I Shipped an Play Store App That Updates Itself, Because There's Nothing in It to Update
com.myvitals.app, installed from the Play Store, icon and splash screen and everything, has almost no native UI. Open the source: a splash screen, an error screen, one WebView pointed at https://myvitals.co.in. That's the app.export const WEBVIEW_URL = 'https://myvitals.co.in';That string is functionally the entire product. Ship a fix to the web frontend — a normal deploy — and every installed app gets it next open. No review queue, no staged rollout, no "update available" nag. The native shell
Start Your React Rule File With State. Here Is How to Write That Section.
A friend of mine decided last spring that he was finally going to write down his coding standards so the AI would stop handing him components that looked like they came from four different projects. He opened a markdown file, typed a heading, sat there for maybe ten minutes, and then went and did something else. When I asked him about it a few weeks later the file was still open in a tab somewhere with nothing under the heading.That happens to almost everyone who tries this. "Write down your sta
How to Fix LLM Streaming Lag and React Render Storms
The LLM 'Render Storm': Why 50 Tokens/Sec Will Lag Your React AppGenerative AI is transforming how we build applications, but it has introduced a silent performance killer in frontend development: the "Render Storm." If you are building an AI-powered chat interface or a real-time document generator, you have likely encountered the challenge of streaming text. Many developers start by piping their LLM stream directly into a React state variable. It seems logical—data comes in, you update th
Making a React Video Editor Agent-Friendly with Timeline Markers and MCP
A video editor needs to remember more than cuts. It also needs to remember why a cut matters.“Start the second chapter here.” “Review this section before publishing.” “Leave a little more room at the end.” These instructions become much easier to act on when their timestamps and context live inside the project.I recently added persistent timeline markers to Timeline Studio, the open-source browser video editor I maintain, and exposed them through its CLI, MCP adapter, and Agent Skill.

React
PROPS:Props are used to pass data from a parent component to a child componentReact Props are like function arguments in JavaScript and attributes in HTML.To send props into a component, use the same syntax as HTML attributes:createRoot(document.getElementById('root')).render( <Car brand="Ford" />);The component receives the argument as a props object:function Parent(props) { return <h1>Hello, {props.name}!</h1>;}function Child() { return <Parent name="John" />;}Destru
React - BrowserRouter and useNavigate
BrowserRouter:In React, BrowserRouter is a parent component provided by the react-router-dom library that enables client-side routing in web applications. It acts as the "routing engine" by wrapping your entire application, allowing you to switch between different views or "pages" without triggering a full browser refresh. React Router DOM:react-router-dom is an npm library that enables navigation and routing in React web applications.React Router DOM is an npm package that enables yo
React - useContext
useContext:useContext is a built-in React Hook that allows components to read and subscribe to data (context) from a parent component without manually passing props down through every level.The useContext hook in React is primarily used to share global data across a component tree without having to pass props down manually through every level. This technique eliminates a common development problem known as prop drilling. Difference between Prop Drilling vs. useContext: Working:us

Tired of Expensive SEO Tools? A Simpler Approach to Keyword Research, Backlinks, Rank Tracking & Site Audits

The npm Install Script That Silently Ran Your Build
Every npm install you run executes lifecycle scripts automatically. A malicious or misconfigured postinstall hook can spawn subprocesses, write files, or exfiltrate data before your CI even notices. This is not a theoretical risk -- it is the mechanism behind most npm supply chain incidents.vlt 1.0, built by the original npm team, addresses this directly with phased installations that separate dependency resolution from script execution. Here is what that actually means for your project, and whe
