Class default

constructor

• new default(current?: string): default

ETL_API - The URL of the API to use ETL_LAYER - The Integer Layer ID to get config information and post results to ETL_TOKEN - The access token specific to the Layer

  Parameters

  • Optionalcurrent: string

  Returns default

  A Layer Config Object

outgoing

• outgoing(event: SQSEvent): Promise<boolean>

• Parameters

  • event: SQSEvent

  Returns Promise<boolean>

schema

• schema(type?: SchemaType, flow?: DataFlowType): Promise<TSchema>

• The extended class should override this function if it needs additional user-defined config values or wants to provide a Schema

  Input: By default it simply adds a DEBUG boolean which will conditionally print CoT GeoJSON in the logs if true.

  Output: Does not provide a defined schema. Providing a schema allow the User to perform mapping and styling operations

  Parameters

  • type: SchemaType = SchemaType.Input
  • flow: DataFlowType = DataFlowType.Incoming

  Returns Promise<TSchema>

  A JSON Schema Object

setEphemeral

• setEphemeral(ephem: Record<string, string>): Promise<void>

• Set ephemeral key/values Overwrites existing values, if any

  Parameters

  • ephem: Record<string, string>

  Returns Promise<void>

  A Layer Config Object
