hey friends this is your host Rodrigo
0:37
hey friends this is your host Rodrigo and today this is session two of daer in
0:41
and today this is session two of daer in
0:41
and today this is session two of daer in action and we're going to talk about the
0:43
action and we're going to talk about the
0:43
action and we're going to talk about the pops up building
0:45
pops up building
0:45
pops up building block and before we do that let me
0:48
block and before we do that let me
0:48
block and before we do that let me explain to you one of the things that
0:51
explain to you one of the things that
0:51
explain to you one of the things that were missing from the other day remember
0:54
were missing from the other day remember
0:54
were missing from the other day remember that we have to install the Dapper CLI
0:58
that we have to install the Dapper CLI
0:58
that we have to install the Dapper CLI right and then you have to initialize
1:01
right and then you have to initialize
1:01
right and then you have to initialize Dapper so you install the Dapper C then
1:05
Dapper so you install the Dapper C then
1:05
Dapper so you install the Dapper C then initialize Dapper there are two ways you
1:08
initialize Dapper there are two ways you
1:08
initialize Dapper there are two ways you can do that so the first one is if you
1:11
can do that so the first one is if you
1:11
can do that so the first one is if you have
1:12
have
1:12
have Docker then you just type dopper in it
1:17
Docker then you just type dopper in it
1:17
Docker then you just type dopper in it and it's going to download the container
1:20
and it's going to download the container
1:20
and it's going to download the container images and it's going to run some
1:23
images and it's going to run some
1:23
images and it's going to run some containers so as you can see here on the
1:25
containers so as you can see here on the
1:25
containers so as you can see here on the screen actually let me do that um let me
1:30
screen actually let me do that um let me
1:30
screen actually let me do that um let me open up my
1:32
open up my
1:32
open up my terminal by using my administrator
1:36
terminal by using my administrator
1:36
terminal by using my administrator permissions
1:39
permissions
1:39
permissions and check this out Dapper in it right so
1:43
and check this out Dapper in it right so
1:43
and check this out Dapper in it right so this is
1:44
this is
1:44
this is detecting that if I use Dapper in it
1:48
detecting that if I use Dapper in it
1:48
detecting that if I use Dapper in it then I should have Docker otherwise I
1:51
then I should have Docker otherwise I
1:51
then I should have Docker otherwise I need to use the Lim option slim is an
1:57
need to use the Lim option slim is an
1:57
need to use the Lim option slim is an option for using Dapper with without
2:00
option for using Dapper with without
2:00
option for using Dapper with without containers which is fantastic for some
2:04
containers which is fantastic for some
2:04
containers which is fantastic for some people when you don't have enough
2:06
people when you don't have enough
2:06
people when you don't have enough computer computing power or you don't
2:09
computer computing power or you don't
2:09
computer computing power or you don't have permissions for using Docker in
2:11
have permissions for using Docker in
2:11
have permissions for using Docker in your computer and so on right and so you
2:16
your computer and so on right and so you
2:16
your computer and so on right and so you have to use daer init
2:18
have to use daer init
2:18
have to use daer init slim and in this case you have to
2:22
slim and in this case you have to
2:22
slim and in this case you have to install everything related to
2:24
install everything related to
2:24
install everything related to Dapper so in other words you have to
2:27
Dapper so in other words you have to
2:27
Dapper so in other words you have to install the concrete implementation of
2:30
install the concrete implementation of
2:30
install the concrete implementation of the build building blocks that you want
2:32
the build building blocks that you want
2:32
the build building blocks that you want to use okay so in this case I want to
2:36
to use okay so in this case I want to
2:36
to use okay so in this case I want to use Docker because I happen to have
2:38
use Docker because I happen to have
2:38
use Docker because I happen to have Docker Docker desktop in this Windows 11
2:42
Docker Docker desktop in this Windows 11
2:42
Docker Docker desktop in this Windows 11 machine and I'm the
2:44
machine and I'm the
2:44
machine and I'm the administrator so everything's good I'm
2:47
administrator so everything's good I'm
2:48
administrator so everything's good I'm gonna execute Dapper in it I'm just
2:51
gonna execute Dapper in it I'm just
2:51
gonna execute Dapper in it I'm just going to wait for Docker to execute now
2:54
going to wait for Docker to execute now
2:54
going to wait for Docker to execute now it's running right and Dapper in it so
2:58
it's running right and Dapper in it so
2:58
it's running right and Dapper in it so you can see that this is going going to
3:00
you can see that this is going going to
3:00
you can see that this is going going to download some container images but
3:03
download some container images but
3:03
download some container images but before I do that you can see that this
3:05
before I do that you can see that this
3:05
before I do that you can see that this this is asking me to
3:07
this is asking me to
3:07
this is asking me to uninstall Dapper okay I'm going to
3:11
uninstall Dapper okay I'm going to
3:11
uninstall Dapper okay I'm going to uninstall
3:13
uninstall
3:13
uninstall Dapper and then Dapper in it finally
3:17
Dapper and then Dapper in it finally
3:17
Dapper and then Dapper in it finally okay so this is going to install dopper
3:21
okay so this is going to install dopper
3:21
okay so this is going to install dopper 1.14 it's going to download the
3:23
1.14 it's going to download the
3:23
1.14 it's going to download the container images it's going to run those
3:25
container images it's going to run those
3:25
container images it's going to run those container images as
3:27
container images as
3:27
container images as containers and so far so good now I have
3:31
containers and so far so good now I have
3:31
containers and so far so good now I have Dapper installed in this machine so you
3:34
Dapper installed in this machine so you
3:34
Dapper installed in this machine so you can see that this particular command
3:38
can see that this particular command
3:38
can see that this particular command creates this do dapper folder inside my
3:41
creates this do dapper folder inside my
3:41
creates this do dapper folder inside my user folder in other words you can go
3:44
user folder in other words you can go
3:44
user folder in other words you can go ahead and go to your user folder in this
3:48
ahead and go to your user folder in this
3:48
ahead and go to your user folder in this case this is mine right and then do
3:51
case this is mine right and then do
3:51
case this is mine right and then do dopper and this is the place where all
3:54
dopper and this is the place where all
3:54
dopper and this is the place where all the binaries are located in your
3:57
the binaries are located in your
3:57
the binaries are located in your computer okay user folder dopper and we
4:02
computer okay user folder dopper and we
4:02
computer okay user folder dopper and we can find some jaml files such as the
4:05
can find some jaml files such as the
4:05
can find some jaml files such as the config jaml file and inside the
4:08
config jaml file and inside the
4:08
config jaml file and inside the components folder we can see a couple of
4:11
components folder we can see a couple of
4:11
components folder we can see a couple of jaml files for configuring the pops up
4:13
jaml files for configuring the pops up
4:13
jaml files for configuring the pops up building block that we're going to see
4:15
building block that we're going to see
4:15
building block that we're going to see today and the state store building block

