An easy way to make your app more polished is to implement animations between router transitions.
Today's video is a complete guide to router animations in Angular and we'll build 4 different styles that range from a simple Fade into a complex key frame sequence of animations.
If you're new here, like and subscribe, and grab the full source code from Fireship IO.
And before we get started, I wanna give a Shout out to the DealCrunch app, which is a real estate app available on iOS and Android.
It was built by one of our pro members and is a great example of what you can do with Angular and Now, let's first start by looking at the actual animations that we'll build in this video.
The first one is just a simple fade in, which is applied to every single route in the app.
The second animation is a Slide from left to right, and it determines which direction to slide based on data that we pass in through the router configuration.
The third one is slightly more Plex and adds in transformations so we can make the page kind of rotate in from the top corners.
And the 4th and final one uses keyframes to create a sequence of style changes.
For example, the new page comes in from the bottom and bumps the old page off and it spins and scales out of the screen.
I'm starting off here in my Angular 7 app, And you'll notice that I've generated a handful of components here just so we have something to actually route to.
And you don't need to do anything special with these components whatsoever, so we won't even bother looking at them in this video.
Then the other thing we'll do in the app module is import the browser animations module and add it to the imports array.
From there, we'll go into the HTML on the app component and create a main element and then define an animation called route animations.
And then we'll point this to a method called prepare route which we'll define in a second and its job is to determine which animation to apply to a given route.
Now, inside of this element, we'll define our router outlet and then give it a template variable name of outlet as well.
Now, whenever a route changes, we can animate the content inside of the router outlet.
Then you can see above the Outlet, I have my actual navigation bar, so this will stay fixed and not be animated between the route changes.
Now we'll jump into the App Component typescript you'll see that I'm importing these animations which we have not yet defined.
I simply wanna point out that we'll be adding these to the animation property in the component decorator and you can just uncomment whichever animation that you wanna use here.
In our case, we're going to be defining different animations for different routes, so we need to create this prepareRoute method to pass in that dynamic Data.
This is actually taken directly from the Angular docs and it's technically optional if you're only using a single animation for every route.
In that case you could pass the Outlet to the animation directly in the gml.
The last thing we wanna do is go into our router configuration and you'll see we have 3 routes set up each one just pointing to a component.
When we get to our Slide reanimation will need to determine if a component should slide in from the left or slide in from the right.
We can do this by passing in a data attribute and we'll give it a name of animation.
Then we'll define animations named isRight and isLeft.
Now that prepareRoute method that we defined earlier will look for this property and then apply the corresponding animation.
The next thing I'm going to do is create a file called route animations dot ts in the App Directory and then we'll basically import everything under the kitchen sink from Angular animations.
The first animation we'll build is the most basic use case, which is just a standard animation that gets applied to every route change.
Notice we give the trigger a name of route animations That must match what you entered in the HTML.
The next thing we'll do is define a transition, which determines how to apply styles from one animation to the next.
In this case, we're using the star arrow syntax to define a wildcard that will apply to every single route transition.
Angular animations will apply 2 pseudo selectors to the elements We're animating, one called enter and one called leave.
So enter is the new page, leave is the old page.
And query allows us to actually select these elements from the DOM.
So the first step in the transition is to prepare these elements so they can be animated.
To do that effectively, we'll position them as absolute And then we'll also bring the opacity down to 0 and then translate them off the screen and scale them down to 0.
So basically with this step we're just creating a starting point from which we can use is to animate in the new page.
And at the same time, we're immediately hiding the old page.
So Angular animations will apply these steps in the transition one after the other.
So at this point we've styled our elements both to be hidden.
Now we need to animate in the new page.
We can do that by making a query for the enter selector which again is the new page And then we'll animate that in.
But first I wanna point out that I had to go into the style CSS and set the main element to position relative.
This just ensures that you have a consistent Style between the page transitions.
Now back to our animation we've queried for the enter selector then we'll use the animate method to set up the actual transition.
We'll give it a timing of 600 milliseconds with the Ease function.
Then we'll define a style that is basically the end point of the animation.
So from our starting point we'll wanna set the Opacity to 1, scale it to 1 and then set the y axis translation to 0.
So just to recap the entire animation, we start by hiding both the old and new components, then we fade in the new component over the course of 600 milliseconds.
The end result looks like this and the same animation is applied to every route change.
