CLI tool to specify and control per page JS bundle limit for Next.js applications

# next-page-budget

Simple CLI, that lets you define your per page maximum size for JS in Next.js applications.

## Configuration

`next-page-budget` looks for configuration in the following order:
* `nextPageBudget` key in `package.json`
* `.next-page-budget.json`
* `.next-page-budget`
* `.next-page-budget.js`
* `.next-page-budget.cjs`

```json
{
  "compression": "gz",
  "pages": {
    "/auth": { "limit": "300 kB", "compression": "brotli" },
    "/profile": "500 kB"
  }
}
```

Compression can be:
* `gzip` or `gz` for gzip
* `brotli` or `br` for brotli
* `none` - without compression

When `compression` is not specified, `gzip` is used. Page's `compression` overwrites common setting.

## Run

In your Next.js project add new script to `package.json`:
```json
{
  "scripts": {
    "check-size": "next-page-budget"
  }
}
```

And then build your Next.js application:
```bash
node run-script build
node run-script check-size
```
