This is the solution to the final task of CS50 Web course. It is a calendar app.

There was no requirement to write a calendar app nor anything similar for the course, so this project is new. It includes quite a lot of complex functionality, such as registering, logging in and out, viewing current or some other month, adding and deleting events, viewing all events and events for an arbitrary day.

The prerequisites for running it are Python 3.12, Pip 24.0, Node 22.0, NPM 10.5, and SQLite 3.43.

Clone the repository locally

In the calendarapp directory create migrations folder with an empty init.py file in it. Do the same in cs50web_capstone directory

In the project directory, create a .env file with the SECRET_KEY variable set to a random string

In the project directory, create a virtual Python environment: python -m venv venv

Activate it: source venv/bin/activate

Install Python packages with pip install -r requirements.txt

Install Node packages with npm install. Depending on your system, you might need to use python3 and pip3 instead

Create the database with python manage.py makemigrations and python manage.py migrate

Use npm run dev to run the Node.js dev server and python manage.py runserver to run the Django server

Upon loading the application, the user is presented with a login screen.

If this is his first time, he has to register providing his first and last names, email, and password.

Then he is redirected to the main screen, where he can see the calendar of the current month. He can move to other months by pressing blue navigation buttons.

He can view all of his events by pressing My Events button in the navigation bar. By pressing Delete button, he can delete an event.

He can insert an event by pressing Add Event button in the navigation bar.

If there is an event on a given day, this day is colored blue in the calendar view. By pressing on a day in calendar view, the user is redirected to that day's events view.

The project is created using the Django framework. Frontend is written in HTML and JavaScript. For styling, TailwindCSS is used. To make Django and Tailwind work, we use django-tailwind Python package and tailwindcss NPM package. The project consists of the default cs50web_final app, the calendarapp app where most of the code resides, and the theme app used for TailwindCSS purposes.

In the calendarapp/urls.py file, the URL endpoints are given. The view functions are given in the calendarapp/views.py file. There are three models described in calendarapp/models.py: CustomUserModel helper, User model, and Event model. The templates use Django templating language. The base template is layout.html. There are templatees for registering and logging in. There are templates for listing all events (event_list.html) and events for a given day (day_list.html). The calendar view comes from month_view.html template. Adding a new event resides with event.html template. Adding an event and displaying the calendar requires advanced front end functionality, which is given in event.js and month_view.js, respectively. In addition, there is a calendar favicon.