today and the state store building block
4:18
today and the state store building block that we're going to see in a following
4:21
that we're going to see in a following
4:21
that we're going to see in a following session okay and some other binaries
4:25
session okay and some other binaries
4:25
session okay and some other binaries here in the bin folder such as the
4:28
here in the bin folder such as the
4:28
here in the bin folder such as the Dapper d

Dapper d
4:30
Dapper d XE file which is the
4:33
XE file which is the
4:33
XE file which is the Dapper side car don't be confused okay
4:37
Dapper side car don't be confused okay
4:37
Dapper side car don't be confused okay this is the side car this is not the
4:40
this is the side car this is not the
4:40
this is the side car this is not the same as the one that is installed here
4:42
same as the one that is installed here
4:42
same as the one that is installed here in the Dapper folder when you install
4:44
in the Dapper folder when you install
4:44
in the Dapper folder when you install the Dapper CLI you have the Dapper doxe
4:47
the Dapper CLI you have the Dapper doxe
4:47
the Dapper CLI you have the Dapper doxe file here okay this is the CLI and this
4:50
file here okay this is the CLI and this
4:50
file here okay this is the CLI and this other one is the Dapper sidecar okay
4:54
other one is the Dapper sidecar okay
4:54
other one is the Dapper sidecar okay let's go ahead and navigate to bin and
4:57
let's go ahead and navigate to bin and
4:57
let's go ahead and navigate to bin and dopper side car okay and you can see
4:59
dopper side car okay and you can see
4:59
dopper side car okay and you can see that I have this other executable which
5:02
that I have this other executable which
5:02
that I have this other executable which which is the
5:03
which is the
5:03
which is the dashboard and this is for using the

