Overview

This course provides a guide to building backend systems with Node.js and TypeScript, combining strong typing with modern server-side practices. It demonstrates how TypeScript improves reliability, security, and scalability in backend projects by enforcing type safety and consistency across routes, middleware, databases, and authentication flows. Through hands-on lessons and real-world demonstrations, you’ll start by setting up Node.js projects with TypeScript, configuring linting, formatting, and logging tools. You will then learn to build secure and maintainable servers using Express, define typed APIs and middleware, and implement error handling patterns. The course progresses to integrating MongoDB with Mongoose, where you’ll create typed schemas, models, and perform CRUD operations with validation, indexing, and transactions. Finally, you’ll explore authentication with JWTs, role-based access control (RBAC), and automated testing with Jest to ensure backend reliability. By the end of this course, you will be able to: Initialize and configure Node.js projects with TypeScript, ESLint, Prettier, and strict compiler settings. Build Express servers with typed routes, middleware, error handling, and APIs. Design and validate MongoDB schemas and models with Mongoose in TypeScript. Perform CRUD operations, query optimization, and transactions with strong typing. Implement secure authentication using JWTs and enforce role-based access control. Write unit and integration tests with Jest to validate controllers, routes, and database operations. Develop a production-ready backend system where TypeScript ensures maintainability, security, and long-term scalability. This course is ideal for JavaScript and Node.js developers who want to strengthen their backend skills with enterprise-level TypeScript practices. A solid understanding of JavaScript, Node.js basics, and OOP in TypeScript is recommended before starting. Join us to master backend development with TypeScript and learn how to design secure, scalable, and production-grade APIs!

Syllabus

Setting Up Node.js with TypeScript

This module introduces you to building Node.js applications with TypeScript. You’ll learn the importance of TypeScript in backend development, how to initialize a Node.js project, and set up a clean development environment with ESLint and Prettier. Through guided demos, you’ll install and configure TypeScript, define project folder structures, and implement basic logging and monitoring practices. By the end, you’ll have a solid foundation for starting TypeScript-based Node.js projects with best practices in place.

NoSQL Database with TypeScript

This module focuses on integrating MongoDB, a popular NoSQL database, with TypeScript applications using Mongoose. You’ll start by learning the fundamentals of MongoDB and how to set up local and cloud-based databases. Then, you’ll create schemas and models with Mongoose, validate data, and implement CRUD operations in TypeScript. Advanced topics such as query optimization, indexing, aggregation pipelines, and transactions will help you build scalable and efficient database solutions. By the end, you’ll be able to design and manage NoSQL databases seamlessly within your Node.js projects.

Building Secure APIs with Auth and Roles

This module covers the critical aspects of securing Node.js applications. You’ll begin by implementing JSON Web Token (JWT)-based authentication to protect your APIs. Next, you’ll learn to design role-based access control (RBAC) and apply middleware to restrict access based on user roles. Finally, you’ll explore testing strategies using Jest, including writing unit tests, mocking database calls, and testing API endpoints. By the end of this module, you’ll be able to develop production-ready, secure APIs with robust authentication, authorization, and automated test coverage.

Course Wrap-Up and Assessment

This module covers the consolidation of all concepts learned throughout the course. You will review key takeaways, complete a guided practice project, and test your knowledge with assessments, ensuring you can confidently apply TypeScript in Backend development with Typescript.
