Usage

The store API is mostly events based. As a user of this plugin, you will have to register listeners to changes happening to the products you register.

The core of the listening mechanism is the when() method. It allows you to be notified of changes to one or a set of products using a query mechanism:

store.when("product").updated(refreshScreen);
store.when("full version").owned(unlockApp);
store.when("subscription").approved(serverCheck);
store.when("downloadable content").downloaded(showContent);
etc.

The updated event is fired whenever one of the fields of a product is changed (its owned status for instance).

This event provides a generic way to track the status of the purchases, to unlock features and to refresh the views accordingly.

API references

This section describes some of the main functions used in the demo. For complete API references, please refer to the repository.

store.verbosity

The verbosity property defines how much the code in the store.js file writes to the console. Available values:

• store.QUIET or 0 to disable all logging (default)

• store.ERROR or 1 to show only the error messages

• store.WARNING or 2 to show also the warnings

• store.INFO or 3 to show also the information messages

• store.DEBUG or 4 to show also the internal debugging messages.

// Enable maximum logging level
store.verbosity = store.DEBUG;

store.register()

Register a product to the store.

store.register(product);

});

store.refresh()

Load the product data from the servers and restore whatever has already been purchased by the user.

store.refresh();

Example

// ...
// register products and events handlers here
// ...
//
// then and only then, call refresh.
store.refresh();

store.get(id/alias)

Retrieve a product by its id or alias.
