In order to best conform with Rollup recommendations for plugin naming and also provide a more integrated solution this module is no longer active. The new version has many enhancements over this so please switch to it.
Please use rollup-plugin-analyzer
Analyze file sizes of rollup bundled imports
Rollup Analyzer gives you a quick look at what's taking up space in your bundle.
Adding as a plugin to your rollup config or build script will print a well formatted analysis to the console upon bundling.
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.
Full analysis module, giving you access to the complete analysis object or well formatted analysis text for CI and build usage.
$ npm install --save-dev rollup-analyzer-plugin
import analyze from 'rollup-analyzer-plugin'
const opts = {limit: 5, filter: [], root: __dirname}
export default {
entry: 'module.js',
dest: 'index.js',
format: 'cjs',
plugins: [analyze(opts)]
}
import { rollup } from 'rollup'
const opts = {limit: 5, filter: [], root: __dirname}
import analyze from 'rollup-analyzer-plugin'
rollup({
entry: 'main.js',
plugins: [analyze(opts)]
}).then(...)
logged to console on rollup completion
