esbuild-lazy-analyzer

A CLI tool (v1.4.0, active development) that analyzes lazy-loading in esbuild chunk splits using the metafile output. It generates static JSON statistics and interactive HTML dependency graphs showing chunk composition, eager vs lazy imports per entry point, length of dependency chains, and file-level bundle impact. Unlike general esbuild visualizers (e.g., esbuild-visualizer), this focuses on code-splitting optimization, showing which chunks are lazy-loaded and their sizes, enabling developers to identify opportunities for improved lazy-loading. It produces a self-contained HTML report with interactive import graphs and modals for per-file import inspection.
