Checking For and Populating an Authenticated User
In this lesson, we'll create a silent auth middleware that will automatically check whether a request has an authenticated user attached to it, and populate that user's details if one is found.

Checking For and Populating an Authenticated User
-
[MUSIC]
-
Since the navigation is used on every page that we render with our application,
-
we're gonna need the authenticated user on almost every request that our server
-
receives.
-
So it would be great to go ahead and just check for
-
that authenticated user out the get go using a middleware.
-
So let's move this auth check out of our view and
-
into a router level middleware.
-
Because if we haven't found a route specifically for the user,
-
then we don't care whether or not the authenticated user is there or not.
-
So we don't care about it at the server level, but it would be nice to have this
-
automatically happen for every route that we do have defined.
-
So we can do it at the router level so
-
that it runs for every route that we have registered.
-
So let's hide our text editor away, jump into our terminal, and
-
let's stop our server, clear that out.
-
And let's create a new middleware with node ace make middleware.
-
We'll keep with the naming convention from AdonisJS 5 and
-
call this our silent auth middleware.
-
Hit Enter there.
-
It's gonna ask us which stack we wanna register this middleware for.
-
As we just discussed, we're wanting it for our router since we don't really care
-
about whether or not we have an authenticated user at the server level,
-
where we may or may not have a route matching.
-
So we'll create this at our router level, and there we go.
-
So now we have a silent auth middleware registered.
-
And since we've made this with the acli,
-
it's added it to that start kernels file for our registered route middleware.
-
Let's boot our server back up while we're here and hide this away,
-
jump back into our text editor.
-
And while we're here, let's switch this back to just checking if we have an auth
-
user.
-
With that change, let's dive into our new silent auth middleware.
-
Here we see our brand new middleware,
-
looks exactly like the others that we've looked at so far.
-
We have our next call right here.
-
And since we want to check for the authenticated user and
-
have that be prepared for our route handler,
-
we're going to want to perform that check before that next function call.
-
So we can get rid of this console log right here, and
-
we're provided our CTX or our HTTP context as our parameters.
-
We can do await CTX auth and call that check method here.
-
Give that a save, and that's all that we should need to do there.
-
Remember, we've just changed this back to just checking auth user.
-
So with our silent auth now making that check globally for
-
all registered routes that we have inside of our application.
-
If we dive back into our browser at this point,
-
it just refreshed itself and we still have our auth user.
-
If we dive into our writers, we still have our auth user.
-
Directors still have our auth user.
-
A specific director, it's still there.
-
So it's checking it for each and every route that we have.
