In this series of liveProjects, you will take on the role of a developer for travel company SimpleTravel. It offers an all-inclusive trip booking service to customers. With the growth of SimpleTravel, more customers ask for flexible queries, but this is almost impossible to achieve with its REST APIs. After a couple of internal meetings it was decided to implement GraphQL APIs to replace the existing APIs.


Each project in this series covers a different stage of the replacement process until you have a fully functioning GraphQL API with authentication in place. We will start with the creation of a data source using Amazon DynamoDB, then implement the GraphQL API using AWS AppSync. We will then protect this API using Amazon Cognito.

These projects are designed for learning purposes and are not complete, production-ready applications or solutions.

here's what's included

Project 1 Create a Data Source with Amazon DynamoDB

In this liveProject, you’ll use the Amazon DynamoDB NoSQL database to replace SimpleTravel’s relational database. The company decided to use DynamoDB as its flexible schema is well suited to the changing nature of the data being stored. Furthermore, it’s fully managed by AWS so the company doesn’t need to deal with servers and low-level configurations. Once you’ve created the data store, you will implement a Lambda function to query data from it.

Project 2 Make a GraphQL API with AWS AppSync

In this liveProject, you’ll replace SimpleTravel’s existing REST API. The company has grown, and new consumers want to be able to customize data returned by this API. Due to the inflexible nature of the REST paradigm, the new API will be implemented using GraphQL.

Project 3 Push Notifications in AppSync

In this liveProject, you’ll use a GraphQL API implemented using AWS AppSync to add a new hotel to SimpleTravel’s records. Then, you’ll implement a GraphQL subscription to automatically notify consumers who are interested in these events. This approach will modernize the API for the travel company, supporting the scaling of its business.

Project 4 Restrict API Access with Amazon Cognito

In this liveProject, you’ll use Amazon Cognito to restrict access to a GraphQL API. Previously, SimpleTravel’s APIs were publicly accessible. But you’ve seen a surge of new customers, and now your boss wants to ensure that access is limited to authorized users. Your challenges include creating an Amazon Cognito user pool and implementing group-based authorization in AWS AppSync.
