Properties

queueUrl: string

The SQS queue URL.

s3Bucket: string

The S3 bucket name.

alwaysAcknowledge?: boolean

By default, the consumer will treat an empty object or array from either of the handlers as a acknowledgement of no messages and will not delete those messages as a result. Set this to true to always acknowledge all messages no matter the returned value.

false

alwaysUseS3?: boolean

Whether to always use S3 regardless of message size

false

attributeNames?: QueueAttributeName[]

List of queue attributes to retrieve, see AWS docs.

[]

authenticationErrorTimeout?: number

The duration (in milliseconds) to wait before retrying after an authentication error.

10000

batchSize?: number

The number of messages to request from SQS when polling (default 1).

This cannot be higher than the AWS limit of 10.

1

extendedAWSErrors?: boolean

Set this to true if you want to receive additional information about the error that occurred from AWS, such as the response and metadata.

handleMessageTimeout?: number

Time in ms to wait for handleMessage to process a message before timing out.

Emits timeout_error on timeout. By default, if handleMessage times out, the unprocessed message returns to the end of the queue.

heartbeatInterval?: number

The interval (in seconds) between requests to extend the message visibility timeout.

On each heartbeat the visibility is extended by adding visibilityTimeout to the number of seconds since the start of the handler function.

This value must less than visibilityTimeout.

messageAttributeNames?: string[]

List of message attributes to retrieve (i.e. ['name', 'address']).

[]

messageSystemAttributeNames?: MessageSystemAttributeName[]

A list of attributes that need to be returned along with each message.

[]

pollingCompleteWaitTimeMs?: number

If you want the stop action to wait for the final poll to complete and in-flight messages to be processed before emitting 'stopped' set this to the max amount of time to wait.

0

pollingWaitTimeMs?: number

The duration (in milliseconds) to wait before repolling the queue.

0

receiveTransform?: ReceiveTransformFunction

Custom function to process message bodies when receiving If provided, overrides the default behavior

region?: string

The AWS region.

process.env.AWS_REGION || eu-west-1

s3?: { credentials?: any; region?: string }

The S3 client options.

s3Prefix?: string

The S3 prefix.

s3TtlSeconds?: number

The S3 TTL in seconds.

sendTransform?: SendTransformFunction

Custom function to determine if a message should be stored in S3 If provided, overrides the default behavior based on message size

shouldDeleteMessages?: boolean

Default to true, if you don't want the package to delete messages from sqs set this to false.

true

sizeThreshold?: number

The size threshold in bytes. Messages larger than this will be stored in S3.

262144

sqsClientOptions?: { credentials?: any; region?: string }

The SQS client options.

suppressFifoWarning?: boolean

Set this to true if you want to suppress the warning about FIFO queues.

false

terminateVisibilityTimeout?: number | boolean | (messages: Message[]) => number

If true, sets the message visibility timeout to 0 after a processing_error. You can also specify a different timeout using a number. If you would like to use exponential backoff, you can pass a function that returns a number and it will use that as the value for the timeout.

false

useQueueUrlAsEndpoint?: boolean

Set this value to false to ignore the queueUrl and use the client's resolved endpoint, which may be a custom endpoint.

true

useReceiptHandleMarkers?: boolean

Whether to use receipt handle markers to track S3 content

true

visibilityTimeout?: number

The duration (in seconds) that the received messages are hidden from subsequent retrieve requests after being retrieved by a ReceiveMessage request.

waitTimeSeconds?: number

The duration (in seconds) for which the call will wait for a message to arrive in the queue before returning.

Methods

  • An async function (or function that returns a Promise) to be called whenever a message is received.

    In the case that you need to acknowledge the message, return an object containing the MessageId that you'd like to acknowledge.

    Parameters

    • message: Message

    Returns Promise<void | Message>

  • An async function (or function that returns a Promise) to be called whenever a batch of messages is received. Similar to handleMessage but will receive the list of messages, not each message individually.

    If both are set, handleMessageBatch overrides handleMessage.

    In the case that you need to ack only some of the messages, return an array with the successful messages only.

    Parameters

    • messages: Message[]

    Returns Promise<void | Message[]>

  • An async function (or function that returns a Promise) to be called right after the SQS Client sends a receive message command.

    This function is usefull if SQS Client module exports have been modified, for example to add middlewares.

    Returns Promise<void>

  • An async function (or function that returns a Promise) to be called right before the SQS Client sends a receive message command.

    This function is usefull if SQS Client module exports have been modified, for example to add middlewares.

    Returns Promise<void>
