How do I build an AWS DynamoDB table item?

To build and manage an AWS DynamoDB table item, you need to first set up a DynamoDB table and then define the table items you want to store. Below is an example where we’ll create a DynamoDB table for storing user data and then add an item to that table. We’ll define the resources needed and explain each part along the way.

Explanation

1. Provider Configuration: Begin by configuring the AWS provider to allow management of your AWS resources.
2. DynamoDB Table: Create a DynamoDB table with a specified primary key.
3. DynamoDB Table Item: Add an item to the DynamoDB table with the corresponding attributes required.

Program

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

export = async () => {
    const users = new aws.dynamodb.Table("users", {
        name: "users-table",
        billingMode: "PAY_PER_REQUEST",
        hashKey: "user_id",
        attributes: [{
            name: "user_id",
            type: "S",
        }],
        tags: {
            Environment: "dev",
            Name: "users-table",
        },
    });
    const userItem = new aws.dynamodb.TableItem("user_item", {
        tableName: users.name,
        hashKey: "user_id",
        item: `{
  "user_id": {"S": "123"},
  "name": {"S": "John Doe"},
  "email": {"S": "john.doe@example.com"}
}
`,
    });
    return {
        tableName: users.name,
        userItem: userItem.item,
    };
}

Summary

We’ve created a program to set up a DynamoDB table and add an item to it. The example includes defining the AWS provider, creating a DynamoDB table with a primary key, adding an item to that table, and outputting the table name and item. This demonstrates how to manage and work with DynamoDB tables and items effectively.
