Smile.customerReady().then((customer) => {
  if (customer) {
    // A customer was identified,
    // render a logged in state
  } else {
    // A customer was not identified,
    // render a logged out state
  }
}).catch(err => {
  // An error occurred while
  // identifying the customer
});
This method is deprecated. Specify includeSdk: true when initializing Smile UI, and then listen for the smile-js-initialized event from the JavaScript SDK instead.
This method is used to detect when customer identification has completed and is useful for wrapping any code (or other Smile methods) that require a logged-in customer. It can also be used to decide when to render a logged-in vs. logged-out state.

​
Returns

This method returns a Promise that resolves once customer identification has occurred (even if there is no logged-in customer) and does not wait for other dependencies. If customer identification has already occurred, the Promise will resolve immediately. The Promise will resolve with:
  • On success, a customer object when there is a currently logged-in customer, or null if no customer is currently logged-in.
  • On failure, an error object.
