Code samples

These declarations will establish a connection to the database located on localhost:

import AWS from "aws-sdk";

AWS.config.update({
  region: "us-west-2",
  endpoint: "http://localhost:8000"
});

var dynamodb = new AWS.DynamoDB();

These declarations will create a useUpdateLink from code to the table “Music”.

/* This example adds a new item to the Music table. */

var params = {
  Item: {
    "AlbumTitle": {
      S: "Somewhat Famous"
    }, 
    "Artist": {
      S: "No One You Know"
    }, 
    "SongTitle": {
      S: "Call Me Today"
    }
  }, 
  ReturnConsumedCapacity: "TOTAL", 
  TableName: "Music"
};
dynamodb.putItem(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});
