How modern browsers work
Note: For those eager to dive deep into how browsers work, an excellent resource is Browser Engineering by Pavel Panchekha and Chris Harrelson (available at browser.engineering). Please do check it out. This article is an overview of how browsers work. Web developers often treat the browser as a black box that magically transforms HTML, CSS, and JavaScript into interactive web applications. In tru
Web Design System: Migrating Web Components To React | Mercari Engineering
This post is for Day 8 of Mercari Advent Calendar 2022, brought to you by Williams Kwan from Mercari Core team and Faisal Rahman from the Mercari Architect team. Intro Mercari internal design systems power the UI in Mercari web apps. It allows Frontend engineers to implement UI changes quickly by providing UI building blocks. The design system is currently built using Web Components but we are in
With pen and paper, anyone can write a journal entry, draw a diagram, perform a calculation, or sketch a cartoon. Digital tablets like the iPad or reMarkable can adapt pen and paper into the world of digital media. In doing so, they trade away some of paper’s advantages like cheapness and tangibility. In exchange, we get new computational powers like nondestructive editing and ease of transmission
Skills are custom instructions that extend Claude's capabilities for specific tasks or domains. When you create a skill via a SKILL.md file, you're teaching Claude how to handle specific scenarios more effectively. The power of skills lies in their ability to encode institutional knowledge, standardize outputs, and handle complex multi-step workflows that would otherwise require repeated explanati

An introduction to WebAssembly for JavaScript Developers
If you transmit a number whereas an integer encoded on 64 bits is expected you will get an exception: let run = async () => { try { let bytecode = await fetch("add/add.wasm"); let wasm = await WebAssembly.instantiateStreaming(bytecode); console.log(wasm.instance.exports.addInt64(1,2)); } catch(e) { console.error(e); } }; > run().then(); TypeError: wasm function signature contains illegal type Call

Is Prisma ORM an ORM? | What is an ORM? | Prisma Documentation
To answer the question briefly: Yes, Prisma ORM is a new kind of ORM that fundamentally differs from traditional ORMs and doesn't suffer from many of the problems commonly associated with these. Traditional ORMs provide an object-oriented way for working with relational databases by mapping tables to model classes in your programming language. This approach leads to many problems that are caused b
Hypershell: A Type-Level DSL for Shell-Scripting in Rust | Context-Generic Programming
Discuss on Reddit, Lobsters, and Hacker News. Summary I am thrilled to introduce Hypershell, a modular, type-level domain-specific language (DSL) for writing shell-script-like programs in Rust. Hypershell is powered by context-generic programming (CGP), which makes it possible for users to extend or modify both the language syntax and semantics.

MCP Apps - Bringing UI Capabilities To MCP Clients
Today, we’re announcing that MCP Apps are now live as an official MCP extension. Tools can now return interactive UI components that render directly in the conversation: dashboards, forms, visualizations, multi-step workflows, and more. This is the first official MCP extension, and it’s ready for production. We proposed MCP Apps last November, building on the amazing work of MCP-UI and the OpenAI

What's coming next for ESLint - ESLint - Pluggable JavaScript Linter
When we released ESLint v9.0.0 in April, it was the first major release in 30 months and formally introduced the new configuration system. ESLint v9.0.0 also made some rule API changes to prepare the core for what’s coming next. After the release, we spent a lot of time creating compatibility utilities, a configuration migration tool, and a rule API transform utility to help the ecosystem move to
Bringing Javascript to WebAssembly for Shopify Functions - Shopify
Bringing Javascript to WebAssembly for Shopify FunctionsWhile we’re working on getting our Shopify Functions infrastructure ready for the public beta, we thought we’d use this opportunity to shine some light on how we brought JavaScript to WebAssembly, how we made everything fit within our very tight Shopify Function constraints, and what our plans for the future look like.

At Stripe, our product docs are designed to feel like an application rather than a traditional user manual. For example, we incorporate a user's own API test key into code samples, making it possible to copy and paste code that seamlessly works with the user's own account. We have client-side interactivity, like checklists and collapsible sections. We tailor the content to the individual user, con

Why is WebAssembly a second-class language on the web? – Mozilla Hacks - the Web developer blog
This post is an expanded version of a presentation I gave at the 2025 WebAssembly CG meeting in Munich. WebAssembly has come a long way since its first release in 2017. The first version of WebAssembly was already a great fit for low-level languages like C and C++, and immediately enabled many new kinds of applications to efficiently target the web. Since then, the WebAssembly CG has dramatically
Introduction JavaScript Object Notation (JSON) is a simple data interchange format. Almost 15 years ago, we wrote about support for JSON in Go, which introduced the ability to serialize and deserialize Go types to and from JSON data. Since then, JSON has become the most popular data format used on the Internet. It is widely read and written by Go programs, and encoding/json now ranks as the 5th mo
Toggle dark mode What follows is a brain dump of everything I know about compiling Rust to WebAssembly. Enjoy. Some time ago, I wrote a blog post on how to compile C to WebAssembly without Emscripten, i.e. without the default tool that makes that process easy. In Rust, the tool that makes WebAssembly easy is called wasm-bindgen, and we are going to ditch it! At the same time, Rust is a bit differe

Weird Lexical Syntax
I just learned 42 programming languages this month to build a new syntax highlighter for llamafile. I feel like I'm up to my eyeballs in programming languages right now.

The languages I decided to support are Ada, Assembly, BASIC, C, C#, C++, COBOL, CSS, D, FORTH, FORTRAN, Go, Haskell, HTML, Java,
What Makes Rust Unique? Why is UI in Rust So Hard? Functional UI to the Rescue If you’ve read Hacker News recently, it’s hard to not think that Rust is the future: it’s being used in the Linux kernel and in the Android OS, by AWS for critical infrastructure, and in ChromeOS and Firefox. However, as wonderful as Rust is–it has yet to take off as a general language for building UI. In 2019, “GUI” wa

Introduction Java Naming and Directory Interface (JNDI) is a Java API that allows clients to discover and look up data and objects via a name. These objects can be stored in different naming or directory services, such as Remote Method Invocation (RMI), Common Object Request Broker Architecture (CORBA), Lightweight Directory Access Protocol (LDAP), or Domain Name Service (DNS). In other words, JND
Today we’re excited to announce the release of TypeScript 5.5! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi

Write OpenAPI with TypeSpec
I've spent the last few years at Microsoft working on an API definition language called TypeSpec. It's essentially a super flexible protocol-agnostic DSL for describing API shapes. You can try it in your browser at the TypeSpec playground. Many things about it are exciting, but I want to talk about one thing in particular: why TypeSpec is the best way to write OpenAPI. OpenAPI: the good and the no

The many, many, many JavaScript runtimes of the last decade
This last decade has seen an inundation of new JavaScript runtimes (and engines in equal measure), enabling us to run JavaScript in all manner of contexts with precise fitness for task.

In this article, we'll explore what's driving this diversity, and why no one runtime or en
