Building a Custom Home Casting App with Rust and React

Have you ever wanted a simple, lightweight way to cast videos from your phone to your smart TV without relying on third-party apps or dealing with complex Chromecast/DLNA setups? In this article, I am going to show you how I built "Home Cast" – a fully self-hosted video casting application using a Rust backend and a sleek React frontend. The ArchitectureThe system consists of two main parts:The Server (Rust/Axum): A fast, concurrent backend that handles video uploads via multipart forms and

How I Added a Razorpay Paywall to My React App in 10 Minutes

Every time I built a new app, I copy-pasted the same paywall code.The Razorpay subscription logic. The gate component that blocks UI for free users. The pricing modal with the monthly/yearly toggle. The usePro hook that checks localStorage and optionally pings a verification endpoint.Same code. Every app. Every time.So I extracted it all into react-premium-gate — a zero-dependency React library with three exports that handle the entire Razorpay subscription flow. What's in the boxThree thin

I was rewriting the same database plumbing in every Electron app, so I built NookDB

Every Electron app I built reached the same fork: "okay, now add a database." And every time, that one sentence quietly turned into three separate jobs.A typed schema and query layer, so I wasn't writing stringly-typed SQL and casting rows by hand.IPC plumbing to get the database — which lives in the main process — into the renderer. ipcMain.handle for every operation, a preload bridge, serialization on both ends.Reactivity, some event bus so the UI re-rendered when the data underneath it change

Why I’m building a media CDN to fix the "Math Equation" URL problem

As developers, we’ve all been there. You’re shipping a feature, you need to deliver images, and you reach for the standard industry "media cloud."Everything is great until you look at the source code of your own application. Your clean, semantic project structure is now littered with URLs that look like this:res.cloudinary.com/hq34/image/upload/v158/w_300,c_fill,g_auto,f_webp/folder/product_id_982.jpgThat isn't a URL; it’s a math equation. 🤯The Problem: Bloat and ComplexityExisting media infrast

React Server Components: a practical guide for fullstack developers

React Server Components: a practical guide for fullstack developersReact Server Components represent a fundamental shift in how React applications render. Components can run on the server, sending only the HTML result to the client. This reduces the JavaScript bundle size, improves initial load time, and gives server-side data access without APIs.Server Components are the default in Next.js App Router. They run exclusively on the server, have direct access to databases and file systems, an

Why I Built a Privacy-First JSON Formatter After the jsonformatter.org Data Leak

In November 2025, security researchers dropped a bombshell: jsonformatter.org and codebeautify.org had been silently leaking user data for years. Over 80,000 code snippets — including AWS keys, GitHub tokens, database passwords, and banking details — were publicly accessible through an unprotected "Recent Links" feature. Attackers were actively scraping the data within 48 hours of the researchers planting canary tokens.I was one of the developers who had used these tools. And I had no idea my da

Running a Crypto Trading Bot on a VPS: The Complete 2026 Guide

Running a Crypto Trading Bot on a $5 VPS: The Complete 2026 GuideI spent $47.99 on cloud hosting last year. Then I discovered I could run my entire crypto trading operation on a VPS that costs less than my daily coffee. Here's exactly how I did it — and why you should too. The Problem with Cloud HostingWhen I first built my trading bot, I hosted it on AWS. Fine for prototyping. Terrible for a side project that needs to run 24/7. My bill looked like this:$35+/month for a t3.medium$15+/

Practical Notes on M3U8 and HLS Playback Issues

I have been collecting some practical notes around M3U8 and HLS playback recently.At first, this topic may sound simple: put an M3U8 URL into a player and play the video.But in real projects, M3U8 playback is often not that simple. When a video does not play, the problem is not always the player. It can also be the playlist, media segments, browser support, server headers, CORS, HTTPS, or codec compatibility.This post is a short collection of practical things I think are useful when working with

10 Playwright Tips That Will Change How You Write Tests

I remember the first week I seriously used Playwright.I was migrating a 200-test WDIO suite. I thought it would take two weeks. It took four days. Not because Playwright is magic — but because once you understand how it actually thinks, everything clicks into place faster than any other tool I have used.But I also made a lot of mistakes early on. I wrote tests the old way — the Selenium way — inside a tool that was designed for something better.These are the 10 tips that changed how I write Play
