Hello Punk! I am again… Yes the Software Freestyle Engineer! Too handsome and stupid from the first time you think who am I.
What I want to share about the title above “Lazy as F! Isn’t About D.R.Y but B.A.F When Creating ChartJS”?
Let me tell to you…
What The D.R.Y? #
Yes! As you expect! Thank you very much…
What The B.A.F Mean? #
Boring As F! Thank you very much again. I think I am too handsome for doing the kinda stuff over and over in ChartJS! So, I creating component (yes, if you think kind of React-things) like using HTML. For efficiency:

I am a simple man and to the point! So, I created this ChartJS Class to wrap up the boring stuff and avoid switching between PHP and JavaScript over and over again. You know what I mean, right? Just say “Yes!” please…
I am a Software Engineer specializing in freestyle development, building web applications using PHP and HTMX. Therefore, I need to focus on writing less JavaScript code and shifting my state mindset to the server.
The Class Usage #
Instead of writing a bunch of JSON, I just need to write in my own preferred language (it's not a language, some people say from the background). Yes, PHP! That's part of Hypermedia, so I write using it.

Did you see that!?
- Defined the options overrides (optional)
- Create
ChartJSinstance and define the chart type - Add all what you need, Label, Datasets, chart configs
- and generate that code, add an id to draw the chart
That's it! You're welcome…
