£可爱£侵袭症+ 提交于 2021-01-27 18:39:43
问题 I'm a very beginner so I hope my question is not that stupid. What I want to do is to pass a longitude and a latitude from a client-side javascript into a node.js on a server-side. I'm using a fetch and express.js. Below my html code: <!DOCTYPE html> <html lang="en"> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <meta http-equiv="X-UA-Compatible" content="ie=edge" /> </head> <body> latitude: <span id="latitude"></span>°<br /> longitude: <span id="longitude"><

Javascript: what is a callback?

吃可爱长大的小学妹 提交于 2021-01-27 18:36:19
问题 In this article which I was referred to the following statement is made: Callbacks are a way to make sure certain code doesn’t execute until other code has already finished execution. The article then goes on to illustrate this with an example: function doHomework(subject, callback) { alert(`Starting my ${subject} homework.`); callback(); } doHomework('math', function() { alert('Finished my homework'); After this the articles states: As you’ll see, if you type the above code into your console

Angular - Routing is not working (MEAN)

生来就可爱ヽ(ⅴ<●) 提交于 2021-01-27 17:10:39
问题 I'm working on my first Angular app and I have a problem with routing, because app response with "Cannot GET /(url)" errors. Console logs are empty, so after reading many similar topics I suspect issue with server.js: var express = require('express'); var bodyParser = require('body-parser'); var path = require('path'); var http = require('http'); var app = express(); var api = require('./server/api.js'); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({extended: false})); app.use

Why is req.ip in node/Express returning colon separated IP addresses?

五迷三道 提交于 2021-01-27 14:57:36
问题 I am trying to log the remote client IP. Sounds elementary and Express provides the "ip" property on the request object, as in req.ip, to get this info. Also, there is req.ips to get multiple IP addresses from X-Forwarded-For where proxies are involved. I also tried the npm module request-ip. My question is that they all return client IP addresses as in ::ffff:A.B.C.D where A.B.C.D is indeed the address I am looking for. But, my question is: what are the prefixes there? I can understand req

Understanding AudioBuffer to ArrayBuffer conversion

早过忘川 提交于 2021-01-27 14:42:12
问题 I have an AudioBuffer client-side that I'd like to AJAX to a express server. This link shows how a XMLHttpRequest can send/receive binary data - ArrayBuffer. An ArrayBuffer is different to an AudioBuffer (or so I believe) as I decoded an ArrayBuffer to make the AudioBuffer in the first place. This was done using decodeAudioData() as part of the Web Audio API. So my question is, can I convert an AudioBuffer back to an ArrayBuffer? If this is possible, I'd like to then send the ArrayBuffer to

Client-server communication in Node.js

陌路散爱 提交于 2021-01-27 12:50:54
问题 I've recently been getting in to node.js in order to make an online game (for education). Through reading various tutorials I've come up with the simple code shown below. With the code I have I'm capable of client-server communication, which is mostly all I need in order to make the game. There's only one problem, only the client can initiate conversation whereas the server can only respond. In addition to this, I also need to at any moment in time send the current game state from the server

How can I make my nextjs with Express site work on ssl

你。 提交于 2021-01-27 10:20:00
问题 We have a site running on Next.js and Express. This is on a cPanel server with Aapche and together with nginx serving as reverse proxy. I need to have ssl on the site. But I am quite confuused with how the configurations should be. My server.js : const express = require('express') const next = require('next') const https = require('https'); const fs = require('fs'); //const forceSSL = require('express-force-ssl') var ssl_options = { key: fs.readFileSync('/home/myreactsite.key'), cert: fs
