# AWS Lambda Event Handler

This package provides a decorator for Python Lambda functions handling individual records in the `event` payload of the AWS Lambda function.

## Usage

This package provides two event decorators:

- **sns** - used to handle invokations that origin from a SNS Topic.
- **dynamodb** - used to handle invokations that origin from a DynamoDB Stream.

## Defining the Handler

The following demonstrates how to create a handler object that will be used as the entrypoint for various event sources that trigger a AWS Lambda invokation:

```python
from lambda_handler import LambdaHandler
handler = LambdaHandler() #pylint: disable=C0103
```

The handler object can then be used as a decorator for various Lambda Event Sources:

```python
from lambda_handler import SNSMessage

@handler.sns
def sns(message: SNSMessage, context) -> None:
    """
    Handle SNS Message
    """
    print(message)

@handler.dynamodb
def dynamodb(record: dict, context) -> None:
    """
    Handle DynamoDB record
    """
    print(record)
```

## Models

### SNSMessage

The `SNSMessage` model makes it easier to interact with the data in the records and does some of the heavy lifting of pulling payload and attributes from the event letting you focus on your business logic.

## Installation

```bash
pip install aws-lambda-event-handler
```

## Requirements

None
