Analyze file sizes of rollup bundled imports

rollup-analyzer

Rollup Analyzer gives you a quick look at what's taking up space in your bundle.

Comes in three scrumptious flavors:

rollup-analyzer-plugin

Adding as a plugin to your rollup config or build script will print a well formatted analysis to the console upon bundling.

rollup-analyzer-config

If using Rollup's CLI to bundle with no additonal config, pass -c node:rollup-analyzer-config to print a well formatted analysis to your console.

rollup-analyzer

Full analysis module, giving you access to the complete analysis object or well formatted analysis text for CI and build usage.

Install

$ npm install --save-dev rollup-analyzer-config

Usage

rollup -c node:rollup-analyzer-config -f cjs -o index.js module.js

Results

Something like this will be logged to stderr on bundle completion
