All language subtitles for 006 Setting Up A MongoDB Database_Downloadly.ir_en

So now that we added our API routes

or the newsletter in for the comments

and that we wired up

those front-end components for the newsletter

and for the comments.

Now that all of that was done.

It's time to work on the logic inside of the API routes

because at the moment we don't do anything in there.

In the newsletter API route we're

just logging the entered email

and in the comments API route

for the post case,

we also in the end,

just log our comment here.

And that of course is not too helpful.

That's not the goal.

Instead, we wanna store that data more permanently

and we could of course use a file for that.

We could re-add a data folder

in our project with some JSON

or a text file and write that data to that file.

But I would argue it's more realistic to use a database

and therefore that's what we'll do.

I'll use a real database here.

I'll use MongoDB.

MongoDB of course is just one option.

It's not a must use option,

but I will use it because using MongoDB

with Node.js is particularly easy

and it's also a production ready,

scalable database which is a great choice

for pretty much all projects.

For a lot of projects, Let's put it like this.

And that's why we'll use MongoDB.

Even better than that, we can get started for free.

If you visit MongoDB.com and you go to pricing,

you'll see that they have various offerings

and we will use the cloud service here,

MongoDB Atlas.

That is their fully managed cloud database service,

which we can use without setting up anything

on our local system, which is great.

And we can get started for free here,

which is awesome.

So we can click on start free here actually.

Or in the top right corner,

click on Try Free,

click on Cloud

and then get started for free here by signing up.

just fill out these basic details and sign up.

I already do have an account

so I will log in with that.

And once you did sign up and log in,

you should be greeted with some screen

that looks something like this.

You should be able to build a cluster

and then there use a shared cluster.

So, create a cluster here

where you can get started for free.

No, a cluster is basically a server.

You could say,

which will then later host your databases,

you could say.

Now here we need to choose a cloud provider

which will be used under the hood.

And we can stick to AWS here

and basically keep the defaults

for a cluster tier let's stick

to the M0 Sandbox since that's available for free.

And for the additional settings,

we also can stick to the defaults

and we can also keep that default cluster name

and create that cluster.

Now, this will set up this database cluster

which will then enable us to connect

to this cluster and store data

in the databases there.

And using it will be super simple.

Now, whilst this is getting set up,

we can go back to our project already

and quit the dev server

and install an extra package

with npm install.

Because in order to communicate

with MongoDB and to send queries to MongoDB,

we need to install a new third party package.

If you search for Node.js MongoDB,

you also find it on npm.

It's this MongoDB package

which is the official driver for MongoDB.

So that makes connecting and talking

to the Mongo DB database super easy then.

So we should install MongoDB,

this MongoDB package here like this

with npm installed MongoDB.

And this will install this third party package

which we'll then use in our server side code

to talk to MongoDB to our cluster

and to store data and

to fetch data as well Of course.

And the important thing here really is

that we'll use it in our server side code.

So in these API routes,

we will not use this Mongo DB package

in any client side code.

A, because it's not optimized for that.

It might not even work there because there

is a high chance that it uses Node.js APIs internally

and b, even if it does work in the browser,

it would be a security issue.

Because for talking to the database,

we will need to plug our credentials

into the code and we don't wanna do

that in any code our users can see

because they could then abuse those credentials

to hack into our database.

That's why we want to run such database code only

on the server side.

So, only in our API routes.

Now connecting to the cluster is done here now.

And when we clicked on Connect,

we can choose connect your application.

And we see code which we can use to connect

to our MongoDB cluster with the Node.js driver here.

And that's what we're going

to do in the next lectures.
