Dynamo DB Stream event data parser for the middy framework, like json body parser but for dynamodb stream events
Simply uses AWS sdk's DynamoDB Document Client Converter to convert the data received in the New/Old Image of all records to plain json.
## Why?
Taking inspiration from Json Body Parser, we decided to export this simple middleware we built
## Install
To install this middleware you can use NPM:
```bash
npm install --save @distinction-dev/dynamo-unmarshall
```
## Sample usage
```javascript
const middy = require('@middy/core');
const dynamoUnmarshall = require('@middy/error-logger');
const handler = middy((event, context) => {
// your handler logic
})
handler
.use(dynamoUnmarshall())
```
## Options
- `aws` property: The instance of the `aws-sdk`, If none is provided then it will simply import it.
- `imageTypes` property: An array providing which image types to convert can only contain `"NewImage", "OldImage"`.
- `converterOptions` property: The options that you wanna pass to the DynamoDB converter.
