Firebase makes user authentication incredibly easy to implement in Angular, but the one drawback is that it's not easy to implement custom data on the auth object itself.
In this episode, I'm going to show you how to implement an OAuth system from scratch using AngularFire version 5 and also save custom user data to the Firestore database.
In addition, we're going to set up a router guard that will prevent unauthorized users from accessing certain routes.
I recommend that you follow along with the source code on angularfirebase.com, and make sure to subscribe to the channel for a bunch of updates regarding Firestore in the near future.
To get started, the first thing you'll need is a Firebase account, and make sure you have the Google login provider enabled.
I'm also assuming that you have an existing Angular project with AngularFire installed.
If not, go to the AngularFire docs and follow the setup instructions for version 5.
The first thing I'm going to do is create a core module, which is used in Angular to handle global services within your app such as authentication.
The core module is technically optional, but it is considered a good practice.
Once you have it generated, add it to the import section of the app module.
Then we can jump over to the core module, and we'll add AngularFire auth and AngularFirestore.
I also have an auth service in here which we're going to generate in the next step.
The auth service is going to handle most of the heavy lifting.
When you generate it, make sure to use the m flag so it gets added to the core module automatically.
Inside of our service, we're going to import the Angular router as well as the AngularFire auth and Firestore services.
We're also gonna use the RxJS observable class and the switch map operator as you'll see here in just a second.
The nice thing about our service is we can define an interface with any custom data that we wanna add to it.
So here I'm going to add a user interface, and I'll just add a few default values here that come with the normal Firebase auth state.
And then I'll also add a custom attribute for favorite color, but you could add anything you want here.
Then the next thing we'll do is set a variable on the service that is typed to this user interface.
From there, we can add our dependencies to the constructor, which is auth, Firestore, and the router.
Then we want to define the user observable inside the structures, so any component can subscribe to it and be updated with new data in real time.
So first, we need the data from the default auth state from Firebase.
So we can get that by calling switch map.
That will give us the user credential which can be either the user data or null.
So if it is defined, then we'll go ahead and and return that data that we save in the Firestore database.
So we can do that by pointing AngularFirestore to the user document that is in the user's collection and has an ID equal to their user ID, and then we call value changes on it to get the observable.
And just so this makes a little more sense, let's look at how we have the database structured.
We have a root users collection, and then each document in that collection has an ID equal to the Firebase auth user ID.
This allows you to add custom data to your users and also query them using the Firestore query methods.
So switching back to the service, Now we just wanna return an observable of null if that user object is not defined.
So the end result here is we're using data from Firestore instead of the data returned from on Firebase Auth.
So the next thing we'll do here is create a method for the user to log in with Google.
And I'm gonna set this up in a way so you can easily reuse the code if you wanna multiple methods such as Twitter, GitHub, or Facebook.
We can do that by passing the provider to this OAuth login method, and that will call the sign in with pop up and return a promise.
But we also need to save the user's initial data in the database, so we'll set up a separate method for that as well.
And we only wanna call that once the user has successfully authenticated through Firebase.
So once the user has authenticated, we're going to have a user ID.
We can use that user ID to make a reference to the Firestore users collection and then a document under that user ID.
From there, I'm just going to transfer some data from the normal Firebase auth to Firestore, but this is where you have the option to set custom data if you want to.
You could even delay this process and have the user fill out a secondary form where they enter required additional fields to their user account.
To save the data, we just need to call user ref, set data, and we're good to go.
The service is ready to authenticate users.
We just need a component to make this possible on the front end.
I'm going to generate a component called user profile, and then we'll just need to inject the auth service into this component.
Make sure that it's public when you add it to the constructor so you can use it in the HTML.
We want to display different HTML based on whether or not the user is authenticated.
We can figure that out by using n g f with the user variable from our auth service and the async pipe.
If the user's authenticated, it emits their data from Firestore, but if not, it just emits null.
From there, we're going to set up 2 different templates based on the authenticated state.
The first one will call authenticated, the other one will call guest.
Based on that state it will replace this div with the templates that we defined below.
We can set those templates with ng template and then a hashtag followed by that template variable name.
In the guest template, I'll just show that the user's a guest and then I'll add a button that will trigger the Google login method from our service when clicked.
Inside the authenticated template, I'm just going to set the user as a template variable so we can use that data from the observable.
So we do that by calling auth user async and then as user which represents the template variable.
So then we can call user display name or user photo URL, or any other custom data that you have in Firestore.
So now let's go see this in action.
We click the connect to Google button here and that should bring up an OAuth window.
And then once we're authenticated, we'll see that our data is updated in Firestore.
Currently, I don't have the favorite color property set, but we'll go ahead and set that in Firestore and you'll see it has a real time connection with the user interface.
As soon as we click add, you'll see that the favorite color gets updated here on the left side on the user interface.
If we click log out, You can see the user session ends, but we still have that data here persisted in Firestore.
So that's very useful if you query public user profiles that get shown throughout your app.
So that's pretty cool, but there's just one more piece of information I wanna show you to round out your auth service.
And that's how to create a router guard to protect routes from unauthorized users.
So first, we'll generate the guard with the Angular CLI.
Inside the guard, we're going to import an RxJS observable class and the auth service that we just created and also a few other RxJS Operators.
From there we'll add the auth service to the constructor of the guard and we can just call the user observable that we had created in the auth service.
We can call take 1 to prevent any long running subscriptions, and then we'll map the user object down to a boolean.
So if the user's logged in, that should return true, and if not, it'll return false.
If it returns true, then the guard will pass and they'll be able to access the route.
But if false, it will console log access denied and then we'll have the router navigate them back to the login page.
So you can add this guard to the can activate array in any of your routes, and then if you try to access one of those routes not being logged in, you'll get access denied message here in the console.
But if we go ahead and log in, then you can see we have full access to the routes, and everything works as expected.
That's it for Firebase OAuth with Firestore.

