Let me ask, maybe you know: say I want to build a finance app that basically crunches a lot of data accessed from a DB, does some pretty intricate subsetting of the data, and produces Excel reports (XML). I currently do this with about 1300 lines of R code and a SQLite DB. Pretty lean and easy to use (was a bitch to write, tho, really stretched my understanding of lexical scoping and functional programming). If I wanted to webify this, the main challenge that I think I face is finding a framework that allows me to do all that nitty gritty data subsetting and summarizing - this is where R is really excellent, more flexible and expressive than SQL. What framework, if any, might you recommend? What kind of stack would be good for a beginner?
Most good libraries for interacting with DBs and Excel documents are written for the backend, so you’ll probably want to use Node with a simple web server like Express to serve pages, and do your heavy calculations, report generation, and DB stuff on the Node server. Making a server seems complex but Express is quite easy-- you can get a functional web server in like 10 lines of code.
As for what framework would be good to use for the actual calculations, unfortunately I don’t have any recommendations. Generally I find that JS has enough by default to do decently complex grouping, summarizing, subsetting, calculating, etc. operations. You’ll probably want to use the “new” (now pretty old) array methods Map and Reduce, and new stuff like groupBy could be helpful. If you have any specific questions I should be able to answer them.
I think that’s a nice hot goal to have, but you’re shooting yourself in the foot by aiming so high (pardon the tortured metaphor). Start with the basics of webdev and work your way up.
Like I’m a senior dev, and for years I thought I understood frontend. Finally, I had to reckon that I did not, and took a course on how to build a web app using React on Typescript + various popular libraries (YMMV).
Yeah a lot of it was boring or stuff I mostly knew anyway, but actually sitting down and going to school on it, like with pencil and paper, was a big help. So now I can actually contribute to FE/web dev. And all those little things I feel I should know are either known, or knowable because now I understand what to search for.
Bruh, I’m talking about a crud app. Possibly running on the shiny framework. It’s not going to be trivial.
Oh, okay. Still more doable than you might think, but of course not trivial. Good luck!

Apologies for the wait!

Yeah. I’m like 46 now, and this just feeds into my “fuck it” mentality. Thanks for the input, seriously, that is not sarcasm.
Have you tried discussing this with ChatGPT/Claude/Perplexity? I’ve found it extremely helpful for getting started, and exploring different options.
Imma be blunt. Maybe your attitude is contributing to the ‘Several degrees of idiocy at work’
Dudes tryin to be helpful with beginner tips and you jump down his throat. The irony of you saying crud isn’t trivial 😂
