Prerequisites

  • Node.js and npm
  • AWS CLI
  • AWS SAM CLI
  • Docker (for local development)

Setup

  1. Install Dependencies:

    cd src
npm install

  2. Configure Environment Variables:

    Create an env.json file in the root directory with the following content:

    {
  "TWILIO_ACCOUNT_SID": "your_twilio_sandbox_account_sid",
  "TWILIO_AUTH_TOKEN": "your_twilio_sandbox_auth_token",
  "OPENAI_API_KEY": "your_openai_api_key"
}

Running Locally

  1. Run SAM CLI Locally:

    For Unix-based systems (Linux, macOS):

    sam local start-api --env-vars env.json

Debugging

  1. Configure VS Code for Debugging: [Broken at the moment]

    Create or update the launch.json file in the .vscode directory with the following content:

    {
  "version": "0.2.0",
  "configurations": [
    {
      "reason": "Its broken at the moment"
    }
  ]
}

  2. Add a Debugging Script in package.json [Broken at the moment]

    Ensure the debugging script in package.json is also updated to use the new port.

    {
  "scripts": {
    "debug": "sam local invoke ExpressApi --template template.yaml --env-vars env.json --debug-port 9229"
  }
}

  3. Start the Debugger [Broken at the moment]

    • Open VS Code.
    • Go to the Run and Debug view by clicking the play icon on the sidebar or pressing Ctrl+Shift+D.
    • Select "SAM CLI Debug: Node.js" from the dropdown menu.
    • Click the green play button or press F5 to start debugging.

  4. Verify No Conflicting Processes

    Make sure no other process is using the port 9229:

    For Unix-based systems (Linux, macOS):

    lsof -i :9229

    If you find a conflicting process, you can terminate it to free up the port.

Testing

Run tests using Mocha (ensure Mocha is installed as a dev dependency):

npm test

Deployment

Deploy the SAM Application:

sam deploy --guided

Follow the prompts to complete the deployment setup.
