Scheduler in Laravel 8 | What is The Scheduler in Laravel? | Laravel Scheduler Explained

what's up developers it's dory here and welcome back to a new video where we're going to talk about the scheduler in laravel quick pause do you want to support the channel and want me to continue on pushing content well you can support the channel through patreon you'll get some awesome benefits such as a private discord group where everyone is helping each other out so if you are interested to join the link will be in the description down below larval scheduler is something you'll see quite often built into web applications on the web even if you're not aware of it there's a big possibility that in web development certain tasks needs to be done regularly let's imagine an e-commerce for a second where you get new discounts on let's say every friday of the week do you want to send product discounts manually or do you want to run a scheduler that does it on a certain time on a certain day in the week it's pretty repetitive if you do it yourself right it costs so much time to do it before the day starts on every friday of the week it's obviously something that you can do when you have a new ecommerce store but it might get annoying after quite a while you might have heard the term cronjob before which is a tool that a lot of developers had to write themselves back in the days and actually even up until this point to be honest with larval scheduler you can make tasks like i mentioned super simple you basically have to write your task in code define the time frame run an artisan command and you're done i want to showcase this in the best possible way and therefore we do need to create a new artist command that we can run in order to run our scheduler so let's navigate to the cli and in here let's perform php artisan or php artisan list you'll find a complete list of all available artisan commands that we have in the project and if we scroll up to the make section right here you will find the option right here which is the third one called make colon command which will create a new artisan command for you so let's do that let's say php artisan make calling command with a new class or file name called daily message and what this eventually will do is basically sending a new message on a daily basis to a client let's hit enter the command that we just performed create a new class called daily message if we navigate back to visual studio code inside the app folder console folder there is a folder called commands with a file called daily message now i won't go over the namespace use statement and class but the most important thing right here is a property called signature now this will eventually be the terminal command that we need to perform in order to run our scheduler so let's keep it related to the class name let's change it to message column daily let's also change the description to let's say artisan command to send daily messages save it if we navigate back to the cli hit the arrow up twice to run php artisanal list scroll up to the command which starts with the letter m of message right here you can find it it even has his own header of message so we basically created a new command called message collin daily which is an artisan command to send daily messages now if we run it right now let's actually do it so php artisan message colon daily you'll see that nothing will happen because we haven't defined anything inside the command this is actually pretty good because it should return nothing since if we navigate back to visual studio code scroll down to the handle method where the actual magic happens with our scheduler you'll see that it's returning 0. whenever you want to perform some kind of magic with your artisan command you got to use the handle method defined at the bottom of the command so let's get rid of it and i want to start off pretty simple so let's echo out a piece of text of this is my first basic scheduler save it navigate back to visual studio code hit the arrow up run it again and as you can see this is my first basic scheduler has been printed out now we still haven't interacted with the scheduler right at this moment we haven't used our scheduler yet because it's only being printed out once what we need to do is to set up the right command they would like to schedule inside the kernel.php file of the console folder so let's open it scroll down to the schedule method right here today's video is brought to you by cloudways a managed hosting platform for your applications cloudways has enabled businesses to scale and reach new milestones instead of worrying about server hassles with reliable 24 7 support cloudways offers complete peace of mind from server level nightmares furthermore its superior tools and works enhance your productivity so you can focus on creating incredible experiences with your applications it's a fast managed solution for agencies smbs and e-commerce businesses what i personally like about clyde waze is their slogan moving dreams forward you should be able to see a protected function called schedule right here with a line commented what we need to do is to inject our command inside the command method so let's uncomment it first all right inside the command method we're basically going to pass in a string of the command that we want to schedule and obviously it will be message collin daily now here comes the most important part of our scheduler what we're going to do right now is to schedule them so that larval keeps track of time passing and evaluates whether it's time to run it again or not at the moment you'll see that a hourly method is being called right here but there is a complete list of time frames that we can use right here so let's go over them real quick you can see that there are a lot of commands that we have right here and i got four more screens that we can cover we can run a scheduler every minute every 5 minutes 10 minutes 30 minutes or even every hour like we just saw in the example code but we could also run it daily so it will be run at midnight on a daily basis you could also set a time so if you don't want to run it on midnight you could basically say well run it daily at 10 pm instead of saying that we want to run it daily on a midnight we could also add a param which will be the time so we will run daily on a specific time you could also do it twice on a day which accepts two params of the times we can run it weekly weekly on a specific day and time once a month and you can specify which day of the month as well now besides that you can run it quarterly so every 3 months yearly so every midnight of the 1st of january we have a when and skip method which accepts both a closure which will limit the task when the closure returns true or false you can run it daily between a certain time so let's say between 2 pm and 10 pm but you could also limit it so let's say that you don't want to run it between 8 am and 12 pm you can say that you only want to run a command on weekdays so no saturday and sunday but you can also specify the days so sunday monday tuesday wednesday thursday friday and saturday let's change our method name to every minute instead of every hour so every minute so our echo will be printed out every minute instead of every hour at the moment the scheduler does not know where or how it should echo out a task that we got inside our artisan command so there are three different options on how you could output a task to a file so what we could do is to align it on the line below chain another method right here called append output 2. this method accepts one parameter which will be the location so let's say that we want to output our artisan command to the scheduler dot log file this will add a new file inside the root over directory and it will append the output so the echo that we got every minute into the scheduler so there's one more thing left and that's telling the scheduler that it needs to do its job so let's open the cli right inside visual studio code and in here let's perform php artisan schedule colon work hit enter so as you can see it has executed our command once so we need to wait one more minute and in the meantime i'm just going to tell you about the other two methods that we can use to output tasks instead of using the append output 2 we could also use the send output methods as well what this will do is only print the echo out once and the append output will print out every single time the scheduler is being called so let me open the scheduler.log file as you can see this is my first basic scheduler has been printed out and let's wait until the second iteration our second execution has been performed as well and this is the first basic scheduler has been printed out twice right now so let me quit it off by pressing ctrl z inside the terminal all right now let me remove the text that we got right here close it off now there's one more thing that i need to show you since you might work with different continents than let's say your future client and running a scheduler will have a different time for you than for your client for that we can define a default time zone now this can be done by chaining another method in the schedule method of our kernel so right here but the best way to do this is to create a separate method of the kernel i'm living in the netherlands and if i run my scheduler it will run it in the european time zone but let's say that my client works in chicago so what we could do is to go right below our schedule method create a new public function called schedule time zone and what we're going to do right here is to say return a new time zone of america forward slash chicago right now all of our schedule times will be defined in american time zone and this is easy if you want to schedule something at midnight now this was it for this video where i showed you how you could easily schedule certain tasks in laravel if you do like my content and you want to see more leave this
