PDF Tamper Detection in Next.js: App Router Integration Guide

Originally published at htpbe.tech. The version on htpbe.tech stays in sync with the latest detection algorithm — refer to it for the canonical text. A Next.js app that accepts document uploads has a specific problem: the file never touches a long-lived server you control. It lands in a serverless function with a body-size ceiling, runs for a few hundred milliseconds, and disappears. If a user submits a bank statement, a payslip, or an invoice, your App Router handler has one chance to decide wh

How Abstract Syntax Trees (ASTs) Power Modern Code Transformations

Understanding the Complexity of Migration When we talk about moving from a Client-Side Rendered (CSR) setup like Vite to a framework like Next.js, we aren't just changing a few script tags. We are shifting paradigms. You are moving from react-router-dom to File-based Routing, and potentially from useEffect data fetching to Server Components or getStaticProps. Doing this manually is error-prone. Regex-based find-and-replace is notoriously dangerous for code refactoring because it lacks context. I

Virtualizing Dynamic Lists and Responsive Grids Without Offset Tables or Size Estimation

In this article, I'd like to share my approach to virtualizing lists with items of unknown height. Most existing virtualization libraries solve this problem by estimating item sizes, measuring the rendered elements, and continuously correcting those estimates as more information becomes available. Here I'd like to describe a method that takes a different direction. Instead of relying on accumulated item offsets, it maps item indices directly to the scrollbar position. This makes it possible to d

How to Refactor a Laravel Project Without Breaking Everything

Every Laravel project starts clean. Then the project grows. Controllers become larger, business logic spreads across the application, duplicate code appears, and even simple changes become risky. The biggest mistake many developers make is trying to rewrite everything at once. Instead, successful Laravel refactoring is about making small, controlled improvements while keeping the application stable. Keep controllers thin. Move business logic into service classes. Refactor incrementally instead o

What Is the Most Effective Rat Control Method? A Complete Guide

Rats are among the most resilient and adaptable pests on the planet. They breed quickly, squeeze through gaps as small as a coin, and can survive on almost anything. If you've ever dealt with a rat problem at home or in a commercial space, you already know that a single trap or one bag of poison rarely solves the issue for good. rat control comes from combining several methods into one strategy, rather than relying on just one trick. Below is a breakdown of the methods that pest control professi

Stop Paying Full Price: The Claude Code Agentic Flow Tutorial for Running Gemini, OpenRouter, and 300+ Cheap Models

Your Claude Code bill just made you flinch. Here's the fix. Here's the good news: you don't have to choose between Claude Code's agentic harness and your wallet. Claude Code is actually two separate things bolted together: a battle-tested agent loop (the part that reads files, runs terminal commands, calls tools, and manages sub-agents) and a backend model (the part that does the actual thinking). You can keep the harness you love and swap the backend for something dramatically cheaper Gemini Fl

Markdown for Agents, Self-Hosted: One Symfony Subscriber Instead of a Cloudflare Plan

A growing share of my side project's traffic isn't people. Forgemage is a marketplace where Dofus players find smithmages, and since AI-assisted search took off, some of its "visitors" are LLMs fetching a page to answer somebody's question. They get what browsers get: 59 KB of HTML for roughly a thousand words of actual content. The rest is Bootstrap classes, SVG icons, a cookie banner, and a footer the agent will dutifully tokenize and ignore. In February, Cloudflare shipped a feature called Ma
