Assignment

Assigment is accomplished with the latest Node LTS 18.16.1.

Write the function

Requirements: function (fn) that aggregate inputs (strings) and return it if there is no input for examples

Code examples:

console.log(fn("hello").fn("world").fn("!!!").fn())
//Will print: hello world !!!

console.log(fn("This").fn("is").fn("just").fn("a").fn("test").fn())
//Will print: This is just a test

Function:

class Fn {
constructor() {
 	this.state = [];
}

fn(string) {
	if (string === undefined) {
		return this.state.join(" ");
	} else {
		this.state.push(string);
		return this;
		}
	}
}

function fn(string) {
	const fnObj = new Fn();
	return fnObj.fn(string);
}

Build Full Stack application

Description of the assignment: Please implement a small cart system, the cart will present 1 product to purchase with 2 plans type: monthly subscription base and yearly subscription. Please create a UI that allows the user to add and remove from the cart. Once the user choose the product and the plan the cart should redirect to a purchase form when the user will insert his credit card information.

Note: prepare development environment (production and deployment is not required).

Chosen technologies:

Frontend:

• 3 routes are created with React
• MUI
• Error and loading components are added, not found pages
• Cookies are used for: items storage in the card for not logged in usersa

Backend:

• 10 routes are build with Nest.js and MongoDB
• Dependency injection for base service is implemented
• Documentation is provided with Swagger (http://localhost:5000/api)
• JWT authentication is ready for implemention
• 2 guards are added
• Decorator for extracting JWT token is created
• 4 models for MongoDB are added and described
• 2 Dockerfiles are added to backend and frontend
• MongoDB exists on Mongo Atlas
• API tests are added

Start project (development environment)

Copy environmental variables

cp ./server/.development-example.env ./server/.development.env
cp ./client/.example.env ./client/.env

Run DEV

docker-compose up -d

or

yarn dev

Run tests manually

yarn test

Next steps:

• Implement authentification on front end
• Add exisiting guards to routes on backend
