`updates` is a CLI tool which checks for npm dependency updates of the current project and optionally updates `package.json`. It is highly configurable and is typically able to complete in less than a second.

# Usage

```bash
# check for updates
npx updates

# update package.json and install them
npx updates -u && npm i
```

## Bun and Deno

```bash
bunx updates
deno run -A npm:updates
```

## Options

See `--help` or below for the available options. Option that take multiple arguments can take them either via comma-separated value or by specifying the option multiple times. If an option has a optional `pkg` argument but none is given, the option will be applied to all packages instead.
