Deno Todo App

This is a simple Todo app built with Deno, Hono, and MongoDB. The app allows you to create, update, toggle, and delete todos. It uses Docker Compose to run the application and MongoDB in separate containers.

Prerequisites

Make sure you have the following installed on your system:

• Docker
• Docker Compose

Getting Started

Follow these steps to run the app:

1. Clone the Repository

git clone https://github.com/youdaman/deno_todo_app.git
cd deno_todo_app

2. Start the Application

Run the following command to start the app using Docker Compose:

docker-compose up --build

This will:

• Build the deno-app container
• Start the deno-app container and the mongo container

3. Access the App

Once the containers are running, you can access the app in your browser at:

http://localhost:3000

4. Stopping the Application

To stop the app, press Ctrl+C in the terminal where Docker Compose is running, or run:

docker-compose down

This will stop and remove the containers.

Project Structure

• main.ts: The main application file that defines the API routes and connects to MongoDB
• index.html: The frontend of the Todo app
• docker-compose.yml: The Docker Compose configuration file
• readme.md: This file

Environment Variables

The app uses the following environment variables:

• DENO_ENV: Set to development by default in docker-compose.yml

You can modify these variables in the docker-compose.yml file if needed.

Troubleshooting

Common Issues

1. MongoDB Connection Error:

   • Ensure the mongo container is running
   • Check the logs of the mongo container:

     docker-compose logs mongo

2. Port Already in Use:

   • Make sure port 3000 (for the app) and 27017 (for MongoDB) are not being used by other processes

3. Rebuilding the Containers:

   • If you make changes to the code, rebuild the containers:

     docker-compose up --build