But if we go ahead and log in, then you can see we have full access to the routes, and everything works as expected. That's it for Firebase OAuth with Firestore.

is
is

Then
then
we
we
can
can
jump
jump
over
over
to
to
the
the
core
core

and
and
we'll
we'll
add
add
AngularFire

and
and
AngularFirestore.
angularfirestore
I
i
also
also
have
have
an
an
auth

in
in
here
here
which
which
we're
we're
going
going
to
to

in
the
the
next

The
the

is
is
going
going

you
you

automatically
Inside
inside
of
of
our
our
service,
service
we're
we're
going
going
to
to
import
import
the
the
Angular
angular
router
router
as
as
well
well
as
as
the
the
AngularFire
angularfire
auth
auth
and
and
Firestore
firestore
services.
services
We're
we're
also
also
gonna
gonna
use
use
the
the
RxJS
rxjs
observable
observable
class
class
and
and
the
the
switch
switch
map
map
operator
operator
as
as
you'll
you'll
see
see
here
here
in
in
just
just
a
a
second.
second
The
the
nice
nice
thing
thing
about
about
our
our
service
service
is
is
we
we
can
can
define
define
an
an
interface
interface
with
with
any
any
custom
custom
data
data
that
that
we
we
wanna
wanna
add
add
to
to
it.
it
So
so
here
here
I'm
i'm
going
going
to
to
add
add
a
a
user
user
interface,
interface
and
and
I'll
i'll
just
just
add
add
a
a
few
few
default
default
values
values
here
here
that
that
come
come
with
with
the
the
normal
normal
Firebase
firebase
auth
auth
state.
state
And
and
then
then
I'll
i'll
also
also
add
add
a
a
custom
custom
attribute
attribute
for
for
favorite
favorite
color,
color
but
but
you
you
could
could
add
add
anything
anything
you
you
want
want
here.
here
Then
then
the
the
next
next
thing
thing
we'll
we'll
do
do
is
is
set
set
a
a
variable
variable
on
on
the
the
service
service
that
that
is
is
typed
typed
to
to
this
this
user
user
interface.
interface
From
from
there,
there
we
we
can
can
add
add
our
our
dependencies
dependencies
to
to
the
the
constructor,
constructor
which
which
is
is
auth,
auth
Firestore,
firestore
and
and
the
the
router.
router
Then
then
we
we
want
want
to
to
define
define
the
the
user
user
observable
observable
inside
inside
the
the
structures,
structures
so
so
any
any
component
component
can
can
subscribe
subscribe
to
to
it
it
and
and
be
be
updated
updated
with
with
new
new
data
data
in
in
real
real
time.
time
So
so
first,
first
we
we
need
need
the
the
data
data
from
from
the
the
default
default
auth
auth
state
state
from
from
Firebase.
firebase
So
so
we
we
can
can
get
get
that
that
by
by
calling
calling
switch
switch
map.
map
That
that
will
will
give
give
us
us
the
the
user
user
credential
credential
which
which
can
can
be
be
either
either
the
the
user
user
data
data
or
or
null.
null
So
so
if
if
it
it
is
is
defined,
defined
then
then
we'll
we'll
go
go
ahead
ahead
and
and
and
and
return
return
that
that
data
data
that
that
we
we
save
save
in
in
the
the
Firestore
firestore
database.
database
So
so
we
we
can
can
do
do
that
that
by
by
pointing
pointing
AngularFirestore
angularfirestore
to
to
the
the
user
user
document
document
that
that
is
is
in
in
the
the
user's
user's
collection
collection
and
and
has
has
an
an
ID
id
equal
equal
to
to
their
their
user
user
ID,
id
and
and
then
then
we
we
call
call
value
value
changes
changes
on
on
it
it
to
to
get
get
the
the
observable.
observable
And
and
just
just
so
so
this
this
makes
makes
a
a
little
little
more
more
sense,
sense
let's
let's
look
look
at
at
how
how
we
we
have
have
the
the
database
database
structured.
structured
We
we
have
