You can also use the same technique to run a node js script.&nbsp;<\/p>\n\n\n\n<p>First, we need to modify our code to run on demand instead of on a schedule because Crontab will take care of the scheduling.&nbsp;<\/p>\n\n\n\n<p><script><br \/>\n            \/* This is ugly, but to ensure we only create this function once, and only call<br \/>\n            each JS library once, we need to check here in case there are multiple Wagtail<br \/>\n            blocks on this page.

Save it and close the file. Your script should run as expected.\u00a0<\/p>\n\n\n\n<p>If you\u2019re not clear about the Crontab configurations, my best advice is to use <a href=\"https:\/\/crontab.guru\/\" target=\"_blank\" rel=\"noopener\">Crontab.guru<\/a>.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Crontab or Python Schedule?<\/h2>\n\n\n\n<p>Both tools are excellent for scheduling tasks. But depending on the circumstances, one works better than the other.&nbsp;<\/p>\n\n\n\n<p>The plus point of Python\u2019s schedule is its flexibility and friendliness. Anyone can understand the schedule just by reading it. You don\u2019t even have to refer to the documentation.&nbsp;<\/p>\n\n\n\n<p>Although crontab configurations are not that hard to understand, beginners will need a little effort to understand them.&nbsp;<\/p>\n\n\n\n<p>Everything is in one place, which makes the schedule library straightforward. In Crontab, you\u2019d have to edit the <a href=\"https:\/\/www.the-analytics.club\/toml-config-files\/\" title=\"A Brief Guide To Manage Configurations Using TOML Files\">configuration file<\/a> outside your developing module. If someone else wants to use your application, you\u2019d have to instruct them.&nbsp;<\/p>\n\n\n\n<p>Also, if I want to create a new schedule, All I have to do is to annotate the function with another. <code>@repeat<\/code>. Also, in Crontab, you\u2019d add another configuration line. But not as swift as you\u2019d do in a <a href=\"https:\/\/www.the-analytics.club\/debug-skills-python\/\" title=\"Debug Python Scripts Like a Pro\">Python script<\/a>.<\/p>\n\n\n\n<p>These pros make Python\u2019s schedule library suitable for most use cases. But take a look at the <a href=\"https:\/\/schedule.readthedocs.io\/en\/stable\/#when-not-to-use-schedule\" target=\"_blank\" rel=\"noopener\">library\u2019s documentation page<\/a>.&nbsp;<\/p>\n\n\n\n<blockquote class=\"wp-block-quote\">\n<p>This library is designed to be a simple solution for simple scheduling problems. You should probably look somewhere else if you need to remember schedule between restarts, sub-second precision execution, multiple threads, time zones, workdays or holidays support.\u200a\u2014\u200aschedule library&nbsp;docs.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">Final Thoughts<\/h2>\n\n\n\n<p>Running tasks on a schedule is a <a href=\"https:\/\/www.the-analytics.club\/how-can-i-start-a-software-project-without-knowing-how-to-code\/\" title=\"How Can I Start A Software Project Without Knowing How To Code?\">frequent need in software development<\/a>. I often find it useful to run the little productive hacks I do on the go.&nbsp;<\/p>\n\n\n\n<p>I\u2019ve been using Crontab for several years, thinking that it\u2019s the only way to do the job. But the schedule Python library made it super simple.&nbsp;<\/p>\n\n\n\n<p>It may not be the perfect tool for every instance. But not everything we do daily needs more sophisticated techniques.&nbsp;<\/p>\n\n\n\n<p>Now, I\u2019ve converted many such periodic executions to Python schedules.&nbsp;<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-dots\"\/>\n\n\n\n<blockquote class=\"wp-block-quote\">\n<p>Thanks for the read, friend.
