This practical subject focuses on architecture, development, and deployment of web applications. It is language/framework-agnostic, but the examples will be in Java/Spring Boot, JavaScript/node.js for the backend, React.js for the frontend, and MySQL, MongoDB, Neo4j for the databases.

The subject includes coding in the front-end and in the back-end, administering basic elements of a web server, connecting with a database, designing and implementing API-driven front-end applications, designing and implementing REST and GraphQL APIs following market standards, protecting applications against the most usual security threats, and deploying web applications online. Basic web service concepts like cookies and sessions will be addressed. The students will not only learn to develop web applications, but they will also gather a deeper understanding of web architectures and web development environments.

Students will acquire the following knowledge:
- Web Development Architectures
- HTTP Protocol and Methods
- PWA – Progressive Web Applications
- Client-side vs Server-side rendering
- Security:
--- Authentication: JWT, sessions, cookies
--- Authorization
--- Hashing and encryption
--- SQL injections
--- XSS, CSRF
--- CORS

- The Front-End:
--- HTML5
--- CSS3, Flexbox, Grid
--- JavaScript and the DOM
--- Ajax
--- API Consumption
--- SPA – Single page application
--- React.js:
------ Logging
------ Routing
------ Pagination, filtering, sorting
------ Forms + input validation
------ Building reusable components

- The Back-End:
--- Web servers
--- APIs:
------ REST API
------ GraphQL
------ + others like SOAP, RPC, and event driven APIs
--- Databases

- Online Web Application Deployment
--- CI/CD pipeline
--- Testing:
------ Unit tests
------ Integration tests
------ End to end tests
--- Scaling:
------ databases, backend, frontend
------ Technologies: Containers, Kubernetes

The students will acquire the following skills:
- Front-end web development
- Back-end web development
- API development and consumption
- Web application deployment

The students will acquire the following competences:
- Design the architecture of a web application
- Work with a web development environment
- Create full-stack web applications
- Create applications that connect to external APIs
- Deploy web applications online
