An MCP server is not a new API. It is a thin layer over the one you already have
Somewhere in the last year, "do we need an MCP server?" joined the list of questions that arrive in a brief before anyone has said what the thing is for. It is usually framed as MCP vs API, as though the Model Context Protocol were a newer kind of AP...

Your Next.js redirect() Silently Does Nothing Because It's Inside a try/catch
A user fills in your form and clicks "Create post". The post is saved in the database. And the page shows "Could not create post". They try again. Now there are two posts. Nothing is wrong with your database. Your error handling caught something it...

You Deleted the .env File From Git. Your Secrets Are Still Public.
You notice it during a code review: .env is in the repository. Your stomach drops. You run git rm .env, commit with the message "remove env file", push, and feel the relief of a problem solved. It is not solved. The file is gone from your latest com...

You Upgraded to Next.js 15 and Your Site Got Slower. The Caching Defaults Flipped
You upgrade from Next.js 14 to 15. The app compiles, the tests pass, nothing visibly breaks. A week later your database bill is higher, your pages feel slower, and your Time to First Byte graph has a step in it that lines up exactly with the deploy. ...

"'use client' Doesn't Turn Your Whole App Into a Client Component (The Children Trick Nobody Explain
You need a theme provider, so you create a file, add 'use client' at the top, and wrap your app in it. Then a nagging thought arrives: "I just wrapped my entire layout in a client component. Did I turn the whole app into client-side React?" Most de...

How to Protect a Next.js App with a WAF Before You Change DNS
A Next.js app is still a web application that speaks HTTP. That is the only placement fact you need before you look for a framework plugin. The SafeLine documents used here do not describe a Next.js SDK, App Router hook, or hosting-platform add-on. T...

How to Protect a Next.js App When No Framework Plugin Exists
If you are asking how to protect a Next.js app with a WAF, start by rejecting the idea of a hidden framework connector. The SafeLine documents supplied here never mention Next.js, React Server Components, a middleware file, or a platform add-on. They...

Your Next.js Dates Are Wrong for Half Your Users (and the Hydration Warning Is Only the Start)
You format a date in a component. It looks right on your laptop. Then a user in another country opens the page and either sees a console full of hydration errors, or worse, sees nothing wrong at all and reads the wrong time. I live in a timezone tha...

Developer Weekly Briefing — October 30, 2026
Security dominated this week, but not in the usual way. Two active campaigns turned GitHub configuration files into attack surfaces. Researchers demonstrated that the built-in browsers inside AI coding tools can read your SSH keys. And at Oracle AI ...

Fix: useSearchParams() Should Be Wrapped in a Suspense Boundary (and Why It Only Breaks at Build
You add a small search box to your navbar. It reads the query string, so you reach for useSearchParams. Everything works in next dev. You push, the deploy fails, and the build log says: useSearchParams should be wrapped in a suspense boundary at pag...

Your Server Action Error Messages Vanish in Production, and Throwing Is the Wrong Tool
Here is a bug report you will eventually get: "The signup form told me what was wrong on your machine, but on the live site it just says something went wrong." Nothing is broken. Next.js is doing this on purpose. But the code that triggers it looks ...

Why Your Tailwind Classes Work in Development and Silently Vanish in Production
Almost every Tailwind developer hits this exact bug once, usually right after a deploy, and the confusing part is that nothing about it looks wrong in the code, nothing throws an error, and it worked completely fine five minutes earlier on the same m...

Vercel Was Too Expensive, So I Migrated My Next.js App to Cloudflare Workers
I recently moved production traffic for Galaxy Movies1, my Next.js movie/TV discovery site, off Vercel and onto Cloudflare Workers. Nothing against Vercel. Vercel is a great platform, and the app ran happily there for a long time. But I was paying fo...

Your Next.js Page Might Be Caching One User's Data and Serving It to Everyone Else
This is the kind of bug that goes from "works perfectly in every test" to "actively leaking one customer's data to another customer" without a single code change in between, purely because of how caching and personalization interact in a way that isn...

Your Mongoose pre('save') Hook Is Being Silently Skipped by Half Your Update Calls
This is one of the more consequential Mongoose gotchas because of exactly what tends to live inside a pre'save' hook, password hashing, slug generation, validation logic, and exactly which methods silently bypass it without ever telling you. The Set...

Your NextAuth callbackUrl Might Be an Open Redirect Waiting to Happen
Redirecting a user back to the page they were trying to reach after they log in is good, expected UX. Nobody wants to log in and land back on the homepage when they were actually trying to read a specific article or check out a specific product. The ...

Your Next.js Middleware Matcher Config Is Probably Skipping Routes You Think It Protects
Middleware feels like the cleanest way to gate an entire section of a Next.js app behind auth, one file, one config, covering everything under a path. That confidence is exactly the problem, because the matcher config that's supposed to define "every...

You Changed a User's Role in the Database, But Their JWT Doesn't Know That Yet
You find out a user's permissions need to change right now, maybe they're being demoted from admin, maybe their account access is being revoked entirely after an incident. You update the database. The change looks instant in your admin panel. Meanwhi...

How we check every AI-generated room render before a user sees it
Image models are very good at restyling a room and quietly bad at leaving the room alone. Ask for a Japandi living room and you get beautiful furniture, and sometimes also: a window that moved, shrank, or appeared over a kitchen sink where the photo...

Your useEffect Search Bar Has a Race Condition, and It Only Shows Up When Users Type Fast
This is one of those bugs where the code looks completely reasonable, passes every manual test you'd naturally think to run, and still ships with a real defect that only shows up under a specific, very common usage pattern: someone typing faster than...
