Bringing React's to vanilla JS

Sunday, June 22, 2025 Teklinks

I like React. I really do. It is the default answer for modern web development, and it is that answer for a reason. Generally when React adds a feature it is well thought through, within the React system of thinking.

LangGraph for complex workflows

Sunday, June 22, 2025 Teklinks

I may be late to the party, but LangGraph lets you build complex workflow architectures and codify them as powerful automations. Also LLMs, if you want. But you don’t have to! I always liked the idea of “flow-based” programming. PureData, DaVinci Resolve, Node Red... they all appeal to me.

Want to Be a Better Frontend Engineer? Try a Week On-Call

Sunday, June 22, 2025 Teklinks

You’re going to hate me for saying this, but I actually like being on-call. I know. I know. But hear me out. Obviously not the part where PagerDuty yanks you out of a dream with your heart pounding. But on-call taught me more about frontend quality than any bug tracker ever did.

ai agents

Friday, June 20, 2025 Teklinks

I'm using agents to write a lot of code now. Just 6 months ago it didn't really work well, so if you haven't tried in a while, this is your sign. Let me explain practically how I've been using them, where they still kind of suck, and what tools I've had success with.

My AI Skeptic Friends Are All Nuts

Friday, June 20, 2025 Teklinks

Tech execs are mandating LLM adoption. That’s bad strategy. But I get where they’re coming from. Some of the smartest people I know share a bone-deep belief that AI is a fad — the next iteration of NFT mania.

The Underestimated Power of Hot Spots and Notes in EventStorming

Friday, June 13, 2025 Teklinks

I've been facilitating the EventStorming sessions for years now, and something keeps catching my attention. While teams naturally focus on mapping out those orange event sticky notes (the backbone of any EventStorming session), they often underestimate the power of two critical elements: Hot Spots and Notes.

How Imports Work in RSC

Friday, June 13, 2025 Teklinks

React Server Components (RSC) is a programming paradigm that lets you express a client/server application as a single program spanning over two environments. Concretely, RSC extends the module system (the import and export keywords) with novel semantics that let the developer control the frontend/backend split.

Search Params Are State

Friday, June 13, 2025 Teklinks

Search params have been historically treated like second-class state. They're global, serializable, and shareable — but in most apps, they’re still hacked together with string parsing, loose conventions, and brittle utils. This works, but it’s manual and repetitive.

How we built our AI code review agent for IDEs

Thursday, June 12, 2025 Teklinks

At CodeRabbit, we recently shipped our free VS Code extension, bringing context-rich AI-powered code reviews directly into your editor. Our engineering philosophy has always been simple: we build tools that fit seamlessly into your existing workflow. While developers have told us our comprehensive PR reviews have helped them ship faster and keep more bugs from production, many also asked for IDE reviews to help check code prior to sending a pull request.

Is It JavaScript?

Thursday, June 12, 2025 Teklinks

“It’s Just JavaScript!” is probably a phrase you’ve heard before. I’ve used it myself a number of times.It gets thrown around a lot, often to imply that a particular project is approachable because it can be achieved writing the same, ubiquitous, standardized scripting language we all know and love: JavaScript.

Adopting Docs-as-Code at Pinterest

Monday, June 09, 2025 Teklinks

Technical documentation is the backbone of any successful engineering team, yet at Pinterest, it has consistently been a source of frustration. Despite using popular web-based wiki tools and experimenting with well-known alternative applications, our internal developer surveys reveal that documentation remains a top pain point.

Sunday, June 08, 2025 Teklinks

MCP rapidly enhances AI capabilities but introduces security challenges through its distributed architecture. Especially, the distributed nature of MCP requires a lot of NHIs and their secrets. Our research shows that MCP is a new source of leaks that already discloses real-world secrets.

Nine Emerging Developer Patterns for the AI Era

Sunday, June 08, 2025 Teklinks

Developers are moving past AI as just tooling and starting to treat it as a new foundation for how software gets built. Many of the core concepts we’ve taken for granted — version control, templates, documentation, even the idea of a user — are being rethought in light of agent-driven workflows.

Next.js Server Actions are public-facing API endpoints

Thursday, June 05, 2025 Teklinks

Thanks to Server Actions, developers are able to execute server-side code on user interaction, without having to create an API endpoint themselves. I’ve emphasised “themselves”, because server actions are a syntactic sugar for API endpoints, which to my surprise, is not that well-known amongst some professionals in the industry.

Human coders are still better than LLMs

Wednesday, June 04, 2025 Teklinks

This is a short story of how humans are still so much more capable of LLMs. Note that I'm not anti-AI or alike, you know it if you know me / follow me somewhere. I use LLMs routinely, like I did today, when I want to test my ideas, for code reviews, to understand if there are better approaches than what I had in mind, to explore stuff at the limit of my expertise, and so forth (I wrote a blog post about coding with LLMs almost two years..
