Awesome!

[@shanujha7245]

do you have any plans to make it so that we can set up a schedule on an event, rather than hardcoding?

[@akkay5]

What happens if you want to push a update to the backend code and in doing so, your server restarts..

Is it possible to create a cronjob which executes every x minutes but at a specific date and time? For example: At 12:04, 12:09, 12:14, 12:19, etc

[@mafiacodes]

Yes

[@mafiacodes]

For example: At every 5th minute past hour 12 on day-of-month 26 in July. the expression would be " */5 12 26 7 * " , refer **crontab.guru/#*/5_12_26_7_*

Thanku sir ..

[@_PRADIPKUMAR]

Thanku sir this video very helpfull for me sir

[@livingstonedaniel982]

@mafiacodes If you’re creating schedules based on user inputs, that means you’d have to store the user-created cron expressions in a database or maybe KV store like redis and then load them into a code module where you’ll map over them to create the cron jobs right? How do you make sure that the cron job map in the code module is updated when a new user creates their own cron expression and it’s saved in the Db or Kv store especially given that the mapping in the code module is not sensitive to changes in the Database without the code being reloaded?

[@AlanDeveloperz]

Same code here, but the application just finishes and consolelog the job as NULL. Any idea why?

[@sdfsdfsdffdsfsdfsd123]

Hi Mafia, I would like to ask you, If I am setting loop to do something every 2 second, dont I need to set up some clear function? Thanks

[@-abhinab]

Will this work if I deploy my project in vercel severless function I want to schedule email for my website

[@saisuraj8762]

Thanks for the video, How if we need to stop the job after running exactly 4 times?

[@SCAPTION.]

//app.js //na terminal coloque: npm install node-schedule //após ter instalado por completo //no app.js insira: const schedule = require('node-schedule') //4° linha: const someDate = new Date ('')

[@zheroplayerofficial6944]

conseguiu fazer no nosso GMT?

[@willyhorizont8672]

thanks bhai

[@tanishhhhhhh]

Can we have multiple jobs scheduled at different times?

[@mafiacodes]

Yes

[@zheroplayerofficial6944]

i need help, the code is playing every minute and in the message is saying GMT+0000(coordinated universal time) and it canot stop playing the code

[@mafiacodes]

share the code plz

[@zheroplayerofficial6944]

[@jlreyes7756]

could this possibly end up having maximum call stack issues?

[@mafiacodes]

I don’t know

[@kamalCode]

Sir, microservice and networking services in nodejs

[@technoinfoworldwide2329]

Where we can see the real application of these things?

[@mddawoodalam6283]

but what if server goes down and restart again pls explain

[@claytonmuhoza6075]

You need go use PM2 in this case. PM2 will run your node app in background even if you restart your PC

Is it possible to reschedule cron job by stopping old scheduled cron job ?

[@mafiacodes]

Yes u can do so

[@Smile-to2ii]

I have a query. I want to run multiple compaigns of sending emails on the base of start date, end date and specific time, how can I achieve this in node js? Example. An email sending compaign going to start by 10th of January till 20th of January 2021 and email should be send on 11AM PST. How can I achieve this?

[@Smile-to2ii]

And it must be dynamic dates and time.

[@mafiacodes]

Use this cron expression "0 11 10-20 1 *" (At **11:00** on every day-of-month from 10 through 20 in January) **crontab.guru/#0_11_10-20_1_*

[@khoawasabi5769]

Can't this run with await function? if yes, how to schedule run with async function?

[@mafiacodes]

The same way an asynchronous function works

[@khoawasabi5769]

@@mafiacodes thanks for your answer. Example my app now start by "await aFunction.run();" how can I nest it inside a schedule.scheduleJob() properly? I have tried and it didn't work out. Thanks for your next input.

Can a node.js be scheduled server side Means a server will run javascript every 4 hours is it possible

[@mafiacodes]

yes you can do that very easily using a CRON in any UNIX/LINUX like systems

[@whoisnegii]

there were 3 users who were living in 3 different countries(and time zone are different for 3 of them) and suppose they have same birth date and I need to write a cron to wish them on email at exact 12am, then how will I write cron for this situation ?

[@mafiacodes]

Cron timing are according to the system in which they run, so u have to create 3 cron jobs according to the time zones of other 3 people

[@BlackBoy-gq4jt]

@@mafiacodes hi can you please help me . how the birthday cron should be done . i thought of two approach registering a cron job whenever user signup with birthday date for birthday wish cron job , second approach register a single cron job which checks every day at 12 am for the datebirth from database and if it matches with current date we can send an email ? which approach is used in production or i am wrong in both cases? please help.

[@mafiacodes]

Second approach is by far the best, and if ur worried about time zones as Karan said, then create a new scheduler function which takes in a cron expression and in that cron expression make time zone adjustments according to the use. So that a wish is sent exactly at 00:00

[@BlackBoy-gq4jt]

can you please make a video on auth0 (auth0.com/#!) for rolebased authentication , it uses openid connect . i tried it but got stucked in between .

[@hamza_dev]

Hi, This is the easiest explanation I have found after watching 3-4 bullshit videos. I am planning to create an Automated Bidding System for freelancing platforms. I wanna know if this will be good enough for handling multiple users. Since it is going to be used to check recent projects and bid on them. These jobs will have a very complex logic in themselves. Although I will be setting the logic in a different API but still I feel this is not going to be enough. I have done some research and I have found some solutions like using redis based library but I am not sure if redis is suitable for such tasks. Do you have any suggestions ?

[@mafiacodes]

I suggest for that u can use queues like bull / agenda / bree
