AWS DynamoDB with Next.js API Routes

AWS DynamoDB with Next.js API Routes
Type: Code
Framework: Next.js
CSS: Vanilla CSS
  • Project Description: A Next.js application demonstrating CRUD operations (Create, Read, Update, Delete) using AWS DynamoDB for document management.
  • Demo: Experience the application live at https://alt-text-generator.vercel.app/.

Usage Options:

  1. Existing DynamoDB Table:
    • Retrieve AWS access key, secret key, region, and table name.
    • Provide these values upon deployment to set environment variables automatically.
  2. New DynamoDB Table Setup:
    • Bootstrap the project with pnpm create next-app using the provided example URL.
    • Create a new IAM role with AmazonDynamoDBFullAccess permissions.
    • Save the access key, secret key, and create a new DynamoDB table with a primary key id of type String.
    • Configure .env.local with the AWS credentials and table details.
    • Launch the Next.js application using pnpm dev and access it at http://localhost:3000.
    • Deploy to Vercel following their documentation.

Credentials and Environment Variables:

  • AWS credentials and region can be directly set as environment variables for Vercel deployments (e.g., AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION).
  • The AWS SDK automatically detects these environment variables, simplifying the code by eliminating the need to manually pass credentials to AWS client instances.

Testing CRUD Operations:

  • PUT: Add a new item with a content field.
  • GET: Retrieve an item by its id.
  • POST: Update an existing item’s content by specifying its id.
  • DELETE: Remove an item by its id.
