Connect MongoDB to NodeJS Server

Hello, people of Hive in this guide, we will keep learning how to use MongoDB and in this case we see how to connect the Database we created with our NodeJS server, if you don't know how to create a database check the last guide I posted where I created a new database from 0.

First, we go to the main Dashboard inside the MongoDB console, we already saw this in the last post, here we will click on the green connect button, if you have not created the database, it's really easy to go for the free deployment or check the last post. Also check the Network Configuration we made to allow 0.0.0.0/0 so we don't need to worry about IPs right now, just for testing this is not a problem for security, but for real deploys you need to check that.

We will see these options and a lot more, select the first that says Drivers, and you can see it says that it's compatible with NodeJS and other Frameworks, also Compass is a great tool it's the Desktop Version of MongoDB but we don't need to download any software that's an advantage of using MongoDB console in the web, we can access like any cloud service.

Now we see this info, here we need to select NodeJS and version as it shows in the picture, the install driver we can ignore because we will use Mongoose instead of Mongodb, we will see more in the next guides about the difference. And we need to copy this link we see in the third point, that's the link we will use in our NodeJS to connect to the Databse.

Finally, we need to edit our NodeJS server.js as we see next, we need to change the link with the link we got from our mongoDB previous step, we also need to npm install, express, mongoose, and body-parser, we will see the server.js again in the next guide, but with this, we can start the express server and we connect to the database we created.

In the next guides we will see how to interact with the database and we will complete with each step the NodeJS code, right now we have our database and server ready to start creating some Data and functions to interact with the server and Database.
