Description:
TAKE YOUR WEBSOCKET SKILLS TO THE NEXT LEVEL!In this course, we will build a complete WebSocket server, using Node.js and JavaScript, from scratch.Many unique features.No libraries.No modules.We use ONLY pure Node.js and pure JavaScript to benefit YOU most.Don’t get hung up with large data. Step by step I’ll show you how to create a WebSocket application that receives large data from a client, and sends it back over a WebSocket connection. IMPORTANT: A huge advantage in my course is that you learn , how to send huge payloads . So you learn how to to manage chunking, streaming, and fragmentation properly. You may not get this information elsewhere.Key Focus AreasPure Node.js and JavaScript: Empower yourself. Master the art of building a WebSocket server from scratch, leveraging only the core capabilities of Node.js and JavaScript.Handling Large Payloads: Unlike other resources that focus on small to medium-sized payloads, this course will teach you how to manage chunking and fragmentation for large data transfers. This is a critical skill, as handling large payloads is a significant challenge that many developers shy away from.Real-World Application: Develop an application that can efficiently handle large data payloads, ensuring your WebSocket server is robust, scalable, and reliable.Such comprehensive and advanced course may not be available elsewhere. My course is dedicated to writing pure native server code that focuses on WebSockets. This course is particularly special because I show you how to handle sending and receiving large data payloads with WebSockets. . Most other courses or information on the web only focuses on small to medium sized payloads. That’s relatively easy to do. So, as has become my trademark or characteristic of my courses, I tackle the hard practical stuff to elevate your learning to the next level so that you benefit most.YOU NEED TO CATER FOR LARGE PAYLOADS WITH WEBSOCKETSOften a user needs to send several megabytes to gigabytes. So the available information and courses which limit the WebSocket data payloads to 65,535 bytes is inadequateThis is not good enough for you!Many modern applications, such as real-time analytics, file sharing, live updates, and multimedia streaming, involve transferring large amounts of data. If your WebSocket server cannot handle these large payloads, it may lead to performance issues, data loss, or even crashes.THE CHALLENGES IN BUILDING A WEBSOCKET SERVER FOR LARGE PAYLOADSWhile the WebSocket protocol itself is designed to handle continuous, bi-directional communication, building a server that efficiently handles large payloads can be challenging for several reasons:Protocol Complexity: The WebSocket protocol involves several layers of complexity, including message framing chunking and fragmentation. Understanding these nuances is essential for building a robust server.Buffering and Streaming: Large payloads often require efficient buffering and streaming mechanisms to prevent memory overflow and ensure smooth data transfer. Implementing these mechanisms correctly can be tricky.Error Handling: Large payloads increase the likelihood of errors during transmission. A well-designed server must include error handling mechanisms to manage and recover from such errors gracefully.My course is here to empower you, unashamedly.Why Knowing How to Build a fully-functional WebSocket server is a Game Changer for Web App Developers#1 Deep Understanding and Customization. Building a Node.js WebSocket server from scratch without using libraries is crucial for web developers because it provides a deep understanding of the underlying protocol and its mechanics. By implementing WebSockets purely in JavaScript, developers gain hands-on experience with the intricacies of real-time communication, including framing, chunking, working with readable streams, fragmentation, and error handling. This knowledge allows for better customization and optimization of the server to meet specific application needs, ensuring performance and scalability.#2. Mastering Core Concepts and Flexibility. Learning to build a WebSocket server from scratch also enhances problem-solving skills and flexibility. Without the abstraction of libraries, developers must handle every detail, from establishing connections to managing state and handling errors. This approach fosters a comprehensive understanding of the technology, enabling developers to troubleshoot and optimize their applications more effectively. Additionally, it allows for the creation of tailored solutions that can be adapted to various use cases, making the developer more versatile and proficient in handling complex real-time applications.THIS COURSE FOCUSES ON THE PURE WEBSOCKET PROTOCOL, INFORMATIVE, WITHOUT LIBRARIES.WHAT SKILLS ARE NEEDED?You need to have a basic idea of what WebSockets are. If you have never come across the term before, then I encourage you to take my WebSockets Protocol – Very Informative course. In that course, I take you through the WebSocket protocol from the basics through to the advanced.A basic knowledge of HTTP, HTML and JavaScript will also be helpful.WHAT YOU’LL LEARN IN THIS COURSEThis comprehensive course has unique content and will guide you through the entire process of building a Node.js WebSocket server from scratch, without relying on any libraries. You’ll gain a deep understanding of the WebSocket protocol and master its implementation on the server side.You’ll learn and master the WebSocket protocol, without relying on libraries.1. Creating the Initial HTTP Server:Start by setting up an HTTP server, which will serve as the foundation for your WebSocket connection.2. Implementing the Handshake Process:Learn how to calculate the Sec-WebSocket-Accept value on the server and send back the required headers to upgrade the HTTP connection to a WebSocket connection.3. Receiving WebSocket Data:Understand how to listen for data events on the WebSocket connection.Extract important information from WebSocket frames, including the FIN bit, opcode, and payload length fields.Learn how to extract the Masking Key from the client and use it to decrypt the received data.4. Sending WebSocket Data:Unpack the structure of WebSocket data frames.Construct and send binary frames to the client over the wire.5. Handling Closure Frames and the Closing Handshake:Learn how to process different types of WebSocket frames, including closure frames.Understand how to extract closure codes and reasons on both the client and server.Discover how to send a close frame to the client and gracefully close the underlying WebSocket connection in compliance with the RFC.ADVANCED CONCEPTS COVEREDBuffers and Bitwise Parsing: Master the use of buffers and bitwise operations to parse and construct WebSocket frames. These concepts are also used in most other programming languages like PHP, Python, C, C++, Java, etc, setting you up for success.Chunking and Fragmentation: Learn how to handle large payloads by chunking and fragmenting data in compliance with the WebSocket protocol.Reading and Writing to Buffers: Understand how to efficiently read from and write to buffers.SHA Hashing: Learn how to perform SHA-1 hashing for the WebSocket handshake.Examining Data Packets: Gain insights into examining and processing data packets using bitwise operators.Encrypting and Decrypting Data: Understand how to encrypt and decrypt data using the Masking Key and the modulus operator.AND TONS MORE!Why This Course Stands OutThe focus is on YOU. I try to benefit you most with practical skill. We learn together in a fun way. This course is uniquely dedicated to writing pure native server code for WebSockets, a topic often overlooked in favour of simpler, library-based solutions.By focusing on the complexities of large data payloads, you’ll gain a deep understanding of the WebSocket protocol and the skills to tackle even the most demanding real-time applicationsMeet Your Instructor: ClydeClyde is a coding enthusiast who has been immersed in the world of computers since the age of 7.With years of experience in web development and a passion for teaching, Clyde brings a wealth of knowledge and practical insights to the course.
