Configuration

A topic can be configured in settings.ts via the key notification.(topic) The configuration parameters of a topic are the following:

Attribute	Type	Description
ttl	number	The number of milliseconds the notification will remain in the topic before being automatically deleted. Set the value to 0 for no expiration Example: Set the TTL to 5000 for the sucess topic, so that the notification is only displayed during 5 seconds. Defaults to: 5000 (0 for error topic)
max	number	The maximum number of notification stored in a topic. If a new notification is added when the topic is full, the oldest notification is deleted. Set the value to 0 for no limit Defaults to: 5 (0 for error topic)
persist	boolean	A flag to indicate if the notification should survive after a route change. Defaults to: true

tip

The values in settings.ts becomes the default values for a topic. These values can be overridden when sending a notification

Configuration example

// content of settings.ts
export default {
  notification: {
    error: { // 'error' is the name of the topic
      ttl: 0,
      max: 3,
      persist: true
    },
    success: {
      ttl: 2000,
      max: 3,
      persist: false
    },
    'login-error': {
      ttl: 0,
      max: 1,
