Chromium will not page-break inside a column flexbox

I build Resumarc, a resume builder. Every template in itis a single React component that draws three things: the card in the gallery, thelive preview in the editor, and the printed PDF. There is no separate printstylesheet. What you arrange on screen is what comes out of the file, because itis literally the same component rendered at a different size.That constraint is the good part of the design and it is also how I found theworst bug I have shipped. The symptomWhile testing exports before

Optimizing User Idle Detection in React

The Challenge of Responsive Idle TrackingTracking user inactivity is essential for modern web applications—whether it's auto-saving drafts, timing out sessions, or pausing resource-heavy animations. However, naïve implementations of activity listeners often lead to performance bottlenecks due to excessive event firing.In the latest update to react-hook-lab, I have refined the useIdle hook to implement dynamic throttling, ensuring that your state updates remain performant even during high-f

Scaling Socket.IO Horizontally: Why Your Real-Time Architecture Breaks Beyond a Single Process

Part 1: The Illusion of Single-Server SimplicityWebSockets are the foundation of modern interactive web apps. Whether you are synchronizing live cursor movements in a collaborative canvas, streaming inference progress from a background AI job, pushing real-time order tracking updates, or delivering financial ticks, persistent full-duplex TCP connections make instant client updates trivial.During early development, building these features with Socket.IO in Node.js feels seamless. You initia

GiggleGigs: A Job Board That Actually Uses AI Where It Helps

Most job boards are glorified spreadsheets with a search bar. GiggleGigs isn't. It's a two-sided marketplace — "Find Work. Hire Talent." — built to close the gap between "I posted a job" and "I hired someone good," using AI at exactly the three points where it saves real time: writing the posting, writing the application, and screening the results.Here's what's actually under the hood, and why it's worth a look. The Problem It SolvesJob boards fail in a predictable way: employers post vague

Create calendar invites in Node.js that update and cancel cleanly

Create calendar invites in Node.js that update and cancel cleanlySend .ics calendar invites from Node.js with Nodemailer, then move and cancel them without leaving duplicate events in anyone's calendar.Sending one calendar invite is easy. The bugs show up on the second email.You move the meeting by an hour and every attendee now has two events. You cancel it and the event stays on everyone's calendar. You send it from Gmail and the Accept and Decline buttons never appear.All three come from the

What I Wish Someone Told Me Before I Learned to Code at 25

I didn't grow up dreaming of being a developer. At 25, I had two degrees, zero job offers, and a growing suspicion that the plan I'd spent years building wasn't going to work.I'm writing this for anyone in the DEV community who came to programming late, sideways, or out of necessity rather than childhood passion — because I think there are more of us than the "I wrote my first line of code at age 8" stories would suggest.The trap I didn't see comingBefore I get to the code part, I have to talk a

How I Detect JSON, Base64, URLs, and Timestamps Without AI

Format detection sounds simple until the inputs overlap.A numeric string might be a Unix timestamp, an identifier, or valid-looking Base64. A normal word can use only Base64 characters. JSON often arrives wrapped in Markdown fences or surrounded by an LLM explanation.For QuickTiny Smart Actions, I wanted the browser to suggest the right tool without uploading the pasted value or calling an AI model. The detection orderThe order is intentional:Valid JSON objects or arraysFenced, wrapped, or

The Grand Unifying Architecture of Frontend

I used to joke that the history of frontend development could be retraced by following the argument of who owned the state. And the truth is both sides have gone back and forth on this over the years. We started on the document web where state was on the server. Then we added JavaScript and Applets where we could have stateful things in the client. But developers at the time didn't like either much and tried to wire state across both sides in their server languages and we got ASP.NET and the lik

The page break you see is a guess: what I learned building an embeddable report designer

Sooner or later, every serious business application needs to produce documents for its customers: statements, client reviews, factsheets, invoices, certificates. Then someone asks whether customers can design their own. That's usually when a team starts building a report designer, under deadline pressure and without really meaning to.After twenty years of building business software, I decided to build the one I kept wishing existed, and to do it properly. It's called BroadPaper. It's an embeddab
