Modern Node.js course in 2020

Dear fellow engineers, the Metarchia community presents to your attention a modern Node.js course, which includes a deep analysis of all the features and aspects of the platform. The main focus is on how to create reliable high-load application servers and APIs without being tied to a specific framework and even protocol, i.e. abstract business logic into a separate layer. Many code examples are attached to the lectures, demonstrating flexible application structure and architectural techniques, including working with a DBMS through a data access layer, creating interactive applications on web sockets, security, graceful shutdown, interprocess communication, preventing memory leaks, scaling and clustering when help processes and threads. Currently there are 38 lectures in the course (about 35 and ½ hours of video), 37 code sample repositories, 4 PDFs with slides. Before the main part of the Node.js course, you must first master at least partially asynchronous programming course.
