This project is a food ordering system. That implements all three types of design patterns

You can run the app in two modes. You can use the typescript ts-node runner or the compiled JS code. To do that follow these steps:

$ git clone https://github.com/async69/design-pattern-example.git
$ cd design-pattern-example/
$ yarn // To install the packages
$ yarn start:dev // To start code by ts-node
OR
$ yarn build // To compile TS code
$ yarn start // To run compiled JS code

You can see the builder implemented in the kitchen. All the recepies featuring and making all the complementary pizzas

All the sauss added to the code is created here. All the external additions and external features can be added easily just by updating the decorator.

The best part of the system. It's the notification system that notifies the customers when their food arrives
