Listening to events

Our client was built with an event-first approach, and every module has its own set of events that you can listen to.

​

Types of events

There are two types of events that you can listen to:

• State change events: These events are triggered when a module’s variable changes value. All variables are observable, and their corresponding events will always have the same name as the variable, followed by Changed.
• Custom events: These events represent some specific action that has occurred in the module.

​

Listening to events

To listen to a module’s event, you need to call the on method on the module instance, passing the event name and a callback function as arguments.

You can just as easily remove the listener by calling the off method on the module instance, passing the event name and the same callback function as arguments.

const handleAuthSuccess = (user) => {
  console.log('User logged in', user)
}

dynamicClient.auth.on('authSuccess', handleAuthSuccess)

// When you no longer need to listen to the event

dynamicClient.auth.off('authSuccess', handleAuthSuccess)

​

List of events

You can find all the events that a module emits in the module’s documentation — for instance, take a look at the auth module’s documentation here.

However, for your convenience, below is a list of all the events that the client emits. Please refer to the module’s documentation for more information on each event.

​
