Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:01,060 --> 00:00:02,590
Our common service is all complete.
2
00:00:02,590 --> 00:00:05,330
So let's very quickly do a quick test using postmen.
3
00:00:05,350 --> 00:00:07,670
I'm going to put that go in my terminal to get started.
4
00:00:07,670 --> 00:00:13,300
I'm going to find my terminal window that is inside that comments project directory and I'll run NPM
5
00:00:13,300 --> 00:00:15,130
start inside there.
6
00:00:15,250 --> 00:00:20,500
Now once you recall that we now have two separate services two separate express applications running
7
00:00:20,500 --> 00:00:21,410
on our machine.
8
00:00:21,460 --> 00:00:25,490
One is listening on Port 4000 the others listening on port four thousand one.
9
00:00:25,840 --> 00:00:27,730
So we want to communicate with our common service.
10
00:00:27,730 --> 00:00:32,760
We need to make a request to local host or thousand and one all right.
11
00:00:32,790 --> 00:00:37,230
So now that that is running let's flip over to postman.
12
00:00:37,420 --> 00:00:40,800
I'm going to open up a new request tab right here.
13
00:00:40,900 --> 00:00:45,480
I'm going to make a post request because I want to try to create a comment just to get started.
14
00:00:46,090 --> 00:00:51,550
I'm gonna put in my local host four thousand and one again four thousand one because we want to reach
15
00:00:51,550 --> 00:00:52,570
out to our comments.
16
00:00:52,570 --> 00:00:56,860
Service and we'll make a request to slash posts.
17
00:00:56,900 --> 00:01:01,580
The idea of a postal we want to add a comment to now our comment service right now it doesn't really
18
00:01:01,580 --> 00:01:07,880
have any idea of what valid post ideas are so we can put in any post ideas right here that we want to.
19
00:01:07,880 --> 00:01:08,830
Any string whatsoever.
20
00:01:08,870 --> 00:01:10,730
I'm going to put in just one two three.
21
00:01:10,760 --> 00:01:18,550
That's gonna be the idea of the post that we're going to imagine actually exists and then flash comments.
22
00:01:18,590 --> 00:01:19,930
Next up I'll go to headers.
23
00:01:20,000 --> 00:01:30,790
I'm gonna put in a content type of application slash Jason I'll then go to body I'll select raw I'm
24
00:01:30,790 --> 00:01:37,660
going to make sure the dropdown is set to Jason and I will enter in some Jason right here remember a
25
00:01:37,660 --> 00:01:44,950
comment must have a content property so I'll give my comments some content or something like I am a
26
00:01:45,230 --> 00:01:51,420
comment I'll go ahead and send this thing off and there we go.
27
00:01:51,420 --> 00:01:57,030
I've got a two a one created and you'll notice the inside of our response we've got an array of comments
28
00:01:57,300 --> 00:02:04,020
that are associated presumably with post that has ideas One two three EPs that looks good now let's
29
00:02:04,020 --> 00:02:10,970
make sure that we can retrieve all of our comments with some given post as well I can open up another
30
00:02:10,970 --> 00:02:19,670
request Tab I'm gonna make a get request to a local host four thousand and one post and I want to get
31
00:02:19,700 --> 00:02:27,610
all the comments that are associated with Post One two three flash comments then once again on the headers
32
00:02:27,610 --> 00:02:29,530
tab content
33
00:02:33,130 --> 00:02:41,120
of application Jason we don't need a body because we are making a get request so I'll go ahead and send
34
00:02:41,510 --> 00:02:46,310
I get a two hundred OK and there is my array of comments right there just to make sure this is all working
35
00:02:46,310 --> 00:02:50,370
correctly let's try to add in just one more comment make sure that we don't overwrite any comment or
36
00:02:50,370 --> 00:02:56,670
anything like that so I got to go back over to my post request tab right here I'll change the content
37
00:02:56,730 --> 00:03:05,660
to second comment I'll send it off I can now see inside the response and I've got two comments here
38
00:03:05,720 --> 00:03:10,990
one that says I'm a comment dealer says second comment and then I go to my get request tab I can make
39
00:03:10,990 --> 00:03:13,630
the request again and yeah there we go.
40
00:03:13,630 --> 00:03:14,910
Very good.
41
00:03:15,040 --> 00:03:15,310
All right.
42
00:03:15,340 --> 00:03:22,420
So that is it for the very basic very simple express J.S. stuff that's all we're going to really write
43
00:03:22,900 --> 00:03:27,910
as far as like simple express stuff goes we're not going to take a pause we're gonna come back the next
44
00:03:27,910 --> 00:03:32,890
video and start working on that react application and once we finish that thing up very quickly we're
45
00:03:32,890 --> 00:03:38,700
then going to start to see some really big issues start to crop up with our current design.
46
00:03:38,700 --> 00:03:41,980
There is some really going to hit in nasty stuff inside of here.
47
00:03:42,070 --> 00:03:45,540
Maybe it's not the worst stuff in the world but it's definitely not very efficient.
48
00:03:45,640 --> 00:03:47,680
It's going to start to put that react application together.
49
00:03:47,740 --> 00:03:51,880
We're gonna start to see some problems with our implementation and then we're gonna start to figure
50
00:03:51,880 --> 00:03:55,700
out how we can solve these things with a micro services style approach.
51
00:03:55,710 --> 00:03:57,340
So a quick pass see you in just a minute.