have
a
a
root
root
users
users
collection,
collection
and
and
then
then
each
each
document
document
in
in
that
that
collection
collection
has
has
an
an
ID
id
equal
equal
to
to
the
the
Firebase
firebase
auth
auth
user
user
ID.
id
This
this
allows
allows
you
you
to
to
add
add
custom
custom
data
data
to
to
your
your
users
users
and
and
also
also
query
query
them
them
using
using
the
the
Firestore
firestore
query
query
methods.
methods
So
so
switching
switching
back
back
to
to
the
the
service,
service
Now
now
we
we
just
just
wanna
wanna
return
return
an
an
observable
observable
of
of
null
null
if
if
that
that
user
user
object
object
is
is
not
not
defined.
defined
So
so
the
the
end
end
result
result
here
here
is
is
we're
we're
using
using
data
data
from
from
Firestore
firestore
instead
instead
of
of
the
the
data
data
returned
returned
from
from
on
on
Firebase
firebase
Auth.
auth
So
so
the
the
next
next
thing
thing
we'll
we'll
do
do
here
here
is
is
create
create
a
a
method
method
for
for
the
the
user
user
to
to
log
log
in
in
with
with
Google.
google
And
and
I'm
i'm
gonna
gonna
set
set
this
this
up
up
in
in
a
a
way
way
so
so
you
you
can
can
easily
easily
reuse
reuse
the
the
code
code
if
if
you
you
wanna
wanna
multiple
multiple
methods
methods
such
such
as
as
Twitter,
twitter
GitHub,
github
or
or
Facebook.
facebook
We
we
can
can
do
do
that
that
by
by
passing
passing
the
the
provider
provider
to
to
this
this
OAuth
oauth
login
login
method,
method
and
and
that
that
will
will
call
call
the
the
sign
sign
in
in
with
with
pop
pop
up
up
and
and
return
return
a
a
promise.
promise
But
but
we
we
also
also
need
need
to
to
save
save
the
the
user's
user's
initial
initial
data
data
in
in
the
the
database,
database
so
so
we'll
we'll
set
set
up
up
a
a
separate
separate
method
method
for
for
that
that
as
as
well.
well
And
and
we
we
only
only
wanna
wanna
call
call
that
that
once
once
the
the
user
user
has
has
successfully
successfully
authenticated
authenticated
through
through
Firebase.
firebase
So
so
once
once
the
the
user
user
has
has
authenticated,
authenticated
we're
we're
going
going
to
to
have
have
a
a
user
user
ID.
id
We
we
can
can
use
use
that
that
user
user
ID
id
to
to
make
make
a
a
reference
reference
to
to
the
the
Firestore
firestore
users
users
collection
collection
and
and
then
then
a
a
document
document
under
under
that
that
user
user
ID.
id
From
from
there,
there
I'm
i'm
just
just
going
going
to
to
transfer
transfer
some
some
data
data
from
from
the
the
normal

Firebase
firebase

to
to
Firestore,

but
but
this
this
is
is
where
where
you
you
have
have
the
the
option

to
to
set

so
so
we
we
can
can
use
use
that
that

So
so
we
we
do
do
that
that
by
by
calling
calling

and
then
then
as

So
so
then
then
we
we
can

So
so
now
now
let's
let's
go

We
we
click
click
the

here
here
and
and
that
that
should
should
bring
bring

And
and
then
then
once
once
we're
we're

we'll
see
see
that
that
our
our

I
i
don't
don't

but
but
we'll
we'll
go
go

and
and
set

that
that
in
in
Firestore

and
and
you'll
you'll

The speakers discuss implementing a custom data implementation in Angular, creating a denies account and router guard, and setting a variable for a user interface. They also explain how to set up a user profile and create a new one, and how to use the face ID in the Foveract service to authenticate users and change the default authenticator. They also show how to set up a router guard and access routes not logged in, and offer a free book and a project consulting link.
