nodejs-mongodb | modifying for current version Node.js | Runtime Evironment library

I recently started working on a project with Express and since I'm using Node.js as backend I chose MongoDB as my database. It's my first time working with Mongo but I can't authenticate with Express, it works fine from terminal. I followed the guide from MogoDB blog here. I tried using their Atlas service where I had no problem authenticating. I'm using MongoDB driver. Here's how my connection URI looks like:

I had a problem with running react-native app [Network Error] and the same is discussed here.

ngrok works for a temporary.

At the end of the day when I close my ngrok the token(link) generated is of no use. The next day if I have to run my project I have to regenerate a new token(link) and make the changes everywhere. Also, it's like running 3 ports for a single project.

Is there any solution for the same.

Thank You!!

I am currently working on a project in which I am using a js library called 'jsPsych' to conduct an experiment. I am using node.js, in combination with heroku to host and deploy my app online, with Mongo Atlas as my database. While writing the node.js script for connecting to Mongodb, I used the tutorial provided here https://www.mongodb.com/blog/post/quick-start-nodejs-mongodb--how-to-get-connected-to-your-database. Now everything works fine in a local environment, but as soon as i deploy my experiment online, I get the message: "The experiment failed to load." Upon checking the heroku logs, I saw this:"(node:4) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch()."

This is the node.js script for connecting to mongodb:

I built a Node app using this tutorial. Then I built a Node API using this tutorial. The app uses the app on port 4000 to connect to the API which then connects to a mongodb to store the info on the server.

This setup works great on my local machine, but I'm trying to deploy it on a digital ocean droplet. I have Nginx setup to listen to port 8080 for the main app. I'm able to navigate to the app. But when I try to register a user and submit the data to the API I get the following error in my browser OPTIONS http://localhost:4000/users/register net::ERR_CONNECTION_REFUSED.

I suspect I have to specify something in the Nginx config files. Or would it be a ufw issue? Any help would be much appreciated.

I have an ubuntu droplet on digital ocean and I'm tyring to deploy a nodejs/express api. I used this tutorial to make the api and it runs great on my local machine (MacOS). However, when I try to start the server on my droplet I get this error:

I am using atom for Nodejs-MongoDB development,

to start MongoDB server I need to start cmd as Run as administrator, then only server starts.

but when I use atoms default terminal embedded in IDE, it is opened as user and can't be run as admin, unlike we do in linux using su or sudo,

when I tried net start MongoDB command in atoms-terminal it said permission denied. then how can I run it as admin through atoms terminal?

Good afternoon,

I'm trying to use minikube in order to deploy a multi-page nodejs-mongoDB web app. I have created my app, I have dockerized it and now I'm trying to deploy it locally using minikube. When I execute minikube minikube service my-app --url in a Unix shell I obtain an IP. Putting the IP in the browser I obtain the index page but trying to use the button to switch to another page the browser doesn't switch. I am sure the app is correct because executing it locally I obtain what I want but I cannot understand why this fails in minikube. I am new and I am not an expert. Can anyone help me?

Here the HTML code for the index page :

I have searched many articles and posts asked in different sites, but I didn't find any proper answer. I'm using ejs in my project to render book details in my page.

My project structure looks like:

• asset > ...

• server > server.js

• views > main > bookShow.ejs

I've used the ejs library as the following piece of code in server.js:

I am using a angular login example found online that we use npm start to run. My problem is when i generate a component and add it to the app.modules.js file, the app doesn't display anything just a white page with a loading... on the top left. can this be because i am using npm? when i posted it on stackblitz and added the sidebar component it worked but locally if i add a componenet by ng generate component test and as soon as i add it to the app.modules.js file it shows the white screen but once removed it works perfectly fine. the stackbliz and origional github link is provided below