for your Docker uh desktop instance and watch those containers running in your
5:47
watch those containers running in your
5:47
watch those containers running in your machine this is
5:50
machine this is
5:50
machine this is marvelous fantastic
5:53
marvelous fantastic
5:53
marvelous fantastic now if you happen to have
5:56
now if you happen to have
5:56
now if you happen to have kubernetes uh you can use the dash k
6:00
kubernetes uh you can use the dash k
6:00
kubernetes uh you can use the dash k uh flag I'm going to show you that in a
6:03
uh flag I'm going to show you that in a
6:03
uh flag I'm going to show you that in a following session when we talk about
6:05
following session when we talk about
6:05
following session when we talk about deployment just realize that there's an
6:08
deployment just realize that there's an
6:08
deployment just realize that there's an option for initializing Dapper on
6:10
option for initializing Dapper on
6:10
option for initializing Dapper on kubernetes and you can uninstall Dapper
6:13
kubernetes and you can uninstall Dapper
6:13
kubernetes and you can uninstall Dapper as well I actually showed you this um
6:16
as well I actually showed you this um
6:17
as well I actually showed you this um Dapper oninstall if you use Dapper
6:19
Dapper oninstall if you use Dapper
6:19
Dapper oninstall if you use Dapper oninstall this is going to uh Delete the
6:22
oninstall this is going to uh Delete the
6:22
oninstall this is going to uh Delete the side card binaries but it's not going to
6:25
side card binaries but it's not going to
6:26
side card binaries but it's not going to remove all the
6:27
remove all the
6:27
remove all the containers and with the dash dash all
6:31
containers and with the dash dash all
6:31
containers and with the dash dash all you're going to remove everything and
6:34
you're going to remove everything and
6:34
you're going to remove everything and that's actually what I did now let's
6:36
that's actually what I did now let's
6:36
that's actually what I did now let's talk about toer C remember that this is
6:38
talk about toer C remember that this is
6:38
talk about toer C remember that this is the pop up session but before I do that
6:43
the pop up session but before I do that
6:43
the pop up session but before I do that I need to explain some other things
6:45
I need to explain some other things
6:45
I need to explain some other things related to Dapper okay bear with me
6:47
related to Dapper okay bear with me
6:47
related to Dapper okay bear with me friends Dapper CLI this is the one

that you're using okay some essential commands dopper version uh very easy to
8:08
commands dopper version uh very easy to
8:08
commands dopper version uh very easy to explain the upper version it's going to
8:10
explain the upper version it's going to
8:10
explain the upper version it's going to tell you the version that you're running
8:13
tell you the version that you're running
8:13
tell you the version that you're running you can also use the flag dash dash
8:16
you can also use the flag dash dash
8:16
you can also use the flag dash dash version and you can see that I'm using
8:18
version and you can see that I'm using

8:20
right now those
8:20
right now those versions and in a couple of weeks maybe
8:23
versions and in a couple of weeks maybe
8:23
versions and in a couple of weeks maybe three weeks we can use 1.15 which is
8:27
three weeks we can use 1.15 which is

