I’ve been building a side project to work through headless WordPress properly – Next 16 on the Pages Router, WordPress serving content over the REST API. Every page rendered correctly. Nothing was broken. And it was still shipping several seconds of avoidable wait on the paths a real reader would take. That combination is the… Continue reading Headless WordPress Performance: 3 Next.js Bottlenecks to Fix
Mitigating XSS Attacks in WordPress: A Practical Guide for Owner-Developers
Cross-site scripting (XSS) remains one of the most common vulnerabilities affecting WordPress sites, largely because WordPress’s flexibility – themes, plugins, user-submitted content, custom fields – creates so many places where untrusted data can slip into a page and execute as code in a visitor’s browser. An attacker who successfully injects a script can steal session… Continue reading Mitigating XSS Attacks in WordPress: A Practical Guide for Owner-Developers
Validation, Sanitization, and Safe Queries: The Three Layers That Actually Stop SQL Injection
Most developers can define SQL injection. Far fewer can say, precisely, which line of their code is the one preventing it. That gap matters. SQL injection has been on the OWASP Top 10 since the list existed, and it survives not because the fix is hard but because the fix is easy to believe you’ve… Continue reading Validation, Sanitization, and Safe Queries: The Three Layers That Actually Stop SQL Injection
The silent bug that turned a fast page into a slow one
A bug on the homepage surfaced recently – the kind that’s easy to write by accident and easy to miss in review: the page pre-rendered its data at build time, then threw that data away and fetched it again in the browser. This post walks through what the bug looked like, why it hurts performance,… Continue reading The silent bug that turned a fast page into a slow one
Optimize WP_Query Performance: Skipping Meta Cache Priming the Right Way
If you’ve profiled a WordPress archive page with Query Monitor, you’ve probably seen this pattern without knowing what it was: Two queries, back to back, for the exact same batch of post IDs. One fetches the posts. The second – often slower, despite doing “less” – fetches metadata nobody asked for. That second query is… Continue reading Optimize WP_Query Performance: Skipping Meta Cache Priming the Right Way
Jest Testing Best Practices: Implementation Tests vs Behavior Tests Explained
When you write a Jest test for a Gutenberg block’s save function, there are usually two paths you can take: test what was called, or test what got rendered. They look similar on the surface, but they lead to very different test suites. Approach 1: Testing Implementation Details This test checks that useBlockProps.save was called… Continue reading Jest Testing Best Practices: Implementation Tests vs Behavior Tests Explained
Enterprise WordPress Performance: Smarter postmeta Key Design
Every WordPress developer has written a WP_Query with a meta_query argument. It feels natural. But at enterprise scale — hundreds of thousands of posts, millions of rows in wp_postmeta — those queries become some of the heaviest load your database carries. The good news: a significant slice of that cost is avoidable with a shift… Continue reading Enterprise WordPress Performance: Smarter postmeta Key Design
WordPress Performance Optimization: 15 Hooks Every Enterprise Developer Should Know
If you’ve worked on enterprise WordPress for any length of time, you already know the truth: performance problems rarely come from one big bottleneck. They come from a hundred small ones stacked on top of each other — an unindexed meta query here, a Heartbeat request every 15 seconds there, an unnecessary found_posts count on… Continue reading WordPress Performance Optimization: 15 Hooks Every Enterprise Developer Should Know
