Full Stack JavaScript Developer Course

Lesson 1 • HTML and CSS Essentials

Reviews semantic HTML structure and CSS layout models including Flexbox and Grid. These skills support every frontend component built in subsequent chapters.

Lesson 2 • Version Control with Git

Teaches branching, committing, merging, and remote workflows using Git. Version control underpins every collaborative and deployment task in later chapters.

Lesson 3 • Development Environment Configuration

Installs and configures Node.js, VS Code, Git, and terminal tools. A consistent local environment prevents tooling friction throughout the course.

Lesson 1 • Arrays, Objects, and Destructuring

Teaches array and object manipulation, spread/rest syntax, and destructuring patterns. These patterns appear in every React component and Node.js module in later chapters.

Lesson 2 • Asynchronous JavaScript

Covers the event loop, callbacks, Promises, and async/await syntax. Async fluency is essential for all API calls and database operations in the backend chapters.

Lesson 3 • Variables, Types, and Operators

Covers let, const, primitive types, type coercion, and operator precedence. Eliminates common bugs caused by misunderstood JavaScript type behaviour.

Lesson 4 • ES Modules and Modern Tooling

Introduces ES module syntax, bundlers, and transpilers. Students understand how modern JavaScript code is organised and prepared for production delivery.

Lesson 1 • React Fundamentals and JSX

Introduces React's component model, JSX syntax, and the virtual DOM. Establishes the mental model needed for all subsequent React state and lifecycle work.

Lesson 2 • State Management with Hooks

Covers useState, useEffect, useRef, and custom hooks for managing component state and side effects. Hooks are the primary mechanism for dynamic behaviour in modern React.

Lesson 3 • React Router and Navigation

Implements client-side routing with React Router, including nested routes and protected routes. Navigation patterns are required for any multi-page React application.

Lesson 4 • Fetching Data and API Integration

Integrates REST APIs into React using fetch, Axios, and React Query. Connects the frontend to backend services built in later chapters.

Lesson 1 • npm Ecosystem and Package Management

Teaches dependency management, semantic versioning, and publishing packages. Proper package hygiene prevents security vulnerabilities and version conflicts.

Lesson 2 • Streams and Buffers

Covers readable, writable, and transform streams for efficient data handling. Stream knowledge is critical for file uploads, proxies, and high-throughput APIs.

Lesson 3 • Node.js Runtime and Core Modules

Explores the Node.js event loop, module system, and built-in modules like fs, path, and os. Provides the runtime foundation for all backend code in the course.

Lesson 1 • Authentication and Authorization

Implements JWT-based authentication and role-based access control in Express. Security patterns here are reused across every protected route in the full-stack app.

Lesson 2 • Input Validation and Error Handling

Implements request validation with Joi or Zod and centralised error handling middleware. Robust validation and error responses are non-negotiable in production APIs.

Lesson 3 • API Testing and Documentation

Tests endpoints with Jest and Supertest and documents the API with OpenAPI/Swagger. Tested, documented APIs are a professional standard for team collaboration.

Lesson 4 • Middleware Architecture

Explains the middleware pipeline, built-in middleware, and third-party middleware integration. Middleware controls every cross-cutting concern in an Express application.

Lesson 1 • Relational Database Design

Covers normalisation, entity-relationship modelling, and primary/foreign key constraints. Sound schema design prevents data anomalies in production systems.

Lesson 2 • ORM with Prisma or Sequelize

Maps database tables to JavaScript models using an ORM and manages schema migrations. ORMs accelerate development and enforce schema consistency across environments.

Lesson 3 • Caching with Redis

Uses Redis for in-memory caching, session storage, and rate limiting. Caching reduces database load and improves API response times in production.

Lesson 4 • NoSQL with MongoDB and Mongoose

Designs document schemas, performs CRUD operations, and uses aggregation pipelines in MongoDB. NoSQL skills complement SQL for flexible, document-oriented data needs.

Lesson 1 • File Uploads and Media Handling

Implements multipart file uploads with Multer and stores assets in cloud object storage. File handling is a required feature in most real-world applications.

Lesson 2 • End-to-End Feature Development

Builds a complete feature from database schema through API endpoint to React UI. Integrates all prior skills into a single vertical slice of a production application.

Lesson 3 • Real-Time Communication with WebSockets

Builds bidirectional real-time features using Socket.IO on both server and client. Real-time capabilities differentiate modern applications from traditional request-response apps.

Lesson 4 • Server-Sent Events and Polling

Implements SSE for one-way server push and compares it with long polling. Choosing the right real-time strategy depends on use case and infrastructure constraints.

Lesson 1 • Containerisation with Docker

Packages Node.js and React apps into Docker containers and orchestrates them with Compose. Containers ensure environment parity between development and production.

Lesson 2 • Security Hardening for Production

Applies HTTPS, security headers, dependency auditing, and secrets management to production deployments. Security hardening is the final gate before any app serves real users.

Lesson 3 • Logging, Monitoring, and Alerting

Implements structured logging, metrics collection, and uptime alerting for production apps. Observability enables rapid diagnosis of failures before users are significantly impacted.

Lesson 4 • Cloud Deployment Strategies

Deploys containerised apps to cloud platforms using managed services and infrastructure-as-code. Cloud deployment skills are required for every professional full-stack role.
