Description

The IDiscovery interface is used to create discovery services which are used to store and resolve connection parameters used to connect to external services.

Instance methods

register

Registers connection parameters into the discovery service.

register(context: IContext, key: string, connection: ConnectionParams): Promise<ConnectionParams>

  • context: IContext - (optional) a context to trace execution through call chain.
  • key: string - a key to uniquely identify the connection parameters.
  • connection: ConnectionParams - a connection to be registered.
  • returns: Promise<ConnectionParams> - the registered connection parameters.

resolveAll

Resolves all connection parameters by their key.

resolveAll(context: IContext, key: string): Promise<ConnectionParams[]>

  • context: IContext - (optional) a context to trace execution through call chain.
  • key: string - a key to uniquely identify the connections.
  • returns: Promise<ConnectionParams[]> - a list with resolved connections.

resolveOne

Resolves a single connection parameters by its key.

resolveOne(context: IContext, key: string): Promise<ConnectionParams>

  • context: IContext - (optional) a context to trace execution through call chain.
  • key: string - a key to uniquely identify the connection.
  • returns: Promise<ConnectionParams> - a resolved connection.
