The query_one() method throughout the Textual documentation allows users to retrieve a single widget that matches a CSS selector or a widget type. You can pass in up to two parameters to query_one(), which are the CSS selector and the widget type, or both at the same time.

Events are essential inputs to modern front-end systems. But when we mistake reactions for architecture, complexity quietly multiplies. Over time, many front-end architectures have come to resemble chains of reactions rather than models of structure. The result is systems that are expressive, but increasingly difficult to reason about.

The project behind this post is intentionally a bit over-engineered - in the "let's see what breaks when things grow" sense. That's by design. While a simple recipe example could easily be modelled with plain strings and numbers, cookbook explores more advanced, real-world concerns: extensibility, customisation, validation, and precise handling of numeric values, including floating-point quantities. The recipe domain is just a familiar, low-stakes vehicle for discussing these deeper ideas.

This same sense of uncertainty can be triggered in software products. Many digital experiences consist of background tasks, file imports, system updates, and other long-running processes that run quietly and invisibly, leaving users with no indications of progress or feedback. The user initiates an action, like a sync, a publish, or a bulk update, and is responsible for the outcome, while the system does all the work out of sight.

Hi everyone! This week, we saw a lot of activity on X about the new AI skills system. Personally, what excited me most is the new Firefox release that unlocks interesting things for React developers. The React Native ecosystem is also super active, with many interesting releases. And I'm sure Expo 55 beta will drop just after we send our email 😅, so make sure to check their blog because it's coming soon. Don't miss the next email! As always, thanks for supporting us on your favorite platform:

This weekend I had some fun building a little Astro site for RSS aggregation. It works by the individual user defining a set of feeds they care about and works with a server-side Astro route to handle getting and parsing the feeds. Here's a quick example. On hitting the site, it notices you haven't defined any feeds and prompts you to do so:

Modern web applications are no longer just "sites." They are long-lived, highly interactive systems that span multiple runtimes, global content delivery networks, edge caches, background workers, and increasingly complex data pipelines. They are expected to load instantly, remain responsive under poor network conditions, and degrade gracefully when something goes wrong.

Over the past decade, software development has undergone a massive transformation due to continuous innovations in tools, processors and novel architectures. In the past, most applications were monoliths and then shifted to microservices, and now we find ourselves embracing composability - a paradigm that prioritizes modular, reusable, and flexible software design. Instead of writing separate, tightly coupled applications, developers now compose software using reusable business capabilities that can be plugged into multiple projects. This enables greater scalability, maintainability, and collaboration across teams and organizations. At the heart of this movement is Bit Harmony, a framework designed to make composability a first-class citizen in modern web development.

JSR offers a modern, TypeScript-first and cross-platform-compatible registry, integrated into Deno, Deno's developers said. For Node.js and NPM compatibility, Deno 1.42 offers numerous improvements. The async_hooks module now supports the EventEmitterAsyncResource and AsyncLocalStorage.enterWith APIs. The crypto module adds getRandomValues(), subtle, getCipherInfo(), publicKey(), and createPublicKey() APIs, along with support for more curves in multiple APIs. The worker_threads module received a major overhaul.