just for understanding all the different
8:41
just for understanding all the different options that you have for instance
8:43
options that you have for instance
8:43
options that you have for instance Dapper help is the same as Dapper and
8:46
Dapper help is the same as Dapper and
8:46
Dapper help is the same as Dapper and let's say that I want to use some I
8:49
let's say that I want to use some I
8:49
let's say that I want to use some I don't know I don't remember all the
8:51
don't know I don't remember all the
8:51
don't know I don't remember all the things related to Dapper Ron this is a
8:54
things related to Dapper Ron this is a
8:54
things related to Dapper Ron this is a wrong command so you can pass Dash
8:57
wrong command so you can pass Dash
8:57
wrong command so you can pass Dash dashel and this is contextual right this
9:00
dashel and this is contextual right this
9:00
dashel and this is contextual right this is going to tell you everything about
9:03
is going to tell you everything about
9:03
is going to tell you everything about the Dapper wrong command Dapper list for
9:06
the Dapper wrong command Dapper list for
9:06
the Dapper wrong command Dapper list for listing all your application
9:08
listing all your application
9:08
listing all your application instances um and of course I don't have
9:12
instances um and of course I don't have
9:12
instances um and of course I don't have any kind of instance right now um there
9:15
any kind of instance right now um there
9:15
any kind of instance right now um there are no Dapper applications running so a
9:19
are no Dapper applications running so a
9:19
are no Dapper applications running so a dopper list uh no Dapper instances found
9:23
dopper list uh no Dapper instances found
9:23
dopper list uh no Dapper instances found and finally Dapper dashboard this is for
9:26
and finally Dapper dashboard this is for
9:26
and finally Dapper dashboard this is for opening up the
9:27
opening up the
9:27
opening up the dashboard so check this out Dapper
9:30
dashboard so check this out Dapper
9:30
dashboard so check this out Dapper dashboard it's going to run by default
9:33
dashboard it's going to run by default
9:33
dashboard it's going to run by default on this port and you can open up this
9:37
on this port and you can open up this
9:37
on this port and you can open up this dashboard in your browser so you can
9:40
dashboard in your browser so you can
9:40
dashboard in your browser so you can navigate and understand all the
9:42
navigate and understand all the
9:42
navigate and understand all the different Dapper components that are
9:44
different Dapper components that are
9:44
different Dapper components that are configured in this machine and all the
9:46
configured in this machine and all the
9:46
configured in this machine and all the dopper applications and so on okay very
9:50
dopper applications and so on okay very
9:50
dopper applications and so on okay very very useful but of course I don't have
9:52
very useful but of course I don't have
9:53
very useful but of course I don't have any kind of application right now so
9:55
any kind of application right now so
9:55
any kind of application right now so bear with me this is going to be fun at
9:58
bear with me this is going to be fun at
9:58
bear with me this is going to be fun at the end of the session
10:00
the end of the session
10:00
the end of the session or throughout the the session right okay
10:04
or throughout the the session right okay
10:04
or throughout the the session right okay so far so good running the side card
10:07
so far so good running the side card
10:07
so far so good running the side card remember that Dapper is meant to be used
10:10
remember that Dapper is meant to be used
10:10
remember that Dapper is meant to be used as a side car
10:13
as a side car
10:13
as a side car meaning for kubernetes is another
10:16
meaning for kubernetes is another
10:16
meaning for kubernetes is another container in the same pod and if you're
10:19
container in the same pod and if you're
10:19
container in the same pod and if you're using the self-hosted mode this is
10:22
using the self-hosted mode this is
10:22
using the self-hosted mode this is another different
10:24
another different
10:24
another different process um than your application okay so
10:30
process um than your application okay so
10:30
process um than your application okay so you can you can have your sidecar
10:32
you can you can have your sidecar
10:32
you can you can have your sidecar running in your machine your development

different process that's actually what I'm going to do right
10:42
I'm going to do right
10:42
I'm going to do right now okay so you need to run the side car
10:46
now okay so you need to run the side car
10:46
now okay so you need to run the side car somehow remember Dapper d. XE that's the
10:49
somehow remember Dapper d. XE that's the
10:49
somehow remember Dapper d. XE that's the side card and you need to run it but you
10:52
side card and you need to run it but you
10:52
side card and you need to run it but you don't go to your user folder d uh
10:56
don't go to your user folder d uh
10:56
don't go to your user folder d uh forward slash. dopper and then Dapper d.
11:00
forward slash. dopper and then Dapper d.
11:00
forward slash. dopper and then Dapper d. XE what you do is you invoke the Dapper
11:04
XE what you do is you invoke the Dapper
11:04
XE what you do is you invoke the Dapper run command Dapper run so this is just
11:08
run command Dapper run so this is just
11:08
run command Dapper run so this is just for running the side car let's do that
11:10
for running the side car let's do that
11:11
for running the side car let's do that let's see what happens Dapper run hey
11:13
let's see what happens Dapper run hey
11:13
let's see what happens Dapper run hey Dapper I want to run the side car and as
11:16
Dapper I want to run the side car and as
11:16
Dapper I want to run the side car and as you can see this is displaying a lot of
11:19
you can see this is displaying a lot of
11:19
you can see this is displaying a lot of information it's quite
11:22
information it's quite
11:22
information it's quite Bose and at the end of the of the logs
11:26
Bose and at the end of the of the logs
11:26
Bose and at the end of the of the logs we can see that this is running okay so
11:29
we can see that this is running okay so
11:29
we can see that this is running okay so we have right now the dber side card
11:31
we have right now the dber side card
11:31
we have right now the dber side card running in this machine there are some
11:33
running in this machine there are some
11:33
running in this machine there are some other information quite useful when
11:36
other information quite useful when
11:36
other information quite useful when you're building um your Dapper
11:39
you're building um your Dapper
11:39
you're building um your Dapper application such as okay for instance
11:42
application such as okay for instance
11:42
application such as okay for instance this flag was
11:44
this flag was
11:44
this flag was deprecated this this is very useful for
11:48
deprecated this this is very useful for
11:48
deprecated this this is very useful for specifying another
11:49
specifying another

