> "I just wanted to build a simple POS system… Now my terminal has trust issues and my PC thinks it's a full-time cashier." 😅
👋 Hey there, dev fam!
Welcome to Part #1 of my dev series, where I take you behind the scenes of how I'm building a modern, beautiful, cross-platform POS system from scratch - using some of the hottest tech in the JavaScript world. 🛠️🔥
I'm calling it Ineero POS.
Because it sounds like a startup that could raise $10M… but it's just me in my room, drinking tea and fighting bugs. ☕💻
💡 Why a POS System?
Because I noticed a lot of small businesses still use clunky, outdated systems from the Windows XP era 🪦.
I thought… "Why not build a sleek, modern POS that actually feels nice to use?"
Plus, it's a great way to flex my ✌️full-stack✌️ skills - while creating something useful and sellable.
🚀 The Tech Stack - aka The Avengers of Dev Tools
Let's break it down:
🖥️ Frontend
Next.js - Pages, routing, SSR… and hot reload that gives me life 🔥
Tailwind CSS - Like having a personal designer that works for free
ShadCN/UI - Beautiful UI components straight out of a dev's dream
Framer Motion - So smooth, even your grandma will notice the animations 😎
🧠 Backend
Express.js - Our server ninja, handling APIs like a pro
MongoDB + Mongoose - Flexible, fast, and perfect for storing product data, users, sales, etc.
🖥️ Desktop App Magic
Electron - Wrap the whole thing into a desktop app. Because we fancy 💼
Electron Builder - For packaging and auto-updating (yes, it updates itself - no floppy disks here)
dotenv - Keepin' secrets like a pro hacker 😎
⚙️ Dev Tools
pnpm - Fast, light, and doesn't eat your node_modules for breakfast
dotenv-cli - Run scripts with environment variables like a boss
GitHub Releases - Because we want auto-updates like real SaaS pros
🛠️ First Steps - Setting Up the Beast
Started with a Next.js + Tailwind dashboard.
Created the Express.js backend with MongoDB connection.
Integrated Electron and made it all run locally in one command. (Which worked after only 48 hours of crying and emotionally depending on AI like it's my co-founder.)
Set up auto-updates using Electron Builder + GitHub Releases - now users can download it and it updates without manual install. Yup, like magic.
🎯 What's Next?
- - Add product management
- - Build a POS terminal UI
- - Start selling it to real businesses
- - Fix the 17 bugs I just created while writing this post

This is just Part 1. I'll be dropping more updates as I build out the entire system - including sales reports, barcode scanners, invoice printing and all that good stuff 💸
