QUESTION
I have an ASP.NET Core application that runs an IHostedService
class as an background worker. Now I have two Tasks which run endlessly.
- Task1: Has an WebSocket connection that continuously receives data and stores it in the MSSQL database using EF Core
- Task2: Runs an endless loop which every 10 seconds runs over the Transactions that have been added to the database in Task1
Now my question is:
How do I let these two Tasks run simultaneously? Because right now Task1 is blocking Task2 from executing. Any help or suggestions on how to better solve this problem would be greatly appreciated.

QUESTION
I am looking for the best WS solution for IoT project. I am currently testing my options with Web Sockets. I have tried so far two NPM libraries 'ws' and 'websockets'. They worked great both NodeJS and ReactJS implementation was simple. I am now trying websocket.io. Reading the documentation I struggle to create even a simple working example copying the code directly from the documentation. Since the test code is so simple, I am really confused especially after the positive experience with two previous packages. I am pretty sure I am doing something wrong but I am unable to spot my mistake. I am really thankful for anyone helping to spot what am I not doing right.

QUESTION
I have wrote a simple test using Mocha and Chai. The test is returning as failed
. After changing to my correct test directory and running npm test
the error returned is the below. Please can someone help me figure out why 9000 is already in use?
ANSWER
Answered 2020-Jan-04 at 12:47The reason for the Error: listen EADDRINUSE: address already in use :::9000
error is because of you run npm start
in one terminal and after that npm test
in another terminal. So npm start
starts one server and the require("../hangman-server.js");
in your test tries to start another server on the same port and that results in this error message.
About the 404
, you request /get
but your server will only respond for /
because app.get("/",
will register the middleware for an exact match of /
