// {statusCode: 200, body: '{"data": []}'}

callback(null, okResponse);

};

Shorthand methods for common HTTP statuses


- response.ok = response.createResponse({statusCode: 200, ...})
- response.created = response.createResponse({statusCode: 201, ...})
- response.deleted = response.createResponse({statusCode: 204, ...})
- response.badRequest = response.createResponse({statusCode: 400, ...})
- response.unauthorized = response.createResponse({statusCode: 401, ...})
- response.forbidden = response.createResponse({statusCode: 403, ...})
- response.notFound = response.createResponse({statusCode: 404, ...})
- response.unprocessableEntity= response.createResponse({statusCode: 422, ...})
- response.serverError = response.createResponse({statusCode: 500, ...})

Default parameters

Default values for every response. It gets overriden if new values are provided during the function call.

`javascript
const options = {
body: { message: 'Hello World' },
headers: {'Content-Type': 'application/json' }
};

const response = require('lambda-proxy-integration-response')(options);

response.ok();
// { statusCode: 200, headers: { 'Content-Type': 'application/json' }, body: '{"message": "Hello World}'}

response.ok({ body: { message: 'Hey', headers: {} } });
// { statusCode: 200, headers: { }, body: '{"message": "Hey}'}
`
