# Shower CLI

Command line interface for [Shower](https://shwr.me/) HTML slides engine.

## Quick start

```sh
npx @shower/cli new my-slides
```

## Installation

Install Shower CLI globally using npm:

```sh
npm install --global @shower/cli
```

The minimum supported Node version is v22.0.0.

After the slides are created, `@shower/cli` is added as a dev dependency by default. Inside the project, you can run commands via npm scripts:

```sh
npm run serve
npm run bundle
npm run archive
npm run pages
npm run pdf
```

### `shower bundle`

Gather the necessary files in a separate folder. The `slides` folder is self-contained and ready to deploy to a static host.

The Shower engine (`@shower/core`) and themes listed in `dependencies` are bundled automatically. Slides files are configured via the `"files"` field in `package.json`. By default, a new project includes:

```json
"files": [
	"pictures/**",
	"index.html"
]
```

Add any custom directories or files your slides need:

```diff
"files": [
	"pictures/**",
+    "demos/**",
	"index.html"
]
```