But you'll notice our layout has both a right page and a left page, so there's sort of a concept of position within this layout.
In the next animation, we'll actually take into account the position and do a different animation based on whether or not the component is on the right or the left.
Now I'm defining a function called slide 2 which will allow us to reuse a lot of the same logic for both the left and right transitions.
This animation has multiple transition possibilities and that's based on the dynamic data that we're passing in through the router config.
So any component that transitions to the is left animation will slide to the left.
And conversely, any component going to the right will slide to the right.
Then our middle component doesn't have any animation data defined at all.
So we'll also wanna set up transitions any time that we're going from the is right animation just to any component.
That means that we should be moving to the left, so we'll go ahead and use the slide to the left animation.
And lastly, we'll do the same thing for the opposite.
And now we'll define the actual slide two function.
I'm setting up a variable for optional here because some of these queries will want to be in case the actual leaving component isn't present.
Then just like we did before we'll set up some default styles here.
In this case, we don't wanna actually hide the elements, but we'll just make them positioned salute and at the top of the page.
And then we'll dynamically pass in the direction which can either be right or left.
So those styles are applied to both components, But we want to add an additional style to only the entering component which will offset it in either direction 100% from its sibling component.
At this point we have 2 different components that we want to animate and we want those to happen at the same time which is why we add them to a group otherwise they would happen one after the other.
We can start with the animation for the Leaving component.
In this case, we'll go ahead and animate it 100% off the screen.
So that will move it in the The direction of the starting point from the Entering Component.
Then to animate the Entering Component we'll just go ahead and set its direction to 0% which will put it right in the middle where it's supposed to be.
And you'll also notice that both of the animations have the same timing function.
And the end result is just a smooth sliding animation from left to right.
But Let's go ahead and move on to transition number 3 which is just a variation on this last one but instead uses CSS transforms.
This allows us to achieve that same sliding effect, but we can also do cool things like rotation or scaling or whatever else we wanna add in here.
We'll start with the same basic setup as last time And we'll define triggers that go from left to right.
But this time, you'll notice we're passing in a bunch of named arguments.
So our function will take an x value, a y value, and also a Rotation value.
So my goal here is basically to give you a function that you can configure with your own arguments to create a whole bunch of different crazy animations.
Now Now if we go down to the actual function you can see that I'm using destructuring to add named arguments to this function with default values.
That's just some useful syntactic sugar If you have a single object as an argument that has default values.
Again, we'll start this animation off by styling the enter and leave components.
Then we can define our transformations by simply interpolating values into Strings.
For example, we can add x and y values to translate as percentages And then a rotation value as degrees for rotate.
And you could even extend this with skew and scale or whatever other transformations you wanna use.
Now if we skip ahead here to the animations, they're pretty much identical to the previous example except we're adding the values in here for the transforms instead of the direction.
Now we're going to switch gears and look at a keyframed animation.
Currently, all of our animations use a transition which basically just has a single starting point and ending point.
But in many cases with animations, you have multiple intermediate steps that can't be defined by just a single start and end point.
So let's go ahead and define a new animation that just uses the wildcard to apply the same animation to every route.
Then like every other animation, we'll set the initial position to absolute.
Then we'll also set up a group to run the 2 page animations concurrently.
Then in all the previous examples, we just animated to a single Style.
In this example, we'll use the keyframes function to pass in an array of styles.
You can think of these styles as steps in your animation And you determine where they happen based on the total time by setting an offset value.
So an offset of 0 will apply the style as soon as the animation starts.
We're working with the Entry component we'll go ahead and scale it to 0 and translate it off the page.
Then we'll add a second style with an offset of 0.3 which for a 2 1000 millisecond animation would be 600 milliseconds.
In other words, this style will be applied to the element at 30% of its animation lifecycle.
And we'll finish things up by setting a final style with an offset of 1 which is the end of the animation.
And that will be when the component is fully visible at a scale of 1 and a translate of 0.
Now we'll go down here to the Leave component and try to roughly match the keyframes to the Entering component.
We want to achieve an effect that makes it look like the Entering component bumps The old component off the screen.
We can achieve that by scaling it up to 600% of its original size while at the same time rotating it and fading it out to an opacity of 0.
The end result is this 3 d effect of the pages looking like they're colliding.
Hopefully, this video gave you an idea of what is possible with Angular router animations so you can start building your own beautiful transitions between Pages in your app.
I'm gonna go ahead and wrap things up there.

