Order Notification & IoT Automation

This project provides a Node.js-based service for processing orders and sending notifications based on order value.

Features

• Processes orders and verifies required parameters (order and manager).
• Sends an email notification for high-value orders using SendGrid.
• Provides an email sending functionality using SendGrid API.
• Logs order processing and email notification details to the console.
• Provides a cURL command for invoking the service via OpenWhisk.
• Supports IBM Watson IoT Platform for event-based automation.

Installation

1. Clone this repository:

   git clone <REPO_URL>
   

2. Navigate to the project directory:

   cd <PROJECT_FOLDER>
   

3. Install dependencies:

   npm install
   

Usage

Call the main function with parameters:

const params = { from: "FROM_EMAIL", to: "TO_EMAIL", subject: "Test Subject", content: "Email content here" };
main(params)
  .then(response => console.log(response))
  .catch(error => console.error(error));

Environment Variables

Replace <SENDGRID_API_KEY>, <FROM_EMAIL>, and <TO_EMAIL> in the code with actual values.

OpenWhisk Integration

Export required environment variables and invoke the service using cURL:

export TYPE='Content-Type: application/json'
export AUTH='Authorization: Basic '`bx wsk property get --auth | awk '{printf("%s", $3)}' | base64 `
export NAMESPACE=<OW_NAMESPACE>
export API_ENDPOINT=<API_ENDPOINT>
curl -k -s -X POST -d '{"from": "FROM_EMAIL_ID", "to": "TO_EMAIL_ID","subject":"OpenWhisk Alert","content":"Hello from Serverless"}' -H "$TYPE" -H "$AUTH" https://$API_ENDPOINT/api/v1/namespaces/$NAMESPACE/actions/sendMail?blocking=true

IBM Watson IoT Platform Integration

Button to Bulb Communication

1. The button sends an event to Watson IoT Platform.
2. The subscribed application processes the event and triggers an action.
3. The action sends a command to turn the bulb on/off.
