Serverless JavaScript Projects 4.2: Setting Up the UI with DynamoDB Database

This video tutorial covers setting up a UI with a DynamoDB database, focusing on integrating authentication and AJAX calls. It explains card operations, API integration, and security measures for serverless endpoints. The tutorial also previews upcoming content on creating, reading, updating, and deleting Lambda functions for cards and boards, emphasizing the separation of user data management through Auth0.

What is the first step in setting up the UI with DynamoDB?

• Accessing the AWS console

• Creating a new card

• Checking authentication

• Making an Ajax call

What must be checked before creating a new card?

• API endpoint availability

• UI responsiveness

• User authentication

• Database connection

Why is a timeout used when updating card tags?

• To prevent data loss

• To ensure the tag change is recognized

• To reduce server load

• To improve UI performance

What is the purpose of making an Ajax call when a card is dropped?

• To authenticate the user

• To create a new card

• To delete the card

• To update the card's tag

What is the strategy for API authentication in this setup?

• Using OAuth tokens

• Open APIs with no restrictions

• Using API keys

• Tying authentication to the front end

What will the upcoming Lambda functions focus on?

• UI enhancements

• User authentication

• CRUD operations for cards and boards

• Database schema design

Why is there no need for a user database in this setup?

• The application does not require user data

• User data is stored in cookies

• All data is stored in the front end

• Users are managed by a third-party service
