Define User Registration Routes
3:52Use Express's built in router to add a GET route to display a registration form and a POST route for collecting user registration information.
[MUSIC]
0:00
A major part of any user authentication
system is the registration process.
0:04
After all, you can't very well
authenticate a user's identity
0:09
until you've added a way to capture and
store user information.
0:12
In this section of the course
I'll show you how to create
0:16
a registration form that
connects to a Mongo data store.
0:19
Users will be able to
sign up on your site and
0:22
their information will be
added to the database.
0:25
First let's define the routes users will
take to see the registration form and
0:28
submit the registration information.
0:32
We already have three
routes in our application.
0:35
We'll add two more routes now.
0:38
They use the same URI or
endpoint, /register.
0:40
When the user requests that
endpoint using the HTTP GET method,
0:44
they'll see the registration form.
0:48
When they use POST to send their sign
up information to that same endpoint,
0:50
the application will add
that data to the database.
0:54
Let's program these routes now.
0:58
We have some basic routes already
defined in the routes directory
1:01
in the file called index.
1:05
js.
1:06
I'll start by adding a get route
to display the registration form,
1:08
router.get and then we pass it a string
/register, that's the end point.
1:12
We had a callback function
as the second argument,
1:21
the callback tells Express what to do
when a user requests this end point.
1:24
It accepts three arguments, the request
object which has all the information
1:29
related to the request that was sent
from the client, the response object
1:33
which lets us send data back to the user,
and a function called next
1:38
which tells express to continue on
to the next piece of middleware.
1:43
In other words, what function should
Express run after this callback?
1:47
I'll talk more about next in
middleware later in this course.
1:51
So if those are new concepts to you,
don't worry about them for now.
1:54
For this route we're not
concerned about the requests.
1:57
The user is just asking for
the registration form.
2:00
So we use the response.
2:03
That's the res parameter here,
to send back our response.
2:05
Because we haven't created
the registration form yet,
2:09
let's just send back a message
to see if the route works.
2:11
Let's check it out.
2:22
I'll save this file.
2:23
And switch to my terminal or
console program.
2:25
I need to make sure I'm
in the correct directory.
2:28
So I'll print out my working
directory by typing pwd.
2:30
If you're using the Windows console
you can use the cd command.
2:34
Then I'll start the app
by typing node app.js.
2:39
This will start the express app and
2:45
keep the process running
in this terminal window.
2:47
The apps running on a local
host using port 3000.
2:50
I'll open a web browser and
enter localhost:3000.
2:52
When I click the Sign Up button I'm
routed to the /register endpoint.
2:58
And I see the Register today!
3:06
message.
Great, that route's working so
3:07
let's add a post route.
3:09
The post route to register
is where we receive
3:09
the information entered
into the registration form.
3:15
We'll use that data to create
a new user in the database.
3:19
Again.
3:33
Let's use res.send with a simple text
message, so that we can test this route.
3:33
Unfortunately, we can't test it yet, we
need to create a registration form first.
3:38
Then we'll be able to post
information to this route.
3:43
We'll build that form soon.
3:45
But first let me teach you two other
ways to start up an express application.
