Jarvis is a suite of utilities for Webpack projects designed for bundle analysis, tree-shaking audits, build error debugging, and network performance simulation. It provides a browser-based dashboard to visualize asset distributions and monitor the total size of bundles and chunks. The project includes a network performance simulator that estimates how assets load across various connection types and speeds. It also features a tree-shaking analysis tool that measures the ratio of shakeable to non-shakeable module imports to identify opportunities for bundle size reduction. Additional capabili
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
Analyze bundle stats(bundle size, assets, modules, packages) and compare the results between different builds. Support for webpack, rspack, vite, rolldown and rollup.
