00:00:00,210 --> 00:00:05,850
In this hour, we are going to talk about the mongoose and we were going to use the mongoose, but what

2
00:00:05,850 --> 00:00:06,510
is Mongoose?

3
00:00:06,510 --> 00:00:12,000
Mongoose provide a straightforward schema based solution to the models of applications.

4
00:00:12,240 --> 00:00:20,680
And Bongo is a Jimenez and Mongoose schema is a document data structure that is enforced.

5
00:00:20,850 --> 00:00:27,690
We had an application data, their schema pairwise, what properties it should have and types of properties.

6
00:00:27,930 --> 00:00:31,410
In our case, we are working with items.

7
00:00:31,440 --> 00:00:39,010
So we have a schema for an item that have two properties and one is the name and the other is the price.

8
00:00:39,930 --> 00:00:46,720
Models are the fancy constructor come apart from the schema definitions and instead of a model is called

9
00:00:46,720 --> 00:00:55,290
a documents and models are responsible for creating and reading documents from the underlying Mongo

10
00:00:55,290 --> 00:00:56,230
DB database.

11
00:00:56,760 --> 00:01:03,990
So in this documentation, you can see we can use the model to construct the documents by using the

12
00:01:03,990 --> 00:01:05,450
model box safe.

13
00:01:05,460 --> 00:01:11,520
And we can also do some search, for example, by using the fight or flight by IP.

14
00:01:11,730 --> 00:01:19,750
We can also delete a document and of course, we can also update the document and the back to our project.

15
00:01:20,100 --> 00:01:27,140
We already have the link of the Mongo DB and first of all, we have to install the mongoose.

16
00:01:27,240 --> 00:01:32,100
So we have to use NPM install both.

17
00:01:34,810 --> 00:01:45,370
First, we are going to impose the mongoose by using the constant mongoose is going to require mongoose

18
00:01:45,940 --> 00:01:52,180
and then we type Mongoose thought on that, the Mongo DB.

19
00:01:53,760 --> 00:02:01,560
And since this is a MySpace and so we can use then and every little dialogue connected.

20
00:02:03,220 --> 00:02:10,260
And then we used to catch error and also thought Laub error.

21
00:02:10,840 --> 00:02:16,210
Now we can go to the terminal and start the server again by using the phone app.

22
00:02:16,750 --> 00:02:22,450
Now, you can see there are some warnings here and we also have to connect to this.

23
00:02:22,730 --> 00:02:31,690
So actually we can connect to the database already, but it is better to costis options to stop the

24
00:02:31,690 --> 00:02:32,260
warning.

25
00:02:32,470 --> 00:02:36,580
So we paste it to our mongoose stock on that.

26
00:02:36,580 --> 00:02:39,340
And we also copied this one.

27
00:02:41,180 --> 00:02:50,870
And here, so we save it and now you can see the Collinet and we don't want to listen to requests until

28
00:02:50,870 --> 00:02:52,240
the conversion is complete.

29
00:02:52,250 --> 00:02:57,860
So it is also better to take this and pass it inside the brocke.
