# html-inject-script
Transform stream for injecting script tags into html.
### example:
```js
var injectScripts = require('html-inject-script')
process.stdin
.pipe( injectScripts(['./app.js', './extra.js']) )
.pipe( process.stdout )
```
input:
```html
hello
```
output:
```html
hello
```
### api
#### `require('html-inject-script')(scripts[, opts])`
Injects an array of scripts. Accepts an object of options:
- `selector` (`string`, default: `'head'`): A [hyperstream](https://github.com/substack/hyperstream) selector into which the tags are injected
- `prepend` (`boolean`, default: `true`): If true, prepends. If false, appends.
### cli
```bash
cat index.html | htmlinjectscript "app.js" > output.html
```
```
usage: cat index.html | htmlinjectscript "app.js" > output.html
Options:
--body -b, inject into the body element (default: head)
--selector -s, override head or body with a specific selector
--append -a, append to selector instead (default: prepend)
--help, -h display this message
```
### Gotcha:
requires the tag (head, body, or otherwise) to be present in the src.
