This article explains CSS's invisible flow mechanism, compares block and inline elements to water flow, and details how width, height, and box‑sizing affect layout, providing practical insights for creating fluid and robust front‑end designs.
This article explores the concept of micro‑frontends, introduces the Qiankun framework, demonstrates its rendering workflow with practical code examples, and details an APAAS‑based architecture for integrating and managing micro‑applications, covering client‑side SDK, server proxies, routing, sandboxing, CSS isolation, and third‑party SDK challenges.
This article introduces Rust to front‑end developers, covering its origins, safety‑focused design, key language features such as ownership and borrowing, core data types, structs, enums, and practical code examples to help readers grasp why Rust is worth learning.
This article explores several techniques—including MutationObserver, IntersectionObserver, ResizeObserver, onload listeners, and an iframe hack—to reliably detect when a rich‑text container with images exceeds a maximum height so a "show more" button can be displayed.
This article explains how Tencent created the open‑source TDesign system, its multi‑team organization, rule‑based governance, tooling, GitHub automation, documentation strategy, and contributor incentives, showing how a large‑scale design system can stay consistent while evolving across many technology stacks.
This article explains what race conditions are in front‑end web development, demonstrates the issue with a React demo fetching articles, and walks through step‑by‑step solutions using custom hooks, useEffect cleanup, and AbortController to safely cancel outdated requests and avoid stale data rendering.
This article explores how to implement smooth scrolling using CSS and JavaScript, compares native scroll APIs, demonstrates practical React examples, explains how to differentiate user‑initiated and script‑driven scrolling, and provides compatibility tips and workarounds for common pitfalls.
This article explains what a JavaScript Promise is, why it solves callback‑hell in asynchronous code, details its three states, and walks through a complete hand‑written implementation—including the constructor, then method, resolvePromise logic, and how to verify compliance with the Promises/A+ test suite.
This article explains how script and stylesheet elements influence the timing of the DOMContentLoaded event, detailing the effects of async, defer, and external CSS on HTML parsing, supported by HTML5 specifications and performance analysis, to help developers optimize page load speed.
This article explains how TypeScript’s never, unknown, and any types work, compares their roles as top and bottom types, shows practical code examples for safe type narrowing, and demonstrates advanced scenarios such as unreachable‑code detection, type operations, exhaustive checks, and proper use of never in real‑world projects.
