EXAMPLES

•

use settings in config file

rollup -c

•

in config file, process.env.INCLUDE_DEPS === ’true’

and process.env.BUILD === ’production’

rollup -c --environment INCLUDE_DEPS,BUILD:production

•

create CommonJS bundle.js from src/main.js

rollup --format=cjs --file=bundle.js -- src/main.js

•

create self-executing IIFE using window.jQuery

and window._ as external globals

rollup -f iife --globals jquery:jQuery,lodash:_ \
-i src/app.js -o build/app.js -m build/app.js.map

NOTES

•

When piping to stdout, only inline sourcemaps are permitted
