next-unused v0.0.6

next-unused

next-unused is an easy way to find unused files in your Next.js project.

Installation

Make sure you install as a devDependency, otherwise you will add 60mb+ to your build.

$ yarn add next-unused -D

Usage

In package.json, add a script to find unused files:

"scripts": {
  "find:unused": "next-unused"
}

Run the script to list any unused files: yarn find:unused.

Configuration

Add a property to your package.json to configure next-unused:

{
  "next-unused": {
    "alias": {},
    "include": [],
    "exclude": [],
    "entrypoints": []
  }
}

Example

Your Next.js setup looks like this:

package.json
├─ pages/
│  ├─ index.js
└─ components/
   ├─ button.js
   └─ image.js

And your pages/index.js contains:

import Button from '../components/button'

export default () => {
  return (
    <Button>Click me</Button>
  )
}

Configure next-unused to include the components directory in package.json:

{
  "next-unused": {
    "include": ["components"]
  }
}

Running next-unused will output:

Found 1 unused file:
components/image.js
