> Like gulp.watch but for npm scripts.

## Install

```bash

$ npm install -D nswatch

```

## Usage

Assuming you have an npm script `build` to compile something, then drop a `watch.js` in your project:

```js

import { watch } from "nswatch";

watch("src/*.js", ["build"]);

```

When you run `node watch`, the `npm run build` will be invoked right away, and will also be invoked when file changes are detected.



### Parallel and Sequence

`Array` will be treated as parallel, `String` will be treated as sequence:

```js

// run in parallel

watch("src/a.js", ["task-a", "task-b"]);

// run in sequence

// use ! as seperator

watch("src/b.js", "task-a!task-b");

```

## CLI

```bash

$ npm install -g nswatch

```

You can also use `nswatch` as a command-line program:

### Configure `watch` in `package.json`

```json

{

  "watch": {

    "./src/*.js": ["build"],

    "./src/*.css": "compile!minify"

  }

}

```

Then run:

```bash

$ nswatch

```

Or you can pass the config via CLI arguments, this way configurations in `package.json` will be ignored.

```bash

# in parallel

$ nswatch "src/*.js" --script foo --script bar

# in sequence

$ nswatch "src/*.js" --script "foo!bar"

```