specifying another folder where you can have some Jam files
11:52
folder where you can have some Jam files

so uh I don't know maybe here we can can see that this is disabled and some other
12:01
see that this is disabled and some other
12:01
see that this is disabled and some other things related to the dopper side car
12:03
things related to the dopper side car

log um content uh however you can be sure that this is quite useful sometimes
12:16
sure that this is quite useful sometimes
12:16
sure that this is quite useful sometimes when you're debugging or you are uh
12:20
when you're debugging or you are uh
12:20
when you're debugging or you are uh troubleshooting your applications anyway
12:22
troubleshooting your applications anyway
12:23
troubleshooting your applications anyway the thing friends is that this Dapper
12:26
the thing friends is that this Dapper
12:26
the thing friends is that this Dapper side car is running right now and check
12:28
side car is running right now and check

side car is running right now and check this out
12:29
this out

something right this is
12:36
something right this is returning this app ID this was just a
12:40
returning this app ID this was just a
12:40
returning this app ID this was just a random name created by this Dapper side

13:16
Dapper dashboard let's go ahead and
13:16
Dapper dashboard let's go ahead and create the dashboard again navigate to
13:18
create the dashboard again navigate to

create the dashboard again navigate to the dopper dashboard and now we can see
13:21
the dopper dashboard and now we can see

that you can pass to the dopper Rong command such as app ID app ID is when
14:45
command such as app ID app ID is when

command such as app ID app ID is when you specify the app name so for instance
14:48
you specify the app name so for instance
14:48
you specify the app name so for instance D Ron app ID my application one right my

okay here's another
15:00
okay here's another flag Dapper HTTP Port this is the port
15:06
flag Dapper HTTP Port this is the port
15:06
flag Dapper HTTP Port this is the port number where Dapper is going to listen
15:08
number where Dapper is going to listen
15:08
number where Dapper is going to listen to or listen on for requests okay so you
15:14
to or listen on for requests okay so you
15:14
to or listen on for requests okay so you can you know have this granular control
15:18
can you know have this granular control
15:18
can you know have this granular control over the HTTP port
15:20
over the HTTP port
15:20
over the HTTP port number so you can use Dapper HTTP Port
15:23
number so you can use Dapper HTTP Port
15:23
number so you can use Dapper HTTP Port of course this is for HTTP
15:25
of course this is for HTTP
15:25
of course this is for HTTP Communications and you can also have the

one is the command that we use for running net applications
16:41
running net applications
16:41
running net applications right so check this out this uh command
16:44
right so check this out this uh command

an example taken from the
18:05
an example taken from the official uh dopper
18:07
official uh dopper
18:07
official uh dopper documentation so you can see that this
18:10
documentation so you can see that this

web app and backend that's those are the names okay web app and back end and you
18:21
names okay web app and back end and you
18:21
names okay web app and back end and you pass some different flags and parameters
18:24
pass some different flags and parameters
18:24
pass some different flags and parameters to each

18:28
application for instance one application could be a python application and this
18:30
could be a python application and this
18:30
could be a python application and this other one could be a net application and
18:32
other one could be a net application and
18:32
other one could be a net application and this other one a Java application it
18:34
this other one a Java application it
18:34
this other one a Java application it doesn't matter you specify in this

to
18:42
to run um as a group okay and then you can

run um as a group okay and then you can stop the
18:47
stop the
18:48
stop the entire um group of applications if you
18:50
entire um group of applications if you
18:51
entire um group of applications if you use doer stop and then pass the um jam
18:55
use doer stop and then pass the um jam
18:55
use doer stop and then pass the um jam file
18:56
file
18:56
file name or if you
18:59
name or if you
18:59
name or if you use the default Dapper do jaml name you
19:03
use the default Dapper do jaml name you
19:03
use the default Dapper do jaml name you just pass the directory name so this is
19:07
just pass the directory name so this is
19:07
just pass the directory name so this is similar to uh Docker compose as you can
19:09
similar to uh Docker compose as you can
19:09
similar to uh Docker compose as you can see
19:10
see
19:10
see your yeah I think that Docker compose is
19:13
your yeah I think that Docker compose is
19:14
your yeah I think that Docker compose is the best uh example or that we can
19:16
the best uh example or that we can
19:16
the best uh example or that we can compare to when running multiple

