Node.js and React Native App Course

Lesson 1 • Setting Up the Node.js Environment

Installs and configures Node.js, npm, and essential CLI tools. Correct setup prevents environment errors throughout the course.

Lesson 2 • Project Structure and Coding Conventions

Defines folder organisation, naming conventions, and linting rules for a maintainable codebase. Consistent structure reduces onboarding friction for team projects.

Lesson 3 • Understanding the Full-Stack Architecture

Maps the relationship between a Node.js backend and a React Native frontend. Provides the mental model needed for every subsequent chapter.

Lesson 1 • Testing and Documenting the API

Writes unit and integration tests for API routes and generates interactive API documentation. Tested, documented APIs accelerate frontend development.

Lesson 2 • Authentication and Authorisation

Implements JWT-based authentication and role-based access control for learners and instructors. Secure auth protects all protected API routes.

Lesson 3 • Connecting to a Database

Integrates a relational or document database to persist educational content and user progress. Students write models and perform CRUD operations.

Lesson 4 • Designing RESTful API Endpoints

Applies REST principles to design endpoints for courses, lessons, and users. Proper API design ensures clean integration with the React Native frontend.

Lesson 1 • Handling User Input and Forms

Builds controlled form components using TextInput, Switch, and Picker. Input handling is essential for login, quiz, and search screens.

Lesson 2 • Building Reusable Component Library

Extracts common UI patterns into a shared component library with documented props. Reusable components speed up screen development in later chapters.

Lesson 3 • Styling with StyleSheet and Flexbox

Applies React Native's StyleSheet API and Flexbox layout model to position and size components. Consistent styling patterns prevent layout bugs across screen sizes.

Lesson 1 • React Hooks for Local State

Uses useState, useReducer, and useEffect to manage component-level state and side effects. These hooks underpin every stateful feature in the app.

Lesson 2 • Offline Support and Local Persistence

Stores critical data locally so learners can access content without a network connection. Offline capability is a key differentiator for educational mobile apps.

Lesson 3 • Global State with Context API

Implements a Context-based store for authentication state and user preferences. Context avoids prop drilling across deeply nested screen trees.

Lesson 1 • Authentication Flow and Protected Routes

Conditionally renders auth or app navigators based on JWT presence. Protecting routes prevents unauthorised access to course content.

Lesson 2 • Stack and Tab Navigators

Builds a native stack navigator for lesson flows and a bottom tab navigator for main sections. Combining navigators creates intuitive app structure.

Lesson 3 • React Navigation Core Concepts

Installs React Navigation and configures a root navigator with typed route params. Navigation architecture determines the entire user journey through the app.

Lesson 1 • Progress Tracking and Dashboards

Displays learner progress with charts and completion badges on a personal dashboard. Progress data is fetched from the backend and visualised in real time.

Lesson 2 • Lesson Content Player

Renders text, image, and video lesson content with a progress indicator. The player tracks completion and sends updates to the backend.

Lesson 3 • Notifications and Reminders

Sends local and push notifications to remind learners of incomplete lessons and upcoming deadlines. Notifications are scheduled on the backend and delivered via a push service.

Lesson 4 • Quiz and Assessment Engine

Implements multiple-choice and short-answer quizzes with immediate feedback and scoring. Quiz results are persisted to the backend for instructor review.

Lesson 1 • Optimising Component Rendering

Applies React.memo, useMemo, and useCallback to eliminate unnecessary re-renders. Render optimisation directly improves scroll and animation smoothness.

Lesson 2 • Profiling React Native Performance

Uses the React Native Profiler and Flipper to identify slow renders and JS thread bottlenecks. Profiling before optimising prevents wasted effort on non-critical paths.

Lesson 3 • Reducing Bundle Size and Load Time

Applies code splitting, lazy imports, and asset optimisation to shrink the app bundle. Smaller bundles reduce install size and improve cold-start time.

Lesson 1 • End-to-End Testing Strategy

Writes end-to-end tests that simulate real learner journeys across the full stack. E2E tests catch integration regressions before they reach production.

Lesson 2 • Continuous Integration Pipeline

Configures a CI pipeline that runs linting, unit tests, and E2E tests on every pull request. Automated checks enforce code quality standards across the team.

Lesson 3 • Deploying the Node.js Backend

Containerises the Express server with Docker and deploys it to a cloud platform. A reliable backend deployment ensures the mobile app always has a live API.

Lesson 4 • Monitoring and Crash Reporting

Integrates error tracking and analytics tools to monitor the live app after release. Proactive monitoring reduces mean time to resolution for production issues.
