TypeScript’s incremental compilation, introduced in version 3.4, speeds up build times by reusing previous build information stored in a tsBuildInfoFile, and this article explains the entry points, how old and current programs are created, change detection rules, and configuration of the buildInfo file.
This article explains how ByteDance measures website performance, introduces key front‑end performance metrics such as FP, FCP, LCP, TTI, TBT, FID, and MPFID, describes the APIs and code needed to collect them, and discusses how to evaluate and improve overall site performance using these indicators.
This article examines the design goals, key implementation details, strengths and weaknesses of four widely used memory allocators—dlmalloc, jemalloc, Scudo, and PartitionAlloc—highlighting how they address fragmentation, performance, and security in virtual‑machine runtimes and offering guidance for building efficient, safe allocators.
This article explains the bundle‑less approach—including splitting bundles, no‑bundle development, and modular dependency distribution—presents performance tests that suggest an optimal chunk count of 10‑25, evaluates Vite’s advantages and drawbacks, and outlines a self‑built import‑map‑based solution with code examples.
The article explains how a frontend monitoring SDK can support diverse environments such as web, mini‑programs, and Electron by decoupling logic into interchangeable roles, providing a rich plugin lifecycle, enabling business‑driven extensions, on‑demand loading, and rigorous quality controls while minimizing impact on the host application.
This article examines why Git struggles with monolithic repositories exceeding 100 GB, outlines storage, performance, stability, and reliability challenges, and presents preventive, mid‑process, and post‑process strategies—including LFS, shallow and partial clones, commit‑graph, bitmap, multi‑pack index, and bundle techniques—to efficiently manage and maintain large Git monorepos.
This article describes how to add Hot Module Replacement to esbuild by disabling scope hosting, converting modules to CommonJS, building a custom ModuleLoader and resolver, handling module URLs, and comparing two bundling approaches while also covering React Refresh integration.
This article walks through a real Git‑induced failure, explains how to reproduce and diagnose the nested process loop, analyzes the underlying commit‑graph and alternates interactions, and then details step‑by‑step how to seek help and contribute a fix to the Git open‑source community.
The June 25 ByteDance‑ByteDance Dev Better technical salon, co‑hosted with Huatai Securities, presented a series of front‑end engineering talks covering serverless web development, modern.js engineering, DevOps adoption, and practical Q&A, offering valuable insights and best‑practice recommendations for web developers.
WebAssembly, a portable binary format, is evolving into a mature platform; this article surveys its motivations, language support (C/C++, Rust, Go, Java, AssemblyScript, etc.), toolchains, and major runtimes such as Wasmtime, Wasmer, WasmEdge, and WAMR, highlighting performance, security, and integration aspects.
