Subject Overview

A comparative, practice-oriented study of backend development using Node.js and Django. The subject covers runtime and framework foundations, APIs, data persistence, security, testing, distributed systems, deployment, observability, governance, architectural decision-making, AI integration, and emerging industry practices.

Learning Goal

Students will be able to design, implement, secure, test, deploy, evaluate, and maintain production-ready backend systems using Node.js and Django while making justified architectural, operational, ethical, and technology decisions.

Syllabus

1. Backend Systems and Web Foundations

Learning Objective: Explain client–server architecture, HTTP/HTTPS, request–response lifecycles, DNS, ports, headers, cookies, sessions, serialization, statelessness, web servers, application servers, and backend responsibilities.

Category: foundation

2. Node.js and Django Ecosystems

Learning Objective: Compare JavaScript runtimes, the Node.js event loop, asynchronous I/O, npm, Express-style frameworks, Python execution, Django’s batteries-included model, project structures, package management, virtual environments, and framework selection criteria.

Category: foundation

3. Application Structure, Routing, and Middleware

Learning Objective: Build modular applications using routes, views/controllers, middleware, templates, configuration, dependency management, validation, error handling, logging, and environment-specific settings in both ecosystems.

Category: core

4. Data Modeling and Persistence

Learning Objective: Design relational schemas; apply normalization, keys, constraints, indexing, transactions, migrations, connection pooling, and ORM patterns using Django ORM and Node.js data-access libraries; recognize appropriate uses of NoSQL databases.

Category: core

5. RESTful API Design and Documentation

Learning Objective: Develop versioned REST APIs with resources, status codes, filtering, pagination, content negotiation, idempotency, validation, standardized errors, OpenAPI documentation, and backward-compatibility practices.

Category: core

6. Authentication, Authorization, and Identity

Learning Objective: Implement sessions, cookies, password hashing, token-based authentication, JWT, OAuth 2.0/OpenID Connect concepts, role- and attribute-based access control, permissions, account recovery, and secure identity lifecycle management.

Category: core

7. Secure Backend Engineering and Ethics

Learning Objective: Mitigate injection, XSS, CSRF, broken access control, insecure deserialization, dependency risks, secrets exposure, and denial-of-service threats using secure coding, OWASP guidance, threat modeling, privacy principles, responsible data use, and security governance.

Category: core

8. Asynchronous Processing and Real-Time Systems

Learning Objective: Apply promises, async/await, Node.js concurrency behavior, Django asynchronous capabilities, background jobs, task queues, schedulers, message brokers, WebSockets, event-driven patterns, retries, and failure handling.

Category: application

9. Testing, Quality Assurance, and Maintainability

Learning Objective: Create unit, integration, API, contract, security, and end-to-end tests; use mocking, fixtures, test databases, coverage, static analysis, linting, type checking, code review, refactoring, and continuous quality controls.

Category: application

10. Performance, Caching, and Scalability

Learning Objective: Profile applications and databases; diagnose bottlenecks; use caching, compression, pagination, query optimization, rate limiting, load balancing, horizontal scaling, CDN services, and capacity-planning metrics to meet performance objectives.

Category: application

11. Architecture and Distributed Backend Design

Learning Objective: Evaluate layered architecture, MVC/MTV, service and repository patterns, domain-driven concepts, modular monoliths, microservices, API gateways, service communication, eventual consistency, resilience, and architectural trade-offs.

Category: advanced

12. Containers, CI/CD, and Cloud Deployment

Learning Objective: Package applications with containers; configure databases, reverse proxies, process managers, and cloud services; build CI/CD pipelines; manage migrations, secrets, releases, rollback, infrastructure environments, and deployment strategies.

Category: application

13. Observability, Reliability, and Operational Governance

Learning Objective: Use structured logs, metrics, traces, health checks, dashboards, alerts, SLIs/SLOs, incident response, audit trails, backup and disaster recovery, cost analytics, dependency governance, licensing, and compliance controls.

Category: strategic

14. Contemporary Backend Development and Future Directions

Learning Objective: Assess serverless and edge computing, GraphQL, gRPC, platform engineering, zero-trust systems, supply-chain security, sustainable computing, AI-assisted development, and secure integration of AI services including model APIs, vector stores, privacy, evaluation, and responsible AI governance.
