Solution: Clearing Cookies and Redirecting

1:55 with Andrew Chalkley and Joel Kraft

A solution to the challenge from the last video.

How did it go? 0:00
Don't feel bad if you weren't able to complete it all. 0:01
Even if you got some of the features completed, you did well. 0:04
Now, I'll go over how I created the goodbye button. 0:07
To create the button itself, 0:12
I've added a form to the index.pug file right under the greeting. 0:14
I set its action to /goodbye which is the new goodbye route. 0:21
The method is post and in the form I've got one submit button. 0:27
It has the text goodbye. 0:34
In app.js I added a new post route under the hello post route called goodbye. 0:38
I use the clear cookie method to remove the cookie's username value, 0:48
then I redirected to the hello route. 0:53
Let's see what we have in the browser now. 0:58
I go to the Hello route and then I type in my name and hit enter. 1:02
I'm redirected to the Home route and my name is displayed. 1:09
Notice I can't get to the Hello route anymore. 1:14
And here's the Goodbye button I implemented. 1:20
If I click it, I'm redirected to the Hello page. 1:24
If I try and visit the index route, I'm redirected to the Hello page. 1:30
Great, now we have the app that stores and 1:37
erases the cookie, it also redirects based on the cookies value. 1:39
We've covered a lot of ground in this process. 1:44
Well done for sticking with it. 1:47
Next up, let's dive deeper into a fundamental feature of Express, 1:49
called Middleware. 1:53
See you there. 1:54
