1
00:00:00,975 --> 00:00:04,140
-: In the last section, we got MongoDB up and running.

2
00:00:04,140 --> 00:00:06,300
Just to make sure we're on the same page here

3
00:00:06,300 --> 00:00:09,630
in my terminal, I've got MongoDB very clearly running

4
00:00:09,630 --> 00:00:11,910
by executing the command MongoD.

5
00:00:11,910 --> 00:00:12,960
So at this point in time

6
00:00:12,960 --> 00:00:16,320
we wanna make sure that Mongo is running in a separate tab.

7
00:00:16,320 --> 00:00:17,220
I'm gonna flip back over

8
00:00:17,220 --> 00:00:20,910
to the tab that's hosting Node Mon right now

9
00:00:20,910 --> 00:00:23,333
and then I'm just gonna go back to my code editor.

10
00:00:24,570 --> 00:00:25,530
So at this point in time

11
00:00:25,530 --> 00:00:29,280
we've set up Mongoose with the one single model.

12
00:00:29,280 --> 00:00:33,900
We've got Mongoose running, we've got MongoDB running.

13
00:00:33,900 --> 00:00:38,100
There's just maybe one last missing tiny piece in here.

14
00:00:38,100 --> 00:00:41,460
So we have Mongo- Mongoose running on our server,

15
00:00:41,460 --> 00:00:44,520
but we actually have not formed a distinct connection

16
00:00:44,520 --> 00:00:47,340
between Mongoose and the MongoDB server

17
00:00:47,340 --> 00:00:49,260
that we're running host locally.

18
00:00:49,260 --> 00:00:52,080
So by default, Mongoose does not try to reach

19
00:00:52,080 --> 00:00:53,790
out to your local host and connect

20
00:00:53,790 --> 00:00:57,240
to just any old MongoDB server that's sitting there.

21
00:00:57,240 --> 00:00:59,880
We have to specifically tell it, hey, Mongoose

22
00:00:59,880 --> 00:01:03,093
please go connect to this instance of MongoDB.

23
00:01:04,739 --> 00:01:06,960
To do so, we need to write some setup code

24
00:01:06,960 --> 00:01:09,900
inside of our index.js file.

25
00:01:09,900 --> 00:01:14,900
So inside index.js, I'm going to require Mongoose.

26
00:01:18,330 --> 00:01:19,710
And I'm gonna make another new section

27
00:01:19,710 --> 00:01:22,083
in here called DB setup.

28
00:01:23,310 --> 00:01:25,470
And this is where we're going to tell Mongoose,

29
00:01:25,470 --> 00:01:30,300
hey go connect to this very particular instance of MongoDB.

30
00:01:30,300 --> 00:01:34,410
I'm gonna say Mongoose.connect and then we're gonna

31
00:01:34,410 --> 00:01:37,290
essentially pass it a URL of sorts here.

32
00:01:37,290 --> 00:01:42,290
We're gonna say MongoDB colon slash slash local host.

33
00:01:44,670 --> 00:01:49,547
That means on this server, and then colon auth slash auth.

34
00:01:52,980 --> 00:01:55,560
Internally, this creates a new database inside

35
00:01:55,560 --> 00:01:57,630
of MongoDB called auth.

36
00:01:57,630 --> 00:01:59,340
So if you want to call your database something

37
00:01:59,340 --> 00:02:01,530
slightly different, this would be where you'd change it.

38
00:02:01,530 --> 00:02:02,373
Just right here.

39
00:02:03,930 --> 00:02:06,060
I'm gonna save this file

40
00:02:06,060 --> 00:02:11,060
and now I'm going to Node mon just reran.

41
00:02:11,370 --> 00:02:13,980
So Node mon just node mon just restarted.

42
00:02:13,980 --> 00:02:16,800
I'm gonna flip back over to my Mongo process now

43
00:02:16,800 --> 00:02:19,440
and you can see that I've had several connection accepted

44
00:02:19,440 --> 00:02:21,240
from blah, blah, blah.

45
00:02:21,240 --> 00:02:22,620
Let's go ahead and see what happens

46
00:02:22,620 --> 00:02:25,140
if I kill the Node mon instance that's running.

47
00:02:25,140 --> 00:02:27,270
So I'm gonna flip back over to Node mon

48
00:02:27,270 --> 00:02:30,093
and I'm gonna hit Control C just to stop.

49
00:02:31,320 --> 00:02:34,440
Then I'm gonna go back over to Mongo, and sure enough

50
00:02:34,440 --> 00:02:38,040
I get end connection from 12701.

51
00:02:38,040 --> 00:02:41,370
So that is the server that we were just running.

52
00:02:41,370 --> 00:02:43,740
So we had made a connection with Mongoose

53
00:02:43,740 --> 00:02:47,010
and by ending it, we close the connection.

54
00:02:47,010 --> 00:02:49,260
I'm now gonna go back over to the server.

55
00:02:49,260 --> 00:02:51,303
I'm gonna run NPM run Dev again.

56
00:02:53,670 --> 00:02:56,280
Server starts up, I'm gonna go back over

57
00:02:56,280 --> 00:03:00,563
to MongoDB and connection accepted from 12701.

58
00:03:01,560 --> 00:03:03,930
Perfect. So that means that our server, you know

59
00:03:03,930 --> 00:03:06,300
we've got reasonable belief at this point that

60
00:03:06,300 --> 00:03:10,263
our server is making connection with our MongoDB instance.

61
00:03:11,340 --> 00:03:12,390
So this is fantastic.

62
00:03:12,390 --> 00:03:15,300
There is one more little interesting thing that I

63
00:03:15,300 --> 00:03:17,100
wanna show you guys about MongoDB

64
00:03:17,100 --> 00:03:18,240
that we're going to make a lot

65
00:03:18,240 --> 00:03:20,073
of use of in the coming sections.

