Modern course on Node.js in 2020.

Dear engineer colleagues, the Metarkhya community presents to your attention a modern курс по Node.js, which includes an in-depth analysis of all the capabilities and aspects of the platform. The primary focus is on how to create reliable, high-load application servers and APIs without tying to a specific framework or even protocol, i.e., abstracting business logic into a separate layer. Attached to the lectures are numerous code examples demonstrating the flexible structure of applications and architectural techniques, including working with databases through a data access layer, creating interactive applications using websockets, ensuring security, graceful shutdown, inter-process communication, preventing memory leaks, scaling, and clustering through processes and threads. Currently, there are 38 lectures in the course (about 35.5 hours of video), 37 repositories with code examples, and 4 PDFs with slides. Before the main part of the Node.js course, you should first master at least partially the course on asynchronous programming.
