CommandableLambdaService

Abstract service that receives commands via the AWS Lambda protocol to operations automatically generated for commands defined in ICommandable components. Each command is exposed as an invoke method that receives a command’s name and parameters.

Extends: LambdaService

Description

The CommandableLambdaService allows you to create abstract services that receive commands via the AWS Lambda protocol to operations automatically generated for commands defined in ICommandable components. Each command is exposed as an invoke method that receives a command’s name and parameters.

Important points

This service is intended to work inside a LambdaFunction container that exploses registered actions externally.

Configuration parameters

dependencies:
- controller: override for Controller dependency

References

*:logger:*:*:1.0: (optional) ILogger components to pass log messages.
*:counters:*:*:1.0: (optional) ICounters components to pass collected measurements.

Constructors

Creates a new instance of the service.

public constructor(name: string)

name: string - service name.

Instance methods

register

Registers all actions in AWS Lambda function.

public register(): void

Examples

class MyCommandableLambdaService extends CommandableLambdaService {
   public constructor() {
      base();
      this._dependencyResolver.put(
          "controller",
          new Descriptor("mygroup","controller","*","*","1.0")
      );
   }
}

let service = new MyCommandableLambdaService();
service.setReferences(References.fromTuples(
   new Descriptor("mygroup","controller","default","default","1.0"), controller
));

await service.open("123");
console.log("The AWS Lambda service is running");