66
00:03:21,480 --> 00:03:23,430
Right now when we run MongoDB

67
00:03:23,430 --> 00:03:24,780
it's just running the command line, right?

68
00:03:24,780 --> 00:03:26,160
We can't really see any, any

69
00:03:26,160 --> 00:03:27,930
of the data in here or anything like that.

70
00:03:27,930 --> 00:03:30,540
It would be really fantastic for debugging though

71
00:03:30,540 --> 00:03:32,250
if we could kind of reach directly

72
00:03:32,250 --> 00:03:35,400
into the database and see what records we have.

73
00:03:35,400 --> 00:03:39,000
So there's a fantastic tool that we can download

74
00:03:39,000 --> 00:03:40,470
to do this for us.

75
00:03:40,470 --> 00:03:42,540
It's called Robo Mongo.

76
00:03:42,540 --> 00:03:47,073
So in my browser, I'm going to search for Robo Mongo.

77
00:03:49,200 --> 00:03:51,270
And then the first result on here

78
00:03:51,270 --> 00:03:55,770
I'm gonna find robomongo.org.

79
00:03:55,770 --> 00:03:58,833
I'm gonna go this page at the top right, I'll find download.

80
00:04:00,510 --> 00:04:04,020
And now by default, Robo Mongo is going to ask you

81
00:04:04,020 --> 00:04:06,900
to download the latest version right here at the top.

82
00:04:06,900 --> 00:04:08,850
And if you wanna download the latest version

83
00:04:08,850 --> 00:04:11,250
you have to buy it to download it.

84
00:04:11,250 --> 00:04:12,510
But if you don't wanna spend money

85
00:04:12,510 --> 00:04:15,570
and I don't blame you, if you don't, no problem.

86
00:04:15,570 --> 00:04:17,970
You can download older versions of it.

87
00:04:17,970 --> 00:04:20,459
And basically we're talking about just the, you know

88
00:04:20,459 --> 00:04:23,070
most recent version for free.

89
00:04:23,070 --> 00:04:26,040
So only the latest version you have to pay for,

90
00:04:26,040 --> 00:04:27,990
previous versions you can get for free.

91
00:04:28,860 --> 00:04:31,260
So I'm going to download this

92
00:04:31,260 --> 00:04:33,570
and whatever platform you're on, just go ahead

93
00:04:33,570 --> 00:04:35,970
and download and then go ahead and install it.

94
00:04:35,970 --> 00:04:38,520
So at this point, I encourage you to pause the video

95
00:04:38,520 --> 00:04:40,833
and go through the installation process.

96
00:04:47,370 --> 00:04:49,890
Once you've got Robo Mongo working

97
00:04:49,890 --> 00:04:51,840
let's go ahead and start it up.

98
00:04:51,840 --> 00:04:56,280
So I'll run, oops, Robo Mongo to start it.

99
00:04:56,280 --> 00:04:57,600
I've already got an instance running.

100
00:04:57,600 --> 00:05:00,333
Sorry about that. Let's restart. There we go.

101
00:05:02,610 --> 00:05:05,040
So by default, when you first open Robo Mongo

102
00:05:05,040 --> 00:05:07,890
you won't have any connections listed in here

103
00:05:07,890 --> 00:05:09,960
so I'm just gonna remove my connection just

104
00:05:09,960 --> 00:05:11,943
so we look the same. Very good.

105
00:05:13,320 --> 00:05:15,750
Now, the connections that these are references

106
00:05:15,750 --> 00:05:17,880
to a connection is a connection

107
00:05:17,880 --> 00:05:20,790
to an actual MongoDB database.

108
00:05:20,790 --> 00:05:23,343
So I'm going to create a new connection.

109
00:05:24,480 --> 00:05:26,640
The default settings in here are fantastic,

110
00:05:26,640 --> 00:05:29,370
so we don't really have to change these default settings.

111
00:05:29,370 --> 00:05:30,840
I will change the name, however,

112
00:05:30,840 --> 00:05:31,680
I'm just gonna change the name

113
00:05:31,680 --> 00:05:34,710
to local host just to make it clear that, hey

114
00:05:34,710 --> 00:05:36,960
I'm running this on the local host right now.

115
00:05:37,950 --> 00:05:41,460
I'm gonna save this and makes a new record

116
00:05:41,460 --> 00:05:42,860
and then I'll connect to it.

117
00:05:46,710 --> 00:05:50,010
On the left hand side, I've got a database called auth.

118
00:05:50,010 --> 00:05:52,860
I'll expand on that, and then I expand collections.

119
00:05:52,860 --> 00:05:54,120
And you can see I've already got a little bit

120
00:05:54,120 --> 00:05:55,140
of data loaded in here.

121
00:05:55,140 --> 00:05:56,340
That's totally fine.

122
00:05:56,340 --> 00:05:58,620
Chances are you just have an auth

123
00:05:58,620 --> 00:06:00,180
or maybe not even auth at all.

124
00:06:00,180 --> 00:06:03,360
So as long as you can see essentially local hosts

125
00:06:03,360 --> 00:06:06,063
and system over here, you should be good to go.

126
00:06:07,470 --> 00:06:09,240
Now that we've got Robo Mongo set up

127
00:06:09,240 --> 00:06:11,760
let's go onto the next section, create some new data

128
00:06:11,760 --> 00:06:14,670
inside of our database, and then we can verify it inside

129
00:06:14,670 --> 00:06:17,130
of Robo Mongo and just see it in action.

130
00:06:17,130 --> 00:06:18,930
So I'll see you in the next section.
