Command Line Interface

The command line interface allows you to do most of the things you'd do with the JavaScript API.

First, install rollup as a global module:

npm install -g rollup

(Alternatively, if you're using the rollup command in the context of an npm run script, you can install it as a devDependency for each project, using npm i -D rollup.)

Run rollup -h or rollup --help to view usage instructions.
