The delete route is going to be
a lot like the update quote route,
0:00
only it will completely remove
the specified quote from the data store.
0:04
To create a delete route,
0:08
we'll want to handle delete requests
sent to the slash quote slash ID route.
0:09
Again, we'll need the callback to be
an asynchronous function that takes in
0:18
the request and response objects.
0:21
And to use the async await syntax,
0:28
we'll need a try-catch block.bbb
Inside the catch block,
0:31
we'll copy and paste the same error
handling code from previous videos.
0:36
Inside the try block, we'll again get the
specified quote by grabbing the ID from
0:46
the request parameters and
passing it to the get quote function.
0:50
Once we’ve got the quote
we’re looking for,
1:03
we can use the delete quote
method from our records module.
1:05
We'll wanna wait for the delete quote
method to finish before we send back
1:13
the proper status message and
end the request.
1:17
We'll send back the same
no content status message.
1:26
Let's save this and
take a peek inside of our data store.
1:30
From testing and such,
I have several duplicate quotes to delete.
1:34
Go to postman and send a delete request to
the ID of the quote you want to delete.
1:38
So I want to delete quote 1492.
1:45
Send.
1:51
And close this for now.
1:53
Let's see if we can figure
out what went wrong here.
1:56
I can see I have a typo in my route.
1:59
So let's try this again.
2:03
And we've got a 204
No Content status code.
2:05
Great, let's take a look inside data.json.
2:08
And that quote is gone.
2:13
For practice, I encourage you to look
at the put route we did in a previous
2:15
video,and implement some extra additional
error handling for our delete route.
2:19
What if the client requests to
delete a quote that doesn't exist?
2:25
Well done.
2:29
We now have a fully functioning rest
API with all of its cred operations.
2:30
We can create, read,
update, and delete quotes.
2:34
You may have noticed that we have quite
a bit of unwieldy and repeating code.
2:37
In the next part of the course,
we'll use express middleware to clean up
2:41
some of our repeating code,
see ways to structure our projects so
2:45
that our code is more modular, and
learn how we can handle errors globally.
2:48
And of course, we'll write a route
that returns a random quote.
2:52
I'll see you there.
