        }, function(err, data) {
            if (err) {
                context.fail('ERROR: Dynamo failed: ' + err);
            } else {
                console.log('Dynamo Success: ' + JSON.stringify(data, null, '  '));
                context.succeed('SUCCESS');
            }
        });
}

Thanks for the example. Here is an updated version. I changed the table name to devices. The DynamoDB setup has changed a little. I just went with a simple key on device.

console.log('Loading event');
var doc = require('dynamodb-doc');
var dynamodb = new doc.DynamoDB();

exports.handler = function(event, context) {
    console.log("Request received:\n", JSON.stringify(event));
    console.log("Context received:\n", JSON.stringify(context));

    var tableName = "devices";
    var datetime = new Date().getTime().toString();
    var item = {
        "device": event.device, 
        "timedate": datetime,
        "latitude": event.lat,
        "longitude": event.lon
    };
    console.log("Item:\n", item);

    dynamodb.putItem({
            "TableName": tableName,
            "Item": item
        }, function(err, data) {
            if (err) {
                context.fail('ERROR: Dynamo failed: ' + err);
            } else {
                console.log('Dynamo Success: ' + JSON.stringify(data, null, '  '));
                context.succeed('SUCCESS');
            }
        });
}

Thank You so much for this-it has enormous value when combined with additional tutorials

Hi, thanks for the code. I want to know how to store and retrieve photo url in dynamodb from s3?

Wow - your blog and this code was crazy helpful. Thank you!

Thanks for this, great example. I never thought of using API gateway. I'm just curious what you are doing if any records fail for whatever reason to insert into DynamoDB?

Hello,

Im trying to pass some params like this,

const params = {
        uuid: generateUUID().uuid,
         status: "new",
         owner: r.format.filename.split("/")[3],
         file_size: r.format.size,
         duration: r.format.duration,
         master_file: {
            duration: r.format.duration,
            format: {
                bitrate: r.format.bitrate
            }
         }
}

but when it comes to table,

format: {
bitrate: r.format.bitrate
}

it comes as empty.

Any idea why?

helps would be appreciated.
