Tutorials covering programming languages, type systems, architecture, tooling, and the patterns used to build software that lasts. Each chapter is standalone, built around real examples and verified facts.
A TypeScript project needs a bundler. The compiler (tsc) can check types and emit JavaScript, but it is not optimized for producing a single file, splitting code into chunks, or handling CSS, images, and other assets. Bundlers take the output of the TypeScript compiler — or the original TypeScript source — and produce the deployable…
Vue’s reactivity system is designed to clean up after itself. When a component unmounts, its effect scope stops, its watchers are disposed, and its reactive dependencies are released. The leaks that remain are almost never Vue’s fault. They are caused by code that creates a resource outside the component’s scope—an event listener on window, a…
The previous chapter covered change detection and rendering — the work Angular does while the application is running. This chapter covers the work that happens before the application runs: downloading, parsing, and executing the JavaScript, CSS, and assets that make up the application. A fast application is not just one that renders efficiently. It is…
Dart targets the web through two distinct compilation pipelines that share a common frontend but diverge at the back end. dart2js translates Dart into JavaScript, using an SSA-based intermediate representation and a closed-world assumption to perform whole-program optimizations before emitting JavaScript that browsers can execute directly. dart2wasm translates Dart into WebAssembly, targeting the WasmGC proposal…
The CIS Docker Benchmark is a vendor-neutral hardening standard published by the Center for Internet Security, currently at version 1.6.0, with over 100 recommendations organized into seven sections covering the host, daemon, configuration files, images, runtime, operations, and Swarm . Auditors for SOC 2 Type II, PCI DSS 4.0, and FedRAMP accept CIS Docker scores…
Accessibility in React is not a separate layer applied after the component is built. It is a property of the component’s markup, and React’s rendering model gives you direct control over that markup. The WAI-ARIA specification defines roles, states, and properties that communicate the purpose and current condition of a UI element to assistive technology…
Rust’s asm! macro is the language’s escape hatch into the raw instruction set of the machine. It exists because some operations cannot be expressed in portable Rust, and some optimizations require control that even LLVM’s best efforts cannot provide. This chapter is about using that escape hatch responsibly: writing inline assembly that is correct, that…
Table partitioning is the practice of splitting one large logical table into smaller physical pieces called partitions, while keeping it accessible as a single table to the application. The motivation is not raw query speed—a well-indexed table can be fast without partitioning. The motivation is manageability at scale: a table with billions of rows becomes…
Every TypeScript project was once a JavaScript project. Some were started fresh with TypeScript from the first commit. Most were not. The typical migration story is a JavaScript codebase that has grown large enough that the absence of types has become a liability — bugs that only surface at runtime, refactoring that is risky because…
A Vue monorepo at scale is not a single tool decision. It is a layered architecture: a package manager that handles dependency resolution and workspace linking, and a build system that handles task orchestration, caching, and affected-project detection. The two layers are independent, and the most common production stack combines pnpm workspaces for the first…
