• provider-info.json - Provider information
• config-mongo.json - Contains database url
• config-kafka.json - Connection parameters for kafka
• config-server.json –
  • host, port - server api parameters
  • max_concurrency - maximum number of simultaneously processed messages
  • first_attempt_timeout - message timeout on first send ( if 0, no timeout )
  • next_attempts_timeout - message timeout on subsequent send
  • max_attempts - maximum number of retry attempts to send
  • retry_time_base - the base of the number to calculate the delay time between retransmissions. Time between dispatches is calculated as n^x, where n is retry_time_base and x is a number of unsuccessful attempts.

Run node init.js to initialize the database.

Run node index.js to start the notification provider.

Consumer

The consumer is an intermediate layer, he receives messages from the provider, decrypts them and forwards them to another address in accordance with the specified rules. In fact, it would be more correct to call this module a router For the convenience of users, the consumer has an admin panel. It simplifies consumer configuration and allows you to view the last received messages in decrypted form.

Edit configs in configs folder:

• config-mongo.json - Contains database url
