source-map-explorer is a source map bundle analyzer that visualizes the space usage of bundled JavaScript files. It functions as a bundle size auditor and visualizer, using source maps to identify which original modules and files occupy the most space within a production bundle. The tool generates an interactive treemap to represent bundle composition and calculates compressed gzip sizes to estimate actual network transfer costs. It further serves as a code coverage mapper by overlaying execution data onto source maps to identify unused code segments that can be deferred or split. The utilit
