问题 I am using promises to avoid the nesting structure created by callbacks. However in this code I still have some nesting. Is there something I am doing wrong or is this un-avoidable in this case? In this case I want to check and see if a profile exists and if it does not I want to create it. DB.getProfile(id_google).then((resGet) => { if(!resGet[0]){ console.log('PROFILE - NOT FOUND - MUST CREATE'); DB.createProfile(id_google, email, name, pic_url).then((resCreate)=>{ console.log('PROFILE

问题 I have a node+express website running on my ubuntu server on port 10000 with nginx on port 80 using a proxy_pass to localhost:10000. My issue is that when I ask for the host in express it returns localhost instead of my domain name. I use the nginx proxy so I can manage several domains on the machine pointing to different applications. Is there a way to keep the original host name on my node+express server while still using proxy_pass in nginx? 回答1: By default, nginx sets the Host header in

问题 I'm struggling with serving a build created with "create-react-app" using Express with Helmet. I'm getting several errors in the explorer console related to Content Security Policy: csp-errors Of course, it isn't showing the app. I noticed that if a remove Helmet as middleware in Express it works but that's not the solution I want. This is my server code: const express = require('express'); const helmet = require('helmet'); const cors = require('cors'); const morgan = require('morgan'); const

问题 I have come across two different ways to define express, use() middleware and am wondering if there is any difference between them or if it is simply syntax sugar? A const app = express(); app.use(cors()); app.use(responseTime()); app.use(someFunction); app.use(anotherHandler); app.use(failureHandler); B const app = express(); app.use(cors()) .use(responseTime()) .use(someFunction) .use(anotherHandler) .use(failureHandler); 回答1: They are not two ways of using it. They are the same way. By

问题 I currently have an SPA built with MERN and I want to improve it further by adding a scheduled update to a particular collection in my MongoDB database by setting a boolean field in all of the documents in a collection to false every midnight. Can someone point me to the right direction on how to accomplish this? I want to be able to scale it as well at some point - for example, have a value saved in a document in another collection to indicate the time where these boolean fields will be

问题 I'm making a simple web application using API's and express. But I am getting different output than expected. My output contains text including HTML tags.

问题 Fellows I develop a Rest API and I want when a route does not exist to send a custom message instead of an html one that express.js sends by default. As fas as I searched I could not find a way to do that. I tried to do: app.all("*",function(req,res){ res.status(404) res.header("Content Type","application/json") res.end(JSON.stringify({message:"Route not found"})) }); But it matches and all already implemented methods. I want only the unmached one to get handled by my app. Edit 1 For each