19:58
far so good right you run the dapper
19:58
far so good right you run the dapper side card and this side card is

use erpc right and for instance you can use posman or curl for sending some
20:17
use posman or curl for sending some
20:17
use posman or curl for sending some requests and then receiving some
20:19
requests and then receiving some
20:19

20:23
responses from the side car however
20:23
responses from the side car however that's not very real
20:25
that's not very real
20:25
that's not very real world uh when you're building Dapper
20:27
world uh when you're building Dapper
20:27

something uh that is uh battle tested and well um uh designed and that's why
20:42
and well um uh designed and that's why
20:43
and well um uh designed and that's why our friends from Dapper created a lot of
20:45
our friends from Dapper created a lot of
20:45
our friends from Dapper created a lot of different sdks that we can use in
20:48
different sdks that we can use in

object this is a class okay this is the class that was created and it's inside
22:39
class that was created and it's inside
22:39
class that was created and it's inside this SDK of course you need to add this
22:42
this SDK of course you need to add this
22:42
this SDK of course you need to add this net package right and I'm going to show
22:46
net package right and I'm going to show
22:46
net package right and I'm going to show you that today and when you add the
22:49
you that today and when you add the
22:49
you that today and when you add the Nugget
22:51
Nugget
22:51
Nugget package then you can use the dopper
22:55
package then you can use the dopper
22:55
package then you can use the dopper client so this this DPP dopper client
22:59
client so this this DPP dopper client
23:00
client so this this DPP dopper client abstracts
23:01
abstracts
23:01
abstracts away the the all the communication to
23:05
away the the all the communication to
23:05
away the the all the communication to the side car okay so allows you to
23:08
the side car okay so allows you to

23:52
safe okay so how in the world you use
23:52
safe okay so how in the world you use the Dapper SDK in net first you need to
23:57
the Dapper SDK in net first you need to
23:57
the Dapper SDK in net first you need to add the Dapper you know the N package
24:01
add the Dapper you know the N package
24:01
add the Dapper you know the N package and then you register Dapper by using
24:04
and then you register Dapper by using
24:04
and then you register Dapper by using add dopper okay you just use this quite
24:10
add dopper okay you just use this quite
24:10
add dopper okay you just use this quite super helpful
24:11
super helpful
24:11
super helpful command um or method for registering
24:14
command um or method for registering
24:14
command um or method for registering Dapper and that's

Dapper and that's it that is it my friends d add Dapper
24:19
it that is it my friends d add Dapper
24:19
it that is it my friends d add Dapper and that's it so when you do this then
24:24
and that's it so when you do this then
24:24
and that's it so when you do this then you're able to inject the dopper client

ahead and open up visual studio code okay and the first thing that I
27:20
code okay and the first thing that I
27:20
code okay and the first thing that I want to do friends is I want to use I
27:23
want to do friends is I want to use I

want to do friends is I want to use I wanna I want to search for the nuget
27:26
wanna I want to search for the nuget
27:26
wanna I want to search for the nuget package okay
27:28
package okay
27:28
package okay that has the doer client object okay so
27:33
that has the doer client object okay so
27:33
that has the doer client object okay so for instance we can go let me show you
27:36
for instance we can go let me show you
27:36
for instance we can go let me show you that in nuget.org
27:39
that in nuget.org

