Chat back end built with CDK, AWS AppSync, DynamoDB, and Amazon Cognito

CDK AppSync Chat

This CDK project deploys an AppSync API, Amazon DynamoDB tables, and an Amazon Cognito User Pool configured to create the infrastructure for a chat application. It is paired with a React front-end for a full-stack serverless project.

Deploying the back end

1. Clone the repo

git clone https://github.com/full-stack-serverless/cdk-appsync-chat.git

2. Change into the cdk-appsync-chat directory

3. Install dependencies in main folder:

npm install

# or

yarn

3. Deploy to AWS

cdk deploy

Once the project has been deployed, you'll be given the resources needed to configure the client-side React application.
