Java To-Do List Service for LAN

A modern Java + Spring Boot + JavaScript To-Do List application featuring priority sorting and a RESTful API.

Screenshot from use on a computer:

Features

• Priority Sorting: Tasks are marked as High, Medium, or Low and are automatically sorted by priority.
• REST API: Backend built with Java 25 and Spring Boot.
• Modern UI: Clean interface using Bootstrap and JavaScript Fetch API.
• Persistent: Uses H2 file-based database which stores files safely to remain intact after updates.

Server Deployment

1. Clone the repo on your local machine

2. Package the project into an executable .jar file: mvn clean package (will appear in /target/)

3. Using SSH, WinSCP, FileZilla or any other service, get into your server

4. Create a directory for the app (e.g. todolist-app)

5. Transfer the .jar file into that directory

6. Create a service file so the service restarts in case of a server reboot or crash: sudo nano /etc/systemd/system/todo.service
   

7. Copy and paste this into the file: (change the User and Working Directory as needed)
