## Installation

```sh
# npm
npm install eslint-plugin-no-re-export --save-dev

yarn add eslint-plugin-no-re-export --dev

# bun
bun install eslint-plugin-no-re-export --save-dev
```

## Usage

Add `no-re-export` to the plugins section of your `.eslintrc` configuration file. You can omit the `eslint-plugin-` prefix:

```json
{
  "plugins": ["no-re-export"]
}
```

Then configure the rules you want to use under the rules section.

```json
{
  "rules": {
    "no-re-export/no-re-export": "error"
  }
}
```

## Rules

| Rule ID                                    | Description                                    |

  > Barrel exports increase bundle size and memory footprint, and are the only reason treeshaking is needed (to only-partially clean up sloppy importing), and in my experience, are best avoided, especially in any codebase of significant scale/size.