animation
That's just some useful syntactic sugar If you have a single object as an argument that has default values. Again, we'll start this animation off by styling the enter and leave components. Then we can define our transformations by simply interpolating values into Strings. For example, we can add x and y values to translate as percentages And then a rotation value as degrees for rotate.

And you could even extend this with skew and scale or whatever other transformations you wanna use. Now if we skip ahead here to the animations, they're pretty much identical to the previous example except we're adding the values in here for the transforms instead of the direction. Now we're going to switch gears and look at a keyframed animation. Currently, all of our animations use a transition which basically just has a single starting point and ending point. But in many cases with animations, you have multiple intermediate steps that can't be defined by just a single start and end point. So let's go ahead and define a new animation that just uses the wildcard to apply the same animation to every route. Then like every other animation, we'll set the initial position to absolute. Then we'll also set up a group to run the 2 page animations concurrently. Then in all the previous examples, we just animated to a single Style. In this example, we'll use the keyframes function to pass in an array of styles. You can think of these styles as steps in your animation And you determine where they happen based on the total time by setting an offset value. So an offset of 0 will apply the style as soon as the animation starts. We're working with the Entry component we'll go ahead and scale it to 0 and translate it off the page. Then we'll add a second style with an offset of 0.3 which for a 2 1000 millisecond animation would be 600 milliseconds. In other words, this style will be applied to the element at 30% of its animation lifecycle. And we'll finish things up by setting a final style with an offset of 1 which is the end of the animation. And that will be when the component is fully visible at a scale of 1 and a translate of 0. Now we'll go down here to the Leave component and try to roughly match the keyframes to the Entering component.

We want to achieve an effect that makes it look like the Entering component bumps The old component off the screen.
We can achieve that by scaling it up to 600% of its original size while at the same time rotating it and fading it out to an opacity of 0. The end result is this 3 d effect of the pages looking like they're colliding.

