Install it

npm i -g source-map-explorer

Yarn:

yarn global add source-map-explorer

Make sure you've built your project; with Codesplain, that's

npm run build

Yarn:

yarn build

Go to the static js files; for Codesplain, that's

cd build/static/js

Run source-map-explorer on the bundled JS file and its map, like so:

source-map-explorer main.js main.js.map

Marvel at all of the unneccessary code in your bundle.
Make an alias so you don't have to type out source-map-explorer (I use sme)
