DynamoDB JavaScript SDK v2 v3: manage items – 4

Renzo Mischianti
Spread the love

In the last article we had saw how many type of request we can do, but now we are going to see the basic operation that we can do over the single data.

DynamoDB JavaScript SDK v2 and v3 manage items

We also repeat the data addition methods seen in the last chapter.

Add an item

SDK v2

First we will see the asynchronous script, as in the previous parts.
To execute this script go in the folder dynamodb-examples\jsv2 and launch node item_add.js

var AWS = require("aws-sdk");

AWS.config.update({
    apiVersion: '2012-08-10',
    region: "eu-west-1",
    // endpoint: "http://localhost:8000",
    // // accessKeyId default can be used while using the downloadable version of DynamoDB.
    // // For security reasons, do not store AWS Credentials in your files. Use Amazon Cognito instead.
    // accessKeyId: "9oiaf7",
    // // secretAccessKey default can be used while using the downloadable version of DynamoDB.
    // // For security reasons, do not store AWS Credentials in your files. Use Amazon Cognito instead.
    // secretAccessKey: "yz5i9"
});

var ddb = new AWS.DynamoDB();

console.log("Start script!");

var params = {
    TableName: "TestTableMischianti",
    Item: {
        "ItemId": {S: "mischianti"},
        "ItemName": {S: "www.mischianti.org"},
        "ValueStr": {S: "Mischianti main url"},
        "ValueNum": {N: "1"},
    }
};


ddb.putItem(params, function (err, data) {
    if (err) {
        console.error("Unable add item", JSON.stringify(params, null, 2), ". Error JSON:", JSON.stringify(err, null, 2));
    } else {
        console.log("PutItem succeeded:", JSON.stringify(params, null, 2), data);
    }
});

console.log("End script!");

The result in console is

D:\Projects\AlexaProjects\dynamodb-management\dynamodb-examples\jsv2>node item_add.js
Start script!
End script!
PutItem succeeded: {
  "TableName": "TestTableMischianti",
  "Item": {
    "ItemId": {
      "S": "mischianti"
    },
    "ItemName": {
      "S": "www.mischianti.org"
    },
    "ValueStr": {
      "S": "Mischianti main url"
    },
    "ValueNum": {
      "N": "1"
    }
  }
} {}

Check the parameter syntax

var params = {
    TableName: "TestTableMischianti",
    Item: {
        "ItemId": {S: "mischianti"},
        "ItemName": {S: "www.mischianti.org"},
        "ValueStr": {S: "Mischianti main url"},
        "ValueNum": {N: "1"},
    }
};

we must specify the defined key (check the create table article), than you can add the values you need, the S or N value is the type of the data S --> String and N --> Number.

Now the asynchronous version (node item_add_async_await.js).

        }
    };

    try {
        const data = await ddb.putItem(params).promise();
        console.log("PutItem succeeded:", JSON.stringify(params, null, 2), data);
    }catch (err) {
        console.error("Unable add item", JSON.stringify(params, null, 2), ". Error JSON:", JSON.stringify(err, null, 2));
    }

    console.log("End script!");})();

As already described the difference was only the execution order.

SDK v3

In v3 version there are some change and Amazon advise to use async await (synchronous) with modularization of import. But we are going to restart from the last article syntax.

Now the asynchronous (discouraged mode) versione of the add script.

To execute this script go in the folder dynamodb-examples\jsv3 and launch node item_add.js

    ).catch(

    ).finally(
        () => console.log("END Of execution!")
    );

console.log("End script!");

The console output become more verbose and we have additional information.

D:\Projects\AlexaProjects\dynamodb-management\dynamodb-examples\jsv3>node item_add.js
Start script!
End script!
PutItem succeeded: {
  "TableName": "TestTableMischianti",

    },
    "ValueNum": {

    }
  }
} { '$metadata':
   { httpStatusCode: 200,

     attempts: 1,
     totalRetryDelay: 0 },
  Attributes: undefined,
  ConsumedCapacity: undefined,
  ItemCollectionMetrics: undefined }
END Of execution!

In detail we have l’http status code to identify the status of response (httpStatusCode: 200), and for the developer it is now explicit that we work with REST calls.

Now the synchronous script (node item_add_async_await.js)

Check the data

  1. You can find all the data in the DynamoDB section of the AWS console, go to this link (check the region).
https://eu-west-1.console.aws.amazon.com/dynamodb/home?region=eu-west-1#
  1. Click on Table/Tabelle;
  2. Select TestTableMischianti table;
  3. Click on element tab.
DynamoDB Table items from AWS console

Delete items

The logic is the same for all command, so now we are going more fast.

SDK v2

Here the synchronous script (node item_delete.js).

    Key: {
        "ItemId": {S: "mischianti"},
        "ItemName": {S: "www.mischianti.org"}
    }

ddb.deleteItem(params, function (err, data) {
    if (err) {

    } else {
        console.log("DeleteItem succeeded:", JSON.stringify(params, null, 2), data);
    }
});

console.log("End script!")

You can see that in the params we must specify all the declared key, you can’t omit one key.

var params = {
    TableName: "TestTableMischianti",
    Key: {
        "ItemId": {S: "mischianti"},
        "ItemName": {S: "www.mischianti.org"}
    }
};

and here the console output.

D:\Projects\AlexaProjects\dynamodb-management\dynamodb-examples\jsv2>node item_delete.js
Start script!
End script!
DeleteItem succeeded: {
  "TableName": "TestTableMischianti",
  "Key": {
    "ItemId": {
      "S": "mischianti"
    },
    "ItemName": {
      "S": "www.mischianti.org"
    }
  }
} {}

No result is exposed.

And now the asynchronous script (node item_delete_async_await.js).

Get Items

It’s time to retrieve the item we had inserted, you can get that information by filtering for all the declared key.

SDK v2

To execute this script go in the folder dynamodb-examples\jsv2 and launch node item_get.js

It’s quite simple, you only must specify the table and the key in the params

var params = {
    TableName: "TestTableMischianti",
    Key: {
        "ItemId": {S: "mischianti"},
        "ItemName": {S: "www.mischianti.org"},
    }
};

at the same way you can use a synchronous script item_get_async_await.js:
