Query Caching with Redis? You will learn it. The Node Event Loop? Included. Scalable File Upload? Of course!
This is a must-take course if you work with Node.
Node Internals: Here's one of the most common interview questions you'll face when looking for a Node job: "Can you explain 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. Besides being critical for interviews, knowledge of the Event Loop will give you a better understanding of how Node works internally. Many engineers know not to 'block' the Event Loop, but they don't necessarily understand why. You will be one of the engineers who can clearly articulate the performance profile of Node and its Event Loop.
Caching with Redis: We'll also supercharge the performance of database queries by implementing caching backed by Redis. No previous experience of Redis is required! Redis is an in-memory data store purpose built for solving caching needs. By adding caching to your application, you can decrease the amount of time that any given request takes, improving the overall response time of your app.
File Upload: There are many resources online that offer suggestions on how to handle file upload, but few show a solution that can truly scale. Hint: saving files directly on your server isn't a scalable solution! Learn how to leverage AWS S3 to implement file upload that can scale to millions of users with a few dozen lines of simple code. Plentiful discussions are included on security concerns with handling uploads, as well.
Here's what we'll learn:
- Master the Node Event Loop - understand how Node executes your source code.
- Understand the purpose of Node, and how the code you write is eventually executed by C++ code in the V8 engine
- Add a huge boost to performance in your Node app through clustering and worker threads
- Turbocharge MongoDB queries by adding query caching backed by a lightning-fast Redis instance
- Scale your app to infinity with image and file upload backed by Amazon's S3 file service
- Implement a continuous integration testing pipeline so you always know your project functions properly
- Think you know everything there is about managing cookies and session? Well, you might, but learn even more!
- Ensure your app works the way you expect with automated browser testing using Jest and Puppeteer
- Bonus - learn advanced JS techniques along the way, including where to use ES2015 proxies!
- Anyone who wants a deep mastery of Node
- Engineers looking to understand the internals of Node
- Programmers looking to improve Node's performance
