Backend Development

See backend/README.

Frontend Development

In this sample, you can locally modify and launch the frontend using AWS resources (API Gateway, Cognito, etc.) that have been deployed with cdk deploy.

  1. Refer to Deploy using CDK for deploying on the AWS environment.
  2. Copy the frontend/.env.template and save it as frontend/.env.local.
  3. Fill in the contents of .env.local based on the output results of cdk deploy (such as BedrockChatStack.AuthUserPoolClientIdXXXXX).
  4. Execute the following command:
cd frontend && npm ci && npm run dev

Using Streaming

Currently, the environment variable VITE_APP_USE_STREAMING is specified on the frontend side. It's recommended to set it to false when running the backend locally and true when operating on AWS.
When streaming is enabled, text is generated in real-time due to the streaming of content generation results.

Using docker compose

If you prefer to handle all of resources as Docker, docker-compose.yml allows you to run and develop frontend / backend APIs / DynamoDB Local in your local environment.
