TripleCheck: DynamoDB database repository
Database utility for using DynamoDB with TripleCheck broker. It implements the repository base at triplecheck-core.
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:
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<any> {
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
];
}
