What You Will Learn

Master TypeScript static typing fundamentals, inference engines, and structural subtyping semantics.
Write clean, idiomatic interfaces and type aliases enforcing strict data contracts across frontend and backend boundaries.
Architect reusable generic libraries and pipelines utilizing generic constraints, keyof, and mapped types.
Formulate conditional types, distributed unions, template literal types, and compile-time infer assertions.
Eliminate runtime type errors with discriminated union event structures and exhaustive never-type checks.
Configure production-grade tsconfig pipelines adhering to strict compiler standards and modern NodeNext module resolution.
Implement enterprise design patterns with classes, private properties, decorators, and abstract base architectures.
Bridge compile-time guarantees with runtime safety using schema validation engines such as Zod.
Build end-to-end type-safe AI agent SDKs handling streaming responses, structured tool calling, and defensive error boundaries.
Complete 5 production portfolio projects and pass the Module 12 Capstone Challenge evaluated by the TypeScript Mastery Agent.

Curriculum & Weekly Roadmap

12 Structured Modules

Module 1 — Foundations of Static Typing & Modern TypeScript

  • JavaScript Limitations vs TypeScript Design Philosophy

  • Basic Primitive Types, Any vs Unknown, and Void vs Never

Module 2 — Interfaces, Type Aliases & Structural Typing

  • Defining Shape Contracts: Interface vs Type Alias Trade-offs
  • Duck Typing & Structural Subtyping Mechanics
  • Optional, Readonly, Index Signatures & Declaration Merging

Module 3 — Functions, Signatures & Generics Foundations

  • Function Signatures, Call Signatures & Constructor Types
  • Function Overloads, Parameter Destructuring & Return Guarantees
  • Introduction to Generics: Type Parameters & Reusable Contracts

Module 4 — Advanced Generics & Conditional Types

  • Generic Constraints (`T extends U`) & Keyof Operators
  • Conditional Types (`T extends U ? X : Y`) & the `infer` Keyword
  • Distributive Conditional Types & Template Literal String Types

Module 5 — Union, Intersection & Discriminated Unions

  • Union Types (`|`) vs Intersection Types (`&`)
  • Discriminated Unions (Tagged Unions) Pattern
  • Exhaustive Checks with the `never` Type Safeguard

Module 6 — Utility Types & Advanced Type Transformations

  • Built-in Utility Types: Partial, Required, Readonly, Record
  • Filtering Utilities: Pick, Omit, Exclude, Extract, NonNullable
  • Function Utilities: ReturnType, Parameters, and Custom Mapped Types

Module 7 — TypeScript Compiler Configuration & Tooling

  • Deep Dive into `tsconfig.json`: Strict Mode Flags Explained
  • Compiler Targets, Lib Definitions & Polyfill Strategies
  • Source Maps, Project References & Incremental Compilation

Module 8 — Module Systems, Monorepos & Declaration Files

  • CommonJS vs ESM: Modern NodeNext Module Resolution
  • Path Aliases, Barrel Exports & Tree-Shaking Implications
  • Writing Declaration Files (`.d.ts`) & Ambient Namespaces

Module 9 — Object-Oriented TypeScript & Design Patterns

  • Classes, Visibility Modifiers, Parameter Properties & Getters/Setters
  • Abstract Classes vs Interfaces & Polymorphism
  • Modern Stage-3 Decorators & Dependency Injection Patterns

Module 10 — Node.js & Backend TypeScript Architecture

  • Setting Up Node.js with TypeScript (`tsx`, `ts-node`, `esbuild`)
  • Type-Safe REST APIs with Express / Fastify and Clean Architecture
  • Database Typing with Prisma, Drizzle, and Strong Typed Queries

Module 11 — Runtime Validation & Defensive Type Boundaries

  • The Compile-Time vs Runtime Type Boundary Gap
  • Runtime Schema Validation with Zod & Type Inference (`z.infer`)
  • Parsing vs Casting: Validating API Payloads and Environment Variables

Module 12 — Type-Safe AI Agent SDK & Capstone Evaluation

  • Architecting Type-Safe AI Agent Schemas & Structured Output
  • Compile-Time Type-Safe Tool Calling & Function Orchestration
  • Module 12 Capstone Challenge Submission & TypeScript Mastery Agent Evaluation