Dapper asp.net core right uh one14 since that's the latest version of dapper at
28:40
that's the latest version of dapper at
28:40
that's the latest version of dapper at the moment of this
28:42
the moment of this
28:42
the moment of this recording and actually that's it
28:45
recording and actually that's it
28:46
recording and actually that's it actually that is it friends okay now
28:51
actually that is it friends okay now
28:51
actually that is it friends okay now program.cs and here I can go ahead and
28:55
program.cs and here I can go ahead and
28:55
program.cs and here I can go ahead and let's
28:56
let's
28:56
let's first doet
29:00
you know for intellisense to work
29:02
you know for intellisense to work
29:02
you know for intellisense to work sometimes it doesn't work right away in
29:04
sometimes it doesn't work right away in
29:04
sometimes it doesn't work right away in Visual Studio code add dopper that is
29:09
Visual Studio code add dopper that is
29:09
Visual Studio code add dopper that is it this is the way you use an asp L core
29:13
it this is the way you use an asp L core
29:13
it this is the way you use an asp L core for registering dopper and thanks to
29:16
for registering dopper and thanks to
29:16
for registering dopper and thanks to this command I can go ahead and navigate
29:20
this command I can go ahead and navigate
29:20
this command I can go ahead and navigate to the controllers in here I can inject
29:22
to the controllers in here I can inject
29:22
to the controllers in here I can inject oper CLI but of course I want this to be
29:26
oper CLI but of course I want this to be
29:26
oper CLI but of course I want this to be something meaningful
29:29
something meaningful
29:29
something meaningful let's
29:30
let's
29:30
let's say I don't know let's change this name
29:34
say I don't know let's change this name
29:34
say I don't know let's change this name to something
29:35
to something
29:35
to something like um sales
29:40
like um sales
29:40
like um sales controller remember that I I'm super
29:44
controller remember that I I'm super
29:44
controller remember that I I'm super creative when naming things okay sales
29:48
creative when naming things okay sales
29:48
creative when naming things okay sales controller so the thing about this
29:50
controller so the thing about this
29:51
controller so the thing about this controller is that we have you know some
29:54
controller is that we have you know some
29:54
controller is that we have you know some sales who are selling something that
29:57
sales who are selling something that
29:57
sales who are selling something that actually it doesn't matter what I want
29:59
actually it doesn't matter what I want
29:59
actually it doesn't matter what I want you to see right now is how to inject
30:03
you to see right now is how to inject
30:03
you to see right now is how to inject dopper client dopper client dopper
30:06
dopper client dopper client dopper
30:06
dopper client dopper client dopper client and that is it so I can go ahead
30:10
client and that is it so I can go ahead
30:10
client and that is it so I can go ahead and use that Dapper client object in my
30:13
and use that Dapper client object in my
30:13
and use that Dapper client object in my endpoints for instance public casing
30:15
endpoints for instance public casing
30:15
endpoints for instance public casing task eye action result or something get
30:19
task eye action result or something get
30:19
task eye action result or something get or whatever and then I can doer client
30:24
or whatever and then I can doer client
30:24
or whatever and then I can doer client and
30:25
and
30:25
and use the methods right
30:28
use the methods right
30:28
use the methods right you can see that I have different
30:30
you can see that I have different
30:30
you can see that I have different methods for interacting with the side
30:33
methods for interacting with the side
30:33
methods for interacting with the side car and today I'm going to show you
30:36
car and today I'm going to show you
30:36
car and today I'm going to show you publish event async which is the way
30:40
publish event async which is the way
30:40
publish event async which is the way that we
30:41
that we
30:41
that we use um for sending a

the screen at the right side and those services are interested in that
33:31
services are interested in that
33:31
services are interested in that particular event or message so they
33:36
particular event or message so they
33:36
particular event or message so they subscribe and when the event
33:40
subscribe and when the event
33:40
subscribe and when the event happens then those Services receive the

42:42
popop okay
42:44
okay
42:44
okay then topic
42:46
then topic
42:46
then topic name so if you happen to have experience
42:51
name so if you happen to have experience
42:51
name so if you happen to have experience using message Brokers you know that are
42:54
using message Brokers you know that are
42:55
using message Brokers you know that are some there's the topic topic right
42:58
some there's the topic topic right
42:58
some there's the topic topic right Topic's topic and it means that it's
43:01
Topic's topic and it means that it's
43:01
Topic's topic and it means that it's like a sh channel right is the topic
43:04
like a sh channel right is the topic
43:04
like a sh channel right is the topic name that's a um uh message broker kind
43:10
name that's a um uh message broker kind
43:10
name that's a um uh message broker kind of a topic anyway no pun intended the
43:14
of a topic anyway no pun intended the
43:15
of a topic anyway no pun intended the thing is that we need to specify the
43:16
thing is that we need to specify the
43:16
thing is that we need to specify the topic here so for instance let's say
43:19
topic here so for instance let's say
43:19
topic here so for instance let's say sales or sales information or whatever
43:24
sales or sales information or whatever
43:24
sales or sales information or whatever folds your boat it doesn't matter it's
43:26
folds your boat it doesn't matter it's
43:26
folds your boat it doesn't matter it's just the name of the
43:27
just the name of the
43:27
just the name of the topic what's cool here is that you don't
43:31
topic what's cool here is that you don't

