source-map-explorer. Very neat tool for creating a tree map visualization of the size of the components of a bundled JavaScript file created by webpack (or if you’re using create-react-app by “npm run build”). I ran this using “npx source-map-explorer build/static/js/main.d63f3f34.js” (since I don’t like using “npm install -g”).