An easy way to make your app more polished is to implement animations between router transitions. Today's video is a complete guide to router animations in Angular and we'll build 4 different styles that range from a simple Fade into a complex key frame sequence of animations. If you're new here, like and subscribe, and grab the full source code from Fireship IO. And before we get started, I wanna give a Shout out to the DealCrunch app, which is a real estate app available on iOS and Android. It was built by one of our pro members and is a great example of what you can do with Angular and Now, let's first start by looking at the actual animations that we'll build in this video. The first one is just a simple fade in, which is applied to every single route in the app. The second animation is a Slide from left to right, and it determines which direction to slide based on data that we pass in through the router configuration. The third one is slightly more Plex and adds in transformations so we can make the page kind of rotate in from the top corners. And the 4th and final one uses keyframes to create a sequence of style changes. For example, the new page comes in from the bottom and bumps the old page off and it spins and scales out of the screen. I'm starting off here in my Angular 7 app, And you'll notice that I've generated a handful of components here just so we have something to actually route to. And you don't need to do anything special with these components whatsoever, so we won't even bother looking at them in this video. Then the other thing we'll do in the app module is import the browser animations module and add it to the imports array. From there, we'll go into the HTML on the app component and create a main element and then define an animation called route animations. And then we'll point this to a method called prepare route which we'll define in a second and its job is to determine which animation to apply to a given route. Now, inside of this element, we'll define our router outlet and then give it a template variable name of outlet as well. Now, whenever a route changes, we can animate the content inside of the router outlet. Then you can see above the Outlet, I have my actual navigation bar, so this will stay fixed and not be animated between the route changes. Now we'll jump into the App Component typescript you'll see that I'm importing these animations which we have not yet defined. I simply wanna point out that we'll be adding these to the animation property in the component decorator and you can just uncomment whichever animation that you wanna use here. In our case, we're going to be defining different animations for different routes, so we need to create this prepareRoute method to pass in that dynamic Data. This is actually taken directly from the Angular docs and it's technically optional if you're only using a single animation for every route. In that case you could pass the Outlet to the animation directly in the gml. The last thing we wanna do is go into our router configuration and you'll see we have 3 routes set up each one just pointing to a component. When we get to our Slide reanimation will need to determine if a component should slide in from the left or slide in from the right. We can do this by passing in a data attribute and we'll give it a name of animation. Then we'll define animations named isRight and isLeft. Now that prepareRoute method that we defined earlier will look for this property and then apply the corresponding animation. The next thing I'm going to do is create a file called route animations dot ts in the App Directory and then we'll basically import everything under the kitchen sink from Angular animations. The first animation we'll build is the most basic use case, which is just a standard animation that gets applied to every route change. Notice we give the trigger a name of route animations That must match what you entered in the HTML. The next thing we'll do is define a transition, which determines how to apply styles from one animation to the next. In this case, we're using the star arrow syntax to define a wildcard that will apply to every single route transition. Angular animations will apply 2 pseudo selectors to the elements We're animating, one called enter and one called leave. So enter is the new page, leave is the old page. And query allows us to actually select these elements from the DOM. So the first step in the transition is to prepare these elements so they can be animated. To do that effectively, we'll position them as absolute And then we'll also bring the opacity down to 0 and then translate them off the screen and scale them down to 0. So basically with this step we're just creating a starting point from which we can use is to animate in the new page. And at the same time, we're immediately hiding the old page. So Angular animations will apply these steps in the transition one after the other. So at this point we've styled our elements both to be hidden. Now we need to animate in the new page. We can do that by making a query for the enter selector which again is the new page And