[0:00] welcome to bed films and let me
[0:01] introduce you with an official package
[0:04] of level which is called larval horizon
[0:07] this is a great package and let's first
[0:10] quickly get started with this package by
[0:12] using this composer command to have this
[0:16] inside our level application so he'll is
[0:19] a fresh installation of lateral and I
[0:21] will say composer require level /
[0:23] horizon-- so this package is very useful
[0:27] when you are using cues with cue driver
[0:31] as readies so it provides a beautiful
[0:34] dashboard and some configuration for
[0:36] your level power red excu so very
[0:39] important thing is you need to use cue
[0:42] driver as reddit's this package provides
[0:44] this kind of cool dashboard where you
[0:47] can have number of jobs number of fill
[0:49] job number of processes and you can also
[0:51] retry some field job but let's first see
[0:55] why we need this kind of package so yeah
[1:00] it is installed so here I am and I will
[1:02] create a simple notification so make
[1:05] notification called user notification
[1:08] and this notification is just a simple
[1:10] notification which is sending an email
[1:12] to a user so I will open web dot PHP
[1:16] file and here I will go and send this
[1:20] notification to our user so find with
[1:24] the idea of one and notify user notify
[1:28] with new notify user notification okay
[1:34] so we need to grab this user also and at
[1:37] last we are going to return simply done
[1:40] so I have already configured my dot e
[1:43] and we file so with the test database
[1:46] and inside our test database we also
[1:49] have a one user with the ID of 1 this
[1:51] means if I start the server and if I go
[1:55] to localhost 8000
[1:58] you will see it is taking long time and
[2:02] by the way I also have configured this
[2:05] mail trap on our dot env file so here
[2:08] you can see I
[2:10] have configured so it always take time
[2:13] so even if I have one small refresh it
[2:15] take time to send an email because it's
[2:18] processing the sending part email
[2:20] sending part and now we have the to
[2:22] email we can make this sending of email
[2:26] or sending notification in a queue so I
[2:29] will open notify user and here we just
[2:33] need to say simply implementing so like
[2:36] implements should queue just by using
[2:41] this we have now moved this notification
[2:44] into queue
[2:45] okay so if i refresh this page still it
[2:49] is taking time because now if I go and
[2:53] on this dot Ian we file I said that
[2:56] queue connection is sync so this means
[3:01] it is thinking the queue we need to
[3:04] change it to red is because now we want
[3:06] the queue to be used by Redis once more
[3:11] restart the server and refresh this page
[3:14] and you can see instantly it's giving
[3:17] error because level by default uses PHP
[3:21] Redis
[3:22] so either you can install PHP Redis or P
[3:26] Redis so once more go to level
[3:28] documentation and on this documentation
[3:31] you can search for Redis and on this
[3:36] Redis part you can see we can you either
[3:38] use red Pierre IDs or PHP IDs but I
[3:41] personally like P Redis and it is very
[3:43] easy because it is also given here so
[3:45] you need to run this command composer
[3:48] command so let's stop the server run
[3:51] this composer command finally our peer
[3:54] Eddy's is installed so now once more we
[3:57] can start the server and go to localhost
[4:01] 8080 in this error but why we are
[4:06] getting this error because we need to
[4:08] tell to level that level don't use PHP
[4:11] Redis you need to use the period is how
[4:14] we can do that for that we need to go to
[4:18] the configuration of Redis so let's go
[4:20] and here inside config we have a
[4:24] spot inside this database at the last we
[4:28] can see we have this red spot and ready
[4:31] is using PHP Redis you can simply define
[4:34] it on env files so instead of doing this
[4:37] from here I will go here and define
[4:40] Redis client so like here right if
[4:44] client is P Redis very nice we have made
[4:49] changes in dot E and V file so we need
[4:51] to restart the server and one more try
[4:54] and this time with no error and super
[4:58] quickly no delay we have moved our email
[5:01] into this queues but once more if I
[5:06] delete everything from here refresh this
