# Minifiers

Remove whitespace, comments, and unnecessary characters from CSS and JavaScript.

## Commands

```bash
echo "body { color: red; margin: 0; }" | devv pipe exec "minify-css"
echo "function hello() { return 'world'; }" | devv pipe exec "minify-js"
```

## Examples

```bash
# Minify a CSS file
cat styles.css | devv pipe exec "minify-css"

# Minify JavaScript
cat script.js | devv pipe exec "minify-js"

# Minify and encode
cat styles.css | devv pipe exec "minify-css | base64-encode"
```

## Pipeline Usage

| Pipeline ID | Description |
|-------------|-------------|
| `minify-css` | Remove whitespace from CSS |
| `minify-js` | Remove whitespace from JavaScript |

```bash
devv pipe exec "minify-css" "body { color: red; }"
devv pipe exec "minify-js | hash-generator sha256" "function x() { return 1; }"
```

### Behavior

Both transform their input — the minified result passes to the next step.
