Is there any way to create and initiate a MongoDB server and a DB inside Node.JS and use Mongoose with that MongoDB server? I want to rent a VPS and use it with Node.JS, but I don't know how to run a Node.JS and MongoDB server at the same time in a VPS. I only have used MongoDB and Node.JS in my mac.
PD: Sorry for my English.
Maybe you're confusing between mongoDB database and Node.js application.
You don't run a mongoDB IN Node.js, they are two different things and processes.
First of all you must have a mongoDB instance running on the machine.
Here's only one example to run it as a service on a Linux server.
Node.js is a server side environment that among other things can CONNECT to a mongoDB instance to store o retrieve data. You have to install it as well on your server.
Mongoose is a Node.js module that "mediates" the connection from a Node.js application to MongoDB and give you a set of utility to interact with your mongo database.

I have 2 database servers. One for dev and one for production, what I want to do is to create a dumb of production DB and sync it with dev DB at a specific time using nodejs.
Postgres provides pg_dump (single DB) and pg_dumpall (all DBs) utilities out of the box. The simplest way would probably be a cron job to automate the backup of your source DB and scp it over to a destination server, then restore the DB on the destination server by a cron job:
On the source server:
crontab -e
0 0 * * 0 pg_dumpall -U postgres > ~/backups/backup.bak
# scp to your destination server
If you’re working in one of the major cloud environments they will have their own tools that can help, eg AWS you can automate snapshots, then restore from a snapshot (or have a lambda perform the restore from the snapshot as you suggest in nodeJs)
Or (super-cool way) is to use AWS DMS (Data Migration Services) CDC - Change Data Capture and you can replicate a source DB instantaneously with one or many target replicas (avoiding the need for dumps and restores)
I asume you meant dump, and googled that for you:

Now you just should make sure it runs as a cronjob.
I use zeit-now to deploy my website.
But I can't connect to my MySQL server.
I'm sure my MySQL server is able to be connected on my machine.
Here is my repo.
Any solution?
In the FAQ it says
Now itself focuses on being the best platform for serverless hosting. This means that the workloads we handle are static or stateless.
Still, you're trying to connect to your database on localhost. Although running a database instance in a docker container might be an option for a staging system, it definitely is not for production systems, since you will lose the data when you restart/redeploy. And you don't seem to startup a docker container in your deployment.
You should use a cloud database provider instead:
Use Cloud Databases that offer secure (preferably HTTPS-based) gateways, for example: Azure CosmosDB, MongoDB, Atlas, Firebase, Google Cloud SQL
I have installed MongoDB in my computer. I did't define any password and username for the installation. I can see everything with Robo 3T.
Now I want to protect my database.
I have tried to set authentication for the database. I followed https://docs.mongodb.com/manual/tutorial/enable-authentication/ . It did not work.
I still can reach mongodb with robo 3t and see all information.
I have also tried to start mongodb with --auth parameter. I have define a configuration file looks like
And for starting mongodb
mongod -f C:\mongodb\conf\mongodb.conf
Mongodb has been started but, it did not ask any pass. And I can save simple data with Postman without authentication.
What I want to do:
Protect my database against Robo 3t. :))
I dont want to save any data without auth.
Building Nodejs connection string that include pass like
mysql://root:password#localhost:port/dbName
Here is my Nodejs index.js code
this is my model.
PS: I am very new in Nodejs and Mongodb.
EDIT: inside conf file
I'm working on a project where I need to have multiple node clients connect to a node server via websockets. The clients will send files to the server and the server will immediately distribute that file to all connected clients.
The problem I'm running into is connecting as a client in node. The built in ws module seems to only support server use. I've also tried the npm websocket client which allows me to use node as a client but I seem to only be able to send binary data without any other information like the filename, etc. using the sendBytes method.
Thanks for any suggestions.
Checkout the delivery package of npm.
It provides bi-directional file tranfer for node.js over socket.io.

I am studying the MEAN stack by using this tutorial. But the tutorial connects to a remote mongodb installation. I have MongoDB running in the CentOS7 localhost.
How do I alter the mongoose connect line in server.js from the tutorial link above to connect to a localhost database instead of a remote database?
Here is the current line from server.js that needs to be changed to point to the localhost mongodb:
mongoose.connect('mongodb://node:nodeuser#mongo.onmodulus.net:27017/uwO3mypu');
A specific mongodb database has not been created yet. Do I need to create that also?
I'm fairly new at Mongo to, but I know how to connect to a local db. Basically I had to do the following:
Download the latest version of mongodb from https://www.mongodb.com/download-center?jmp=nav#community (according to your settings)
Once installed, I've created a folder that will be containing my DB.
Use a command line instance to start mongo like this:
mongod --dbpath [YOUR_DB_PATH]
Created a DB use mydb
With that you should have already a mongodb db instance looking for connections on default port. So you can change that line for this:
mongoose.connect('mongodb://localhost:27017/mydb');
Again, this is really basic and it is creating a mongo DB connection with all default options. So this will keep you rolling, but you may need to dig a bit more for custom options.
Hope this helps
