## Description

Webpack bundle size analyzer is a command-line tool and diagnostic utility that inspects compiled Webpack build output to report the exact file size and percentage contribution of each individual module and package. It operates via JSON-driven static analysis against build output files, parsing and traversing abstract syntax trees and dependency graphs to calculate precise byte weights without altering original execution code.

The tool sorts and aggregates parsed module metrics by file size and percentage share to highlight the largest bundle contributors. It provides terminal stream output and file-system report export capabilities, allowing developers to review sorted size breakdowns directly in the command-line interface or write serialized composition summaries to disk during the standard compilation lifecycle.
