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 });
