## TripleCheck: DynamoDB database repository

Database utility for using DynamoDB with TripleCheck broker. It implements the repository base at [triplecheck-core](https://github.com/mikaelvesavuori/triplecheck-core).

## Instructions

You will need to have a pre-existing DynamoDB table. Use `id` (String type) as the primary partition key.

## Basic implementation

In your `triplecheck-broker` implementation, do a regular import for `triplecheck-repository-dynamodb` and pass the repository to the broker. In a Lambda context, an implementation could look like:

```TypeScript

import { TripleCheckBroker } from 'triplecheck-broker';

import { DynamoRepository } from 'triplecheck-repository-dynamodb';

export async function handler(event: any) {

  const repository = DynamoRepository();

  const [request, payload] = await getRequestData(event);

  const { responseData, status, headers } = await TripleCheckBroker(request, payload, repository);

  const response = {

    statusCode: status,

    body: JSON.stringify(responseData),

    headers

  };

  return response;

}

/**

 * @description Utility function to get the data we need to run the TripleCheck broker.

 * Expects the full AWS Lambda event object.

 */

async function getRequestData(event: any): Promise {

  const { body, httpMethod, path, queryStringParameters } = event;

  const payload = body && typeof body === 'string' ? JSON.parse(body) : body;

  const search = (() => {

    let _search = '';

    if (queryStringParameters && JSON.stringify(queryStringParameters) !== '{}') {

      _search += Object.keys(queryStringParameters)[0];

      _search += Object.values(queryStringParameters)[0];

    }

    return _search;

  })();

  return [

    {

      method: httpMethod,

      pathname: path || '/',

      search

    },

    payload

  ];

}

```