[5:08] page you can see we don't have any email
[5:11] this means our queues are not processed
[5:14] so how we can generally process so we
[5:17] can say PHP artisan queue work and then
[5:21] if I do this yes now I'm having the
[5:25] email because now these notification are
[5:28] processed that good but now comes our
[5:32] level horizon so let's now continue our
[5:35] installation of level horizon so we have
[5:38] installed it via this composer command
[5:41] but we need to run this command to
[5:43] install its effects so I will stop this
[5:46] queue worker and then I will say PHP
[5:49] artisan horizon : installed so it has
[5:52] done three things published the service
[5:54] provider some assets and the
[5:56] configuration so let's start with the
[5:58] configuration on this config folder we
[6:00] have this horizontal Asian and in this
[6:03] horizontal figuration the unique thing
[6:06] you can see we have this path which is
[6:08] horizon this means if you have server
[6:12] running you can simply go on localhost
[6:16] 8004 as on and then you can see you have
[6:20] a cool dashboard and instantly you can
[6:23] see it has picked two job because
[6:26] previously we have ran two jobs so
[6:29] without using queue worker and this
[6:33] means so we can simply see the recent
[6:35] job and other
[6:37] things like monitor and matrix but from
[6:41] where this dashboard came from the UI
[6:44] came from so you can see we have
[6:46] published the effects so we have the
[6:49] effects inside public vendor assets this
[6:52] is just for all the UI it is made
[6:55] overview GS and this is because of that
[6:58] one more thing we have published is
[7:01] service provider which is inside app
[7:04] provider and horizontals provider so in
[7:08] this horizontal provider we have a boot
[7:10] method and a gate method so you can see
[7:13] generally we can access this horizon--
[7:16] route even if I am not logged in but
[7:20] when you want to give access to this
[7:21] horizon dashboard just to one or two
[7:24] people you can just define the email
[7:27] here like this and then the user with
[7:31] this email ID when they are logged in
[7:34] then only they can able to access this
[7:38] route otherwise they will get 404 that's
[7:41] a simple configuration kind of things
[7:43] are related to resin but more is inside
[7:47] this horizon-- configuration file so we
[7:51] have seen that part next is it is going
[7:54] to use the connection so default
[7:56] connection of Redis and this by default
[7:59] prefix everything related to your
[8:03] application with horizontal in' if you
[8:06] want to make changes in this you need to
[8:09] give this information inside your dot
[8:12] env file and we can prove this also so I
[8:15] will go here and I will say red is CLI
[8:18] and if you don't have ready you can
[8:21] simply say brew install Redis if you are
[8:25] using Mac and for window you can I think
[8:27] you can simply find it so ready CLI and
[8:30] in this you can simply say keys and X
[8:35] tricks you can see we have this horizont
[8:38] notifier user and last snapshot this is
[8:42] just because of this horizon and this is
[8:45] actually the prefix we have we are
[8:47] talking about here that's cool there
[8:50] middleware and wait time then the most
[8:52] important thing here is this environment
[8:56] so we have this production environment
[8:58] and local end moment so let's talk about
[9:01] these things first so what about the
[9:05] previous two jobs we have put inside the
[9:08] queue so even if I go on localhost 8080
[9:13] processed it processed the notification
[9:17] but we are not getting any email inside
[9:20] our mail trap so you can see we don't
[9:22] have any email say it was eight minutes
[9:25] ago okay so to process the queue on this
[9:29] Redis with the help of horizon what you
[9:32] need to do you need to run the command
[9:34] which is PHP artisan horizon-- so it's
[9:38] just like you run command PHP artisan
[9:40] queue work similar to that we are using
[9:43] PHP artisan horizont so horizont started
[9:46] successfully and this means now we can
[9:49] see it is now converted to active so our
[9:52] dashboard is active cool so now because
[9:57] it is active you can see now but one
[10:01] previous notification is processed and
[10:03] once more if I clear this and refresh
