Calendar Merger Project

Overview

The Calendar Merger project is a web application that allows users to merge multiple calendars into a single calendar. It provides a simple and intuitive interface for users to:

• Add calendars
• Specify prefixes for each calendar
• Override event summaries if desired

The application also generates a unique URL for the merged calendar and updates it every hour using a cron job.

Features

• Merge multiple calendars into a single calendar
• Specify prefixes for each calendar
• Optionally override event summaries
• Generate a unique URL for the merged calendar
• Automatically update the merged calendar every hour

Requirements

• Node.js (version 14 or higher)
• npm (included with Node.js)

Installation

1. Clone the repository:

   git clone git@forge.ftt.gmbh:ryanmwangi/CalMerger.git
   

2. Install the dependencies:

   npm install
   

3. Start the server:

   npm start
   

Building and Running with Docker

1. Build the Docker Image

Run the following command to build the Docker image:

docker build -t calmerger-app .

2. Run the Docker Container

To start the container, use:

docker run -d --name calmerger -p 3000:3000 calmerger-app

This maps the container's port 3000 to the host system's port 3000. The application will be accessible at http://localhost:3000.

3. Using Docker Compose (Optional)

If you prefer to use Docker Compose, ensure you have a docker-compose.yml file in your project directory. Then, run:

docker-compose up -d

This will automatically build and start the container based on the configuration in the docker-compose.yml file.

4. Stopping the Docker Container

To stop the running container, use:

docker stop calmerger

To remove the container:

docker rm calmerger

Running Tests

This project uses Jest for testing to ensure the Calendar Merger works as expected.

Run the test suite:

npm test

Jest will automatically locate and execute all test files, providing pass/fail status and error details in your terminal.

For additional insights, you can run tests in coverage mode:

npm test -- --coverage

This generates a coverage report, showing how much of the codebase is tested.
