1. Clone our project repository

git clone https://github.com/vocaAppServerless/frontend.git

2. Install Dependencies and run Before starting the React project, you need to install the required dependencies. Run the following command:

npm install

3. Start the Application

npm start

1. Clone our project repository

git clone https://github.com/vocaAppServerless/backend.git

2. Install AWS SAM CLI

• Windows
  • Download the installer from the AWS SAM CLI Download Page.
  • Run the installer and follow the on-screen instructions.
  • Add the installation path (usually C:\Program Files\Amazon\AWSSAMCLI\bin) to your PATH environment variable if not automatically configured.
• macOS
  • Install using Homebrew:

  brew install aws/tap/aws-sam-cli

3. Build and Test API Gateway with Lambda To build the API Gateway and Lambda environment using SAM, run:

sam build --no-cached
sam local start-api --env-vars ./env.json --no-cached

env.json for SAM CLI

{
  "<lambda-name-1>": {
    "ENV_FIRST": "...",
    "ENV_SECOND": "///"
  },
  "<lambda-name-2>": {
    "ENV_FIRST": "...",
    "ENV_SECOND": "///"
  }
}

The added warning ensures users understand that environment variables are crucial for the proper functioning of Lambda functions and must be specified correctly in the env.json file.

HCP Terraform is integrated with a VCS (Version Control System) to provision and manage AWS resources through code. Using Infrastructure as Code (IaC) principles, all AWS resources are defined and versioned, ensuring consistency, repeatability, and ease of management.
