Instance methods

configure

• config: ConfigParams - configuration parameters to be set.

resolve

Resolves connection and credential parameters and generates a single GcpConnectionParams value.

public resolve(correlationId: string): Promise<GcpConnectionParams>

• correlationId: string - (optional) transaction id used to trace execution through the call chain.
• returns: Promise<GcpConnectionParams> - receives an GcpConnectionParams value or error.

setReferences

Sets references to dependent components.

public setReferences(references: IReferences): void

• references: IReferences - references to locate the component’s dependencies.

Examples

let config = ConfigParams.fromTuples(
    'connection.uri', 'http://east-my_test_project.cloudfunctions.net/myfunction',
    'connection.protocol', 'http',
    'connection.region', 'east',
    'connection.function_name', 'myfunction',
    'credential.project_id', 'my_test_project',
    'credential.auth_token', '1234',
);
   
let connectionResolver = new GcpConnectionResolver();
connectionResolver.configure(config);
connectionResolver.setReferences(references);
    
const connectionParams = await connectionResolver.resolve("123");
