new global socket.io handler for the connection event... and cause of that emits are send multiple times. Ideally, I should use some kind of session to know that user disconnect/connect and be able

问题 I'm using expressJS, and I'm a bit confused about sessions. I have 1 single expressJS server, which is reachable from different URLs. Depending on where the connection is coming frmo (which URL is opened), a different database is used to provide the responses. And I can see that the sessions are conflicting. My assumption is that I should be setting different cookie names, based on the URL of the request, but it seems I can't specify a function within the session config. Any ideas? var app =

问题 I'm creating a project and using nodejs, express for the backend. Everything works fine but as I make any change in the file, nodemon is unable to restart the server due to following error: Error: listen EADDRINUSE: address already in use :::5000 index.js: const express = require("express"); const morgan = require("morgan"); const mongoose = require("mongoose"); const cookieParser = require("cookie-parser"); const session = require("express-session"); const FileStore = require("session-file

问题 I've tried everything but I'm a bit lost on where I should look into this issue. What happens is that once you build the react app and deploy it (using node/express), it works perfectly. However, if you build again and take the build folder to the node server, it gives me that syntax error. This only happens if your browser already opened the app once. I've done research and people were saying that the browser is trying to load the older static files and that's why this occurs. None of their

问题 I'm using Node.js and Express.js and I tried to pass an array of objects from route to other route. I tried to pass through QueryString, but the typeof says that it is an object and it doesn't work properly. I should either pass it to /contacts in another way somehow, or convert the result of the QueryString to an array of object and use it. Here is what I tried to do: app.get('/names', function(req, res) { var arr = new Array(); arr.push({name: 'John'}); arr.push({name: 'Dani'}); res
