Getting Started

Node and Yarn is required.

1. yarn install to install dependencies
2. (Optional) Install Prettier VSCode extension, if you want to play around while keeping code consistency

Viewing Examples

Choose a design pattern by changing the enum in the example variable in src/index.ts.

enum DesignPattern {
    FACTORY = 'factory',
    MEMENTO = 'memento',
    STATE = 'state',
    ITERATOR = 'iterator',
    COMPOSITE = 'composite',
    BRIDGE = 'bridge',
    MEDIATOR = 'mediator',
    PROXY = 'proxy',
    CHAIN_OF_RESPONSIBILITY = 'chain',
    FLYWEIGHT = 'flyweight',
}

const example: DesignPattern = DesignPattern.FLYWEIGHT // Edit here

1. yarn build to transpile Typescript to Javascript
2. yarn start to run the script
3. (Optional) yarn dev to run a nodemon development server
