とりあえずブチ込むやつ.js

//AWS Lambda function
//required environment variables:["tableName"]

'use strict';

console.log('Loading function');

const doc = require('dynamodb-doc');

const dynamo = new doc.DynamoDB();


exports.handler = (event, context, callback) => {
    console.log('Received event:', JSON.stringify(event, null, 2));

    const done = (err, res) => callback(null, {
        statusCode: err ? '400' : '200',
        body: err ? err.message : JSON.stringify(res),
        headers: {
            'Content-Type': 'application/json',
        },
    });

    var DynamoRequest = {
        "TableName": process.env.tableName,
        "Item" : {
            "timestamp": new Date().getTime(),
            "payload": JSON.stringify(event.body)
        }

    dynamo.putItem(DynamoRequest, done);
};
