## Usage

```js
var isValid = require('{%= name %}');

// in your Base plugin
function plugin(app) {
  // plugin name is required as the second argument
  if (!isValid(app, 'my-plugin')) return;
  // do plugin stuff
}
```

Optionally pass an array of instance types as the third argument:

```js
function plugin(app) {
  if (!isValid(app, 'my-plugin', ['view', 'collection'])) return;
  // do plugin stuff
}
```

## History

**v0.3.0**

- upgrades [is-valid-instance][] to v0.3.0, which adds support for checking `app.type` for the instance type. We don't expect any regressions, but if you experience one, please [create an issue](../../issues/new).
