Description of MVC

Here is simple diagram of components of MVC pattern in C4 notation. Each component is responsible for a different part of the processes. In MVC pattern you have 3 layers / components:

1. Controller. Processes HTTP requests, extracts parameters from requests. Used to implement the loose coupling between interface and logic layers
2. Model. Stores business logic and logic of working with entities, works directly with the database. Essentially the core of the application
3. View. UI. Renders content based on data from the model. Users see and work directly with the view

Run app

1. Install the necessary packages with npm install
2. Install express and handlebars with npm i express hbs
3. To run app just use npm start
