esbuild Architecture: How is it So Fast?
· 阅读时间 1 分钟
TLDR:
esbuild reaches compiler-level speed through a parallel scan/link/print pipeline, minimal whole-AST passes, and incremental build contexts. This article shows practical CLI and API recipes for bundling, minifying, code splitting, and metafile analysis, explains how Vite and Vitest leverage esbuild, and compares trade-offs with Webpack and SWC—then connects it all to Feature-Sliced Design for scalable, maintainable frontend architecture.
