This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Mastering design patterns in Node.js is an essential skill for developing maintainable and scalable applications. This course will guide you through the core principles of design patterns, from creational and structural to behavioral and advanced patterns, using real-world Node.js examples. By learning these patterns, you will enhance your ability to write cleaner code, manage dependencies effectively, and build robust systems. The course is divided into eight comprehensive modules, starting with an introduction to the prerequisites and course structure. You’ll explore various design patterns in-depth, from the Singleton and Factory patterns to the Strategy and State patterns. The course also covers advanced topics such as asynchronous task cancellation and asynchronous initialization, demonstrating how to handle concurrency and manage asynchronous workflows efficiently. The journey will take you through practical examples and case studies that challenge you to think critically and apply these patterns in real-world situations. This course is ideal for developers who have a basic understanding of Node.js and wish to deepen their knowledge of design patterns. It is suitable for intermediate-level learners looking to sharpen their skills in building scalable and maintainable software systems. Familiarity with JavaScript and basic web development concepts is recommended. By the end of the course, you will be able to apply design patterns such as Singleton, Factory, and Observer in Node.js, manage asynchronous flows with async/await and promises, and enhance your application's performance and scalability through advanced patterns.

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Mastering Streams in Node.js will equip you with in-depth knowledge and hands-on experience in working with streams, one of the most powerful features of Node.js. You will explore the difference between buffers and streams, and learn how to efficiently handle data flow in real-time applications. This course will also cover a wide range of streams, from readable and writable streams to advanced topics like piping, backpressure, and streaming large files. The course is divided into distinct modules that cover fundamentals like how streams work, how to manage data efficiently, and how to apply modern APIs like WebStreams for enhanced browser interaction. As you progress, you'll gain a practical understanding of how to apply streams in real-world scenarios like uploading files, streaming content to browsers, and handling HTTP range requests. You'll even explore advanced techniques like streaming from databases, transforming data, and building custom writable streams for server-client communication. This course is perfect for developers looking to gain mastery over one of the most powerful and versatile features of Node.js. Ideal for intermediate JavaScript developers with some Node.js experience, it will guide you through concepts like backpressure and real-time streaming, which are crucial for modern web and backend applications. By the end of the course, you will be able to understand and implement a variety of stream-based solutions for data processing, server-client communication, and performance optimization in Node.js applications.

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. In this course, you'll dive deep into the concepts of performance optimization and scalability in Node.js applications. Whether you're a developer aiming to build high-performing applications or an architect looking to scale a system efficiently, this course provides the essential tools and techniques. Through a hands-on approach, you will explore both theory and practice to build robust and scalable applications. You'll begin by understanding the fundamental principles of scalability and performance, such as vertical and horizontal scaling, and application cloning. As you move through the course, you'll learn to implement child processes and process pools to improve concurrency, along with fault tolerance strategies to ensure resilience. The journey also includes leveraging external tools and strategies for scaling databases and partitioning large datasets to meet growing demands. In the second half of the course, you’ll work through parallelizing asynchronous operations with child processes, learning to merge streams and handle errors seamlessly. Additionally, you'll explore batching and caching techniques to optimize async workloads and prevent performance bottlenecks. The final module focuses on managing CPU-intensive operations and understanding the use of child processes and worker threads for offloading expensive computations. This course is ideal for backend developers, Node.js developers, and system architects who want to optimize application performance. Prerequisites include basic JavaScript and Node.js knowledge, along with an understanding of asynchronous programming. The difficulty level is intermediate. By the end of the course, you will be able to scale Node.js applications using both vertical and horizontal scaling, implement parallel processing with child processes, optimize async operations through batching and caching, and manage CPU-heavy tasks effectively.
