No previous experience of Redis is required! Redis is an in-memory data store purpose built for solving caching needs. You will be one of the engineers who can clearly articulate the performance profile of Node and its Event Loop.Ĭaching with Redis: We'll also supercharge the performance of database queries by implementing caching backed by Redis. Many engineers know not to 'block' the Event Loop, but they don't necessarily understand why.

Besides being critical for interviews, knowledge of the Event Loop will give you a better understanding of how Node works internally. Node Internals: Here's one of the most common interview questions you'll face when looking for a Node job: ' Can you e xplain Node's Event Loop?' There are two types of engineers: those who can describe the Event Loop and those who cannot! This course will ensure that you are incredibly well prepared to answer that most important question. This is a must-take course if you work with Node. Query Caching with Redis? You will learn it. Go beyond the basics of Node! This course will give you the skills needed to become a top Node engineer.