version of Visual Studio anyway let me go back to visual studio code and see if
49:37
go back to visual studio code and see if
49:37
go back to visual studio code and see if this new instance has the intelligence
49:42
this new instance has the intelligence

sale or something right on sale and I want to use this following
51:13
sale and I want to use this following
51:13
sale and I want to use this following attribute remember that I'm building the
51:17
attribute remember that I'm building the
51:17
attribute remember that I'm building the receiving part of this solution I'm
51:20
receiving part of this solution I'm
51:20
receiving part of this solution I'm publishing the
51:21
publishing the

publishing the event now I need the receiving part uh
51:25
event now I need the receiving part uh
51:25
event now I need the receiving part uh of this solution
51:27
of this solution
51:27
of this solution so it looks like there's something wrong
51:30
so it looks like there's something wrong
51:30
so it looks like there's something wrong with my intelligence it doesn't matter
51:33
with my intelligence it doesn't matter
51:33
with my intelligence it doesn't matter let me go ahead
51:37
and yes I need the topic name you might
51:42
and yes I need the topic name you might
51:42
and yes I need the topic name you might remember the topic name that I used
51:45
remember the topic name that I used
51:45
remember the topic name that I used before anyway let's do the following
51:48
before anyway let's do the following
51:48
before anyway let's do the following because intelligence is like U kind of
51:51
because intelligence is like U kind of
51:51
because intelligence is like U kind of crazy right now it doesn't
51:54
crazy right now it doesn't
51:54
crazy right now it doesn't matter I'm creating the receiving part I
51:58
matter I'm creating the receiving part I
51:58
matter I'm creating the receiving part I created already the publishing part so
52:02
created already the publishing part so
52:02
created already the publishing part so let's go ahead actually and here to my
52:05
let's go ahead actually and here to my
52:05
let's go ahead actually and here to my service a and let me show you how to run
52:10
service a and let me show you how to run
52:10
service a and let me show you how to run this remember how to run the side car
52:14
this remember how to run the side car
52:14
this remember how to run the side car and then app
52:17
and then app
52:17
and then app ID okay app ID let's say service
52:22
ID okay app ID let's say service
52:22
ID okay app ID let's say service a and then the dopper a HTTP Port let's
52:29
a and then the dopper a HTTP Port let's
52:29
a and then the dopper a HTTP Port let's say
52:30
say
52:30
say 50,000 and app
52:34
50,000 and app
52:34
50,000 and app Port let's say 5,000 just like I showed
52:38
Port let's say 5,000 just like I showed
52:38
Port let's say 5,000 just like I showed you in the PowerPoint
52:41
you in the PowerPoint
52:41
you in the PowerPoint slides right so the
52:44
slides right so the
52:44
slides right so the separator comes
52:46
separator comes
52:46
separator comes next and this is the
52:49
next and this is the
52:49
next and this is the place where you specify the up specific

place where you specify the up specific
52:53
place where you specify the up specific commands and instructions such as net
52:57
commands and instructions such as net
52:57
commands and instructions such as net Ron and then URLs
53:01
Ron and then URLs
53:01
Ron and then URLs HTTP and let's say that I want to use
53:04
HTTP and let's say that I want to use
53:05
HTTP and let's say that I want to use port
53:06
port
53:06
port 5,000
53:08
5,000
53:08
5,000 right because otherwise you need to you
53:11
right because otherwise you need to you
53:11
right because otherwise you need to you need to map the port where your
53:15
need to map the port where your
53:15
need to map the port where your application is running on and use that
53:18
application is running on and use that
53:18
application is running on and use that accordingly for instance if I use doet
53:21
accordingly for instance if I use doet
53:21
accordingly for instance if I use doet run this is just for running this
53:23
run this is just for running this

53:32
random randomly created in assign Port
53:32
random randomly created in assign Port which is
53:34
which is
53:34
which is 5158 so in this case I had to be sure
53:39
5158 so in this case I had to be sure
53:39
5158 so in this case I had to be sure that uh when I specify this
53:44
that uh when I specify this
53:44
that uh when I specify this command that I I it disappeared D Ron
53:48
command that I I it disappeared D Ron
