Enpal Coding Challenge

This project is a Node.js application with a PostgreSQL database, containerized using Docker and Docker Compose.

Prerequisites

Make sure you have the following installed on your system:

• Docker
• Docker Compose
• Node.js and npm (for local development)

Running the Application with Docker Compose

To build and start the entire application using Docker Compose, run the following command:

docker-compose up --build

Running the PostgreSQL Database Container Separately

If you prefer to run the database container separately, you can follow these steps:

1. Navigate to the database directory:

   cd database

2. Build the PostgreSQL Docker image:

   docker build -t enpal-coding-challenge-db .

3. Run the PostgreSQL container:

   docker run --name enpal-coding-challenge-db -p 5432:5432 -d enpal-coding-challenge-db

This will run the PostgreSQL container in the background and expose it on port 5432.

---

Running the Tests (Node.js Application)

To run the tests for the Node.js application after starting the PostgreSQL database, follow these steps:

1. Navigate to the test-app directory:

   cd test-app

2. Install the dependencies:

   npm install

3. Start the Node.js server:

   npm start

The server will now be running on http://localhost:3000/ and making POST Request on http://localhost:3000/calendar/query and will communicate with the PostgreSQL database.

Accepted Query Format

The following type of query is accepted by the application:

{
  "date": "2024-05-04",
  "products": ["Heatpumps","SolarPanels"],
  "language": "English",
  "rating": "Silver"
}

4. Run the tests in new terminal:

   npm test

The tests will now run, and you'll see the output of your tests in the terminal.

Note

.env file is included in the project for simplification.

When both services are when started in docker-compose communicate using private network