then we'll animate that in. But first I wanna point out that I had to go into the style CSS and set the main element to position relative. This just ensures that you have a consistent Style between the page transitions. Now back to our animation we've queried for the enter selector then we'll use the animate method to set up the actual transition. We'll give it a timing of 600 milliseconds with the Ease function. Then we'll define a style that is basically the end point of the animation. So from our starting point we'll wanna set the Opacity to 1, scale it to 1 and then set the y axis translation to 0. So just to recap the entire animation, we start by hiding both the old and new components, then we fade in the new component over the course of 600 milliseconds. The end result looks like this and the same animation is applied to every route change. But you'll notice our layout has both a right page and a left page, so there's sort of a concept of position within this layout. In the next animation, we'll actually take into account the position and do a different animation based on whether or not the component is on the right or the left. Now I'm defining a function called slide 2 which will allow us to reuse a lot of the same logic for both the left and right transitions. This animation has multiple transition possibilities and that's based on the dynamic data that we're passing in through the router config. So any component that transitions to the is left animation will slide to the left. And conversely, any component going to the right will slide to the right. Then our middle component doesn't have any animation data defined at all. So we'll also wanna set up transitions any time that we're going from the is right animation just to any component. That means that we should be moving to the left, so we'll go ahead and use the slide to the left animation. And lastly, we'll do the same thing for the opposite. And now we'll define the actual slide two function. I'm setting up a variable for optional here because some of these queries will want to be in case the actual leaving component isn't present. Then just like we did before we'll set up some default styles here. In this case, we don't wanna actually hide the elements, but we'll just make them positioned salute and at the top of the page. And then we'll dynamically pass in the direction which can either be right or left. So those styles are applied to both components, But we want to add an additional style to only the entering component which will offset it in either direction 100% from its sibling component. At this point we have 2 different components that we want to animate and we want those to happen at the same time which is why we add them to a group otherwise they would happen one after the other. We can start with the animation for the Leaving component. In this case, we'll go ahead and animate it 100% off the screen. So that will move it in the The direction of the starting point from the Entering Component. Then to animate the Entering Component we'll just go ahead and set its direction to 0% which will put it right in the middle where it's supposed to be. And you'll also notice that both of the animations have the same timing function. And the end result is just a smooth sliding animation from left to right. But Let's go ahead and move on to transition number 3 which is just a variation on this last one but instead uses CSS transforms. This allows us to achieve that same sliding effect, but we can also do cool things like rotation or scaling or whatever else we wanna add in here. We'll start with the same basic setup as last time And we'll define triggers that go from left to right. But this time, you'll notice we're passing in a bunch of named arguments. So our function will take an x value, a y value, and also a Rotation value. So my goal here is basically to give you a function that you can configure with your own arguments to create a whole bunch of different crazy animations. Now Now if we go down to the actual function you can see that I'm using destructuring to add named arguments to this function with default values. That's just some useful syntactic sugar If you have a single object as an argument that has default values. Again, we'll start this animation off by styling the enter and leave components. Then we can define our transformations by simply interpolating values into Strings. For example, we can add x and y values to translate as percentages And then a rotation value as degrees for rotate. And you could even extend this with skew and scale or whatever other transformations you wanna use. Now if we skip ahead here to the animations, they're pretty much identical to the previous example except we're adding the values in here for the transforms instead of the direction. Now we're going to switch gears and look at a keyframed animation. Currently, all of our animations use a transition which basically just has a single starting point and ending point. But in many cases with animations, you have multiple intermediate steps that can't be defined by just a single start and end point.

