s3events v0.0.13

s3events

s3events is a command line tool to simulate and send AWS S3 events to new or existing event handlers. Supports SNS, SQS, Lambda.

Sample use cases:

• Resend s3 object created events to event handlers.
• Simulate object removal events without deleting objects.

Installation

npm install -g s3events

Send object creation events in prefix to all attached event handlers

Usage: s3events notify-all <event> <s3Path>
--event   Event type[required] [choices: "ObjectCreated:*", "ObjectRemoved:*", "ReducedRedundancyLostObject"]
--s3Path  Example: s3://prefix

# Example
s3events notify-all ObjectCreated:* s3://bucket-name/data/2017/07/01/18

# Use --dryrun flag to see actions without sending notification
s3events notify-all ObjectCreated:* s3://bucket-name/data/2017/07/01/18 --dryrun

Send object creation events in prefix to another SNS topic

Usage: s3events notify-sns <event> <topicArn> <s3Path>
--event     Event type
                    [required] [choices: "ObjectCreated:*", "ObjectRemoved:*", "ReducedRedundancyLostObject"]
--topicArn  SNS topic ARN
--s3Path    Example: s3://prefix

# Example
# Use --suffix flag to selectively send objects
s3events notify-sns ObjectCreated:* arn:aws:sns:us-east-1:123456789:SNSTopicName s3://bucket-name/data/2017/07/01/18 --suffix .gz

Sample S3 event

• Not all the fields of the official S3 event are sent, for example: awsRegion, userIdentity, requestParameters, etc are not sent.
• Only the following fields are sent.

      },
