is-valid-app

Wrapper around is-valid-instance and is-registered for validating base plugins. Returns true if app is a valid instance of base and a plugin is not registered yet.

Install

Install with npm:

$ npm install --save is-valid-app

Usage

var isValid = require('is-valid-app');

// 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:

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

Visit base for more details.
