A home for my story

For the first time, I carried thoughts that had nowhere to land. The search for a home for my articles led me not just to yet another platform, but to the idea of my own blog - built on top of the AT Protocol.

Open Social Software. npmx

We’ve just celebrated reaching 3,000 stars, made a number of major releases, and the team gave a really great presentation at atmosphereconf... But it seems I still hadn’t actually answered so many questions - just teased at the end of the previous article. I think it’s time to formulate the answers and finally gather them all in one place.

The month. npmx

npmx - a fast, modern browser for the npm registry. You've definitely heard about this project, and it’s probably got you just as excited as it has me. We've had a month of exciting and invaluable experience, and we've got some crazy plans ahead. I'm Alex, a project maintainer and one of the many who have been lucky enough to witness the formation of npmx from the front lines. This is an article reflecting on the project, warm stories, wonderful people, and, of course, a look into the future. I hope I can convey this marvelous experience and give you the opportunity to feel it with me.

Website Performance. Big Basic Checklist

A fast website is something very obvious and simple: the site loads quickly and does not freeze. “If you make people wait 3 seconds, you start losing users” is a rule that probably every web developer has heard. But this rule is only the tip of the iceberg, both when it comes to the reasons customers are lost and when it comes to real outcomes. This article is a comprehensive collection of information about performance: from the history of the first analysis tools and the reasons they appeared, to modern problems and universal ways to improve a website.

Vercel Edge — what is it and how is it

Edge runtime. One of the main functionality of Vercel — the company that developed and maintains next.js. However, its influence on the edge runtime has gone far beyond its frameworks and utilities. The edge runtime works in the recently acquired by Vercel Svelte, in nuxt, and in more than 30 other frontend frameworks. This article will focus on the edge runtime — what it is, how it is used in Vercel, what features it adds to next.js, expected changes and what solutions I made to expand these features.

Caching in next.js. Gift or Curse

The App Router significantly expands the functionality of next.js — partial pre-rendering, templates, parallel and interceptable routes, server components, and much more. However, despite all these improvements, not everyone has decided to switch to the App Router. And there are reasons for that.
