Serverless iOS App with AWS Lambda and Amazon Bedrock

This repository contains the code to build a native iOS app with Swift, leveraging Amazon Bedrock's AI capabilities to power chat and image generation features. The app uses a serverless backend built on AWS Lambda with TypeScript, enabling seamless processing without the need for provisioning servers or containers.

Features

• AI-Powered Chat: Generate responses in a chat-like interface using Amazon Bedrock.
• Image Generation: Create images from prompts powered by Amazon Bedrock's models.
• Serverless Backend: Leverage AWS Lambda and API Gateway to handle backend processing with minimal infrastructure management.

Architecture

The app follows a serverless architecture to minimize operational overhead. Key AWS services used:

• Amazon Bedrock: For AI-driven chat and image capabilities.
• AWS Lambda: Serverless compute for processing requests.
• Amazon API Gateway: API management for routing requests to Lambda functions.

Getting Started

Prerequisites

• AWS Account: To access Amazon Bedrock and AWS Lambda services.
• Node.js: For managing Lambda function code and dependencies.
• AWS CLI (optional): To manage AWS resources directly from the command line.
• Deployment Tool: Choose your preferred tool for deploying Lambda functions in this project I have chosen Serverless Framework

Setup Instructions

1. Clone the Repository:

   git clone https://github.com/rashwanlazkani/amazon-bedrock-back
   cd amazon-bedrock-back

2. Configure AWS: Ensure your AWS credentials are set up locally, or configure them using aws configure

3. Initialization: Run the following commands to install dependencies and build the project:

yarn
yarn build

4. Deployment: To deploy the application, run:

sls deploy

Make sure you have completed the steps above and have set the correct AWS region in your configuration.

5. Endpoints: After a successful deployment you will be provided with the endpoints to your Lambdas in the console

6. Sample prompts:

   • Text:

    Method: POST
    Body:
    {
        "prompt": "Explain the benefits of mindfulness meditation."
    }

   Image:

    Method: POST
    Body:
    {
        "prompt": "Generate an image of a sunny beach with palm trees."
    }