we'll
do
do
is
is
define
define
a
a
transition,
transition
which
which
determines
determines
how
how
to
to
apply
apply
styles
styles
from
from
one
one
animation
animation
to
to
the
the
next.
next
In
in
this
this
case,
case
we're
we're
using
using
the
the
star
star
arrow
arrow
syntax
syntax
to
to
define
define
a
a
wildcard
wildcard
that
that
will
will
apply
apply
to
to
every
every
single
single
route
route
transition.
transition
Angular
angular
animations
animations
will
will
apply
apply
2
2
pseudo
pseudo
selectors
selectors
to
to
the
the
elements
elements
We're
we're
animating,
animating
one
one
called
called
enter
enter
and
and
one
one
called
called
leave.
leave
So
so
enter
enter
is
is
the
the
new
new
page,
page
leave
leave
is
is
the
the
old
old
page.
page
And
and
query
query
allows
allows
us
us
to
to
actually
actually
select
select
these
these
elements
elements
from
from
the
the
DOM.
dom
So
so
the
the
first
first
step
step
in
in
the
the
transition
transition
is
is
to
to
prepare
prepare
these
these
elements
elements
so
so
they
they
can
can
be
be
animated.
animated
To
to
do
do
that
that
effectively,
effectively
we'll
we'll
position
position
them
them
as
as
absolute
absolute
And
and
then
then
we'll
we'll
also
also
bring
bring
the
the
opacity
opacity
down
down
to
to
0
0
and
and
then
then
translate
translate
them
them
off
off
the
the
screen
screen
and
and
scale
scale
them
them
down
down
to
to
0.
0
So
so
basically
basically
with
with
this
this
step
step
we're
we're
just
just
creating
creating
a
a
starting
starting
point
point
from
from
which
which
we
we
can
can
use
use
is
is
to
to
animate
animate
in
in
the
the
new
new
page.
page
And
and
at
at
the
the
same
same
time,
time
we're
we're
immediately
immediately
hiding
hiding
the
the
old
old
page.
page
So
so
Angular
angular
animations
animations
will
will
apply
apply
these
these
steps
steps
in
in
the
the
transition
transition
one
one
after
after
the
the
other.
other
So
so
at
at
this
this
point
point
we've
we've
styled
styled
our
our
elements
elements
both
both
to
to
be
be
hidden.
hidden
Now
now
we
we
need
need
to
to
animate
animate
in
in
the
the
new
new
page.
page
We
we
can
can
do
do
that
that
by
by
making
making
a
a
query
query
for
for
the
the
enter
enter
selector
selector
which
which
again
again
is
is
the
the
new
new
page
page
And
and
then
then
we'll
we'll
animate
animate
that
that
in.
in
But
but
first
first
I
i
wanna
wanna
point
point
out
out
that
that
I
i
had
had
to
to
go
go
into
into
the
the
style
style
CSS
css
and
and
set
set
the
the
main
main
element
element
to
to
position
position
relative.
relative
This
this
just
just
ensures
ensures
that
that
you
you
have
have
a
a
consistent
consistent
Style
style
between
between
the
the
page
page
transitions.
transitions
Now
now
back
back
to
to
our
our
animation
animation
we've
we've
queried
queried
for
for
the
the
enter
enter
selector
selector
then
then
we'll
we'll
use
use
the
the
animate
animate
method
method
to
to
set
set
up
up
the
the
actual
actual
transition.
transition
We'll
we'll
give
give
it
it
a
a
timing
timing
of
of
600
600
milliseconds
milliseconds
with
with
the
the
Ease
ease
function.
function
Then
then
we'll
we'll
define
define
a
a
style
style
that
that
is
is
basically
basically
the
the
end
end
point
point
of
of
the
the
animation.
animation
So
so
from
from
our
our
starting
starting
point
point
we'll
we'll
wanna
wanna
set
set
the
the
Opacity
opacity
to
to
1,
1
scale
scale
it
it
to
to
1
1
and
and
then
then
set
set
the
the
y
y
axis
axis
translation
translation
to
to
0.
0
So
so
just
just
to
to
recap
recap
the
the
entire
entire
animation,
animation
we
we
start
start
by
by
hiding
hiding
both
both
the
the
old
old
and
and
new
new
components,
components
then
then
we
we
fade
fade
in
in
the
the
new
new
component
component
over
over
the
the
course
course
of
of
600
600
milliseconds.
milliseconds
The
the
end
end
result
result
looks
looks
like
like
this
this
and
and
the
the
same
same
animation
animation
is
is
applied
applied
to
to
every
every
route
route
change.
change
But
but
you'll
you'll
notice
notice
our
our
layout
layout
has
has
both
both
a
a
right
right
page
page
and
and
a
a
left
left
page,
page
so
so
there's
there's
sort
sort
of
of
a
a
concept
concept
of
of
position
position
within
within
this
this
layout.
layout
In
in
the
the
next
next
animation,
animation
we'll
we'll
actually
actually
take
take
into
into
account
account
the
the
position
position
and
and
do
do
a
a
different
different
animation
animation
based
based
on
on
whether
whether
or
or
not
not
the
the
component
component
is
is
on
on
the
the
right
right
or
or
the
the
left.
left
Now
now
I'm
i'm
defining
defining
a
a
function
function
called
called
slide
slide
2

