logs Event type

The logs event type allows you to handle events generated from AWS Cloud Watch operations. The following is a sample event from the AWS Lambda documentation:

{
    "awslogs": {

        "data": "eW91ciBsb2cgZ29lcyBoZXJl"
    }
}

To map the event using Vandium, we would use the logs() handler:

const vandium = require( 'vandium' );

exports.handler = vandium.logs( (event, context) => {

        // do something with the data
    });

Your handler can return a Promise or value. If you require the use of a callback function for asynchronous operations that cannot be done using Promises, then you can provide a callback parameter in your code.

const vandium = require( 'vandium' );

exports.handler = vandium.logs( (event, context, callback) => {

        // do something with the data

        // Must invoke callback() since Vandium thinks you would like to control asynchronous operations yourself
        callback( null, 'ok' );
    });
