Course Outline

? Day 1: TypeScript Fundamentals and Advanced Types

Session 1: Introduction and Setup

• Why TypeScript for large apps? Benefits and challenges
• Configuring TypeScript compiler (tsconfig.json)
• TypeScript in modern development environments

Session 2: Core Type System

• Primitive and complex types
• Interfaces vs. type aliases
• Union, intersection, and literal types

Session 3: Advanced Types and Generics

• Generics in functions, interfaces, and classes
• Conditional types and mapped types
• Utility types and type guards

Lab Activities:

• Set up a TypeScript project with strict type checking
• Implement interfaces and generic data structures
• Create type-safe utility functions with advanced types

? Day 2: Architecture, Modules, and Tooling

Session 1: Modular Architecture and Code Organization

• Namespaces vs modules (ES modules)
• Organizing large codebases: folder structures and index files
• Dependency management and circular dependencies

Session 2: Tooling and Build Process

• Integrating TypeScript with Webpack, Rollup, or ESBuild
• Using linters and formatters (TSLint/ESLint, Prettier)
• Source maps and debugging in large projects

Session 3: Integration with Frameworks

• Using TypeScript with React, Angular, or Node.js
• Typing external libraries and declaration files
• Managing ambient types and DefinitelyTyped

Lab Activities:

• Build a modular app scaffold with clear separation of concerns
• Configure build tools and linters for TypeScript projects
• Add types to JavaScript libraries and third-party modules

? Day 3: Testing, Deployment, and Best Practices

Session 1: Testing TypeScript Applications

• Unit testing frameworks (Jest, Mocha) with TypeScript
• Mocking and typing tests
• Writing type-safe test cases and integration tests

Session 2: Performance and Code Quality

• TypeScript compiler optimizations and incremental builds
• Managing large declaration files and typings
• Best practices for maintainability and scalability

Session 3: Continuous Integration and Deployment

• Integrating TypeScript builds in CI/CD pipelines
• Error reporting and monitoring in production
• Preparing TypeScript projects for production deployment

Lab Activities:

• Write comprehensive unit and integration tests
• Set up CI/CD pipeline with automated builds and tests
• Optimize and deploy a large-scale TypeScript application