[10:07] this page you can see now it says the
[10:10] for in the past one in the minute and it
[10:14] is now processed so it is very very cool
[10:18] and you can actually check the failed
[10:21] job so how we can check the failed job
[10:23] how we can fail a job one crazy thing I
[10:26] am going to do here is I'm going to say
[10:29] firstly inside tinker so PHP artisan
[10:32] tinker and I will say hey tinker create
[10:36] 50 user for me ok so now we have a 50
[10:40] user inside our database and this means
[10:43] now I can simply say grab me every user
[10:47] and for each user notify user very nice
[10:51] so let's see what's going to happen this
[10:53] is going to be very very interesting so
[10:56] now if I say refresh this page instantly
[10:59] we are getting done but now we have 50
[11:03] five jobs 54 now and five for the
[11:07] previous one so you can see it says 45
[11:10] jobs are in queue it's currently
[11:13] actually working four and then eight are
[11:16] failed because we have too much of jobs
[11:20] and we have just three processes so
[11:24] while this is processing let's go once
[11:26] again to the horizon-- configuration and
[11:29] you can see we can define the number of
[11:31] process so currently we have three
[11:34] processes and we have one retry
[11:36] that's why failed job comes here because
[11:39] they are just retried once so if I go to
[11:44] the failed jobs you can see we have a
[11:46] retry button so if I click here it's now
[11:49] read trying this so that's cool and now
[11:53] totally we have 35 and still four are
[11:57] inside the processes now total zero and
[12:00] if i refresh out of 50 40 jobs are
[12:04] failed this is not good so you can see
[12:08] we just have 10 email here so once again
[12:10] clear this and now what I'm going to do
[12:13] I'm going to make processes as 10 and
[12:16] retry as 5 and whenever you made change
[12:21] in horizontal you need to restart the
[12:24] horizon this is very important whenever
[12:26] you made changes in horizon-- or even in
[12:30] your notification you need to make
[12:33] restart this horizont process ok
[12:37] so for the sake of safety nets I'm also
[12:41] going to restart the server okay so we
[12:43] have 56 jobs here 40 are failed and now
[12:47] because we have restarted it's picked up
[12:49] that we are working with 10 processes
[12:53] cool refresh this page and now we have
[12:57] form 0 7 tasks and after completion you
[13:00] can see we have total 75 fail previously
[13:03] it was 40 and now it is 75 that means 35
[13:06] still feeling okay one more
[13:09] configuration you can do is like here it
[13:12] is defined that yeah so you can give the
[13:18] balance as simple it is given balance as
[13:21] simple so you can also say Auto so
[13:25] simple is very simple which configure it
[13:28] splits incoming job evenly into the
[13:31] process but if you say auto auto
[13:34] strategy adjust the number of vocal
[13:37] processors per cube based on the current
[13:40] workload ok so I am going to make it
[13:43] auto and then because we have made
[13:46] changes let's restart the horizon-- and
[13:49] now I'm going to say refresh and
[13:54] refreshing with that and now we have 168
[13:58] jobs so 50 more is now added so now we
[14:02] have 1 1 10 field job is still having 35
[14:05] failing but the processes took less time
[14:08] to processing all these queues so in
[14:11] that way you can actually define the
[14:14] last one which is false which is just a
[14:16] simple first-come first out kind of
[14:19] things on notifications or in the queues
[14:22] so this is a simple demonstration of how
[14:26] you can use level horizon and how you
[14:28] can configure with different
[14:30] configurations there are some more
[14:32] things on this horizontal continue or
[14:37] even terminate the horizon simply but in
[14:40] the next episode we are going to see how
[14:42] we can actually deploy this horizon
[14:44] error actually use this horizon on a
[14:47] server are you going to server with the
[14:50] supervisor as our client to run the PHP
[14:53] artisan horizon command ok if you liked
[14:56] this episode please give it a thumbs up
[14:58] and comment your views about level
[15:00] horizont is it a good when you have used
[15:03] and what makes you to use this package
[15:08] and don't forget to subscribe to this
