DurableContext interface

Signature:

export interface DurableContext<TLogger extends DurableLogger = DurableLogger>

Properties

Property	Modifiers	Type	Description
lambdaContext		Context	The underlying AWS Lambda context
logger		DurableContextLogger<TLogger>	Logger instance for this context, optionally enriched with durable execution metadata if the logger supports it. By default the default logger will emit logs following this structure: { "timestamp": "2025-11-21T18:39:24.743Z", "executionArn": "arn:aws:lambda:...", "level": "INFO", "operationId": "abc123", "message": { "userId": "123", "action": "login" } "requestId": "72171fff-70c9-4066-b819-11d3eb549de0", }
promise		{ all<TOutput>(name: string | undefined, promises: DurablePromise<TOutput>[]): DurablePromise<TOutput[]>; all<TOutput>(promises: DurablePromise<TOutput>[]): DurablePromise<TOutput[]>; allSettled<TOutput>(name: string | undefined, promises: DurablePromise<TOutput>[]): DurablePromise<PromiseSettledResult<TOutput>[]>; allSettled<TOutput>(promises: DurablePromise<TOutput>[]): DurablePromise<PromiseSettledResult<TOutput>[]>; any<TOutput>(name: string | undefined, promises: DurablePromise<TOutput>[]): DurablePromise<TOutput>; any<TOutput>(promises: DurablePromise<TOutput>[]): DurablePromise<TOutput>; race<TOutput>(name: string | undefined, promises: DurablePromise<TOutput>[]): DurablePromise<TOutput>; race<TOutput>(promises: DurablePromise<TOutput>[]): DurablePromise<TOutput>; }
