Description

In this hands-on, project-based course, we’ll guide you step-by-step through building a complete RESTful API from scratch. Our main project will be a versatile Product API, demonstrating how to perform all essential CRUD (Create, Read, Update, Delete) operations. You won’t just learn theory; you’ll build, test, and understand every line of code.

We’ll leverage the industry-standard Express.js framework to create robust and scalable server-side applications. Beyond just handling requests, you’ll master how to seamlessly integrate with relational databases using Sequelize ORM. What sets this course apart is its flexibility: you’ll learn to work with both MySQL, a popular choice for production environments, and SQLite3, excellent for local development and testing, all configurable through simple environment variables.

Embrace modern JavaScript with us! This course fully utilizes ES Modules (import/export syntax), ensuring you’re coding with the latest standards. We’ll also cover crucial backend practices like securely managing environment variables with dotenv and implementing effective error handling to make your APIs robust and reliable. By the end of this course, you’ll have a solid foundation in Node.js backend development, a practical project for your portfolio, and the confidence to tackle more complex API challenges.

What you’ll learn in this course:

Master Node.js Fundamentals: Understand how Node.js works as a JavaScript runtime, its event-driven architecture, and how to execute server-side JavaScript.
Build Robust RESTful APIs with Express.js: Learn to design, implement, and test all four core HTTP methods (GET, POST, PUT, DELETE) to create powerful and well-structured API endpoints.
Database Integration with Sequelize ORM: Set up and configure Sequelize to connect your Node.js application to both MySQL and SQLite3 databases, demonstrating flexibility for different project needs.
Perform CRUD Operations: Gain practical experience creating, reading, updating, and deleting data records in your database through your API, a fundamental skill for any backend developer.
Model Database Schemas: Define and manage your database tables and relationships efficiently using Sequelize models, ensuring data integrity and consistency.
Utilize Modern JavaScript (ES Modules): Write clean, maintainable code using the contemporary import and export syntax, preparing you for modern JavaScript development practices.
Manage Environment Variables Securely: Learn how to use dotenv to handle sensitive information and configurations, keeping your application credentials safe and adaptable.
Implement Effective Error Handling: Develop strategies to catch and respond to errors gracefully within your API, providing meaningful feedback to clients.
Structure Node.js Projects: Understand best practices for organizing your backend code into a clean, modular, and scalable project structure.
Develop a Complete Product API: Build a fully functional product management API from scratch, serving as a robust portfolio piece and a foundation for your future projects.
