1
00:00:00,310 --> 00:00:01,390
How did it go?

2
00:00:01,390 --> 00:00:04,440
Don't feel bad if you weren't
able to complete it all.

3
00:00:04,440 --> 00:00:07,850
Even if you got some of the features
completed, you did well.

4
00:00:07,850 --> 00:00:10,820
Now, I'll go over how I
created the goodbye button.

5
00:00:12,450 --> 00:00:14,778
To create the button itself,

6
00:00:14,778 --> 00:00:20,090
I've added a form to the index.pug
file right under the greeting.

7
00:00:21,370 --> 00:00:27,820
I set its action to /goodbye
which is the new goodbye route.

8
00:00:27,820 --> 00:00:32,771
The method is post and
in the form I've got one submit button.

9
00:00:34,488 --> 00:00:36,345
It has the text goodbye.

10
00:00:38,121 --> 00:00:46,810
In app.js I added a new post route under
the hello post route called goodbye.

11
00:00:48,130 --> 00:00:52,140
I use the clear cookie method to
remove the cookie's username value,

12
00:00:53,610 --> 00:00:57,080
then I redirected to the hello route.

13
00:00:58,470 --> 00:01:00,740
Let's see what we have in the browser now.

14
00:01:02,530 --> 00:01:07,173
I go to the Hello route and
then I type in my name and hit enter.

15
00:01:09,336 --> 00:01:14,640
I'm redirected to the Home route and
my name is displayed.

16
00:01:14,640 --> 00:01:17,550
Notice I can't get to
the Hello route anymore.

17
00:01:20,500 --> 00:01:22,720
And here's the Goodbye
button I implemented.

18
00:01:24,960 --> 00:01:29,190
If I click it,
I'm redirected to the Hello page.

19
00:01:30,200 --> 00:01:35,230
If I try and visit the index route,
I'm redirected to the Hello page.

20
00:01:37,000 --> 00:01:39,690
Great, now we have the app that stores and

21
00:01:39,690 --> 00:01:43,780
erases the cookie, it also redirects
based on the cookies value.

22
00:01:44,820 --> 00:01:47,370
We've covered a lot of
ground in this process.

23
00:01:47,370 --> 00:01:49,440
Well done for sticking with it.

24
00:01:49,440 --> 00:01:53,500
Next up, let's dive deeper into
a fundamental feature of Express,

25
00:01:53,500 --> 00:01:54,530
called Middleware.

26
00:01:54,530 --> 00:01:55,030
See you there.
