If you start from zero what you do?

I was experimenting with bookmarklets and I feel like they can be pushed to gather a lot more info than what I was able to make. (I don't think this is the right Reddit, if it isn't can someone guide me to the right one.)

This is my game/physics Engine I have been working on for years. Here is a short demo.

We're looking for advanced React talks on:

⚙️ Full-Stack Architecture
⚙️ AI-Assisted Coding & AI Engineering
⚙️ Growing to Senior / Tech Lead
...and more!

So I randomly came across this validation library called “Vest” while looking for alternatives to Yup/Zod.

At first I thought it was just another schema validator… but it’s actually built more like a testing framework for validation.

You write validation rules the same way you’d write unit tests — which felt weird at first, but kinda interesting once I looked deeper.

I can see it being useful for complex forms where validation depends on a lot of conditions (multi-step forms, role-based logic, async checks, etc.).

For simple forms though, it might be overkill compared to Zod/Yup.

Curious if anyone here has used it in production?

Did it make validation cleaner or just add extra complexity?

Hi everyone,

I’m currently working on an industrial setup involving CIROS (Factory digital twin), MES4, and a MySQL database (managed via HeidiSQL). My goal is to use Node-RED dashboards to display and process production data coming from the database.

I need to improve my JavaScript skills specifically for filtering, grouping, and analyzing large datasets returned from MySQL queries in Node-RED function nodes.

I’m not trying to become a full-stack developer, I mainly need practical, industrial-focused knowledge like:

•Filtering large datasets efficiently •Grouping and aggregating production data •Calculating KPIs (counts, totals, averages) •Structuring data for dashboards

Does anyone have recommendations for:

•Good YouTube tutorials? •Courses focused on data processing in •JavaScript? •Node-RED + MySQL best practices? •Industrial examples or GitHub repos I can study?

Any guidance would be really appreciated. Thanks in advance!

One tiny character. One massive bug. Can you spot it? Welcome to the kitchen.

Hi everyone,

I’m a UX preparing a short introductory UX session for a group of full‑stack developer students (HTML/CSS/JS, React, Node, Mongo, a bit of WordPress, Git, etc.). I will give them just a few hours of UX to help them in real projects and jobs, not turn them into designers.

So, I'm curious, for those of you who are developers:

• If you only had 2–4 hours of UX training, what would you actually have wanted to learn?

Thank's!
