How techiesrishti/webslim works
WebSlim analyzes a submitted website’s JavaScript and CSS usage, reports unused code and estimated savings, and offers library recommendations, code migration, and optimized-code downloads. The README also describes basic performance insights. The sampled backend shows Puppeteer Coverage analysis and carbon-impact calculation; the frontend excerpts show analysis, migration, visualizations, and report/download interactions. Some frontend-to-backend wiring and performance-metric details are unsampled, so those links are omitted.
