## rollup-config-analyzer

See what's bloating your bundle, how treeshaking has treated you, and other
great stuff. Perfect for console printing an analysis of your bundle or
integrating in your CI workflows.

### Comes in two scrumptious flavors:

#### [rollup-plugin-analyzer](https://github.com/doesdev/rollup-plugin-analyzer)
Adding as a plugin to your rollup config or build script will allow you to
print a well formatted analysis to the console upon bundling or get a full
analysis object for CI purposes.

#### [rollup-config-analyzer](https://github.com/doesdev/rollup-config-analyzer)
If using Rollup's CLI to bundle with no additional config, pass
`-c node:rollup-config-analyzer` to print a well formatted analysis to your console.

## Install

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

## Usage

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

## Results
Something like this will be logged to stderr on bundle completion
```sh
