Adding Log In Routes

1:39 with Dave McFarland and Jonathan Foster

In this video add routes to for the application's log in functionality, including a GET route to display the form and a POST route to handle form submissions.

To provide a way to login, 0:00
we'll need to add a login form, as well as a way to process the form input. 0:02
We'll need two routes on the same /login URI. 0:06
One route to display the login form, 0:11
the other to process the login credentials posted from the form. 0:13
I'll add those routes to the index.js file inside the routes directory. 0:17
The first route to load the login form is simple. 0:23
It's similar to the route we added for the registration form. 0:26
We set up a GET request along the /login route. 0:29
Then we add a callback function. 0:34
This function will render a pug template. 0:41
We'll build the pug template in the next video, but you can see that this 0:44
function follows this same structure as many of the other routes in this file. 0:47
It identifies the name of the pug template, login, 0:51
and passes along a parameter, the title of the page. 0:57
Now when the user fills out the login form, 1:03
the data is posted to the /login route. 1:05
So, let's add a POST route. 1:09
Now, there's gonna be a little bit more programming required than what I'm 1:13
showing you here. 1:17
We'll need to hash the submitted password and 1:18
compare that with records in our Mongo database. 1:21
I'll show you how to do that a little later. 1:24
So for now, let's send back a simple message just so 1:26
we can test the route is working. 1:29
The routes are in place, but we'll need the login form to test them. 1:31
So, in the next video, I'll show you how to build the login templating form. 1:35
