nativescript-hook plugin cannot be used in some cases

[rosen-vladimirov]

In some cases nativescript-hook cannot be used. This plugin is used by developers to easily create and maintain hooks for their plugins. As it has to execute some work on postinstall of the plugin, it has to be defined as dependency, not devDependency. However defining it as dependency is including it in the real application, that's installed on the device. But in case you define it as devDependency of the plugin, it will not be installed when calling npm install --save <my plugin> and the postinstall will fail.

Idea:

• Always use nativescript-hook as devDependency of the plugin. On postintall of the nativescript-hook or prepublish of the plugin, create postinstall.js and preuninstall.js which should not depend on nativescript-hook, but should do the same as it would do.
  Workflow in such case:
  1. Create plugin
  2. Add info in the package.json for required hooks
  3. Add nativescript-hook as dependency - this should add prepublish step to your package.json
  4. Executing npm pack will call prepublish step. This step will call nativescript-hook, which should read plugin's package.json and create postinstall.js and preuninstall.js with correct content. The content should execute the following code: https://github.com/NativeScript/nativescript-hook/blob/master/index.js#L74
