# Why We Abandoned Next.js + Other Developer Confessions This Week

_Sorry for the radio silence – I've been busy building._

I know I missed sending out last week's newsletter, but I had a good reason – I was heads down launching my very first product with plans to be profitable! Say hello to [Eventson](https://www.eventson.co/), a platform I've been pouring my heart and soul into. More details on that journey soon!

## **🎟️ AI Crush Conference – Your Early Support Deserves a Reward!**

I want to sincerely thank all of you for your incredible interest and support as we've been getting AI Crush off the ground. It's been my first conference, and I won't lie – it's been stressful! But seeing your enthusiasm has made it all worthwhile.

After weeks of stress, late nights, and endless emails, I'm thrilled to announce that tickets for AI Crush are officially on sale! The CFP closes tonight, and over the next two weeks, we'll be announcing our incredible lineup of speakers and the full agenda.

**Codú community early discount**: Use code _EARLYCRUSH_ for 30% off your ticket! This discount is only available for the next 12 days, so don't wait too long.

This is the absolute best price we will release so if you are going to buy I recommend doing it now!

I'll be sending a separate reminder tomorrow as well for the first time so apologies if it's too much, but I want to make sure that folks get this offer while they can.

Checkout the [website here](https://www.crushconf.com/) for the current speaker list and you can buy tickets on Eventson [here](https://www.eventson.co/219e4b9a-228e-4b58-878b-6c77fda837c0).

## **This Week's Picks**

📝 [**Using AI in the Browser for Typo Rewriting** (8 min)](https://www.raymondcamden.com/2025/02/27/using-ai-in-the-browser-for-typo-rewriting)Chrome’s new built-in AI APIs can now fix typos in user input. This post explores the Prompt API (which improves clarity but slightly alters text) and the Rewriter API (which stays true to the original but isn’t perfect). Includes hands-on code examples!

⚡️ [**Why We Ditched Next.js and Never Looked Back** (8 min)](https://northflank.com/blog/why-we-ditched-next-js-and-never-looked-back)Northflank dropped Next.js after facing SEO issues, performance slowdowns at scale, and frustrating debugging. They switched to a custom React SSR setup with Express. Interesting read for anyone reconsidering their frontend stack.

🎮 [**I Struggled with Git, So I’m Making a Game to Spare Others the Pain** (15 min)](https://initialcommit.com/blog/im-making-a-git-game)After battling Git’s learning curve, this dev built **Git-Sim** to visualize commands. But they didn’t stop there—now they’re creating **Devlands**, a voxel-based game where you explore Git concepts interactively. A fresh take on learning version control!

🎨 [**Knowing CSS Is Mastery in Frontend Development** (4 min)](https://helloanselm.com/writings/knowing-css-is-mastery-to-frontend-development)A solid grasp of CSS is key to frontend mastery. Instead of overcomplicating things with JavaScript, this article argues that native CSS solutions are often cleaner, faster, and more maintainable.

💨 [**They Just Tagged Tailwind CSS v4.0** (13 min)](https://tailwindcss.com/blog/tailwindcss-v4)Tailwind v4 brings major performance boosts, a revamped configuration system, and better support for modern web features. If you use Tailwind, this is a must-read.

🤖 [**A New AI Worry: Young Coders No Longer Know How Their Code Works** (3 min)](https://www.inc.com/kit-eaton/a-new-ai-worry-many-young-coders-no-longer-know-how-their-code-really-works/91151569)Are AI coding assistants making devs too reliant? New research suggests younger engineers might be losing critical problem-solving skills by relying on AI-generated code without fully understanding it.

🔗 [**Introducing the Model Context Protocol** (3 min)](https://www.anthropic.com/news/model-context-protocol)Anthropic open-sourced the **Model Context Protocol (MCP)**, a standard that helps AI assistants connect to live business tools, dev environments, and content repositories. If you're interested in making AI responses more context-aware, this is worth exploring.

🛠️ [**Agents.json: Translate OpenAPI into LLM Tools** (Repo)](https://github.com/wild-card-ai/agents-json)**Agents.json** is a new spec that brings structure to AI-agent interactions using OpenAPI. If you're working on AI-driven workflows, this could be a game-changer.

📡 [**The Differences Between WebSocket and Socket.IO** (4 min)](https://jsdev.space/websocket-socketio)WebSockets and Socket.IO both power real-time web applications, but they work in different ways. This guide explains when to use each, their strengths and weaknesses, and how they fit into modern web development.

## **Dublin Event Tomorrow**

Join us this Wednesday, March 5th at 6:00 PM for an evening of tech talks, free food, drinks, and networking with fellow developers in Dublin!

**TWO EXCITING TALKS**:

1️⃣ **"Async Serverless Communication with MQTT"** by Brendan Scullion Learn how asynchronous communication enhances serverless websites, enabling efficient multitasking and real-time notifications. Brendan will share insights on their decision to adopt MQTT and AWS IoT Core for all async communications.

2️⃣ **"Agents Without the Fluff: What Actually Works in Production"** by me, Cut through the AI agent hype and discover practical, real-world applications. Learn about different types of agents, their capabilities, and how to build and deploy them effectively in production.

Come hungry for knowledge (and pizza)! It's the perfect way to level up your coding skills while having fun with other developers.

🔗 **RSVP HERE**: [https://www.meetup.com/codu-community/events/306456598/](https://www.meetup.com/codu-community/events/306456598/)

See you there! 👋
