Whenever VS Chart.js

Learn about Unix cron and use the whenever gem.

there are cronjob gems available, i believe https://github.com/javan/whenever or so seems to be used frequently

- Use them on a specific schedule as needed by your application, such as taking backups, sending periodic reminders or notifications for users, cleaning the database tables, etc. You can use a gem such as Whenever for managing scheduled cron jobs.

whenever gem is used in Rails applications to schedule cron jobs e.g. send email notification about monthly expenditure on the 1st of each month.

Then you can use the whenever gem to schedule stuff.

- [whenever](https://github.com/javan/whenever)

whenever

There are multiple ways to achieve this. Probably the simplest and most reliable is to rely on cron to run your process every minute. Cron keeps track of time and executes your script each minute. This has the added benefit of avoiding a long running process (which can have its own issues). You can even have your script install it’s own cron job using the Whenever gem.

Rake tasks can be called from Cron, so we'll use the Whenever Gem to automatically add our job to our Crontab during deployment, and keep our schedule in change control.

ChartsJS for inspiring me with the pie chart.

Most of frontend libraries are made with Vanilla JS. An example of library that you might frequently use is "Chart.js". But React is not compatible with Chart.js so here it comes "React-chartjs-2" A wrapper library to work with Chart.js in React ecosystem. Oh you want to use "three.js" for some cool 3D? you will need "React-three/fiber". In my case, I need to implement "telegram-web-app", not so fast, I have to create my own wrapper to be able to use it.

Chart.js

Chart.js is a free, open-source JavaScript library for data visualization, which supports eight chart types: bar, line, area, pie, bubble, radar, polar and scatter. It's licensed under the permissive MIT license and is renowned for being flexible, lightweight, easy to use and extendible.

They are images so it could be any number of things, datawrapper, charts.js, d3.js to name a few options.

Charts.js for creating diagrams

Connie Leung wrote a tutorial to demonstrate how these new hooks work, integrating an Angular app with the Chart.js library: "DOM reading and writing with new lifecycle hooks in Angular"

Thanks to all who participated in our 2023 Self-Host User Survey! Below is a link to the results, which we've visualized using Chart.js.

Chart.js

I used chart.js [0], but I don't necessarily endorse it - it's just what I knew how to use quickly. I usually try to keep my posts free from javascript, and could have used a different tool that gives me SVG data or images.