which
which
will
will
allow
allow
us
us
to
to
reuse
reuse
a
a
lot
lot
of
of
the
the
same
same
logic
logic
for
for
both
both
the
the
left
left
and
and
right
right
transitions.
transitions
This
this
animation
animation
has
has
multiple
multiple
transition
transition
possibilities
possibilities
and
and
that's
that's
based
based
on
on
the
the
dynamic
dynamic
data
data
that
that
we're
we're
passing
passing
in
in
through
through
the
the

config
So
so
any
any
component
component
that
that
transitions
transitions
to
to
the
the
is
is
left
left
animation
animation
will
will
slide
slide
to
to
the
the

left
And
and
conversely,
conversely
any
any
component
component
going
going
to
to
the
the
right
right
will
will
slide
slide
to
to
the
the
right.
right
Then
then
our
our
middle
middle
component
component
doesn't
doesn't
have
have
any
any
animation
animation
data
data
defined
defined
at
at
all.
all
So
so
we'll
we'll
also
also
wanna
wanna
set
set
up
up
transitions
transitions
any
any
time
time
that
that
we're
we're
going
going
from
from
the
the

is
right

just
just
to
to
any
any
component.

That
that
means
means
that
that
we
we
should
should
be
be
moving
moving
to
to
the
the
left,
left
so
so
we'll
we'll
go
go
ahead
ahead
and
and
use
use
the
the
slide
slide
to
to
the
the
left
left
animation.
animation
And
and
lastly,
lastly
we'll
we'll
do
do
the
the
same
same
thing
thing
for
for
the
the
opposite.

And
and
now
now
we'll
we'll
define
define
the
the
actual
actual

I'm
i'm
setting

up
up
a
a

because
because
some
some
of
of
these
these

will
will
want

the

Then
then
just
just
like
like
we
we
did
did
before
before
we'll
we'll
set
set
up
up
some
some
default
default
styles

here.
here
In
in
this
this
case,
case
we
we
don't
don't
wanna
wanna
actually
actually
hide
hide
the
the
elements,
elements
but
but
we'll
we'll
just
just
make
make
them
them
positioned

and
and
at
at
the
the

And
and
then
then
we'll
we'll
dynamically

pass

in
the
the

which
can
can
either
either

So
so
those
those
styles

are
are
applied
applied
to
to
both
both

But
but
we
we
want

to
to

At
at

we
we
have
have

In
in

So
so
that
that

And
and
you'll
you'll
also
also
notice

that
that
both

And
and
the

is
is
just
just
a
a

Let's
let's

This
this
allows
allows
us
us
to
to
achieve

that
that

but
but
we
we
can
can
also
also
do

We'll
we'll

And
and
we'll
we'll

right
But
but
this
this
time,
time
you'll
you'll
notice
notice
we're
we're
passing
passing
in
in
a
a

So
so
our
our
function

will
will
take

a
a

and
and
also
also

So
so
my
my
goal
goal
here
here
is
is
basically
basically
to
to
give
give
you
you
a
a

that
that

you
can
can

we
we

That's
that's
just
just
some
some

Again,

we'll
we'll

by

Then
then
we
we

Now
now
if

we
we
skip

they're
they're

Now
now
we're
we're
going
going

Currently,
currently
all
all
of
of
our
our

use

basically
basically
just
just

But
but
in
in
many

with
with

you
you
have
have

So
so
let's
let's
go
go
ahead
ahead
and
and
define
define
a
a
new
new

animation
that
that
just
just
uses

the
the

Then
then
like
like
every

we'll
we'll
set

the
the

Then
then
we'll
we'll
also
also

Then
then
in
in
all
all
the
the
previous
previous
examples,

we
we
just
just
animated

to
to
a
a

In
in
this
this

we'll
we'll

You
you
can

So
so
an

The speaker explains how to use the Angular app to create animations between router transitions, including setting up multiple component transitions, creating a route file, and setting up styles for each one. They provide step-by-step guides for creating a route file, importting information from Angular, and setting up the appropriate animation steps. The importance of creating a dynamic data attribute for each transition is emphasized, along with a keyframes function to rephrase a function and set up styles for each element. Viewers are instructed to like and subscribe to the channel and provide a full source code.
